drm/prime: drop reference on imported dma-buf come from gem

2013-01-17T16:46:11+00:00

commit be8a42ae60addd8b6092535c11b42d099d6470ec upstream.

Increasing ref counts of both dma-buf and gem for imported dma-buf come from gem
makes memory leak. release function of dma-buf cannot be called because f_count
of dma-buf increased by importing gem and gem ref count cannot be decrease
because of exported dma-buf.

So I add dma_buf_put() for imported gem come from its own gem into each drivers
having prime_import and prime_export capabilities. With this, only gem ref
count is increased if importing gem exported from gem of same driver.

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

2012-11-22T08:55:17+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)

Fixes the following sparse warnings:
drivers/gpu/drm/exynos/exynos_drm_fimd.c:65:25: warning:
symbol 'exynos4_fimd_driver_data' was not declared. Should it be static?

drm/exynos: fix overlay updating issue

2012-11-22T08:55:17+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.

drm/exynos: add support for ARCH_MULTIPLATFORM

2012-10-31T13:11:36+00:00

Exynos does not seem to have any dependency on anything from
platform headers so just needs Kconfig updated to build in
ARCH_MULTIPLATFORM builds.

drm/exynos: fix display on issue

2012-10-31T13:11:29+00:00

When crtc_funcs->dpms callback is called, exynos_crtc->dpms
and exynos_encoder->dpms are changed to new mode. But if user
requests dpms mode operation, OFF -> ON, when crtc's dpms callback
is called, exynos_encoder->dpms is also changed to ON. This
makes encoder's dpms callback call be ignored so display power
couldn't become on again.

This patch removes exynos_encoder->dpms changing and adds 'updated'
variable to exynos_drm_encoder structure to avoid duplicated overlay
updating.

Merge tag 'fbdev-updates-for-3.7' of git://github.com/schandinat/linux-2.6

2012-10-12T01:21:02+00:00

Pull fbdev updates from Florian Tobias Schandinat:
 "This includes:
   - large updates for OMAP
     - basic OMAP5 DSS support for DPI and DSI outputs
     - large cleanups and restructuring
   - some update to Exynos and da8xx-fb
   - removal of the pnx4008 driver (arch removed)
   - various other small patches"

Fix up some trivial conflicts (mostly just include line changes, but
also some due to the renaming of the deferred work functions by Tejun).
