drm/omap: fix tiled buffer stride calculations

2018-04-13T17:50:16+00:00

[ Upstream commit cc8dd7661ccc2d8dc88921da8e6cc7c2fcdb0341 ]

omap_gem uses page alignment for buffer stride. The related calculations
are a bit off, though, as byte stride of 4096 gets aligned to 8192,
instead of 4096.

This patch changes the code to use DIV_ROUND_UP(), which fixes those
calculations and makes them more readable.

drm/omap: DMM: Check for DMM readiness after successful transaction commit

2018-03-24T09:58:48+00:00

[ Upstream commit b7ea6b286c4051e043f691781785e3c4672f014a ]

Check the status of the DMM engine after it is reported that the
transaction was completed as in rare cases the engine might not reached a
working state.

The wait_status() will print information in case the DMM is not reached the
expected state and the dmm_txn_commit() will return with an error code to
make sure that we are not continuing with a broken setup.

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

[ 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.

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)

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.
