Ksymoops
--------
If the unthinkable happens and your kernel oopses, you'll need a 2.4
version of ksymoops to decode the report; see REPORTING-BUGS in the
root of the Linux source for more information.
If the unthinkable happens and your kernel oopses, you may need the
ksymoops tool to decode it, but in most cases you don't.
In the 2.6 kernel it is generally preferred to build the kernel with
CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is
(this also produces better output than ksymoops).
If for some reason your kernel is not build with CONFIG_KALLSYMS and
you have no way to rebuild and reproduce the Oops with that option, then
you can still decode that Oops with ksymoops.

RapidIO is a high speed switched fabric interconnect with
features aimed at the embedded market. RapidIO provides
support for memory-mapped I/O as well as message-based
transactions over the switched fabric network. RapidIO has
a standardized discovery mechanism not unlike the PCI bus

For the case where the PCI subsystem re-assigned these MSI-X vectors

5.4 Handling function implementing both MSI and MSI-X capabilities
For the case where a function implements both MSI and MSI-X
capabilities, the PCI subsystem enables a device to run either in MSI
mode or MSI-X mode but not both. A device driver determines whether it
wants MSI or MSI-X enabled on its hardware device. Once a device
driver requests for MSI, for example, it is prohibited to request for
driver requests for MSI, for example, it is prohibited from requesting
MSI-X; in other words, a device driver is not permitted to ping-pong
between MSI mod MSI-X mode during a run-time.
5.5 Hardware requirements for MSI/MSI-X support
MSI/MSI-X support requires support from both system hardware and
individual hardware device functions.
5.5.1 System hardware support
Since the target of MSI address is the local APIC CPU, enabling
MSI/MSI-X support in Linux kernel is dependent on whether existing
system hardware supports local APIC. Users should verify their
system whether it runs when CONFIG_X86_LOCAL_APIC=y.
MSI/MSI-X support in the Linux kernel is dependent on whether existing
system hardware supports local APIC. Users should verify that their
system supports local APIC operation by testing that it runs when
CONFIG_X86_LOCAL_APIC=y.
In SMP environment, CONFIG_X86_LOCAL_APIC is automatically set;
however, in UP environment, users must manually set
CONFIG_X86_LOCAL_APIC. Once CONFIG_X86_LOCAL_APIC=y, setting
CONFIG_PCI_MSI enables the VECTOR based scheme and
the option for MSI-capable device drivers to selectively enable
MSI/MSI-X.
CONFIG_PCI_MSI enables the VECTOR based scheme and the option for
MSI-capable device drivers to selectively enable MSI/MSI-X.
Note that CONFIG_X86_IO_APIC setting is irrelevant because MSI/MSI-X
vector is allocated new during runtime and MSI/MSI-X support does not
depend on BIOS support. This key independency enables MSI/MSI-X
support on future IOxAPIC free platform.
support on future IOxAPIC free platforms.
5.5.2 Device hardware support
The hardware device function supports MSI by indicating the
MSI/MSI-X capability structure on its PCI capability list. By
default, this capability structure will not be initialized by
the kernel to enable MSI during the system boot. In other words,
the device function is running on its default pin assertion mode.
Note that in many cases the hardware supporting MSI have bugs,
which may result in system hang. The software driver of specific
MSI-capable hardware is responsible for whether calling
which may result in system hangs. The software driver of specific
MSI-capable hardware is responsible for deciding whether to call
pci_enable_msi or not. A return of zero indicates the kernel

device function. The device function is now running on MSI/MSI-X mode.

SCSI error handling for tape drives and medium changers
-------------------------------------------------------
The linux SCSI mid layer provides an error handling protocol which
kicks into gear whenever a SCSI command fails to complete within a
certain amount of time (which can vary depending on the command).
The cciss driver participates in this protocol to some extent. The
normal protocol is a four step process. First the device is told
to abort the command. If that doesn't work, the device is reset.
If that doesn't work, the SCSI bus is reset. If that doesn't work
the host bus adapter is reset. Because the cciss driver is a block
driver as well as a SCSI driver and only the tape drives and medium
changers are presented to the SCSI mid layer, and unlike more
straightforward SCSI drivers, disk i/o continues through the block
side during the SCSI error recovery process, the cciss driver only
implements the first two of these actions, aborting the command, and
resetting the device. Additionally, most tape drives will not oblige
in aborting commands, and sometimes it appears they will not even
obey a reset coommand, though in most circumstances they will. In
the case that the command cannot be aborted and the device cannot be
reset, the device will be set offline.
In the event the error handling code is triggered and a tape drive is
successfully reset or the tardy command is successfully aborted, the
tape drive may still not allow i/o to continue until some command
is issued which positions the tape to a known position. Typically you
must rewind the tape (by issuing "mt -f /dev/st0 rewind" for example)
before i/o can proceed again to a tape drive which was reset.

The Framebuffer Console
=======================
The framebuffer console (fbcon), as its name implies, is a text
console running on top of the framebuffer device. It has the functionality of
any standard text console driver, such as the VGA console, with the added
features that can be attributed to the graphical nature of the framebuffer.
In the x86 architecture, the framebuffer console is optional, and
some even treat it as a toy. For other architectures, it is the only available
display device, text or graphical.
What are the features of fbcon? The framebuffer console supports
high resolutions, varying font types, display rotation, primitive multihead,
etc. Theoretically, multi-colored fonts, blending, aliasing, and any feature
made available by the underlying graphics card are also possible.
A. Configuration
The framebuffer console can be enabled by using your favorite kernel
configuration tool. It is under Device Drivers->Graphics Support->Support for
framebuffer devices->Framebuffer Console Support. Select 'y' to compile
support statically, or 'm' for module support. The module will be fbcon.
In order for fbcon to activate, at least one framebuffer driver is
required, so choose from any of the numerous drivers available. For x86
systems, they almost universally have VGA cards, so vga16fb and vesafb will
always be available. However, using a chipset-specific driver will give you
more speed and features, such as the ability to change the video mode
dynamically.
To display the penguin logo, choose any logo available in Logo
Configuration->Boot up logo.
Also, you will need to select at least one compiled-in fonts, but if
you don't do anything, the kernel configuration tool will select one for you,
usually an 8x16 font.
GOTCHA: A common bug report is enabling the framebuffer without enabling the
framebuffer console. Depending on the driver, you may get a blanked or
garbled display, but the system still boots to completion. If you are
fortunate to have a driver that does not alter the graphics chip, then you
will still get a VGA console.
B. Loading
Possible scenarios:
1. Driver and fbcon are compiled statically
Usually, fbcon will automatically take over your console. The notable
exception is vesafb. It needs to be explicitly activated with the
vga= boot option parameter.
2. Driver is compiled statically, fbcon is compiled as a module
Depending on the driver, you either get a standard console, or a
garbled display, as mentioned above. To get a framebuffer console,
do a 'modprobe fbcon'.
3. Driver is compiled as a module, fbcon is compiled statically
You get your standard console. Once the driver is loaded with
'modprobe xxxfb', fbcon automatically takes over the console with
the possible exception of using the fbcon=map:n option. See below.
4. Driver and fbcon are compiled as a module.
You can load them in any order. Once both are loaded, fbcon will take
over the console.
C. Boot options
The framebuffer console has several, largely unknown, boot options
that can change its behavior.
1. fbcon=font:<name>
Select the initial font to use. The value 'name' can be any of the
compiled-in fonts: VGA8x16, 7x14, 10x18, VGA8x8, MINI4x6, RomanLarge,
SUN8x16, SUN12x22, ProFont6x11, Acorn8x8, PEARL8x8.
Note, not all drivers can handle font with widths not divisible by 8,
such as vga16fb.
2. fbcon=scrollback:<value>[k]
The scrollback buffer is memory that is used to preserve display
contents that has already scrolled past your view. This is accessed
by using the Shift-PageUp key combination. The value 'value' is any
integer. It defaults to 32KB. The 'k' suffix is optional, and will
multiply the 'value' by 1024.
3. fbcon=map:<0123>
This is an interesting option. It tells which driver gets mapped to
which console. The value '0123' is a sequence that gets repeated until
the total length is 64 which is the number of consoles available. In
the above example, it is expanded to 012301230123... and the mapping
will be:
tty | 1 2 3 4 5 6 7 8 9 ...
fb | 0 1 2 3 0 1 2 3 0 ...
('cat /proc/fb' should tell you what the fb numbers are)
One side effect that may be useful is using a map value that exceeds
the number of loaded fb drivers. For example, if only one driver is
available, fb0, adding fbcon=map:1 tells fbcon not to take over the
console.
Later on, when you want to map the console the to the framebuffer
device, you can use the con2fbmap utility.
4. fbcon=vc:<n1>-<n2>
This option tells fbcon to take over only a range of consoles as
specified by the values 'n1' and 'n2'. The rest of the consoles
outside the given range will still be controlled by the standard
console driver.
NOTE: For x86 machines, the standard console is the VGA console which
is typically located on the same video card. Thus, the consoles that
are controlled by the VGA console will be garbled.
4. fbcon=rotate:<n>
This option changes the orientation angle of the console display. The
value 'n' accepts the following:
0 - normal orientation (0 degree)
1 - clockwise orientation (90 degrees)
2 - upside down orientation (180 degrees)
3 - counterclockwise orientation (270 degrees)
The angle can be changed anytime afterwards by 'echoing' the same
numbers to any one of the 2 attributes found in
/sys/class/graphics/fb{x}
con_rotate - rotate the display of the active console
con_rotate_all - rotate the display of all consoles
Console rotation will only become available if Console Rotation
Support is compiled in your kernel.
NOTE: This is purely console rotation. Any other applications that
use the framebuffer will remain at their 'normal'orientation.
Actually, the underlying fb driver is totally ignorant of console

RCU-based dcache locking model
==============================
On many workloads, the most common operation on dcache is to look up a
dentry, given a parent dentry and the name of the child. Typically,
for every open(), stat() etc., the dentry corresponding to the
pathname will be looked up by walking the tree starting with the first
component of the pathname and using that dentry along with the next
component to look up the next level and so on. Since it is a frequent
operation for workloads like multiuser environments and web servers,
it is important to optimize this path.
Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in
every component during path look-up. Since 2.5.10 onwards, fast-walk
algorithm changed this by holding the dcache_lock at the beginning and
walking as many cached path component dentries as possible. This
significantly decreases the number of acquisition of
dcache_lock. However it also increases the lock hold time
significantly and affects performance in large SMP machines. Since
2.5.62 kernel, dcache has been using a new locking model that uses RCU
to make dcache look-up lock-free.
The current dcache locking model is not very different from the
existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock
protected the hash chain, d_child, d_alias, d_lru lists as well as
d_inode and several other things like mount look-up. RCU-based changes
affect only the way the hash chain is protected. For everything else
the dcache_lock must be taken for both traversing as well as
updating. The hash chain updates too take the dcache_lock. The
significant change is the way d_lookup traverses the hash chain, it
doesn't acquire the dcache_lock for this and rely on RCU to ensure
that the dentry has not been *freed*.
Dcache locking details
======================
For many multi-user workloads, open() and stat() on files are very
frequently occurring operations. Both involve walking of path names to
find the dentry corresponding to the concerned file. In 2.4 kernel,
dcache_lock was held during look-up of each path component. Contention
and cache-line bouncing of this global lock caused significant
scalability problems. With the introduction of RCU in Linux kernel,
this was worked around by making the look-up of path components during
path walking lock-free.
Safe lock-free look-up of dcache hash table
===========================================
Dcache is a complex data structure with the hash table entries also
linked together in other lists. In 2.4 kernel, dcache_lock protected
all the lists. We applied RCU only on hash chain walking. The rest of
the lists are still protected by dcache_lock. Some of the important
changes are :
1. The deletion from hash chain is done using hlist_del_rcu() macro
which doesn't initialize next pointer of the deleted dentry and
this allows us to walk safely lock-free while a deletion is
happening.
2. Insertion of a dentry into the hash table is done using
hlist_add_head_rcu() which take care of ordering the writes - the
writes to the dentry must be visible before the dentry is
inserted. This works in conjunction with hlist_for_each_rcu() while
walking the hash chain. The only requirement is that all
initialization to the dentry must be done before
hlist_add_head_rcu() since we don't have dcache_lock protection
while traversing the hash chain. This isn't different from the
existing code.
3. The dentry looked up without holding dcache_lock by cannot be
returned for walking if it is unhashed. It then may have a NULL
d_inode or other bogosity since RCU doesn't protect the other
fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
indicate unhashed dentries and use this in conjunction with a
per-dentry lock (d_lock). Once looked up without the dcache_lock,
we acquire the per-dentry lock (d_lock) and check if the dentry is
unhashed. If so, the look-up is failed. If not, the reference count
of the dentry is increased and the dentry is returned.
4. Once a dentry is looked up, it must be ensured during the path walk
for that component it doesn't go away. In pre-2.5.10 code, this was
done holding a reference to the dentry. dcache_rcu does the same.
In some sense, dcache_rcu path walking looks like the pre-2.5.10
version.
5. All dentry hash chain updates must take the dcache_lock as well as
the per-dentry lock in that order. dput() does this to ensure that
a dentry that has just been looked up in another CPU doesn't get
deleted before dget() can be done on it.
6. There are several ways to do reference counting of RCU protected
objects. One such example is in ipv4 route cache where deferred
freeing (using call_rcu()) is done as soon as the reference count
goes to zero. This cannot be done in the case of dentries because
tearing down of dentries require blocking (dentry_iput()) which
isn't supported from RCU callbacks. Instead, tearing down of
dentries happen synchronously in dput(), but actual freeing happens
later when RCU grace period is over. This allows safe lock-free
walking of the hash chains, but a matched dentry may have been
partially torn down. The checking of DCACHE_UNHASHED flag with
d_lock held detects such dentries and prevents them from being
returned from look-up.
Maintaining POSIX rename semantics
==================================
Since look-up of dentries is lock-free, it can race against a
concurrent rename operation. For example, during rename of file A to
B, look-up of either A or B must succeed. So, if look-up of B happens
after A has been removed from the hash chain but not added to the new
hash chain, it may fail. Also, a comparison while the name is being
written concurrently by a rename may result in false positive matches
violating rename semantics. Issues related to race with rename are
handled as described below :
1. Look-up can be done in two ways - d_lookup() which is safe from
simultaneous renames and __d_lookup() which is not. If
__d_lookup() fails, it must be followed up by a d_lookup() to
correctly determine whether a dentry is in the hash table or
not. d_lookup() protects look-ups using a sequence lock
(rename_lock).
2. The name associated with a dentry (d_name) may be changed if a
rename is allowed to happen simultaneously. To avoid memcmp() in
__d_lookup() go out of bounds due to a rename and false positive
comparison, the name comparison is done while holding the
per-dentry lock. This prevents concurrent renames during this
operation.
3. Hash table walking during look-up may move to a different bucket as
the current dentry is moved to a different bucket due to rename.
But we use hlists in dcache hash table and they are
null-terminated. So, even if a dentry moves to a different bucket,
hash chain walk will terminate. [with a list_head list, it may not
since termination is when the list_head in the original bucket is
reached]. Since we redo the d_parent check and compare name while
holding d_lock, lock-free look-up will not race against d_move().
4. There can be a theoretical race when a dentry keeps coming back to
original bucket due to double moves. Due to this look-up may
consider that it has never moved and can end up in a infinite loop.
But this is not any worse that theoretical livelocks we already
have in the kernel.
Important guidelines for filesystem developers related to dcache_rcu
====================================================================
1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
don't change. Only dcache internal implementation changes. However
filesystems *must not* delete from the dentry hash chains directly
using the list macros like allowed earlier. They must use dcache
APIs like d_drop() or __d_drop() depending on the situation.
2. d_flags is now protected by a per-dentry lock (d_lock). All access
to d_flags must be protected by it.
3. For a hashed dentry, checking of d_count needs to be protected by
d_lock.

ramfs, rootfs and initramfs
October 17, 2005
Rob Landley <rob@landley.net>
=============================
What is ramfs?
--------------
Ramfs is a very simple filesystem that exports Linux's disk caching
mechanisms (the page cache and dentry cache) as a dynamically resizable
ram-based filesystem.
Normally all files are cached in memory by Linux. Pages of data read from
backing store (usually the block device the filesystem is mounted on) are kept
around in case it's needed again, but marked as clean (freeable) in case the
Virtual Memory system needs the memory for something else. Similarly, data
written to files is marked clean as soon as it has been written to backing
store, but kept around for caching purposes until the VM reallocates the
memory. A similar mechanism (the dentry cache) greatly speeds up access to
directories.
With ramfs, there is no backing store. Files written into ramfs allocate
dentries and page cache as usual, but there's nowhere to write them to.
This means the pages are never marked clean, so they can't be freed by the
VM when it's looking to recycle memory.
The amount of code required to implement ramfs is tiny, because all the
work is done by the existing Linux caching infrastructure. Basically,
you're mounting the disk cache as a filesystem. Because of this, ramfs is not
an optional component removable via menuconfig, since there would be negligible
space savings.
ramfs and ramdisk:
------------------
The older "ram disk" mechanism created a synthetic block device out of
an area of ram and used it as backing store for a filesystem. This block
device was of fixed size, so the filesystem mounted on it was of fixed
size. Using a ram disk also required unnecessarily copying memory from the
fake block device into the page cache (and copying changes back out), as well
as creating and destroying dentries. Plus it needed a filesystem driver
(such as ext2) to format and interpret this data.
Compared to ramfs, this wastes memory (and memory bus bandwidth), creates
unnecessary work for the CPU, and pollutes the CPU caches. (There are tricks
to avoid this copying by playing with the page tables, but they're unpleasantly
complicated and turn out to be about as expensive as the copying anyway.)
More to the point, all the work ramfs is doing has to happen _anyway_,
since all file access goes through the page and dentry caches. The ram
disk is simply unnecessary, ramfs is internally much simpler.
Another reason ramdisks are semi-obsolete is that the introduction of
loopback devices offered a more flexible and convenient way to create
synthetic block devices, now from files instead of from chunks of memory.
See losetup (8) for details.
ramfs and tmpfs:
----------------
One downside of ramfs is you can keep writing data into it until you fill
up all memory, and the VM can't free it because the VM thinks that files
should get written to backing store (rather than swap space), but ramfs hasn't
got any backing store. Because of this, only root (or a trusted user) should
be allowed write access to a ramfs mount.
A ramfs derivative called tmpfs was created to add size limits, and the ability
to write the data to swap space. Normal users can be allowed write access to
tmpfs mounts. See Documentation/filesystems/tmpfs.txt for more information.
What is rootfs?
---------------
Rootfs is a special instance of ramfs, which is always present in 2.6 systems.
(It's used internally as the starting and stopping point for searches of the
kernel's doubly-linked list of mount points.)
Most systems just mount another filesystem over it and ignore it. The
amount of space an empty instance of ramfs takes up is tiny.
What is initramfs?
------------------
All 2.6 Linux kernels contain a gzipped "cpio" format archive, which is
extracted into rootfs when the kernel boots up. After extracting, the kernel
checks to see if rootfs contains a file "init", and if so it executes it as PID
1. If found, this init process is responsible for bringing the system the
rest of the way up, including locating and mounting the real root device (if
any). If rootfs does not contain an init program after the embedded cpio
archive is extracted into it, the kernel will fall through to the older code
to locate and mount a root partition, then exec some variant of /sbin/init
out of that.
All this differs from the old initrd in several ways:
- The old initrd was a separate file, while the initramfs archive is linked
into the linux kernel image. (The directory linux-*/usr is devoted to
generating this archive during the build.)
- The old initrd file was a gzipped filesystem image (in some file format,
such as ext2, that had to be built into the kernel), while the new
initramfs archive is a gzipped cpio archive (like tar only simpler,
see cpio(1) and Documentation/early-userspace/buffer-format.txt).
- The program run by the old initrd (which was called /initrd, not /init) did
some setup and then returned to the kernel, while the init program from
initramfs is not expected to return to the kernel. (If /init needs to hand
off control it can overmount / with a new root device and exec another init
program. See the switch_root utility, below.)
- When switching another root device, initrd would pivot_root and then
umount the ramdisk. But initramfs is rootfs: you can neither pivot_root
rootfs, nor unmount it. Instead delete everything out of rootfs to
free up the space (find -xdev / -exec rm '{}' ';'), overmount rootfs
with the new root (cd /newmount; mount --move . /; chroot .), attach
stdin/stdout/stderr to the new /dev/console, and exec the new init.
Since this is a remarkably persnickity process (and involves deleting
commands before you can run them), the klibc package introduced a helper
program (utils/run_init.c) to do all this for you. Most other packages
(such as busybox) have named this command "switch_root".
Populating initramfs:
---------------------
The 2.6 kernel build process always creates a gzipped cpio format initramfs
archive and links it into the resulting kernel binary. By default, this
archive is empty (consuming 134 bytes on x86). The config option
CONFIG_INITRAMFS_SOURCE (for some reason buried under devices->block devices
in menuconfig, and living in usr/Kconfig) can be used to specify a source for
the initramfs archive, which will automatically be incorporated into the
resulting binary. This option can point to an existing gzipped cpio archive, a
directory containing files to be archived, or a text file specification such
as the following example:
dir /dev 755 0 0
nod /dev/console 644 0 0 c 5 1
nod /dev/loop0 644 0 0 b 7 0
dir /bin 755 1000 1000
slink /bin/sh busybox 777 0 0
file /bin/busybox initramfs/busybox 755 0 0
dir /proc 755 0 0
dir /sys 755 0 0
dir /mnt 755 0 0
file /init initramfs/init.sh 755 0 0
One advantage of the text file is that root access is not required to
set permissions or create device nodes in the new archive. (Note that those
two example "file" entries expect to find files named "init.sh" and "busybox" in
a directory called "initramfs", under the linux-2.6.* directory. See
Documentation/early-userspace/README for more details.)
If you don't already understand what shared libraries, devices, and paths
you need to get a minimal root filesystem up and running, here are some
references:
http://www.tldp.org/HOWTO/Bootdisk-HOWTO/
http://www.tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html
http://www.linuxfromscratch.org/lfs/view/stable/
The "klibc" package (http://www.kernel.org/pub/linux/libs/klibc) is
designed to be a tiny C library to statically link early userspace
code against, along with some related utilities. It is BSD licensed.
I use uClibc (http://www.uclibc.org) and busybox (http://www.busybox.net)
myself. These are LGPL and GPL, respectively.
In theory you could use glibc, but that's not well suited for small embedded
uses like this. (A "hello world" program statically linked against glibc is
over 400k. With uClibc it's 7k. Also note that glibc dlopens libnss to do
name lookups, even when otherwise statically linked.)
Future directions:
------------------
Today (2.6.14), initramfs is always compiled in, but not always used. The
kernel falls back to legacy boot code that is reached only if initramfs does
not contain an /init program. The fallback is legacy code, there to ensure a
smooth transition and allowing early boot functionality to gradually move to
"early userspace" (I.E. initramfs).
The move to early userspace is necessary because finding and mounting the real
root device is complex. Root partitions can span multiple devices (raid or
separate journal). They can be out on the network (requiring dhcp, setting a
specific mac address, logging into a server, etc). They can live on removable
media, with dynamically allocated major/minor numbers and persistent naming
issues requiring a full udev implementation to sort out. They can be
compressed, encrypted, copy-on-write, loopback mounted, strangely partitioned,
and so on.
This kind of complexity (which inevitably includes policy) is rightly handled
in userspace. Both klibc and busybox/uClibc are working on simple initramfs
packages to drop into a kernel build, and when standard solutions are ready
and widely deployed, the kernel's legacy early boot code will become obsolete
and a candidate for the feature removal schedule.
But that's a while off yet.

Introduction
============
The Virtual File System (otherwise known as the Virtual Filesystem
Switch) is the software layer in the kernel that provides the
filesystem interface to userspace programs. It also provides an
abstraction within the kernel which allows different filesystem
implementations to coexist.
The Virtual File System (also known as the Virtual Filesystem Switch)
is the software layer in the kernel that provides the filesystem
interface to userspace programs. It also provides an abstraction
within the kernel which allows different filesystem implementations to
coexist.
VFS system calls open(2), stat(2), read(2), write(2), chmod(2) and so
on are called from a process context. Filesystem locking is described
in the document Documentation/filesystems/Locking.
A Quick Look At How It Works
============================
Directory Entry Cache (dcache)
------------------------------
In this section I'll briefly describe how things work, before
launching into the details. I'll start with describing what happens
when user programs open and manipulate files, and then look from the
other view which is how a filesystem is supported and subsequently
mounted.
The VFS implements the open(2), stat(2), chmod(2), and similar system
calls. The pathname argument that is passed to them is used by the VFS
to search through the directory entry cache (also known as the dentry
cache or dcache). This provides a very fast look-up mechanism to
translate a pathname (filename) into a specific dentry. Dentries live
in RAM and are never saved to disc: they exist only for performance.
The dentry cache is meant to be a view into your entire filespace. As
most computers cannot fit all dentries in the RAM at the same time,
some bits of the cache are missing. In order to resolve your pathname
into a dentry, the VFS may have to resort to creating dentries along
the way, and then loading the inode. This is done by looking up the
inode.
Opening a File
--------------
The Inode Object
----------------
The VFS implements the open(2), stat(2), chmod(2) and similar system
calls. The pathname argument is used by the VFS to search through the
directory entry cache (dentry cache or "dcache"). This provides a very
fast look-up mechanism to translate a pathname (filename) into a
specific dentry.
An individual dentry usually has a pointer to an inode. Inodes are
filesystem objects such as regular files, directories, FIFOs and other
beasts. They live either on the disc (for block device filesystems)
or in the memory (for pseudo filesystems). Inodes that live on the
disc are copied into the memory when required and changes to the inode
are written back to disc. A single inode can be pointed to by multiple
dentries (hard links, for example, do this).
An individual dentry usually has a pointer to an inode. Inodes are the
things that live on disc drives, and can be regular files (you know:
those things that you write data into), directories, FIFOs and other
beasts. Dentries live in RAM and are never saved to disc: they exist
only for performance. Inodes live on disc and are copied into memory
when required. Later any changes are written back to disc. The inode
that lives in RAM is a VFS inode, and it is this which the dentry
points to. A single inode can be pointed to by multiple dentries
(think about hardlinks).
To look up an inode requires that the VFS calls the lookup() method of
the parent directory inode. This method is installed by the specific
filesystem implementation that the inode lives in. Once the VFS has
the required dentry (and hence the inode), we can do all those boring
things like open(2) the file, or stat(2) it to peek at the inode
data. The stat(2) operation is fairly simple: once the VFS has the
dentry, it peeks at the inode data and passes some of it back to
userspace.
The dcache is meant to be a view into your entire filespace. Unlike
Linus, most of us losers can't fit enough dentries into RAM to cover
all of our filespace, so the dcache has bits missing. In order to
resolve your pathname into a dentry, the VFS may have to resort to
creating dentries along the way, and then loading the inode. This is
done by looking up the inode.
To look up an inode (usually read from disc) requires that the VFS

The File Object
---------------
Opening a file requires another operation: allocation of a file
structure (this is the kernel-side implementation of file
@ -74,51 +73,39 @@ descriptors). The freshly allocated file structure is initialized with
a pointer to the dentry and a set of file operation member functions.
These are taken from the inode data. The open() file method is then
called so the specific filesystem implementation can do it's work. You
can see that this is another switch performed by the VFS.
The file structure is placed into the file descriptor table for the
process.
can see that this is another switch performed by the VFS. The file
structure is placed into the file descriptor table for the process.
Reading, writing and closing files (and other assorted VFS operations)
is done by using the userspace file descriptor to grab the appropriate
file structure, and then calling the required file structure method
function to do whatever is required.
For as long as the file is open, it keeps the dentry "open" (in use),
which in turn means that the VFS inode is still in use.
All VFS system calls (i.e. open(2), stat(2), read(2), write(2),
chmod(2) and so on) are called from a process context. You should
assume that these calls are made without any kernel locks being
held. This means that the processes may be executing the same piece of
filesystem or driver code at the same time, on different
processors. You should ensure that access to shared resources is
protected by appropriate locks.

Registering and Mounting a Filesystem
-------------------------------------
=====================================
If you want to support a new kind of filesystem in the kernel, all you
need to do is call register_filesystem(). You pass a structure
describing the filesystem implementation (struct file_system_type)
which is then added to an internal table of supported filesystems. You
can do:
To register and unregister a filesystem, use the following API
functions:
% cat /proc/filesystems
#include <linux/fs.h>

RCU-based dcache locking model
------------------------------
On many workloads, the most common operation on dcache is
to look up a dentry, given a parent dentry and the name
of the child. Typically, for every open(), stat() etc.,
the dentry corresponding to the pathname will be looked
up by walking the tree starting with the first component
of the pathname and using that dentry along with the next
component to look up the next level and so on. Since it
is a frequent operation for workloads like multiuser
environments and web servers, it is important to optimize
this path.
Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus
in every component during path look-up. Since 2.5.10 onwards,
fast-walk algorithm changed this by holding the dcache_lock
at the beginning and walking as many cached path component
dentries as possible. This significantly decreases the number
of acquisition of dcache_lock. However it also increases the
lock hold time significantly and affects performance in large
SMP machines. Since 2.5.62 kernel, dcache has been using
a new locking model that uses RCU to make dcache look-up
lock-free.
The current dcache locking model is not very different from the existing
dcache locking model. Prior to 2.5.62 kernel, dcache_lock
protected the hash chain, d_child, d_alias, d_lru lists as well
as d_inode and several other things like mount look-up. RCU-based
changes affect only the way the hash chain is protected. For everything
else the dcache_lock must be taken for both traversing as well as
updating. The hash chain updates too take the dcache_lock.
The significant change is the way d_lookup traverses the hash chain,
it doesn't acquire the dcache_lock for this and rely on RCU to
ensure that the dentry has not been *freed*.
For further information on dentry locking, please refer to the document
Documentation/filesystems/dentry-locking.txt.
Dcache locking details
----------------------
Resources
=========
For many multi-user workloads, open() and stat() on files are
very frequently occurring operations. Both involve walking
of path names to find the dentry corresponding to the
concerned file. In 2.4 kernel, dcache_lock was held
during look-up of each path component. Contention and
cache-line bouncing of this global lock caused significant
scalability problems. With the introduction of RCU
in Linux kernel, this was worked around by making
the look-up of path components during path walking lock-free.
(Note some of these resources are not up-to-date with the latest kernel
version.)

Safe lock-free look-up of dcache hash table
===========================================
The Linux Virtual File-system Layer by Neil Brown. 1999
<http://www.cse.unsw.edu.au/~neilb/oss/linux-commentary/vfs.html>
Dcache is a complex data structure with the hash table entries
also linked together in other lists. In 2.4 kernel, dcache_lock
protected all the lists. We applied RCU only on hash chain
walking. The rest of the lists are still protected by dcache_lock.
Some of the important changes are :
A tour of the Linux VFS by Michael K. Johnson. 1996
<http://www.tldp.org/LDP/khg/HyperNews/get/fs/vfstour.html>
1. The deletion from hash chain is done using hlist_del_rcu() macro which
doesn't initialize next pointer of the deleted dentry and this
allows us to walk safely lock-free while a deletion is happening.
2. Insertion of a dentry into the hash table is done using
hlist_add_head_rcu() which take care of ordering the writes -
the writes to the dentry must be visible before the dentry
is inserted. This works in conjunction with hlist_for_each_rcu()
while walking the hash chain. The only requirement is that
all initialization to the dentry must be done before hlist_add_head_rcu()
since we don't have dcache_lock protection while traversing
the hash chain. This isn't different from the existing code.
3. The dentry looked up without holding dcache_lock by cannot be
returned for walking if it is unhashed. It then may have a NULL
d_inode or other bogosity since RCU doesn't protect the other
fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
indicate unhashed dentries and use this in conjunction with a
per-dentry lock (d_lock). Once looked up without the dcache_lock,
we acquire the per-dentry lock (d_lock) and check if the
dentry is unhashed. If so, the look-up is failed. If not, the
reference count of the dentry is increased and the dentry is returned.
4. Once a dentry is looked up, it must be ensured during the path
walk for that component it doesn't go away. In pre-2.5.10 code,
this was done holding a reference to the dentry. dcache_rcu does
the same. In some sense, dcache_rcu path walking looks like
the pre-2.5.10 version.
5. All dentry hash chain updates must take the dcache_lock as well as
the per-dentry lock in that order. dput() does this to ensure
that a dentry that has just been looked up in another CPU
doesn't get deleted before dget() can be done on it.
6. There are several ways to do reference counting of RCU protected
objects. One such example is in ipv4 route cache where
deferred freeing (using call_rcu()) is done as soon as
the reference count goes to zero. This cannot be done in
the case of dentries because tearing down of dentries
require blocking (dentry_iput()) which isn't supported from
RCU callbacks. Instead, tearing down of dentries happen
synchronously in dput(), but actual freeing happens later
when RCU grace period is over. This allows safe lock-free
walking of the hash chains, but a matched dentry may have
been partially torn down. The checking of DCACHE_UNHASHED
flag with d_lock held detects such dentries and prevents
them from being returned from look-up.
Maintaining POSIX rename semantics
==================================
Since look-up of dentries is lock-free, it can race against
a concurrent rename operation. For example, during rename
of file A to B, look-up of either A or B must succeed.
So, if look-up of B happens after A has been removed from the
hash chain but not added to the new hash chain, it may fail.
Also, a comparison while the name is being written concurrently
by a rename may result in false positive matches violating
rename semantics. Issues related to race with rename are
handled as described below :
1. Look-up can be done in two ways - d_lookup() which is safe
from simultaneous renames and __d_lookup() which is not.
If __d_lookup() fails, it must be followed up by a d_lookup()
to correctly determine whether a dentry is in the hash table
or not. d_lookup() protects look-ups using a sequence
lock (rename_lock).
2. The name associated with a dentry (d_name) may be changed if
a rename is allowed to happen simultaneously. To avoid memcmp()
in __d_lookup() go out of bounds due to a rename and false
positive comparison, the name comparison is done while holding the
per-dentry lock. This prevents concurrent renames during this
operation.
3. Hash table walking during look-up may move to a different bucket as
the current dentry is moved to a different bucket due to rename.
But we use hlists in dcache hash table and they are null-terminated.
So, even if a dentry moves to a different bucket, hash chain
walk will terminate. [with a list_head list, it may not since
termination is when the list_head in the original bucket is reached].
Since we redo the d_parent check and compare name while holding
d_lock, lock-free look-up will not race against d_move().
4. There can be a theoretical race when a dentry keeps coming back
to original bucket due to double moves. Due to this look-up may
consider that it has never moved and can end up in a infinite loop.
But this is not any worse that theoretical livelocks we already
have in the kernel.
Important guidelines for filesystem developers related to dcache_rcu
====================================================================
1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
don't change. Only dcache internal implementation changes. However
filesystems *must not* delete from the dentry hash chains directly
using the list macros like allowed earlier. They must use dcache
APIs like d_drop() or __d_drop() depending on the situation.
2. d_flags is now protected by a per-dentry lock (d_lock). All
access to d_flags must be protected by it.
3. For a hashed dentry, checking of d_count needs to be protected
by d_lock.

MD devices in sysfs
-------------------
md devices appear in sysfs (/sys) as regular block devices,
e.g.
/sys/block/md0
Each 'md' device will contain a subdirectory called 'md' which
contains further md-specific information about the device.
All md devices contain:
level
a text file indicating the 'raid level'. This may be a standard
numerical level prefixed by "RAID-" - e.g. "RAID-5", or some
other name such as "linear" or "multipath".
If no raid level has been set yet (array is still being
assembled), this file will be empty.
raid_disks
a text file with a simple number indicating the number of devices
in a fully functional array. If this is not yet known, the file
will be empty. If an array is being resized (not currently
possible) this will contain the larger of the old and new sizes.
As component devices are added to an md array, they appear in the 'md'
directory as new directories named
dev-XXX
where XXX is a name that the kernel knows for the device, e.g. hdb1.
Each directory contains:
block
a symlink to the block device in /sys/block, e.g.
/sys/block/md0/md/dev-hdb1/block -> ../../../../block/hdb/hdb1
super
A file containing an image of the superblock read from, or
written to, that device.
state
A file recording the current state of the device in the array
which can be a comma separated list of
faulty - device has been kicked from active use due to
a detected fault
in_sync - device is a fully in-sync member of the array
spare - device is working, but not a full member.
This includes spares that are in the process
of being recoverred to
This list make grow in future.
An active md device will also contain and entry for each active device
in the array. These are named
rdNN
where 'NN' is the possition in the array, starting from 0.
So for a 3 drive array there will be rd0, rd1, rd2.
These are symbolic links to the appropriate 'dev-XXX' entry.
Thus, for example,
cat /sys/block/md*/md/rd*/state
will show 'in_sync' on every line.
Active md devices for levels that support data redundancy (1,4,5,6)
also have
sync_action
a text file that can be used to monitor and control the rebuild
process. It contains one word which can be one of:
resync - redundancy is being recalculated after unclean
shutdown or creation
recover - a hot spare is being built to replace a
failed/missing device
idle - nothing is happening
check - A full check of redundancy was requested and is
happening. This reads all block and checks
them. A repair may also happen for some raid
levels.
repair - A full check and repair is happening. This is
similar to 'resync', but was requested by the
user, and the write-intent bitmap is NOT used to
optimise the process.
This file is writable, and each of the strings that could be
read are meaningful for writing.
'idle' will stop an active resync/recovery etc. There is no
guarantee that another resync/recovery may not be automatically
started again, though some event will be needed to trigger
this.
'resync' or 'recovery' can be used to restart the
corresponding operation if it was stopped with 'idle'.
'check' and 'repair' will start the appropriate process
providing the current state is 'idle'.
mismatch_count
When performing 'check' and 'repair', and possibly when
performing 'resync', md will count the number of errors that are
found. The count in 'mismatch_cnt' is the number of sectors
that were re-written, or (for 'check') would have been
re-written. As most raid levels work in units of pages rather
than sectors, this my be larger than the number of actual errors
by a factor of the number of sectors in a page.
Each active md device may also have attributes specific to the
personality module that manages it.
These are specific to the implementation of the module and could
change substantially if the implementation changes.
These currently include
stripe_cache_size (currently raid5 only)
number of entries in the stripe cache. This is writable, but
there are upper and lower limits (32768, 16). Default is 128.
strip_cache_active (currently raid5 only)

Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
Intel wireless LAN adapters are engineered, manufactured, tested, and
quality checked to ensure that they meet all necessary local and
governmental regulatory agency requirements for the regions that they
are designated and/or marked to ship into. Since wireless LANs are
generally unlicensed devices that share spectrum with radars,
satellites, and other licensed and unlicensed devices, it is sometimes
necessary to dynamically detect, avoid, and limit usage to avoid
interference with these devices. In many instances Intel is required to
provide test data to prove regional and local compliance to regional and
governmental regulations before certification or approval to use the
product is granted. Intel's wireless LAN's EEPROM, firmware, and
software driver are designed to carefully control parameters that affect
radio operation and to ensure electromagnetic compliance (EMC). These
parameters include, without limitation, RF power, spectrum usage,
channel scanning, and human exposure.
For these reasons Intel cannot permit any manipulation by third parties
of the software provided in binary format with the wireless WLAN
adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
patches, utilities, or code with the Intel wireless LAN adapters that
have been manipulated by an unauthorized party (i.e., patches,
utilities, or code (including open source code modifications) which have
not been validated by Intel), (i) you will be solely responsible for
ensuring the regulatory compliance of the products, (ii) Intel will bear
no liability, under any theory of liability for any issues associated
with the modified products, including without limitation, claims under
the warranty and/or issues arising from regulatory non-compliance, and
(iii) Intel will not provide or be required to assist in providing
support to any third parties for such modified products.
Note: Many regulatory agencies consider Wireless LAN adapters to be
modules, and accordingly, condition system-level regulatory approval
upon receipt and review of test data documenting that the antennas and
system configuration do not cause the EMC and radio operation to be
non-compliant.
The drivers available for download from SourceForge are provided as a
part of a development project. Conformance to local regulatory
requirements is the responsibility of the individual developer. As
such, if you are interested in deploying or shipping a driver as part of

-----------------------------------------------
Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
Intel wireless LAN adapters are engineered, manufactured, tested, and
quality checked to ensure that they meet all necessary local and
governmental regulatory agency requirements for the regions that they
are designated and/or marked to ship into. Since wireless LANs are
generally unlicensed devices that share spectrum with radars,
satellites, and other licensed and unlicensed devices, it is sometimes
necessary to dynamically detect, avoid, and limit usage to avoid
interference with these devices. In many instances Intel is required to
provide test data to prove regional and local compliance to regional and
governmental regulations before certification or approval to use the
product is granted. Intel's wireless LAN's EEPROM, firmware, and
software driver are designed to carefully control parameters that affect
radio operation and to ensure electromagnetic compliance (EMC). These
parameters include, without limitation, RF power, spectrum usage,
channel scanning, and human exposure.
For these reasons Intel cannot permit any manipulation by third parties
of the software provided in binary format with the wireless WLAN
adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
patches, utilities, or code with the Intel wireless LAN adapters that
have been manipulated by an unauthorized party (i.e., patches,
utilities, or code (including open source code modifications) which have
not been validated by Intel), (i) you will be solely responsible for
ensuring the regulatory compliance of the products, (ii) Intel will bear
no liability, under any theory of liability for any issues associated
with the modified products, including without limitation, claims under
the warranty and/or issues arising from regulatory non-compliance, and
(iii) Intel will not provide or be required to assist in providing
support to any third parties for such modified products.
Note: Many regulatory agencies consider Wireless LAN adapters to be
modules, and accordingly, condition system-level regulatory approval
upon receipt and review of test data documenting that the antennas and
system configuration do not cause the EMC and radio operation to be
non-compliant.
The drivers available for download from SourceForge are provided as a
part of a development project. Conformance to local regulatory
requirements is the responsibility of the individual developer. As
such, if you are interested in deploying or shipping a driver as part of
solution intended to be used for purposes other than development, please
obtain a tested driver from Intel Customer Support at:

DCCP protocol
============
Last updated: 10 November 2005
Contents

- Introduction

- Socket options
- Notes
Introduction
============
Datagram Congestion Control Protocol (DCCP) is an unreliable, connection
based protocol designed to solve issues present in UDP and TCP particularly
for real time and multimedia traffic.
It has a base protocol and pluggable congestion control IDs (CCIDs).
It is at draft RFC status and the homepage for DCCP as a protocol is at:
http://www.icir.org/kohler/dcp/
Missing features
================
The DCCP implementation does not currently have all the features that are in
the draft RFC.
In particular the following are missing:
- CCID2 support
- feature negotiation
When testing against other implementations it appears that elapsed time
options are not coded compliant to the specification.
Socket options
==============
DCCP_SOCKOPT_PACKET_SIZE is used for CCID3 to set default packet size for
calculations.
DCCP_SOCKOPT_SERVICE sets the service. This is compulsory as per the
specification. If you don't set it you will get EPROTO.
Notes
=====
SELinux does not yet have support for DCCP. You will need to turn it off or
else you will get EACCES.
DCCP does not travel through NAT successfully at present. This is because
the checksum covers the psuedo-header as per TCP and UDP. It should be
relatively trivial to add Linux NAT support for DCCP.

CPU Scheduler implementation hints for architecture specific code
Nick Piggin, 2005
Context switch
==============
1. Runqueue locking
By default, the switch_to arch function is called with the runqueue
locked. This is usually not a problem unless switch_to may need to
take the runqueue lock. This is usually due to a wake up operation in
the context switch. See include/asm-ia64/system.h for an example.
To request the scheduler call switch_to with the runqueue unlocked,
you must `#define __ARCH_WANT_UNLOCKED_CTXSW` in a header file
(typically the one where switch_to is defined).
Unlocked context switches introduce only a very minor performance
penalty to the core scheduler implementation in the CONFIG_SMP case.
2. Interrupt status
By default, the switch_to arch function is called with interrupts
disabled. Interrupts may be enabled over the call if it is likely to
introduce a significant interrupt latency by adding the line
`#define __ARCH_WANT_INTERRUPTS_ON_CTXSW` in the same place as for
unlocked context switches. This define also implies
`__ARCH_WANT_UNLOCKED_CTXSW`. See include/asm-arm/system.h for an
example.
CPU idle
========
Your cpu_idle routines need to obey the following rules:
1. Preempt should now disabled over idle routines. Should only
be enabled to call schedule() then disabled again.
2. need_resched/TIF_NEED_RESCHED is only ever set, and will never
be cleared until the running task has called schedule(). Idle
threads need only ever query need_resched, and may never set or
clear it.
3. When cpu_idle finds (need_resched() == 'true'), it should call
schedule(). It should not call schedule() otherwise.
4. The only time interrupts need to be disabled when checking
need_resched is if we are about to sleep the processor until
the next interrupt (this doesn't provide any protection of
need_resched, it prevents losing an interrupt).
4a. Common problem with this type of sleep appears to be:
local_irq_disable();
if (!need_resched()) {
local_irq_enable();
*** resched interrupt arrives here ***
__asm__("sleep until next interrupt");
}
5. TIF_POLLING_NRFLAG can be set by idle routines that do not
need an interrupt to wake them up when need_resched goes high.
In other words, they must be periodically polling need_resched,
although it may be reasonable to do some background work or enter
a low CPU priority.
5a. If TIF_POLLING_NRFLAG is set, and we do decide to enter
an interrupt sleep, it needs to be cleared then a memory
barrier issued (followed by a test of need_resched with
interrupts disabled, as explained in 3).
arch/i386/kernel/process.c has examples of both polling and
sleeping idle functions.
Possible arch/ problems
=======================
Possible arch problems I found (and either tried to fix or didn't):
h8300 - Is such sleeping racy vs interrupts? (See #4a).
The H8/300 manual I found indicates yes, however disabling IRQs
over the sleep mean only NMIs can wake it up, so can't fix easily
without doing spin waiting.
ia64 - is safe_halt call racy vs interrupts? (does it sleep?) (See #4a)
sh64 - Is sleeping racy vs interrupts? (See #4a)
sparc - IRQs on at this point(?), change local_irq_save to _disable.
- TODO: needs secondary CPUs to disable preempt (See #1)

INTRODUCTION
The USB Bluetooth driver supports any USB Bluetooth device.
It currently works well with the Linux USB Bluetooth stack from Axis
(available at http://developer.axis.com/software/bluetooth/ ) and
has been rumored to work with other Linux USB Bluetooth stacks.
CONFIGURATION
Currently the driver can handle up to 256 different USB Bluetooth
devices at once.
If you are not using devfs:
The major number that the driver uses is 216 so to use the driver,
create the following nodes:
mknod /dev/ttyUB0 c 216 0
mknod /dev/ttyUB1 c 216 1
mknod /dev/ttyUB2 c 216 2
mknod /dev/ttyUB3 c 216 3
.
.
.
mknod /dev/ttyUB254 c 216 254
mknod /dev/ttyUB255 c 216 255
If you are using devfs:
The devices supported by this driver will show up as
/dev/usb/ttub/{0,1,...}
When the device is connected and recognized by the driver, the driver
will print to the system log, which node the device has been bound to.
CONTACT:
If anyone has any problems using this driver, please contact me, or
join the Linux-USB mailing list (information on joining the mailing
list, as well as a link to its searchable archive is at
http://www.linux-usb.org/ )
