drm/omap: Fix error handling path in 'omap_dmm_probe()'

2018-02-03T16:04:29+00:00

[ Upstream commit 8677b1ac2db021ab30bb1fa34f1e56ebe0051ec3 ] If we don't find a matching device node, we must free the memory allocated in 'omap_dmm' a few lines above.

drm/omap: fix dmabuf mmap for dma_alloc'ed buffers

2017-12-20T09:04:54+00:00

[ Upstream commit 9fa1d7537242bd580ffa99c4725a0407096aad26 ] omap_gem_dmabuf_mmap() returns an error (with a WARN) when called for a buffer which is allocated with dma_alloc_*(). This prevents dmabuf mmap from working on SoCs without DMM, e.g. AM4 and OMAP3. I could not find any reason for omap_gem_dmabuf_mmap() rejecting such buffers, and just removing the if() fixes the limitation.

drm/omap: fix fbdev pix format to support all platforms

2015-12-14T08:00:22+00:00

omap_fbdev always creates a framebuffer with ARGB8888 pixel format. On OMAP3 we have VIDEO1 overlay that does not support ARGB8888, and on OMAP2 none of the overlays support ARGB888. This patch changes the omap_fbdev's fb to XRGB8888, which is supported by all platforms. Signed-off-by: Tomi Valkeinen Tested-by: H. Nikolaus Schaller Acked-by: Laurent Pinchart

drm: Check crtc viewport correctly with rotated primary plane on atomic drivers

2015-10-19T09:00:47+00:00

On atomic drivers we can dig out the primary plane rotation from the plane state instead of looking at the legacy crtc->invert_dimensions flag. The flag is not set by anyone except omapdrm, and it would be racy to set it the same way in the atomic helpers. v2: Kill crtc->invert_dimensions totally since omap is state based already and no one else ever used it (Matt) Cc: Matt Roper Cc: Tvrtko Ursulin Cc: Daniel Vetter Cc: Tomi Valkeinen Cc: Rob Clark Signed-off-by: Ville Syrjälä Link: http://patchwork.freedesktop.org/patch/msgid/1445009919-22746-1-git-send-email-ville.syrjala@linux.intel.com Reviewed-by: Matt Roper Signed-off-by: Daniel Vetter

drm/: Drop DRM_UNLOCKED from modeset drivers

2015-10-16T13:50:54+00:00

Just one special case (since i915 lost its ums code, yay): - radeon: Has slots for the old ums ioctls which don't have DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it everywhere. Every other kms driver just has DRM_UNLOCKED for all their ioctls, as they should. v2: admgpu happened, include that one too. And i915 lost its UMS support which means we can change all the i915 ioctls too. v3: Rebased on top of new vmwgfx DX interface extensions. v4: Rebase on top of render-node support in exynos.

drm: Stop using drm_vblank_count() as the hw frame counter

2015-10-07T14:13:52+00:00

drm_vblank_count() returns the software counter. We should not pretend it's the hw counter since we use the hw counter to figuere out what the software counter value should be. So instead provide a new function drm_vblank_no_hw_counter() for drivers that don't have a real hw counter. The new function simply returns 0, which is about the only thing it can do.

drm/irq: Use unsigned int pipe in public API

2015-10-06T10:57:47+00:00

This continues the pattern started in commit cc1ef118fc09 ("drm/irq: Make pipe unsigned and name consistent"). This is applied to the public APIs and driver callbacks, so pretty much all drivers need to be updated to match the new prototypes.

drm: Spell vga_switcheroo consistently

2015-09-24T18:14:19+00:00

Currently everyone and their dog has their own favourite spelling for vga_switcheroo. This makes it hard to grep dmesg for log entries relating to vga_switcheroo. It also makes it hard to find related source files in the tree. vga_switcheroo.c uses pr_fmt "vga_switcheroo". Use that everywhere. Signed-off-by: Lukas Wunner Signed-off-by: Daniel Vetter
