drivers/gpu/drm/drm_ioc32.c: initialize all fields

2012-02-03T09:47:32+00:00

The c32 structure is allocated on the stack and its idx field is not
initialized before copying it to user level.  This patch takes the value
from the result of the ioctl, as done for the other fields.

drivers/gpu/drm: use printk_ratelimited instead of printk_ratelimit

2011-06-16T06:32:15+00:00

Since printk_ratelimit() shouldn't be used anymore (see comment in
include/linux/printk.h), replace it with printk_ratelimited.

drm: convert drm_ioctl to unlocked_ioctl

2009-12-18T01:22:31+00:00

drm_ioctl is called with the Big Kernel Lock held,
which shows up very high in statistics on vfs_ioctl.

Moving the lock into the drm_ioctl function itself
makes sure we blame the right subsystem and it gets
us one step closer to eliminating the locked version
of fops->ioctl.

Since drm_ioctl does not require the lock itself,
we only need to hold it while calling the specific
handler. The 32 bit conversion handlers do not
interact with any other code, so they don't need
the BKL here either and can just call drm_ioctl.

As a bonus, this cleans up all the other users
of drm_ioctl which now no longer have to find
the inode or call lock_kernel.

[airlied: squashed the non-driver bits
of the second patch in here, this provides
the flag for drivers to use to select unlocked
ioctls - but doesn't modify any drivers].

drm: Only use DRM_IOCTL_UPDATE_DRAW compat wrapper for compat X86.

2009-03-13T04:24:04+00:00

Only X86 32-bit uses a different alignment for "unsigned long long"
than it's 64-bit counterpart.

Therefore this compat translation is only correct, and only needed,
when either CONFIG_X86 or CONFIG_IA64.

drm: reorganise drm tree to be more future proof.

2008-07-14T00:45:01+00:00

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.

This restructures the drm along the lines of other kernel components.

It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
