drm/i915: add support for G41 chipset

2009-05-08T22:45:03+00:00

commit 72021788678523047161e97b3dfed695e802a5fd upstream.

This had been delayed for some time due to failure to work on the one piece
of G41 hardware we had, and lack of success reports from anybody else.
Current hardware appears to be OK.

drm: fix EDID parser problem with positive/negative hsync/vsync

2009-03-11T02:18:48+00:00

Comparing the layouts of struct detail_pixel_timing with
x.org's struct detailed_timings and how those are handled,
it appears that the hsync_positive and vsync_positive
fields are backwards.

This patch fixes https://bugs.freedesktop.org/show_bug.cgi?id=20019
for me. It was tested on 2 monitors, LG FLATRON L225WS 22" and
a YAKUMO 17" for which more details are unknown.

drm: disable encoders before re-routing them

2009-02-25T04:42:23+00:00

In some cases we may receive a mode config that has a different
CRTC<->encoder map that the current configuration.  In that case, we
need to disable any re-routed encoders before setting the mode,
otherwise they may not pick up the new CRTC (if the output types are
incompatible for example).

drm/i915: Keep refs on the object over the lifetime of vmas for GTT mmap.

2009-02-20T02:21:13+00:00

This fixes potential fault at fault time if the object was unreferenced
while the mapping still existed.  Now, while the mmap_offset only lives
for the lifetime of the object, the object also stays alive while a vma
exists that needs it.

Check the error paths within intel_pipe_set_base() to first cleanup and
then report back the error.

drm/i915: add fence register management to execbuf

2009-02-08T11:38:02+00:00

Adds code to set up fence registers at execbuf time on pre-965 chips as
necessary.  Also fixes up a few bugs in the pre-965 tile register support
(get_order != ffs).  The number of fences available to the kernel defaults
to the hw limit minus 3 (for legacy X front/back/depth), but a new parameter
allows userspace to override that as needed.

drm: Rip out the racy, unused vblank signal code.

2009-01-28T15:50:14+00:00

Schedule a vblank signal, kill the process, and we'll go walking over freed
memory.  Given that no open-source userland exists using this, nor have I
ever heard of a consumer, just let this code die.

drm: create mode_config idr lock

2009-01-22T07:53:05+00:00

Create a separate mode_config IDR lock for simplicity.  The core DRM
config structures (connector, mode, etc. lists) are still protected by
the mode_config mutex, but the CRTC IDR (used for the various identifier
IDs) is now protected by the mode_config idr_mutex.  Simplifies the
locking a bit and removes a warning.

All objects are protected by the config mutex, we may in the future,
split the object further to have reference counts.
