UAPI: (Scripted) Remove redundant DRM UAPI header #inclusions from drivers/gpu/.

2012-10-02T17:01:05+00:00

Remove redundant DRM UAPI header #inclusions from drivers/gpu/.

Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and
drm_sarea.h).  They are now #included via drmP.h and drm_crtc.h via a preceding
patch.

Without this patch and the patch to make include the UAPI headers from the core
headers, after the UAPI split, the DRM C sources cannot find these UAPI headers
because the DRM code relies on specific -I flags to make #include "..."  work
on headers in include/drm/ - but that does not work after the UAPI split without
adding more -I flags.

drm: use drm_compat_ioctl for 32-bit apps

2012-09-05T20:55:02+00:00

Most of the DRM drivers appear to be missing the .compat_ioctl file
operation entry necessary for 32-bit application compatibility.

This patch  uses drm_compat_ioctl for all drivers which don't have
their own, and which are using drm_ioctl for .unlocked_ioctl.

This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
.unlocked_ioctl and will presumably need a custom .compat_ioctl as
well.

drm: kill dma queue support

2012-07-20T02:50:55+00:00

Absolutely unused. All the values are only ever initialized and
then used at most in some debug printout functions.

Revert "Revert "drm/i810: cleanup reclaim_buffers""

2012-07-20T02:49:49+00:00

This reverts commit 6e877b576ddf7cde5db2e9a6dcb56fef0ea77e64,
reinstating the original commit:

    drm/i810: cleanup reclaim_buffers

    My dear old i815 always hits the deadlocked on reclaim_buffers
    warning. Switch over to the idlelock duct-tape on hope that
    works better. I've fired up my i815 and now closing glxgears doesn't
    take 5 seconds anymore. \o/

The original problem with that was that I've moved it ahead in the
series so that it could be included despite some patches not being
ready quite yet. The little problem is that this patch required some
of the previous rework to work correctly.

Now that everything is in the right order again, this actually works
on my i810 and does speed up closing gl apps as the original commit
claimed. Without hanging the machine, as the revert says.

i810: switch to vm_mmap()

2012-05-31T01:04:54+00:00

Weirdness around do_mmap() in there does not rely on ->mmap_sem for
exclusion, so no need to keep it under that.  As the result, we can
turn that do_mmap() into vm_mmap().

VM: add "vm_mmap()" helper function

2012-04-21T00:29:13+00:00

This continues the theme started with vm_brk() and vm_munmap():
vm_mmap() does the same thing as do_mmap(), but additionally does the
required VM locking.

This uninlines (and rewrites it to be clearer) do_mmap(), which sadly
duplicates it in mm/mmap.c and mm/nommu.c.  But that way we don't have
to export our internal do_mmap_pgoff() function.

Some day we hopefully don't have to export do_mmap() either, if all
modular users can become the simpler vm_mmap() instead.  We're actually
very close to that already, with the notable exception of the (broken)
use in i810, and a couple of stragglers in binfmt_elf.

VM: add "vm_munmap()" helper function

2012-04-21T00:29:13+00:00

Like the vm_brk() function, this is the same as "do_munmap()", except it
does the VM locking for the caller.

drm: drop setting vm_file to filp

2012-03-05T11:19:08+00:00

Talking to Al Viro on irc, we can see no possible reason for doing
this, the upper mmap code does it. The code has been there since
first import into drm tree I can find.

Al tracked down this as a requirement pre 2.3.51 hasn't been needed since.
