The PS3 Sixaxis controller has 4 LEDs which can be controlled using the same
command as the rumble functionality. It seems not to be possible to only change
the LED without modifying the rumble motor state. Thus both have to be stored
on the host and retransmitted when either the LED or rumble state is changed.
Third party controllers may not support to disable all LEDs at once. These
controllers automatically switch to blinking of all LEDs when no LED is active
anymore.

The ff_memless has a timer running which gets run in an atomic context and
calls the play_effect callback. The callback function for sony uses the
hid_output_raw_report (overwritten by sixaxis_usb_output_raw_report) function
to handle differences in the control message format. It is not safe for an
atomic context because it may sleep later in usb_start_wait_urb.
This "scheduling while atomic" can cause the system to lock up. A workaround is
to make the force feedback state update using work_queues and use the
play_effect function only to enqueue the work item.

Sony Dualshock 3 controllers have two motors which can be used to provide
simple force feedback rumble effects. The right motor is can be used to create
a weak rumble effect but does not allow to set the force. The left motor is

The state of both motors can be changed using HID_OUTPUT_REPORT packets and

It is safe to use devres allocation within the hid subsystem:
- the devres release is called _after_ the call to .remove(), meaning
that no freed pointers will exists while removing the device
- if a .probe() fails, devres releases all the allocated ressources
before going to the next driver: there will not be ghost ressources
attached to a hid device if several drivers are probed.
Given that, we can clean up a little some of the HID drivers. These ones
are trivial:
- there is only one kzalloc in the driver
- the .remove() callback contains only one kfree on top of hid_hw_stop()
- the error path in the probe is easy enough to be manually checked

There are some Sony clone gamepads that are incompatible
with PS3 since firmware 3.50, as they decided to prevent those
devices to work, without any good technical reason. I was one of those
'blessed' people affected by their niceness with their customers.
Marcelo also has another device with a similar problem.
Perhaps due to Sony's way to block the device, damaging the device's
eeprom, or perhaps because they just have a different, broken Report
descriptor, there are 3 buttons that don't work on both devices
(the ones equivalent to square, round and X).
What it happens is that the descriptor generate weird EV_ABS events
to those buttons, instead of EV_MSC/EV_KEY.
A fix that seems to be enough for them is to return the original
sixaxis table instead of the broken one. That's what this patch
does.
Yet, there are some missing entries at the used keytable. On my
tests, all keys are now producing the right events, but the reported
keycodes look weird:
"square" key: (Button.0010 = 1)
1355524363.460835: event type EV_MSC(0x04): scancode = 0x90010
1355524363.460835: event type EV_KEY(0x01) key_up: BTN_DEAD(0x0001)
"round" key: (Button.000e = 1)
1355524410.908705: event type EV_MSC(0x04): scancode = 0x9000e
1355524410.908705: event type EV_KEY(0x01) key_down: (0x0001)
1355524410.971788: event type EV_MSC(0x04): scancode = 0x9000e
1355524410.971788: event type EV_KEY(0x01) key_up: (0x0001)
"X" key: (Button.000f = 1)
1355524384.880813: event type EV_MSC(0x04): scancode = 0x9000f
1355524384.880813: event type EV_KEY(0x01) key_down: (0x0001)
1355524384.979815: event type EV_MSC(0x04): scancode = 0x9000f
1355524384.979815: event type EV_KEY(0x01) key_up: (0x0001)
The rationale is likely due to those entries at rdesc table, where the
Kernel were not likely able to parse:
Button.000d ---> Key.?
Button.000e ---> Key.?
Button.000f ---> Key.?
Button.0010 ---> Key.BtnDead
Button.0011 ---> Key.?
Button.0012 ---> Key.?
Button.0013 ---> Key.?
As a reference, this is the rdisc used on my clone (a Mad Catz
model 8846):

This is what's returned on Marcelo's device (not sure what is
the brand name of his device):

maximum value would be around +/-32768 = 8G.

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.
