iii. Plugging the queue to batch requests in anticipation of opportunities for
merge/sort optimizations
This is just the same as in 2.4 so far, though per-device unplugging
support is anticipated for 2.5. Also with a priority-based i/o scheduler,
such decisions could be based on request priorities.
Plugging is an approach that the current i/o scheduling algorithm resorts to so
that it collects up enough requests in the queue to be able to take
advantage of the sorting/merging logic in the elevator. If the
queue is empty when a request comes in, then it plugs the request queue
(sort of like plugging the bottom of a vessel to get fluid to build up)
(sort of like plugging the bath tub of a vessel to get fluid to build up)
till it fills up with a few more requests, before starting to service
the requests. This provides an opportunity to merge/sort the requests before
passing them down to the device. There are various conditions when the queue is
unplugged (to open up the flow again), either through a scheduled task or
could be on demand. For example wait_on_buffer sets the unplugging going

the queue gets explicitly unplugged as part of waiting for completion,
in fact all queues get unplugged as a side-effect.

can do it explicity through blk_unplug(bdev). So in the read case,
the queue gets explicitly unplugged as part of waiting for completion on that

doing the blk_run_address_space().

be probed later if another device registers. (Which is OK, since
this interface is only for use with non-hotpluggable devices.)
Early Platform Devices and Drivers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The early platform interfaces provide platform data to platform device
drivers early on during the system boot. The code is built on top of the
early_param() command line parsing and can be executed very early on.
Example: "earlyprintk" class early serial console in 6 steps
1. Registering early platform device data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code registers platform device data using the function
early_platform_add_devices(). In the case of early serial console this
should be hardware configuration for the serial port. Devices registered
at this point will later on be matched against early platform drivers.
2. Parsing kernel command line
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code calls parse_early_param() to parse the kernel
command line. This will execute all matching early_param() callbacks.
User specified early platform devices will be registered at this point.
For the early serial console case the user can specify port on the
kernel command line as "earlyprintk=serial.0" where "earlyprintk" is
the class string, "serial" is the name of the platfrom driver and
0 is the platform device id. If the id is -1 then the dot and the
id can be omitted.
3. Installing early platform drivers belonging to a certain class
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code may optionally force registration of all early
platform drivers belonging to a certain class using the function
early_platform_driver_register_all(). User specified devices from
step 2 have priority over these. This step is omitted by the serial
driver example since the early serial driver code should be disabled
unless the user has specified port on the kernel command line.
4. Early platform driver registration
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Compiled-in platform drivers making use of early_platform_init() are
automatically registered during step 2 or 3. The serial driver example
should use early_platform_init("earlyprintk", &platform_driver).
5. Probing of early platform drivers belonging to a certain class
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The architecture code calls early_platform_driver_probe() to match
registered early platform devices associated with a certain class with
registered early platform drivers. Matched devices will get probed().
This step can be executed at any point during the early boot. As soon
as possible may be good for the serial port case.
6. Inside the early platform driver probe()
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The driver code needs to take special care during early boot, especially
when it comes to memory allocation and interrupt registration. The code
in the probe() function can use is_early_platform_device() to check if
it is called at early platform device or at the regular platform device
time. The early serial driver performs register_console() at this point.

Datagram vs Connected modes
The IPoIB driver supports two modes of operation: datagram and
connected. The mode is set and read through an interface's
/sys/class/net/<intf name>/mode file.
In datagram mode, the IB UD (Unreliable Datagram) transport is used
and so the interface MTU has is equal to the IB L2 MTU minus the
IPoIB encapsulation header (4 bytes). For example, in a typical IB
fabric with a 2K MTU, the IPoIB MTU will be 2048 - 4 = 2044 bytes.
In connected mode, the IB RC (Reliable Connected) transport is used.
Connected mode is to takes advantage of the connected nature of the
IB transport and allows an MTU up to the maximal IP packet size of
64K, which reduces the number of IP packets needed for handling
large UDP datagrams, TCP segments, etc and increases the performance
for large messages.
In connected mode, the interface's UD QP is still used for multicast
and communication with peers that don't support connected mode. In
this case, RX emulation of ICMP PMTU packets is used to cause the
networking stack to use the smaller UD MTU for these neighbours.
Stateless offloads
If the IB HW supports IPoIB stateless offloads, IPoIB advertises
TCP/IP checksum and/or Large Send (LSO) offloading capability to the
network stack.
Large Receive (LRO) offloading is also implemented and may be turned
on/off using ethtool calls. Currently LRO is supported only for
checksum offload capable devices.
Stateless offloads are supported only in datagram mode.
Interrupt moderation
If the underlying IB device supports CQ event moderation, one can
use ethtool to set interrupt mitigation parameters and thus reduce
the overhead incurred by handling interrupts. The main code path of
IPoIB doesn't use events for TX completion signaling so only RX
moderation is supported.

This driver adds support for the multi-touch trackpad on the new Apple
Macbook Air and Macbook Pro laptops. It replaces the appletouch driver on
those computers, and integrates well with the synaptics driver of the Xorg
system.
Known to work on Macbook Air, Macbook Pro Penryn and the new unibody
Macbook 5 and Macbook Pro 5.
Usage
-----
The driver loads automatically for the supported usb device ids, and
becomes available both as an event device (/dev/input/event*) and as a
mouse via the mousedev driver (/dev/input/mice).
USB Race
--------
The Apple multi-touch trackpads report both mouse and keyboard events via
different interfaces of the same usb device. This creates a race condition
with the HID driver, which, if not told otherwise, will find the standard
HID mouse and keyboard, and claim the whole device. To remedy, the usb
product id must be listed in the mouse_ignore list of the hid driver.
Debug output
------------
To ease the development for new hardware version, verbose packet output can
be switched on with the debug kernel module parameter. The range [1-9]
yields different levels of verbosity. Example (as root):
echo -n 9 > /sys/module/bcm5974/parameters/debug
tail -f /var/log/debug
echo -n 0 > /sys/module/bcm5974/parameters/debug

Multi-touch (MT) Protocol
-------------------------
Copyright (C) 2009 Henrik Rydberg <rydberg@euromail.se>
Introduction
------------
In order to utilize the full power of the new multi-touch devices, a way to
report detailed finger data to user space is needed. This document
describes the multi-touch (MT) protocol which allows kernel drivers to
report details for an arbitrary number of fingers.
Usage
-----
Anonymous finger details are sent sequentially as separate packets of ABS
events. Only the ABS_MT events are recognized as part of a finger
packet. The end of a packet is marked by calling the input_mt_sync()
function, which generates a SYN_MT_REPORT event. The end of multi-touch
transfer is marked by calling the usual input_sync() function.
A set of ABS_MT events with the desired properties is defined. The events
are divided into categories, to allow for partial implementation. The
minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and
ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the
device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size
of the approaching finger. Anisotropy and direction may be specified with
ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with
more granular information may specify general shapes as blobs, i.e., as a
sequence of rectangular shapes grouped together by an
ABS_MT_BLOB_ID. Finally, the ABS_MT_TOOL_TYPE may be used to specify
whether the touching tool is a finger or a pen or something else.
Event Semantics
---------------
The word "contact" is used to describe a tool which is in direct contact
with the surface. A finger, a pen or a rubber all classify as contacts.
ABS_MT_TOUCH_MAJOR
The length of the major axis of the contact. The length should be given in
surface units. If the surface has an X times Y resolution, the largest
possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal.
ABS_MT_TOUCH_MINOR
The length, in surface units, of the minor axis of the contact. If the
contact is circular, this event can be omitted.
ABS_MT_WIDTH_MAJOR
The length, in surface units, of the major axis of the approaching
tool. This should be understood as the size of the tool itself. The
orientation of the contact and the approaching tool are assumed to be the
same.
ABS_MT_WIDTH_MINOR
The length, in surface units, of the minor axis of the approaching
tool. Omit if circular.
The above four values can be used to derive additional information about
the contact. The ratio ABS_MT_TOUCH_MAJOR / ABS_MT_WIDTH_MAJOR approximates
the notion of pressure. The fingers of the hand and the palm all have
different characteristic widths [1].
ABS_MT_ORIENTATION
The orientation of the ellipse. The value should describe half a revolution
clockwise around the touch center. The scale of the value is arbitrary, but
zero should be returned for an ellipse aligned along the Y axis of the
surface. As an example, an index finger placed straight onto the axis could
return zero orientation, something negative when twisted to the left, and
something positive when twisted to the right. This value can be omitted if
the touching object is circular, or if the information is not available in
the kernel driver.
ABS_MT_POSITION_X
The surface X coordinate of the center of the touching ellipse.
ABS_MT_POSITION_Y
The surface Y coordinate of the center of the touching ellipse.
ABS_MT_TOOL_TYPE
The type of approaching tool. A lot of kernel drivers cannot distinguish
between different tool types, such as a finger or a pen. In such cases, the
event should be omitted. The protocol currently supports MT_TOOL_FINGER and
MT_TOOL_PEN [2].
ABS_MT_BLOB_ID
The BLOB_ID groups several packets together into one arbitrarily shaped
contact. This is a low-level anonymous grouping, and should not be confused
with the high-level contactID, explained below. Most kernel drivers will
not have this capability, and can safely omit the event.
Finger Tracking
---------------
The kernel driver should generate an arbitrary enumeration of the set of
anonymous contacts currently on the surface. The order in which the packets
appear in the event stream is not important.
The process of finger tracking, i.e., to assign a unique contactID to each
initiated contact on the surface, is left to user space; preferably the
multi-touch X driver [3]. In that driver, the contactID stays the same and
unique until the contact vanishes (when the finger leaves the surface). The
problem of assigning a set of anonymous fingers to a set of identified
fingers is a euclidian bipartite matching problem at each event update, and
relies on a sufficiently rapid update rate.
Notes
-----
In order to stay compatible with existing applications, the data
reported in a finger packet must not be recognized as single-touch
events. In addition, all finger data must bypass input filtering,
since subsequent events of the same type refer to different fingers.
The first kernel driver to utilize the MT protocol is the bcm5974 driver,
where examples can be found.
[1] With the extension ABS_MT_APPROACH_X and ABS_MT_APPROACH_Y, the
difference between the contact position and the approaching tool position
could be used to derive tilt.
[2] The list can of course be extended.
[3] The multi-touch X driver is currently in the prototyping stage. At the
time of writing (April 2009), the MT protocol is not yet merged, and the
prototype implements finger matching, basic mouse support and two-finger
scrolling. The project aims at improving the quality of current multi-touch
functionality available in the synaptics X driver, and in addition
implement more advanced gestures.

rotary-encoder - a generic driver for GPIO connected devices
Daniel Mack <daniel@caiaq.de>, Feb 2009
0. Function
-----------
Rotary encoders are devices which are connected to the CPU or other
peripherals with two wires. The outputs are phase-shifted by 90 degrees
and by triggering on falling and rising edges, the turn direction can
be determined.
The phase diagram of these two outputs look like this:
_____ _____ _____
| | | | | |
Channel A ____| |_____| |_____| |____
: : : : : : : : : : : :
__ _____ _____ _____
| | | | | | |

|<-------->|
one step
For more information, please see
http://en.wikipedia.org/wiki/Rotary_encoder
1. Events / state machine
-------------------------
a) Rising edge on channel A, channel B in low state
This state is used to recognize a clockwise turn
b) Rising edge on channel B, channel A in high state
When entering this state, the encoder is put into 'armed' state,
meaning that there it has seen half the way of a one-step transition.
c) Falling edge on channel A, channel B in high state
This state is used to recognize a counter-clockwise turn
d) Falling edge on channel B, channel A in low state
Parking position. If the encoder enters this state, a full transition
should have happend, unless it flipped back on half the way. The
'armed' state tells us about that.
2. Platform requirements
------------------------
As there is no hardware dependent call in this driver, the platform it is
used with must support gpiolib. Another requirement is that IRQs must be
able to fire on both edges.
3. Board integration
--------------------
To use this driver in your system, register a platform_device with the
name 'rotary-encoder' and associate the IRQs and some specific platform
data with it.
struct rotary_encoder_platform_data is declared in
include/linux/rotary-encoder.h and needs to be filled with the number of
steps the encoder has and can carry information about externally inverted
signals (because of used invertig buffer or other reasons).
Because GPIO to IRQ mapping is platform specific, this information must
be given in seperately to the driver. See the example below.

Kernel CAPI Interface to Hardware Drivers
-----------------------------------------
1. Overview
From the CAPI 2.0 specification:
COMMON-ISDN-API (CAPI) is an application programming interface standard used
to access ISDN equipment connected to basic rate interfaces (BRI) and primary
rate interfaces (PRI).
Kernel CAPI operates as a dispatching layer between CAPI applications and CAPI
hardware drivers. Hardware drivers register ISDN devices (controllers, in CAPI
lingo) with Kernel CAPI to indicate their readiness to provide their service
to CAPI applications. CAPI applications also register with Kernel CAPI,
requesting association with a CAPI device. Kernel CAPI then dispatches the
application registration to an available device, forwarding it to the
corresponding hardware driver. Kernel CAPI then forwards CAPI messages in both
directions between the application and the hardware driver.
Format and semantics of CAPI messages are specified in the CAPI 2.0 standard.
This standard is freely available from http://www.capi.org.
2. Driver and Device Registration
CAPI drivers optionally register themselves with Kernel CAPI by calling the
Kernel CAPI function register_capi_driver() with a pointer to a struct
capi_driver. This structure must be filled with the name and revision of the
driver, and optionally a pointer to a callback function, add_card(). The
registration can be revoked by calling the function unregister_capi_driver()
with a pointer to the same struct capi_driver.
CAPI drivers must register each of the ISDN devices they control with Kernel
CAPI by calling the Kernel CAPI function attach_capi_ctr() with a pointer to a
struct capi_ctr before they can be used. This structure must be filled with
the names of the driver and controller, and a number of callback function
pointers which are subsequently used by Kernel CAPI for communicating with the
driver. The registration can be revoked by calling the function
detach_capi_ctr() with a pointer to the same struct capi_ctr.
Before the device can be actually used, the driver must fill in the device
information fields 'manu', 'version', 'profile' and 'serial' in the capi_ctr
structure of the device, and signal its readiness by calling capi_ctr_ready().
From then on, Kernel CAPI may call the registered callback functions for the
device.
If the device becomes unusable for any reason (shutdown, disconnect ...), the
driver has to call capi_ctr_reseted(). This will prevent further calls to the
callback functions by Kernel CAPI.
3. Application Registration and Communication
Kernel CAPI forwards registration requests from applications (calls to CAPI
operation CAPI_REGISTER) to an appropriate hardware driver by calling its
register_appl() callback function. A unique Application ID (ApplID, u16) is
allocated by Kernel CAPI and passed to register_appl() along with the
parameter structure provided by the application. This is analogous to the
open() operation on regular files or character devices.
After a successful return from register_appl(), CAPI messages from the
application may be passed to the driver for the device via calls to the
send_message() callback function. The CAPI message to send is stored in the
data portion of an skb. Conversely, the driver may call Kernel CAPI's
capi_ctr_handle_message() function to pass a received CAPI message to Kernel
CAPI for forwarding to an application, specifying its ApplID.
Deregistration requests (CAPI operation CAPI_RELEASE) from applications are
forwarded as calls to the release_appl() callback function, passing the same
ApplID as with register_appl(). After return from release_appl(), no CAPI
messages for that application may be passed to or from the device anymore.
4. Data Structures
4.1 struct capi_driver
This structure describes a Kernel CAPI driver itself. It is used in the
register_capi_driver() and unregister_capi_driver() functions, and contains
the following non-private fields, all to be set by the driver before calling
register_capi_driver():
char name[32]
the name of the driver, as a zero-terminated ASCII string
char revision[32]
the revision number of the driver, as a zero-terminated ASCII string
int (*add_card)(struct capi_driver *driver, capicardparams *data)
a callback function pointer (may be NULL)
4.2 struct capi_ctr
This structure describes an ISDN device (controller) handled by a Kernel CAPI
driver. After registration via the attach_capi_ctr() function it is passed to
all controller specific lower layer interface and callback functions to
identify the controller to operate on.
It contains the following non-private fields:
- to be set by the driver before calling attach_capi_ctr():
struct module *owner
pointer to the driver module owning the device
void *driverdata
an opaque pointer to driver specific data, not touched by Kernel CAPI
char name[32]
the name of the controller, as a zero-terminated ASCII string
char *driver_name
the name of the driver, as a zero-terminated ASCII string
int (*load_firmware)(struct capi_ctr *ctrlr, capiloaddata *ldata)
(optional) pointer to a callback function for sending firmware and
configuration data to the device
void (*reset_ctr)(struct capi_ctr *ctrlr)
pointer to a callback function for performing a reset on the device,
releasing all registered applications
void (*register_appl)(struct capi_ctr *ctrlr, u16 applid,
capi_register_params *rparam)
void (*release_appl)(struct capi_ctr *ctrlr, u16 applid)
pointers to callback functions for registration and deregistration of
applications with the device
u16 (*send_message)(struct capi_ctr *ctrlr, struct sk_buff *skb)
pointer to a callback function for sending a CAPI message to the
device
char *(*procinfo)(struct capi_ctr *ctrlr)
pointer to a callback function returning the entry for the device in
the CAPI controller info table, /proc/capi/controller
read_proc_t *ctr_read_proc
pointer to the read_proc callback function for the device's proc file
system entry, /proc/capi/controllers/<n>; will be called with a
pointer to the device's capi_ctr structure as the last (data) argument
- to be filled in before calling capi_ctr_ready():
u8 manu[CAPI_MANUFACTURER_LEN]
value to return for CAPI_GET_MANUFACTURER
capi_version version
value to return for CAPI_GET_VERSION
capi_profile profile
value to return for CAPI_GET_PROFILE
u8 serial[CAPI_SERIAL_LEN]
value to return for CAPI_GET_SERIAL

=== 7 Kbuild syntax for exported headers
=== 7 Kbuild Variables
The kernel include a set of headers that is exported to userspace.
Many headers can be exported as-is but other headers requires a
minimal pre-processing before they are ready for user-space.
The pre-processing does:
- drop kernel specific annotations
- drop include of compiler.h
- drop all sections that is kernel internat (guarded by ifdef __KERNEL__)
Each relevant directory contain a file name "Kbuild" which specify the
headers to be exported.
See subsequent chapter for the syntax of the Kbuild file.
--- 7.1 header-y
header-y specify header files to be exported.
Example:
#include/linux/Kbuild
header-y += usb/
header-y += aio_abi.h
The convention is to list one file per line and
preferably in alphabetic order.
header-y also specify which subdirectories to visit.
A subdirectory is identified by a trailing '/' which
can be seen in the example above for the usb subdirectory.
Subdirectories are visited before their parent directories.
--- 7.2 objhdr-y
objhdr-y specifies generated files to be exported.
Generated files are special as they need to be looked
up in another directory when doing 'make O=...' builds.
Example:
#include/linux/Kbuild
objhdr-y += version.h
--- 7.3 destination-y
When an architecture have a set of exported headers that needs to be
exported to a different directory destination-y is used.
destination-y specify the destination directory for all exported
headers in the file where it is present.
Example:
#arch/xtensa/platforms/s6105/include/platform/Kbuild
destination-y := include/linux
In the example above all exported headers in the Kbuild file
will be located in the directory "include/linux" when exported.

--- What is TOMOYO? ---
TOMOYO is a name-based MAC extension (LSM module) for the Linux kernel.
LiveCD-based tutorials are available at
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/ubuntu8.04-live/
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/centos5-live/ .
Though these tutorials use non-LSM version of TOMOYO, they are useful for you
to know what TOMOYO is.
--- How to enable TOMOYO? ---
Build the kernel with CONFIG_SECURITY_TOMOYO=y and pass "security=tomoyo" on
kernel's command line.
Please see http://tomoyo.sourceforge.jp/en/2.2.x/ for details.
--- Where is documentation? ---

--- What is future plan? ---
We believe that inode based security and name based security are complementary
and both should be used together. But unfortunately, so far, we cannot enable
multiple LSM modules at the same time. We feel sorry that you have to give up
SELinux/SMACK/AppArmor etc. when you want to use TOMOYO.
We hope that LSM becomes stackable in future. Meanwhile, you can use non-LSM
version of TOMOYO, available at http://tomoyo.sourceforge.jp/en/1.6.x/ .
LSM version of TOMOYO is a subset of non-LSM version of TOMOYO. We are planning
to port non-LSM version's functionalities to LSM versions.

From: Linus Torvalds <torvalds () transmeta ! com>
Date: 1999-07-30 21:36:24
Cc'd to linux-kernel, because I don't write explanations all that often,
and when I do I feel better about more people reading them.
On Fri, 30 Jul 1999, David Mosberger wrote:

Basically, the new setup is:
- we have "real address spaces" and "anonymous address spaces". The
difference is that an anonymous address space doesn't care about the
user-level page tables at all, so when we do a context switch into an
anonymous address space we just leave the previous address space
active.
The obvious use for a "anonymous address space" is any thread that
doesn't need any user mappings - all kernel threads basically fall into
this category, but even "real" threads can temporarily say that for
some amount of time they are not going to be interested in user space,
and that the scheduler might as well try to avoid wasting time on
switching the VM state around. Currently only the old-style bdflush
sync does that.
- "tsk->mm" points to the "real address space". For an anonymous process,
tsk->mm will be NULL, for the logical reason that an anonymous process
really doesn't _have_ a real address space at all.
- however, we obviously need to keep track of which address space we
"stole" for such an anonymous user. For that, we have "tsk->active_mm",
which shows what the currently active address space is.
The rule is that for a process with a real address space (ie tsk->mm is
non-NULL) the active_mm obviously always has to be the same as the real
one.
For a anonymous process, tsk->mm == NULL, and tsk->active_mm is the
"borrowed" mm while the anonymous process is running. When the
anonymous process gets scheduled away, the borrowed address space is
returned and cleared.
To support all that, the "struct mm_struct" now has two counters: a
"mm_users" counter that is how many "real address space users" there are,
and a "mm_count" counter that is the number of "lazy" users (ie anonymous
users) plus one if there are any real users.
Usually there is at least one real user, but it could be that the real
user exited on another CPU while a lazy user was still active, so you do
actually get cases where you have a address space that is _only_ used by
lazy users. That is often a short-lived state, because once that thread
gets scheduled away in favour of a real thread, the "zombie" mm gets
released because "mm_users" becomes zero.
Also, a new rule is that _nobody_ ever has "init_mm" as a real MM any
more. "init_mm" should be considered just a "lazy context when no other
context is available", and in fact it is mainly used just at bootup when
no real VM has yet been created. So code that used to check
if (current->mm == &init_mm)
should generally just do
if (!current->mm)
instead (which makes more sense anyway - the test is basically one of "do
we have a user context", and is generally done by the page fault handler
and things like that).
Anyway, I put a pre-patch-2.3.13-1 on ftp.kernel.org just a moment ago,
because it slightly changes the interfaces to accomodate the alpha (who
would have thought it, but the alpha actually ends up having one of the
ugliest context switch codes - unlike the other architectures where the MM
and register state is separate, the alpha PALcode joins the two, and you
need to switch both together).

bool "ARM errata: Invalidation of the Instruction Cache operation can fail"

help
Invalidation of the Instruction Cache operation can

It does not affect the MPCore. This option enables the ARM Ltd.
recommended workaround.
config ARM_ERRATA_430973
bool "ARM errata: Stale prediction on replaced interworking branch"
depends on CPU_V7
help
This option enables the workaround for the 430973 Cortex-A8
(r1p0..r1p2) erratum. If a code sequence containing an ARM/Thumb
interworking branch is replaced with another code sequence at the
same virtual address, whether due to self-modifying code or virtual
to physical address re-mapping, Cortex-A8 does not recover from the
stale interworking branch prediction. This results in Cortex-A8
executing the new code sequence in the incorrect ARM or Thumb state.
The workaround enables the BTB/BTAC operations by setting ACTLR.IBE
and also flushes the branch target cache at every context switch.
Note that setting specific bits in the ACTLR register may not be
available in non-secure mode.
config ARM_ERRATA_458693
bool "ARM errata: Processor deadlock when a false hazard is created"
depends on CPU_V7
help
This option enables the workaround for the 458693 Cortex-A8 (r2p0)
erratum. For very specific sequences of memory operations, it is
possible for a hazard condition intended for a cache line to instead
be incorrectly associated with a different cache line. This false
hazard might then cause a processor deadlock. The workaround enables
the L1 caching of the NEON accesses and disables the PLD instruction
in the ACTLR register. Note that setting specific bits in the ACTLR
register may not be available in non-secure mode.
config ARM_ERRATA_460075
bool "ARM errata: Data written to the L2 cache can be overwritten with stale data"
depends on CPU_V7
help
This option enables the workaround for the 460075 Cortex-A8 (r2p0)
erratum. Any asynchronous access to the L2 cache may encounter a
situation in which recent store transactions to the L2 cache are lost
and overwritten with stale memory contents from external memory. The
workaround disables the write-allocate mode for the L2 cache via the
ACTLR register. Note that setting specific bits in the ACTLR register
may not be available in non-secure mode.

Choose Y here to warn whenever driver initialization logic needs
to change the pin multiplexing setup. When there are no warnings
printed, it's safe to deselect DAVINCI_MUX for your product.
config DAVINCI_RESET_CLOCKS
bool "Reset unused clocks during boot"
depends on ARCH_DAVINCI
help
Say Y if you want to reset unused clocks during boot.
This option saves power, but assumes all drivers are
using the clock framework. Broken drivers that do not
yet use clock framework may not work with this option.
If you are booting from another operating system, you
probably do not want this option enabled until your
device drivers work properly.
