drm/irq: Use unsigned int pipe in public API

2015-10-06T10:57:47+00:00

This continues the pattern started in commit cc1ef118fc09 ("drm/irq:
Make pipe unsigned and name consistent"). This is applied to the public
APIs and driver callbacks, so pretty much all drivers need to be updated
to match the new prototypes.

drm: Create drm legacy driver header

2014-09-12T09:08:55+00:00

And move a few legayc functions to start things over there.

It compiles ...

Inspired by a patch from Dave Airlie, but with a split between drm.ko
private legacy functions and stuff used by drivers.

drm: split ati_pcigart.h out of drmP.h

2014-09-12T04:11:14+00:00

Just move this into a separate header file, and make the
two users use it.

drm: const'ify ioctls table (v2)

2013-08-07T00:10:02+00:00

Because, there is no reason for it not to be const.

v1: original
v2: fix compile break in vmwgfx, and couple related cleanups suggested

drm/r128: Add test for initialisation to all ioctls that require it

2009-08-30T23:09:30+00:00

Almost all r128's private ioctls require that the CCE state has
already been initialised.  However, most do not test that this has
been done, and will proceed to dereference a null pointer.  This may
result in a security vulnerability, since some ioctls are
unprivileged.

This adds a macro for the common initialisation test and changes all
ioctl implementations that require prior initialisation to use that
macro.

Also, r128_do_init_cce() does not test that the CCE state has not
been initialised already.  Repeated initialisation may lead to a crash
or resource leak.  This adds that test.

drm: move drm vblank initialization/cleanup to driver load/unload

2008-11-24T23:49:03+00:00

drm vblank initialization keeps track of the changes in driver-supplied
frame counts across vt switch and mode setting, but only if you let it by
not tearing down the drm vblank structure.

drm: Rework vblank-wait handling to allow interrupt reduction.

2008-10-17T21:10:11+00:00

Previously, drivers supporting vblank interrupt waits would run the interrupt
all the time, or all the time that any 3d client was running, preventing the
CPU from sleeping for long when the system was otherwise idle.  Now, interrupts
are disabled any time that no client is waiting on a vblank event. The new
method uses vblank counters on the chipsets when the interrupts are turned
off, rather than counting interrupts, so that we can continue to present
accurate vblank numbers.
