What: /sys/firmware/memmap/
Date: June 2008
Contact: Bernhard Walle <bwalle@suse.de>
Description:
On all platforms, the firmware provides a memory map which the
kernel reads. The resources from that memory map are registered
in the kernel resource tree and exposed to userspace via
/proc/iomem (together with other resources).
However, on most architectures that firmware-provided memory
map is modified afterwards by the kernel itself, either because
the kernel merges that memory map with other information or
just because the user overwrites that memory map via command
line.
kexec needs the raw firmware-provided memory map to setup the
parameter segment of the kernel that should be booted with
kexec. Also, the raw memory map is useful for debugging. For
that reason, /sys/firmware/memmap is an interface that provides
the raw memory map to userspace.
The structure is as follows: Under /sys/firmware/memmap there
are subdirectories with the number of the entry as their name:
/sys/firmware/memmap/0
/sys/firmware/memmap/1
/sys/firmware/memmap/2
/sys/firmware/memmap/3
...
The maximum depends on the number of memory map entries provided
by the firmware. The order is just the order that the firmware
provides.
Each directory contains three files:
start : The start address (as hexadecimal number with the
'0x' prefix).
end : The end address, inclusive (regardless whether the
firmware provides inclusive or exclusive ranges).
type : Type of the entry as string. See below for a list of
valid types.
So, for example:
/sys/firmware/memmap/0/start
/sys/firmware/memmap/0/end
/sys/firmware/memmap/0/type
/sys/firmware/memmap/1/start
...
Currently following types exist:
- System RAM
- ACPI Tables
- ACPI Non-volatile Storage
- reserved
Following shell snippet can be used to display that memory
map in a human-readable format:
-------------------- 8< ----------------------------------------
#!/bin/bash
cd /sys/firmware/memmap
for dir in * ; do
start=$(cat $dir/start)
end=$(cat $dir/end)
type=$(cat $dir/type)
printf "%016x-%016x (%s)\n" $start $[ $end +1] "$type"

SMP IRQ affinity, started by Ingo Molnar <mingo@redhat.com>
SMP IRQ affinity
/proc/irq/IRQ#/smp_affinity specifies which target CPUs are permitted
for a given IRQ source. It's a bitmask of allowed CPUs. It's not allowed
to turn off all CPUs, and if an IRQ controller does not support IRQ
affinity then the value will not change from the default 0xffffffff.
Here is an example of restricting IRQ44 (eth1) to CPU0-3 then restricting
the IRQ to CPU4-7 (this is an 8-CPU SMP box):
/proc/irq/default_smp_affinity specifies default affinity mask that applies
to all non-active IRQs. Once IRQ is allocated/activated its affinity bitmask
will be set to the default mask. It can then be changed as described above.
Default mask is 0xffffffff.

a. Make updates appear atomic to readers. For example,
a. Use the RCU variants of the list and hlist update

the readers refrain from accessing can be guarded by the
update-side lock.

pointer updates to properly aligned fields will appear
atomic, as will individual atomic primitives. Operations
performed under a lock and sequences of multiple atomic
primitives will -not- appear to be atomic.

restart the tests, regardless of the initial state specified by the

1. INTRODUCTION
Modern filesystems feature checksumming of data and metadata to
protect against data corruption. However, the detection of the
corruption is done at read time which could potentially be months
after the data was written. At that point the original data that the
application tried to write is most likely lost.
The solution is to ensure that the disk is actually storing what the
application meant it to. Recent additions to both the SCSI family
protocols (SBC Data Integrity Field, SCC protection proposal) as well
as SATA/T13 (External Path Protection) try to remedy this by adding
support for appending integrity metadata to an I/O. The integrity
metadata (or protection information in SCSI terminology) includes a
checksum for each sector as well as an incrementing counter that
ensures the individual sectors are written in the right order. And
for some protection schemes also that the I/O is written to the right
place on disk.
Current storage controllers and devices implement various protective
measures, for instance checksumming and scrubbing. But these
technologies are working in their own isolated domains or at best
between adjacent nodes in the I/O path. The interesting thing about
DIF and the other integrity extensions is that the protection format
is well defined and every node in the I/O path can verify the
integrity of the I/O and reject it if corruption is detected. This
allows not only corruption prevention but also isolation of the point
of failure.
----------------------------------------------------------------------
2. THE DATA INTEGRITY EXTENSIONS
As written, the protocol extensions only protect the path between
controller and storage device. However, many controllers actually
allow the operating system to interact with the integrity metadata
(IMD). We have been working with several FC/SAS HBA vendors to enable
the protection information to be transferred to and from their
controllers.
The SCSI Data Integrity Field works by appending 8 bytes of protection
information to each sector. The data + integrity metadata is stored
in 520 byte sectors on disk. Data + IMD are interleaved when
transferred between the controller and target. The T13 proposal is
similar.
Because it is highly inconvenient for operating systems to deal with
520 (and 4104) byte sectors, we approached several HBA vendors and
encouraged them to allow separation of the data and integrity metadata
scatter-gather lists.
The controller will interleave the buffers on write and split them on
read. This means that the Linux can DMA the data buffers to and from
host memory without changes to the page cache.
Also, the 16-bit CRC checksum mandated by both the SCSI and SATA specs
is somewhat heavy to compute in software. Benchmarks found that
calculating this checksum had a significant impact on system
performance for a number of workloads. Some controllers allow a
lighter-weight checksum to be used when interfacing with the operating
system. Emulex, for instance, supports the TCP/IP checksum instead.
The IP checksum received from the OS is converted to the 16-bit CRC
when writing and vice versa. This allows the integrity metadata to be
generated by Linux or the application at very low cost (comparable to
software RAID5).
The IP checksum is weaker than the CRC in terms of detecting bit
errors. However, the strength is really in the separation of the data
buffers and the integrity metadata. These two distinct buffers much
match up for an I/O to complete.
The separation of the data and integrity metadata buffers as well as
the choice in checksums is referred to as the Data Integrity
Extensions. As these extensions are outside the scope of the protocol
bodies (T10, T13), Oracle and its partners are trying to standardize
them within the Storage Networking Industry Association.
----------------------------------------------------------------------
3. KERNEL CHANGES
The data integrity framework in Linux enables protection information
to be pinned to I/Os and sent to/received from controllers that
support it.
The advantage to the integrity extensions in SCSI and SATA is that
they enable us to protect the entire path from application to storage
device. However, at the same time this is also the biggest
disadvantage. It means that the protection information must be in a
format that can be understood by the disk.
Generally Linux/POSIX applications are agnostic to the intricacies of
the storage devices they are accessing. The virtual filesystem switch
and the block layer make things like hardware sector size and
transport protocols completely transparent to the application.
However, this level of detail is required when preparing the
protection information to send to a disk. Consequently, the very
concept of an end-to-end protection scheme is a layering violation.
It is completely unreasonable for an application to be aware whether
it is accessing a SCSI or SATA disk.
The data integrity support implemented in Linux attempts to hide this
from the application. As far as the application (and to some extent
the kernel) is concerned, the integrity metadata is opaque information
that's attached to the I/O.
The current implementation allows the block layer to automatically
generate the protection information for any I/O. Eventually the
intent is to move the integrity metadata calculation to userspace for
user data. Metadata and other I/O that originates within the kernel
will still use the automatic generation interface.
Some storage devices allow each hardware sector to be tagged with a
16-bit value. The owner of this tag space is the owner of the block
device. I.e. the filesystem in most cases. The filesystem can use
this extra space to tag sectors as they see fit. Because the tag
space is limited, the block interface allows tagging bigger chunks by
way of interleaving. This way, 8*16 bits of information can be
attached to a typical 4KB filesystem block.
This also means that applications such as fsck and mkfs will need
access to manipulate the tags from user space. A passthrough
interface for this is being worked on.
----------------------------------------------------------------------
4. BLOCK LAYER IMPLEMENTATION DETAILS
4.1 BIO
The data integrity patches add a new field to struct bio when
CONFIG_BLK_DEV_INTEGRITY is enabled. bio->bi_integrity is a pointer
to a struct bip which contains the bio integrity payload. Essentially
a bip is a trimmed down struct bio which holds a bio_vec containing
the integrity metadata and the required housekeeping information (bvec
pool, vector count, etc.)
A kernel subsystem can enable data integrity protection on a bio by
calling bio_integrity_alloc(bio). This will allocate and attach the
bip to the bio.
Individual pages containing integrity metadata can subsequently be
attached using bio_integrity_add_page().
bio_free() will automatically free the bip.
4.2 BLOCK DEVICE
Because the format of the protection data is tied to the physical
disk, each block device has been extended with a block integrity
profile (struct blk_integrity). This optional profile is registered
with the block layer using blk_integrity_register().
The profile contains callback functions for generating and verifying
the protection data, as well as getting and setting application tags.
The profile also contains a few constants to aid in completing,
merging and splitting the integrity metadata.
Layered block devices will need to pick a profile that's appropriate
for all subdevices. blk_integrity_compare() can help with that. DM
and MD linear, RAID0 and RAID1 are currently supported. RAID4/5/6
will require extra work due to the application tag.
----------------------------------------------------------------------
5.0 BLOCK LAYER INTEGRITY API
5.1 NORMAL FILESYSTEM
The normal filesystem is unaware that the underlying block device
is capable of sending/receiving integrity metadata. The IMD will
be automatically generated by the block layer at submit_bio() time
in case of a WRITE. A READ request will cause the I/O integrity
to be verified upon completion.
IMD generation and verification can be toggled using the
/sys/block/<bdev>/integrity/write_generate
and
/sys/block/<bdev>/integrity/read_verify
flags.
5.2 INTEGRITY-AWARE FILESYSTEM
A filesystem that is integrity-aware can prepare I/Os with IMD
attached. It can also use the application tag space if this is
supported by the block device.
int bdev_integrity_enabled(block_device, int rw);
bdev_integrity_enabled() will return 1 if the block device
supports integrity metadata transfer for the data direction
specified in 'rw'.
bdev_integrity_enabled() honors the write_generate and
read_verify flags in sysfs and will respond accordingly.
int bio_integrity_prep(bio);
To generate IMD for WRITE and to set up buffers for READ, the
filesystem must call bio_integrity_prep(bio).
Prior to calling this function, the bio data direction and start
sector must be set, and the bio should have all data pages
added. It is up to the caller to ensure that the bio does not
change while I/O is in progress.
bio_integrity_prep() should only be called if
bio_integrity_enabled() returned 1.
int bio_integrity_tag_size(bio);
If the filesystem wants to use the application tag space it will
first have to find out how much storage space is available.
Because tag space is generally limited (usually 2 bytes per
sector regardless of sector size), the integrity framework
supports interleaving the information between the sectors in an
I/O.
Filesystems can call bio_integrity_tag_size(bio) to find out how
many bytes of storage are available for that particular bio.
Another option is bdev_get_tag_size(block_device) which will
return the number of available bytes per hardware sector.
int bio_integrity_set_tag(bio, void *tag_buf, len);
After a successful return from bio_integrity_prep(),
bio_integrity_set_tag() can be used to attach an opaque tag
buffer to a bio. Obviously this only makes sense if the I/O is
a WRITE.
int bio_integrity_get_tag(bio, void *tag_buf, len);
Similarly, at READ I/O completion time the filesystem can
retrieve the tag buffer using bio_integrity_get_tag().
6.3 PASSING EXISTING INTEGRITY METADATA
Filesystems that either generate their own integrity metadata or
are capable of transferring IMD from user space can use the
following calls:
struct bip * bio_integrity_alloc(bio, gfp_mask, nr_pages);
Allocates the bio integrity payload and hangs it off of the bio.
nr_pages indicate how many pages of protection data need to be
stored in the integrity bio_vec list (similar to bio_alloc()).
The integrity payload will be freed at bio_free() time.
int bio_integrity_add_page(bio, page, len, offset);
Attaches a page containing integrity metadata to an existing
bio. The bio must have an existing bip,
i.e. bio_integrity_alloc() must have been called. For a WRITE,
the integrity metadata in the pages must be in a format
understood by the target device with the notable exception that
the sector numbers will be remapped as the request traverses the
I/O stack. This implies that the pages added using this call
will be modified during I/O! The first reference tag in the
integrity metadata must have a value of bip->bip_sector.
Pages can be added using bio_integrity_add_page() as long as
there is room in the bip bio_vec array (nr_pages).
Upon completion of a READ operation, the attached pages will
contain the integrity metadata received from the storage device.
It is up to the receiver to process them and verify data
integrity upon completion.
6.4 REGISTERING A BLOCK DEVICE AS CAPABLE OF EXCHANGING INTEGRITY
METADATA
To enable integrity exchange on a block device the gendisk must be
registered as capable:
int blk_integrity_register(gendisk, blk_integrity);
The blk_integrity struct is a template and should contain the
following:
static struct blk_integrity my_profile = {
.name = "STANDARDSBODY-TYPE-VARIANT-CSUM",
.generate_fn = my_generate_fn,
.verify_fn = my_verify_fn,
.get_tag_fn = my_get_tag_fn,
.set_tag_fn = my_set_tag_fn,
.tuple_size = sizeof(struct my_tuple_size),
.tag_size = <tag bytes per hw sector>,
};
'name' is a text string which will be visible in sysfs. This is
part of the userland API so chose it carefully and never change
it. The format is standards body-type-variant.
E.g. T10-DIF-TYPE1-IP or T13-EPP-0-CRC.
'generate_fn' generates appropriate integrity metadata (for WRITE).
'verify_fn' verifies that the data buffer matches the integrity
metadata.
'tuple_size' must be set to match the size of the integrity
metadata per sector. I.e. 8 for DIF and EPP.
'tag_size' must be set to identify how many bytes of tag space
are available per hardware sector. For DIF this is either 2 or
0 depending on the value of the Control Mode Page ATO bit.
See 6.2 for a description of get_tag_fn and set_tag_fn.

===========================

- Compile and install the latest version of e2fsprogs (as of this
writing version 1.41) from:
http://sourceforge.net/project/showfiles.php?group_id=2406
or

- It's still mke2fs -j /dev/hda1
or grab the latest git repository from:
- mount /dev/hda1 /wherever -t ext4dev
git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
- To enable extents,
- Create a new filesystem using the ext4dev filesystem type:
mount /dev/hda1 /wherever -t ext4dev -o extents
# mke2fs -t ext4dev /dev/hda1
- The filesystem is compatible with the ext3 driver until you add a file
which has extents (ie: `mount -o extents', then create a file).
Or configure an existing ext3 filesystem to support extents and set
the test_fs flag to indicate that it's ok for an in-development
filesystem to touch this filesystem:
NOTE: The "extents" mount flag is temporary. It will soon go away and
extents will be enabled by the "-o extents" flag to mke2fs or tune2fs
# tune2fs -O extents -E test_fs /dev/hda1
If the filesystem was created with 128 byte inodes, it can be
converted to use 256 byte for greater efficiency via:
# tune2fs -I 256 /dev/hda1
(Note: we currently do not have tools to convert an ext4dev
filesystem back to ext3; so please do not do try this on production
filesystems.)
- Mounting:
# mount -t ext4dev /dev/hda1 /wherever
- When comparing performance with other filesystems, remember that
ext3/4 by default offers higher data integrity guarantees than most. So
when comparing with a metadata-only journalling filesystem, use `mount -o
data=writeback'. And you might as well use `mount -o nobh' too along
with it. Making the journal larger than the mke2fs default often helps
performance with metadata-intensive workloads.

2.2 Candidate features for future inclusion
There are several under discussion, whether they all make it in is
partly a function of how much time everyone has to work on them:
* Online defrag (patches available but not well tested)
* reduced mke2fs time via lazy itable initialization in conjuction with
the uninit_bg feature (capability to do this is available in e2fsprogs
but a kernel thread to do lazy zeroing of unused inode table blocks
after filesystem is first mounted is required for safety)
* improved file allocation (multi-block alloc, delayed alloc; basically done)
* fix 32000 subdirectory limit (patch exists, needs some e2fsck work)
* nsec timestamps for mtime, atime, ctime, create time (patch exists,
needs some e2fsck work)
* inode version field on disk (NFSv4, Lustre; prototype exists)

directly affect the on-disk format (outside of much better allocation)
so it isn't critical to get into the first round of changes. I believe

Glock internal locking rules
------------------------------
This documents the basic principles of the glock state machine
internals. Each glock (struct gfs2_glock in fs/gfs2/incore.h)
has two main (internal) locks:
1. A spinlock (gl_spin) which protects the internal state such
as gl_state, gl_target and the list of holders (gl_holders)
2. A non-blocking bit lock, GLF_LOCK, which is used to prevent other
threads from making calls to the DLM, etc. at the same time. If a
thread takes this lock, it must then call run_queue (usually via the
workqueue) when it releases it in order to ensure any pending tasks
are completed.
The gl_holders list contains all the queued lock requests (not
just the holders) associated with the glock. If there are any
held locks, then they will be contiguous entries at the head
of the list. Locks are granted in strictly the order that they
are queued, except for those marked LM_FLAG_PRIORITY which are
used only during recovery, and even then only for journal locks.
There are three lock states that users of the glock layer can request,
namely shared (SH), deferred (DF) and exclusive (EX). Those translate
to the following DLM lock modes:
Glock mode | DLM lock mode
------------------------------
UN | IV/NL Unlocked (no DLM lock associated with glock) or NL
SH | PR (Protected read)
DF | CW (Concurrent write)
EX | EX (Exclusive)
Thus DF is basically a shared mode which is incompatible with the "normal"
shared lock mode, SH. In GFS2 the DF mode is used exclusively for direct I/O
operations. The glocks are basically a lock plus some routines which deal
with cache management. The following rules apply for the cache:
Glock mode | Cache data | Cache Metadata | Dirty Data | Dirty Metadata
--------------------------------------------------------------------------
UN | No | No | No | No
SH | Yes | Yes | No | No
DF | No | Yes | No | No
EX | Yes | Yes | Yes | Yes
These rules are implemented using the various glock operations which
are defined for each type of glock. Not all types of glocks use
all the modes. Only inode glocks use the DF mode for example.
Table of glock operations and per type constants:
Field | Purpose
----------------------------------------------------------------------------
go_xmote_th | Called before remote state change (e.g. to sync dirty data)
go_xmote_bh | Called after remote state change (e.g. to refill cache)
go_inval | Called if remote state change requires invalidating the cache
go_demote_ok | Returns boolean value of whether its ok to demote a glock
| (e.g. checks timeout, and that there is no cached data)
go_lock | Called for the first local holder of a lock
go_unlock | Called on the final local unlock of a lock
go_dump | Called to print content of object for debugfs file, or on
| error to dump glock to the log.
go_type; | The type of the glock, LM_TYPE_.....
go_min_hold_time | The minimum hold time
The minimum hold time for each lock is the time after a remote lock
grant for which we ignore remote demote requests. This is in order to
prevent a situation where locks are being bounced around the cluster
from node to node with none of the nodes making any progress. This
tends to show up most with shared mmaped files which are being written
to by multiple nodes. By delaying the demotion in response to a
remote callback, that gives the userspace program time to make
some progress before the pages are unmapped.
There is a plan to try and remove the go_lock and go_unlock callbacks
if possible, in order to try and speed up the fast path though the locking.
Also, eventually we hope to make the glock "EX" mode locally shared
such that any local locking will be done with the i_mutex as required
rather than via the glock.
Locking rules for glock operations:
Operation | GLF_LOCK bit lock held | gl_spin spinlock held
-----------------------------------------------------------------
go_xmote_th | Yes | No
go_xmote_bh | Yes | No
go_inval | Yes | No
go_demote_ok | Sometimes | Yes
go_lock | Yes | No
go_unlock | Yes | No
go_dump | Sometimes | Yes
N.B. Operations must not drop either the bit lock or the spinlock
if its held on entry. go_dump and do_demote_ok must never block.
Note that go_dump will only be called if the glock's state
indicates that it is caching uptodate data.
Glock locking order within GFS2:
1. i_mutex (if required)
2. Rename glock (for rename only)
3. Inode glock(s)
(Parents before children, inodes at "same level" with same parent in
lock number order)
4. Rgrp glock(s) (for (de)allocation operations)
5. Transaction glock (via gfs2_trans_begin) for non-read operations
6. Page lock (always last, very important!)
There are two glocks per inode. One deals with access to the inode
itself (locking order as above), and the other, known as the iopen
glock is used in conjunction with the i_nlink field in the inode to
determine the lifetime of the inode in question. Locking of inodes
is on a per-inode basis. Locking of rgrps is on a per rgrp basis.

It could be used to set IRQ to CPU affinity, this means that you can "hook" an

irq subdir is one subdir for each IRQ, and two files; default_smp_affinity and

The contents of the prof_cpu_mask file and each smp_affinity file for each IRQ
is the same by default:
smp_affinity is a bitmask, in which you can specify which CPUs can handle the
IRQ, you can set it by doing:
> echo 1 > /proc/irq/10/smp_affinity
This means that only the first CPU will handle the IRQ, but you can also echo
5 which means that only the first and fourth CPU can handle the IRQ.
The contents of each smp_affinity file is the same by default:
> cat /proc/irq/0/smp_affinity
ffffffff
It's a bitmask, in which you can specify which CPUs can handle the IRQ, you can
set it by doing:
The default_smp_affinity mask applies to all non-active IRQs, which are the
IRQs which have not yet been allocated/activated, and hence which lack a
/proc/irq/[0-9]* directory.
> echo 1 > /proc/irq/prof_cpu_mask
This means that only the first CPU will handle the IRQ, but you can also echo 5
which means that only the first and fourth CPU can handle the IRQ.
prof_cpu_mask specifies which CPUs are to be profiled by the system wide
profiler. Default value is ffffffff (all cpus).

Description
-----------
WARNING: If you have an '810' or '815' motherboard, your standard I2C
temperature sensors are most likely on the 801's I2C bus. You want the
i2c-i801 driver for those, not this driver.
Now for the i2c-i810...
The GMCH chip contains two I2C interfaces.
The first interface is used for DDC (Data Display Channel) which is a
serial channel through the VGA monitor connector to a DDC-compliant
monitor. This interface is defined by the Video Electronics Standards
Association (VESA). The standards are available for purchase at
http://www.vesa.org .
The second interface is a general-purpose I2C bus. It may be connected to a
TV-out chip such as the BT869 or possibly to a digital flat-panel display.
Features
--------
Both busses use the i2c-algo-bit driver for 'bit banging'
and support for specific transactions is provided by i2c-algo-bit.
Issues
------
If you enable bus testing in i2c-algo-bit (insmod i2c-algo-bit bit_test=1),
the test may fail; if so, the i2c-i810 driver won't be inserted. However,
we think this has been fixed.

This is a summary of the most important conventions for use of fault
codes in the I2C/SMBus stack.
A "Fault" is not always an "Error"
----------------------------------
Not all fault reports imply errors; "page faults" should be a familiar
example. Software often retries idempotent operations after transient
faults. There may be fancier recovery schemes that are appropriate in
some cases, such as re-initializing (and maybe resetting). After such
recovery, triggered by a fault report, there is no error.
In a similar way, sometimes a "fault" code just reports one defined
result for an operation ... it doesn't indicate that anything is wrong
at all, just that the outcome wasn't on the "golden path".
In short, your I2C driver code may need to know these codes in order
to respond correctly. Other code may need to rely on YOUR code reporting
the right fault code, so that it can (in turn) behave correctly.
I2C and SMBus fault codes
-------------------------
These are returned as negative numbers from most calls, with zero or
some positive number indicating a non-fault return. The specific
numbers associated with these symbols differ between architectures,
though most Linux systems use <asm-generic/errno*.h> numbering.
Note that the descriptions here are not exhaustive. There are other
codes that may be returned, and other cases where these codes should
be returned. However, drivers should not return other codes for these
cases (unless the hardware doesn't provide unique fault reports).
Also, codes returned by adapter probe methods follow rules which are
specific to their host bus (such as PCI, or the platform bus).
EAGAIN
Returned by I2C adapters when they lose arbitration in master
transmit mode: some other master was transmitting different
data at the same time.
Also returned when trying to invoke an I2C operation in an
atomic context, when some task is already using that I2C bus
to execute some other operation.
EBADMSG
Returned by SMBus logic when an invalid Packet Error Code byte
is received. This code is a CRC covering all bytes in the
transaction, and is sent before the terminating STOP. This
fault is only reported on read transactions; the SMBus slave
may have a way to report PEC mismatches on writes from the
host. Note that even if PECs are in use, you should not rely
on these as the only way to detect incorrect data transfers.
EBUSY
Returned by SMBus adapters when the bus was busy for longer
than allowed. This usually indicates some device (maybe the
SMBus adapter) needs some fault recovery (such as resetting),
or that the reset was attempted but failed.
EINVAL
This rather vague error means an invalid parameter has been
detected before any I/O operation was started. Use a more
specific fault code when you can.
One example would be a driver trying an SMBus Block Write
with block size outside the range of 1-32 bytes.
EIO
This rather vague error means something went wrong when
performing an I/O operation. Use a more specific fault
code when you can.
ENODEV
Returned by driver probe() methods. This is a bit more
specific than ENXIO, implying the problem isn't with the
address, but with the device found there. Driver probes
may verify the device returns *correct* responses, and
return this as appropriate. (The driver core will warn
about probe faults other than ENXIO and ENODEV.)
ENOMEM
Returned by any component that can't allocate memory when
it needs to do so.
ENXIO
Returned by I2C adapters to indicate that the address phase
of a transfer didn't get an ACK. While it might just mean
an I2C device was temporarily not responding, usually it
means there's nothing listening at that address.
Returned by driver probe() methods to indicate that they
found no device to bind to. (ENODEV may also be used.)
EOPNOTSUPP
Returned by an adapter when asked to perform an operation
that it doesn't, or can't, support.
For example, this would be returned when an adapter that
doesn't support SMBus block transfers is asked to execute
one. In that case, the driver making that request should
have verified that functionality was supported before it
made that block transfer request.
Similarly, if an I2C adapter can't execute all legal I2C
messages, it should return this when asked to perform a
transaction it can't. (These limitations can't be seen in
the adapter's functionality mask, since the assumption is
that if an adapter supports I2C it supports all of I2C.)
EPROTO
Returned when slave does not conform to the relevant I2C
or SMBus (or chip-specific) protocol specifications. One
case is when the length of an SMBus block data response
(from the SMBus slave) is outside the range 1-32 bytes.
ETIMEDOUT
This is returned by drivers when an operation took too much
time, and was aborted before it completed.
SMBus adapters may return it when an operation took more
time than allowed by the SMBus specification; for example,
when a slave stretches clocks too far. I2C has no such
timeouts, but it's normal for I2C adapters to impose some
arbitrary limits (much longer than SMBus!) too.

Device Detection (Standard driver model)
----------------------------------------
Sometimes you do not know in advance which I2C devices are connected to
a given I2C bus. This is for example the case of hardware monitoring
devices on a PC's SMBus. In that case, you may want to let your driver
detect supported devices automatically. This is how the legacy model
was working, and is now available as an extension to the standard
driver model (so that we can finally get rid of the legacy model.)
You simply have to define a detect callback which will attempt to
identify supported devices (returning 0 for supported ones and -ENODEV
for unsupported ones), a list of addresses to probe, and a device type
(or class) so that only I2C buses which may have that type of device
connected (and not otherwise enumerated) will be probed. The i2c
core will then call you back as needed and will instantiate a device
for you for every successful detection.
Note that this mechanism is purely optional and not suitable for all
devices. You need some reliable way to identify the supported devices
(typically using device-specific, dedicated identification registers),
otherwise misdetections are likely to occur and things can get wrong
quickly.

attempt deciding that the remote end is unreachable. If this value
is exceeded, the association is terminated.
Default: 10
max_init_retransmits - INTEGER
The maximum number of retransmissions of INIT and COOKIE-ECHO chunks
that an association will attempt before declaring the destination
unreachable and terminating.
Default: 8
path_max_retrans - INTEGER
The maximum number of retransmissions that will be attempted on a given
path. Once this threshold is exceeded, the path is considered
unreachable, and new traffic will use a different path when the
association is multihomed.
Default: 5
rto_initial - INTEGER
The initial round trip timeout value in milliseconds that will be used
in calculating round trip times. This is the initial time interval
for retransmissions.
Default: 3000
rto_max - INTEGER
The maximum value (in milliseconds) of the round trip timeout. This
is the largest time interval that can elapse between retransmissions.
Default: 60000
rto_min - INTEGER
The minimum value (in milliseconds) of the round trip timeout. This
is the smallest time interval the can elapse between retransmissions.
Default: 1000
hb_interval - INTEGER
The interval (in milliseconds) between HEARTBEAT chunks. These chunks
are sent at the specified interval on idle paths to probe the state of
a given path between 2 associations.
Default: 30000
sack_timeout - INTEGER
The amount of time (in milliseconds) that the implementation will wait
to send a SACK.
Default: 200
valid_cookie_life - INTEGER
The default lifetime of the SCTP cookie (in milliseconds). The cookie
is used during association establishment.
Default: 60000
cookie_preserve_enable - BOOLEAN
Enable or disable the ability to extend the lifetime of the SCTP cookie
that is used during the establishment phase of SCTP association
1: Enable cookie lifetime extension.
0: Disable
Default: 1
rcvbuf_policy - INTEGER
Determines if the receive buffer is attributed to the socket or to
association. SCTP supports the capability to create multiple
associations on a single socket. When using this capability, it is
possible that a single stalled association that's buffering a lot
of data may block other associations from delivering their data by
consuming all of the receive buffer space. To work around this,
the rcvbuf_policy could be set to attribute the receiver buffer space
to each association instead of the socket. This prevents the described
blocking.
1: rcvbuf space is per association
0: recbuf space is per socket
Default: 0
sndbuf_policy - INTEGER
Similar to rcvbuf_policy above, this applies to send buffer space.
1: Send buffer is tracked per association
0: Send buffer is tracked per socket.
Default: 0
sctp_mem - vector of 3 INTEGERs: min, pressure, max
Number of pages allowed for queueing by all SCTP sockets.
min: Below this number of pages SCTP is not bothered about its
memory appetite. When amount of memory allocated by SCTP exceeds
this number, SCTP starts to moderate memory usage.
pressure: This value was introduced to follow format of tcp_mem.
max: Number of pages allowed for queueing by all SCTP sockets.
Default is calculated at boot time from amount of available memory.
sctp_rmem - vector of 3 INTEGERs: min, default, max
See tcp_rmem for a description.
sctp_wmem - vector of 3 INTEGERs: min, default, max
See tcp_wmem for a description.

In-kernel memory-mapped I/O tracing
Home page and links to optional user space tools:
http://nouveau.freedesktop.org/wiki/MmioTrace
MMIO tracing was originally developed by Intel around 2003 for their Fault
Injection Test Harness. In Dec 2006 - Jan 2007, using the code from Intel,
Jeff Muizelaar created a tool for tracing MMIO accesses with the Nouveau
project in mind. Since then many people have contributed.
Mmiotrace was built for reverse engineering any memory-mapped IO device with
the Nouveau project as the first real user. Only x86 and x86_64 architectures
are supported.
Out-of-tree mmiotrace was originally modified for mainline inclusion and
ftrace framework by Pekka Paalanen <pq@iki.fi>.
Preparation
-----------
Mmiotrace feature is compiled in by the CONFIG_MMIOTRACE option. Tracing is
disabled by default, so it is safe to have this set to yes. SMP systems are
supported, but tracing is unreliable and may miss events if more than one CPU
is on-line, therefore mmiotrace takes all but one CPU off-line during run-time
activation. You can re-enable CPUs by hand, but you have been warned, there
is no way to automatically detect if you are losing events due to CPUs racing.
Usage Quick Reference
---------------------
$ mount -t debugfs debugfs /debug
$ echo mmiotrace > /debug/tracing/current_tracer
$ cat /debug/tracing/trace_pipe > mydump.txt &
Start X or whatever.
$ echo "X is up" > /debug/tracing/marker
$ echo none > /debug/tracing/current_tracer
Check for lost events.
Usage
-----
Make sure debugfs is mounted to /debug. If not, (requires root privileges)
$ mount -t debugfs debugfs /debug
Check that the driver you are about to trace is not loaded.
Activate mmiotrace (requires root privileges):
$ echo mmiotrace > /debug/tracing/current_tracer
Start storing the trace:
$ cat /debug/tracing/trace_pipe > mydump.txt &
The 'cat' process should stay running (sleeping) in the background.
Load the driver you want to trace and use it. Mmiotrace will only catch MMIO
accesses to areas that are ioremapped while mmiotrace is active.
[Unimplemented feature:]
During tracing you can place comments (markers) into the trace by
$ echo "X is up" > /debug/tracing/marker
This makes it easier to see which part of the (huge) trace corresponds to
which action. It is recommended to place descriptive markers about what you
do.
Shut down mmiotrace (requires root privileges):
$ echo none > /debug/tracing/current_tracer
The 'cat' process exits. If it does not, kill it by issuing 'fg' command and
pressing ctrl+c.
Check that mmiotrace did not lose events due to a buffer filling up. Either
$ grep -i lost mydump.txt
which tells you exactly how many events were lost, or use
$ dmesg
to view your kernel log and look for "mmiotrace has lost events" warning. If
events were lost, the trace is incomplete. You should enlarge the buffers and
try again. Buffers are enlarged by first seeing how large the current buffers
are:
$ cat /debug/tracing/trace_entries
gives you a number. Approximately double this number and write it back, for
instance:
$ echo 128000 > /debug/tracing/trace_entries
Then start again from the top.
If you are doing a trace for a driver project, e.g. Nouveau, you should also
do the following before sending your results:
$ lspci -vvv > lspci.txt
$ dmesg > dmesg.txt
$ tar zcf pciid-nick-mmiotrace.tar.gz mydump.txt lspci.txt dmesg.txt
and then send the .tar.gz file. The trace compresses considerably. Replace
"pciid" and "nick" with the PCI ID or model name of your piece of hardware
under investigation and your nick name.
How Mmiotrace Works
-------------------
Access to hardware IO-memory is gained by mapping addresses from PCI bus by
calling one of the ioremap_*() functions. Mmiotrace is hooked into the
__ioremap() function and gets called whenever a mapping is created. Mapping is
an event that is recorded into the trace log. Note, that ISA range mappings
are not caught, since the mapping always exists and is returned directly.
MMIO accesses are recorded via page faults. Just before __ioremap() returns,
the mapped pages are marked as not present. Any access to the pages causes a
fault. The page fault handler calls mmiotrace to handle the fault. Mmiotrace
marks the page present, sets TF flag to achieve single stepping and exits the
fault handler. The instruction that faulted is executed and debug trap is
entered. Here mmiotrace again marks the page as not present. The instruction
is decoded to get the type of operation (read/write), data width and the value
read or written. These are stored to the trace log.
Setting the page present in the page fault handler has a race condition on SMP
machines. During the single stepping other CPUs may run freely on that page
and events can be missed without a notice. Re-enabling other CPUs during
tracing is discouraged.
Trace Log Format
----------------
The raw log is text and easily filtered with e.g. grep and awk. One record is
one line in the log. A record starts with a keyword, followed by keyword
dependant arguments. Arguments are separated by a space, or continue until the
end of line. The format for version 20070824 is as follows:
Explanation Keyword Space separated arguments
---------------------------------------------------------------------------
read event R width, timestamp, map id, physical, value, PC, PID
write event W width, timestamp, map id, physical, value, PC, PID
ioremap event MAP timestamp, map id, physical, virtual, length, PC, PID
iounmap event UNMAP timestamp, map id, PC, PID
marker MARK timestamp, text
version VERSION the string "20070824"
info for reader LSPCI one line from lspci -v
PCI address map PCIDEV space separated /proc/bus/pci/devices data
unk. opcode UNKNOWN timestamp, map id, physical, data, PC, PID
Timestamp is in seconds with decimals. Physical is a PCI bus address, virtual
is a kernel virtual address. Width is the data width in bytes and value is the
data value. Map id is an arbitrary id number identifying the mapping that was
used in an operation. PC is the program counter and PID is process id. PC is
zero if it is not recorded. PID is always zero as tracing MMIO accesses
originating in user space memory is not yet supported.
For instance, the following awk filter will pass all 32-bit writes that target
physical addresses in the range [0xfb73ce40, 0xfb800000[
$ awk '/W 4 / { adr=strtonum($5); if (adr >= 0xfb73ce40 &&
adr < 0xfb800000) print; }'
Tools for Developers
--------------------
The user space tools include utilities for:
- replacing numeric addresses and values with hardware register names
- replaying MMIO logs, i.e., re-executing the recorded writes

Select this option if you want to disable continuous timer ticks
and have them programmed to occur as required. This option saves
power as the system can remain in idle state for longer.
By default dynamic tick is disabled during the boot, and can be
manually enabled with:
echo 1 > /sys/devices/system/timer/timer0/dyn_tick
Alternatively, if you want dynamic tick automatically enabled
during boot, pass "dyntick=enable" via the kernel command string.
Please note that dynamic tick may affect the accuracy of
timekeeping on some platforms depending on the implementation.
Currently at least OMAP, PXA2xx and SA11x0 platforms are known
to have accurate timekeeping with dynamic tick.
