2023 -0300 drm/vkms: Fix race-condition between the hrtimer and the atomic commit Currently, it is possible for the composer to be set as enabled and then as disabled without a proper call for the vkms_vblank_simulate(). This is problematic, because the driver would skip one CRC output, causing CRC tests to fail. Therefore, we need to make sure that, for each time the composer is set as enabled, a composer job is added to the queue. In order to provide this guarantee, add a mutex that will lock before the composer is set as enabled and will unlock only after the composer job is added to the queue. This way, we can have a guarantee that the driver won't skip a CRC entry. This race-condition is affecting the IGT test "writeback-check-output", making the test fail and also, leaking writeback framebuffers, as the writeback job is queued, but it is not signaled. This patch avoids both problems. [v2]: * Create a new mutex and keep the spinlock across the atomic commit in order to avoid interrupts that could result in deadlocks.
