Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference.

2023-11-14drm/format-helper: Pass format-conversion state to helpersThomas Zimmermann1-28/+44
Pass an instance of struct drm_format_conv_state to DRM's format conversion helpers. Update all callers. Most drivers can use the format-conversion state from their shadow- plane state. The shadow plane's destroy function releases the allocated buffer. Drivers will later be able to allocate a buffer of appropriate size in their plane's atomic_check code. The gud driver uses a separate thread for committing updates. For now, the update worker contains its own format-conversion state. Images in the format-helper tests are small. The tests preallocate a static page for the temporary buffer. Unloading the module releases the memory. v6: * update patch for ssd132x support v5: * avoid using unusupported shadow-plane state in repaper (Noralf) * fix documentation (Noralf, kernel test robot) v3: * store buffer in shadow-plane state (Javier, Maxime) * replace ARRAY_SIZE() with sizeof() (Jani) Signed-off-by: Thomas Zimmermann <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> Tested-by: Javier Martinez Canillas <[email protected]> # ssd130x Cc: Noralf Trønnes <[email protected]> Cc: Javier Martinez Canillas <[email protected]> Cc: Gerd Hoffmann <[email protected]> Cc: David Lechner <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2023-11-09drm/tests: Remove slow testsMaxime Ripard2-2369/+0
Both the drm_buddy and drm_mm tests have been converted from selftest to kunit recently. However, a significant portion of them are trying to exert some part of their API over a huge number of iterations and with random variations of their parameters. They are thus more a way to discover new bugs than actual unit tests. This is fine in itself but leads to very slow runtime (up to 25s for some drm_test_mm_reserve and drm_test_mm_insert on a Ryzen 7950x while running the tests in qemu) which make them a poor fit for kunit. Let's remove those tests from the drm_mm and drm_buddy test suites for now, and if it's ever needed we can always create proper unit tests for them later on. This made the entire DRM tests execution time (as of v6.6-rc1) come from 65s to less than .5s on a Ryzen 7950x system when running under qemu, and from 9 minutes to about 4s on a RaspberryPi4.

2023-11-08drm/dp_mst: Fix fractional DSC bpp handlingVille Syrjälä1-3/+3
The current code does '(bpp << 4) / 16' in the MST PBN calculation, but that is just the same as 'bpp' so the DSC codepath achieves absolutely nothing. Fix it up so that the fractional part of the bpp value is actually used instead of truncated away. 64*1006 has enough zero lsbs that we can just shift that down in the dividend and thus still manage to stick to a 32bit divisor. And while touching this, let's just make the whole thing more straightforward by making the passed in bpp value .4 binary fixed point always, instead of having to pass in different things based on whether DSC is enabled or not. v2: - Fix DSC kunit test cases.

2023-08-10drm/test: drm_exec: fix memory leak on object prepareDanilo Krummrich1-2/+5
drm_exec_prepare_obj() and drm_exec_prepare_array() both reserve dma-fence slots and hence a dma_resv_list without ever freeing it. Make sure to call drm_gem_private_object_fini() for each GEM object passed to drm_exec_prepare_obj()/drm_exec_prepare_array() throughout the test to fix this up. While at it, remove some trailing empty lines.

2023-07-31drm/tests: helpers: Create a helper to allocate an atomic stateMaxime Ripard1-0/+46
As we gain more tests, boilerplate to allocate an atomic state and free it starts to be there more and more as well. In order to reduce the allocation boilerplate, we can create a helper to create that atomic state, and call an action when the test is done. This will also clean up the exit path.

As we get more and more tests, the locking context initialisation creates more and more boilerplate, both at creation and destruction. Let's create a helper that will allocate, initialise a context, and register kunit actions to clean up once the test is done.
