drm/drivers: add support for using the arch wc mapping API.

2016-10-26T06:48:01+00:00

This fixes a regression in all these drivers since the cache
mode tracking was fixed for mixed mappings. It uses the new
arch API to add the VRAM range to the PAT mapping tracking
tables.

drm: use drm_file to tag vm-bos

2016-09-19T09:22:08+00:00

Rather than using "struct file*", use "struct drm_file*" as tag VM tag for
BOs. This will pave the way for "struct drm_file*" without any "struct
file*" back-pointer.

drm: Remove superflous linux/fb.h includes

2016-08-12T08:41:39+00:00

Everyone who uses the fbdev emulation helpers doesn't need to include
fb.h directly. Remove it.

drm/fb-helper: Add a dummy remove_conflicting_framebuffers

2016-08-12T08:41:18+00:00

Lots of drivers don't properly compile without this when CONFIG_FB=n.
It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when
it's disabled I think it makes sense to add it to drm_fb_helper.h.

Long term we probably need to rethink all the logic to unload firmware
framebuffer drivers, at least if we want to be able to move away from
CONFIG_FB and fbcon.

v2: Unfortunately just stubbing out remove_conflicting_framebuffers in
drm_fb_helper.h upset gcc about static vs. non-static declarations, so
a new wrapper it needs to be. Means more churn :(

drm/cirrus: Fix NULL pointer dereference when registering the fbdev

2016-08-09T03:01:47+00:00

cirrus_modeset_init() is initializing/registering the emulated fbdev
and, since commit c61b93fe51b1 ("drm/atomic: Fix remaining places where
!funcs->best_encoder is valid"), DRM internals can access/test some of
the fields in mode_config->funcs as part of the fbdev registration
process.
Make sure dev->mode_config.funcs is properly set to avoid dereferencing
a NULL pointer.

Merge remote-tracking branch 'airlied/drm-next' into topic/drm-misc

2016-07-19T07:27:29+00:00

Backmerge drm-next to be able to apply Chris' connector_unregister_all
cleanup (need latest i915 and sun4i state for that).

Also there's a trivial conflict in ttm_bo.c that git rerere fails to
remember.

drm/cirrus: make fbdev support really optional

2016-07-18T07:11:35+00:00

Currently enabling QEMU Cirrus DRM support automatically pulls
in fbdev dependency. However this dep is unnecessary since
DRM core already handles this for us (DRM_FBDEV_EMULATION).

drm/cirrus: Delete an unnecessary check before drm_gem_object_unreference_unlocked()

2016-07-18T07:11:30+00:00

The drm_gem_object_unreference_unlocked() function tests whether
its argument is NULL and then returns immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

It's pointless to only call the default implementation.
