Even for legacy userspace, since otherwise GETFB2 is broken and if you switch between modifier-less and modifier-aware compositors, smooth transitions break. Also it's just best practice to make sure modifiers are invariant for a given drm_fb, and that a modifier-aware kms drivers only has one place to store them, ignoring any old implicit bo flags or whatever else might float around. Motivated by some irc discussion with Bas about amdgpu modifier support. Acked-by:

When we swapout/in a BO we try to change the caching attributes of the pages before/after doing the copy. On x86 this is done by calling set_pages_uc(), set_memory_wc() or set_pages_wb() for not highmem pages to update the linear mapping of the page. On all other platforms we do exactly nothing. Now on x86 this is unnecessary because copy_highpage() will either create a temporary mapping of the page which is wb anyway and destroyed immediately again or use the linear mapping with the correct caching attributes. So stop this nonsense and just keep the caching as it is and return an error when a driver tries to change the caching of an already populated TT object. This is much more defensive since changing caching attributes is platform and driver specific and usually doesn't work after the page was initially allocated. Signed-off-by:

Commit 7053e0ea ("drm/vram-helper: stop using TTM placement flags") cleared the BO placement flags if top-down placement had been selected.

The vc4 display engine has a first controller called the HVS that will perform the composition of the planes. That HVS has 3 FIFOs and can therefore compose planes for up to three outputs. The timings part is generated through a component called the Pixel Valve, and the BCM2711 has 6 of them. Thus, the HVS has some bits to control which FIFO gets output to which Pixel Valve. The current code supports that muxing by looking at all the CRTCs in a new DRM atomic state in atomic_check, and given the set of constraints that we have, assigns FIFOs to CRTCs or reject the mode entirely. The actual muxing will occur during atomic_commit. However, that doesn't work if only a fraction of the CRTCs' state is updated in that state, since it will ignore the CRTCs that are kept running unmodified, and will thus unassign its associated FIFO, and later disable it. In order to make the code work as expected, let's pull the CRTC state of all the enabled CRTC in our atomic_check so that we can operate on all the running CRTCs, no matter whether they are affected by the new state or not.

Convert to using devm_drm_dev_alloc(), as drm_dev_init() is going away. v2: Remove drm_dev_put() since a) devres doesn't do refcounting, see Documentation/driver-api/driver-model/devres.rst, Section 4, paragraph 1; and since b) devres acts as garbage collector when the DRM device's parent's devres "action" callback is called to free the container device (amdgpu_device), which embeds the DRM dev.

Might want to extract this into helpers eventually, maybe as a mock_drm_dev_alloc or test_drm_dev_alloc. v4: - Fix IS_ERR handling (Matt) - Delete surplus put_device() in mock_device_release (intel-gfx-ci) v5: - do not switch to device_add - it breaks runtime pm in the tests and with the devres_group_add/release no longer needed for automatic cleanup (CI).

GPU drivers need this in their shrinkers, to be able to throw out mmap'ed buffers. Note that we also need dma_resv_lock in shrinkers, but that loop is resolved by trylocking in shrinkers. So full hierarchy is now (ignore some of the other branches we already have primed): mmap_read_lock -> dma_resv -> shrinkers -> i_mmap_lock_write I hope that's not inconsistent with anything mm or fs does, adding relevant people.
