Highlights: - new drivers: MSM driver from Rob Clark - non-drm: switcheroo and hdmi audio driver support for secondary GPU poweroff, so drivers can use runtime PM to poweroff the GPUs. This can save 5 or 6W on some optimus laptops. - drm core: combined GEM and TTM VMA manager per-filp mmap permission tracking initial rendernode support (via a runtime enable for now, until we get api stable), remove old proc support, lots of cleanups of legacy code hdmi vendor infoframes and 4k modes lots of gem/prime locking and races fixes async pageflip scaffolding drm bridge objects - i915: Haswell PC8+ support and eLLC support, HDMI 4K support, initial per-process VMA pieces, watermark reworks, convert to generic hdmi infoframes, encoder reworking, fastboot support, - radeon: CIK PM support, remove 3d blit code in favour of DMA engines, Berlin GPU support, HDMI audio fixes - nouveau: secondary GPU power down support for optimus laptops, lots of fixes, use MSI, VP3 engine support - exynos: runtime pm support for g2d, DT support, remove non-DT, - tda998x i2c driver: lots of fixes for sync issues - gma500: lots of cleanups - rcar: add LVDS support, fbdev emulation, - tegra: just minor fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (684 commits) drm/exynos: Fix build error with exynos_drm_connector.c drm/exynos: Remove non-DT support in exynos_drm_fimd drm/exynos: Remove non-DT support in exynos_hdmi drm/exynos: Remove non-DT support in exynos_drm_g2d drm/exynos: Remove non-DT support in exynos_hdmiphy drm/exynos: Remove non-DT support in exynos_ddc drm/exynos: Make Exynos DRM drivers depend on OF drm/exynos: Consider fallback option to allocation fail drm/exynos: fimd: move platform data parsing to separate function drm/exynos: fimd: get signal polarities from device tree drm/exynos: fimd: replace struct fb_videomode with videomode drm/exynos: check a pixel format to a particular window layer drm/exynos: fix fimd pixel format setting drm/exynos: Add NULL pointer check drm/exynos: Remove redundant error messages drm/exynos: Add missing of.h header include drm/exynos: Remove redundant NULL check in exynos_drm_buf drm/exynos: add device tree support for rotator drm/exynos: Add missing includes drm/exynos: add runtime pm interfaces to g2d driver ... 2013-09-03T23:01:02Z Dave Airlie airlied@redhat.com 2013-09-03T23:01:02Z urn:sha1:ef25bd84edba73f78ce7397ef3d7b97e2774ed07 drm/tegra: Changes for v3.12-rc1 Only a couple of small patches this time around.

Doing this as early as possible prevents any other resources from being requested and enabled, therefore reducing the need to cleanup on deferred probe while at the same time not wasting precious CPU cycles determining if probing needs to be deferred or not.

Instead of crashing in such a situation, propagate the error to callers of the host1x_get_drm_data() function.

It's now time to shuffle around the naming of hdmi_hdmi_infoframe to make hdmi_vendor_infoframe become the HDMI vendor specific structure.

Port the host1x driver to use those so I can refactor the infoframe code a bit more. This changes the length of the infoframe payload from 6 to 5, which is enough for the "frame packing" stereo format. v2: Pimp up the commit message with the note about the length (Ville Syrjälä) Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Terje Bergström <tbergstrom@nvidia.com> Cc: linux-tegra@vger.kernel.org Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Reviewed-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Dave Airlie <airlied@gmail.com> 2013-08-27T08:20:12Z Dan Carpenter dan.carpenter@oracle.com 2013-08-23T10:19:11Z urn:sha1:745cecc07cee878a5afdda40d13f8b0901a88ebd There is a mistake here so it returns PTR_ERR(NULL) which is success instead of -ENOMEM.

On 32 bit systems then size_t is 32 bits so "total" will never be higher than UINT_MAX because of integer overflows. We need cast to u64 first before doing the math. Also the addition earlier: unsigned int num_unpins = num_cmdbufs + num_relocs; That can overflow as well, but I think it's still safe because we check both "num_cmdbufs" and "num_relocs" again in this test.
