drm/exynos: Remove redundant error messages

2013-09-05T04:43:43+00:00

kzalloc already has built-in error messages. Hence remove
additional ones.

drm/exynos: Remove tracking log functions

2013-06-28T12:13:55+00:00

This patch removes tracking log functions which were used to debug
in the early development stage and are not so important as were.
So remove them for code clean up.

drm/exynos: change file license to GPL

2013-01-04T06:54:32+00:00

This patch changes file license to GPL

Most of exynos files had been copied from some random
file and not updated correctly. So this patch corrects
the file license.

drm/exynos: make wait_for_vblank a manager op

2012-12-13T14:05:43+00:00

Changelog v2:
remove unnecessay wait_for_vblank call.
- with this patch, wait_for_vblank callback is moved from
  overlay ops to manager ops so it should be removed and
  it doesn't need to wait vblank signal at plane disable.

Changelog v1:
The wait_for_vblank callback is moved from overlay ops to manager ops
of exynos drm driver. Also, the check for DPMS OFF of encoder is
removed before calling wait_for_vblank.

Merge branch 'drm-next-3.8' of git://people.freedesktop.org/~agd5f/linux into drm-next

2012-12-10T10:03:58+00:00

Alex writes:
Pretty minor -next pull request.  We some additional new bits waiting
internally for release.  Hopefully Monday we can get at least some of
them out.  The others will probably take a few more weeks.

Highlights of the current request:
- ELD registers for passing audio information to the sound hardware
- Handle GPUVM page faults more gracefully
- Misc fixes

drm/exynos: make sure that overlay data are updated

2012-12-05T05:39:19+00:00

Changelog v2:
fix a little bit performance issue to previous patch.
- When drm framebuffer is destroyed, make sure that overlay
  data are updated to real hardwrae for all encoders
  instead of waiting for vblank every page flip request.
  For this, it adds a new function,
  exynos_drm_encoder_complete_scanout function.

Changelog v1:
This patch removes wait_for_vblank call from
exynos_drm_encoder_plane_disable function and move it to
exynos_drm_encoder_plane_commit function.

Disabling dma channel to each plane doens't need vblank
signal to update data to real hardware. But updating
overlay data to real hardware does need vblank signal.

drm/exynos: Fix potential NULL pointer dereference in exynos_drm_encoder.c

2012-11-29T11:30:33+00:00

Check overlay_ops is not NULL as checked in the previous 'if' condition.
Fixes the following smatch error:
drivers/gpu/drm/exynos/exynos_drm_encoder.c:509 exynos_drm_encoder_plane_disable()
error: we previously assumed 'overlay_ops' could be null (see line 499)

drm/exynos: fix overlay updating issue

2012-11-29T11:30:33+00:00

Chagelog v2:
Move encoder's dpms updating into exynos_drm_encoder_commit
function because when crtc's dpms is updated, encoder's dpms
is updated also. This would induce the issue that encoder
isn't disabled after crtc is disabled.

Changelog v1:
This patch fixes a issue that overlay data aren't applied
to real hardware when dpms off goes to on after setcrtc
was requested like below,
    dpms off -> setcrtc -> dpms off -> dpms on

For this, it makes encoder's dpms to be updated when
setcrtc is requested.
