igt_check_plane_state test crashes in drm_atomic_helper_check_plane_state when trying to de-reference drm_plane_state->plane->dev due to the lack of a struct drm_plane in the mock struct drm_plane_state. Since drm_plane_state always should contain a plane, the mock also needs a plane to be the test more robust and realistic. Add it. Signed-off-by:

eDP 1.4 adds a table of link rates supported by the sink to DPCD, as well as a LINK_RATE_SET register to select between the entries in it. If present, we will use this data to generate our internal link rate table rather than using the standard list based on MAX_LINK_RATE. Some recent laptops report MAX_LINK_RATE=0, and require this support. Signed-off-by:

vmw_user_bo_lookup can fail to lookup user buffers, especially because the buffer handles come from the userspace. The return value has to be checked before the buffers are put back.

Before the driver had screen targets support we had to disable explicit bringup of its infrastructure because it was breaking screen objects support. Since the implementation of screen targets landed there hasn't been a reason to explicitly disable it and the options were never used. Remove of all that unused code. Signed-off-by:

Old versions of the svga device used to export virtual vram, handling of which was optimized on top of transparent hugepages support. Only very old devices (OpenGL 2.1 support and earlier) used this code and at this point performance differences are negligible. Because the code requires very old hardware versions to run it has been largely untested and unused for a long time. Furthermore removal of the ttm hugepages support in: commit 0d979509 ("drm/ttm: remove ttm_bo_vm_insert_huge()") broke the coherency mode in vmwgfx when running with hugepages.

This changes the way the regmap is allocated to prepare for the later addition of the JZ4780 which has more registers and bits than the others. Therefore we make the regmap as big as the reg property in the device tree tells. Suggested-by:

Several DRM/KMS atomic commits can run in parallel if they affect different CRTC. These commits share the global HVS state, so we have some code to make sure we run commits in sequence. This synchronization code is one of the first thing that runs in vc4_atomic_commit_tail(). Another constraints we have is that we need to make sure the HVS clock gets a boost during the commit. That code relies on clk_set_min_rate and will remove the old minimum and set a new one. We also need another, temporary, minimum for the duration of the commit. The algorithm is thus to set a temporary minimum, drop the previous one, do the commit, and finally set the minimum for the current mode. However, the part that sets the temporary minimum and drops the older one runs before the commit synchronization code. Thus, under the proper conditions, we can end up mixing up the minimums and ending up with the wrong one for our current step. To avoid it, let's move the clock setup in the protected section.

There are a few details specific to the GETFB2 IOCTL. It's not immediately clear how user-space should check for the number of planes. Suggest using the handles field or the pitches field. The modifier array is filled with zeroes, ie. DRM_FORMAT_MOD_LINEAR. So explicitly tell user-space to not look at it unless the flag is set. Changes in v2 (Daniel): - Mention that handles should be used to compute the number of planes, and only refer to pitches as a fallback. - Reword bit about undefined modifier. Signed-off-by:
