2022-06-01tests/kms_hdr: Skip if current & requested BPC doesn't matchBhanuprakash Modem
The "max bpc" property only ensures that the bpc will not go beyond the value set through this property. It does not guarantee that the same bpc will be used for the given mode. If clock/bandwidth constraints permit, the max bpc will be used to show the mode, otherwise the bpc will be reduced. So, if we really want a particular bpc set, we can try reducing the resolution, till we get the bpc that we set in max bpc property. This patch will skip the test, if there is no valid resolution to get the same bpc as set by max_bpc property.

2022-06-01tests/i915: Use correct type for gen parameterKarolina Drobnik
intel_gen is designed to return a big unsigned number for an unknown device. The value is interpreted to be the newest generation possible, and the matching configuration is used. Some functions incorrectly pass the gen value as a signed number, meaning it becomes negative, and the oldest configuration is used instead of the newest one. This leads to GPU hangs in some cases. Update the definition of submit functions in gem_exec_gttfill and gem_softpin, and has_cs_timestamp in gem_ctx_engines to use a correct type for gen parameter.

2022-05-27lib/igt_kms: Set pipe->plane_primary to driver-assigned primary plane when ↵Jessica Zhang
there are multiple possible primary planes Currently, IGT populates pipe->planes using possible_crtcs and assumes that the first primary plane it encounters is the one being actively used by the pipe. This is not always true in cases where there are multiple possible primary planes. This will cause problems whenever IGT calls drmModePageFlip since drmModePageFlip will use the primary plane assigned to the pipe by the driver to perform the page flip [1]. So a mismatch between the primary plane used by IGT and the driver can cause the page flip to fail. To fix this, let's implement a helper method to get the primary plane that's being assigned to the pipe by the driver. We can then call it during igt_display_require() and, if there's a mismatch between pipe->plane_primary and the assigned primary plane's index, we can swap the unused primary plane with the driver-assigned primary plane [1] https://gitlab.freedesktop.org/drm/msm/-/blob/msm-next/drivers/gpu/drm/drm_plane.c#L1234 Changes since v1: - Instead of swapping the pointers of the planes within the array, we can just change the value of pipe->plane_primary. Changes since v2: - Reverted `if (type == DRM_PLANE_TYPE_PRIMARY)` conditional then added a nested if statement to increment num_primary_planes if plane type is primary. Changes since v3: - Created helper method igt_pipe_has_valid_output and added a check for if pipe has valid output before getting the output of a pipe to get the assigned primary plane - Reverted back to using igt_swap to swap the order of the primary planes within the pipe->planes array. Some kms_* tests use igt_output_get_plane(output, 0) to get the primary plane, so this will avoid regressions in those tests. - Updated the plane->index of the primary planes that are being swapped.
