HDMI 2.0/CEA-861-F introduces two new aspect ratios: - 64:27 - 256:135 This patch: - Adds new DRM flags for to represent these new aspect ratios. - Adds new cases to handle these aspect ratios while converting from user->kernel mode or vise versa. V2: Rebase V3: Align macro for DRM_MODE_PICTURE_ASPECT_256_135 (Jim Bride) V4: Added r-b from Jose. Signed-off-by:

Shashank Sharma authored
Current DRM layer functions don't parse aspect ratio information while converting a user mode->kernel mode or vice versa. This causes modeset to pick mode with wrong aspect ratio, eventually causing failures in HDMI compliance test cases, due to wrong VIC. This patch adds aspect ratio information in DRM's mode conversion and mode comparision functions, to make sure kernel picks mode with right aspect ratio (as per the VIC). V2: Addressed review comments from Sean: - Fix spellings/typo - No need to handle aspect ratio none - Add a break, for default case too V3: Rebase V4: Added r-b from Jose Signed-off-by:

drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics). This is even more beneficial when the lifetime of the state becomes more convoluted than being passed to a single worker thread for the commit. v2: Double check !intel atomic_commit functions for missing gets v3: Update kerneldocs Signed-off-by:

Chris Wilson authored
In order to be completely generic, we have to double check the read seqlock after acquiring a reference to the fence. If the driver is allocating fences from a SLAB_DESTROY_BY_RCU, or similar freelist, then within an RCU grace period a fence may be freed and reallocated. The RCU read side critical section does not prevent this reallocation, instead we have to inspect the reservation's seqlock to double check if the fences have been reassigned as we were acquiring our reference.

This variant of fence_get_rcu() takes an RCU protected pointer to a fence and carefully returns a reference to the fence ensuring that it is not reallocated as it does. This is required when mixing fences and SLAB_DESTROY_BY_RCU - although it serves a more pedagogical function atm Signed-off-by:

Some boards have an entirely passive RGB to VGA bridge, based on DACs implemented by resistor ladders. Those might or might not have an i2c bus routed to the VGA connector in order to access the screen EDIDs. Add a bridge that doesn't do anything but expose the modes available on the screen, either based on the EDIDs if available, or based on the XGA standards. Acked-by:

dma_buf may live a long time, longer than the last direct user of the driver. We already hold a reference to the owner module (that prevents the object code from disappearing), but there is no reference to the drm_dev - so the pointers to the driver backend themselves may vanish. v2: Resist temptation to fix the bug in armada_gem.c not setting the correct flags on the exported dma-buf (it should pass the flags through and not be arbitrarily setting O_RDWR). Use a common wrapper for exporting the dmabuf and acquiring the reference to the drm_device. Testcase: igt/vgem_basic/unload Suggested-by:

dma_buf_export() adds a reference to the owning module to the dmabuf (to prevent the driver from being unloaded whilst a third party still refers to the dmabuf). However, drm_gem_prime_export() was passing its own THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right owner from the device->fops instead. v2: Use C99 initializers to zero out unset elements of dma_buf_export_info v3: Extract the right module from dev->fops.

There's no point in enabling PSR when the panel doesn't support it. This also avoids a problem when PSR gets enabled when a CRTC is being disabled, because sometimes in that situation the DSP_HOLD_VALID_INTR interrupt on which we wait will never arrive. This was observed on RK3288 with a panel without PSR (veyron-jaq Chromebook). It's very easy to reproduce by running the kms_rmfb test in IGT a few times.

It's not that obvious how a driver can all race the atomic commit with handling the completion event. And there's unfortunately a pile of drivers with rather bad event handling which misdirect people into the wrong direction. Try to remedy this by documenting everything better. v2: Type fixes Alex spotted. v3: More typos Alex spotted.

As part of the sync framework destaging, the sync_file.h header was moved, but an entry was not added on Kbuild to install it. This patch resolves this omission so that "make headers_install" installs this header. Fixes: 460bfc41 ("dma-buf/sync_file: de-stage sync_file headers") Reported-by:
