[WHY] We return false by default when link training fail at link loss. It will cause we get a fail verified link caps directly. [HOW] Record the highest verified link caps. Use the recorded value as the verified link caps if it is not successful in the last attempt to avoid to use the lowest link setting. Reviewed-by:

[Why] Specific TBT4 dock doesn't send out short HPD to notify source that IRQ event DOWN_REP_MSG_RDY is set. Which violates the spec and cause source can't send out streams to mst sinks. [How] To cover this misbehavior, add an additional polling method to detect DOWN_REP_MSG_RDY is set. HPD driven handling method is still kept.

Despite certain GPUs supporting multiple overlay planes already in AMDGPU, the driver did not expose the zpos property which is required for userspace to take advantage of multiple overlay planes in any meaningful way. The driver was already hooked up to normalized_zpos, but was just missing the exposure of it.

CPU1 CPU2 drm_crtc_vblank_off hrtimer_interrupt grab event_lock (irq disabled) __hrtimer_run_queues grab vbl_lock/vblank_time_block amdgpu_vkms_vblank_simulate amdgpu_vkms_disable_vblank drm_handle_vblank hrtimer_cancel grab dev->event_lock So CPU1 stucks in hrtimer_cancel as timer callback is running endless on current clock base, as that timer queue on CPU2 has no chance to finish it because of failing to hold the lock. So NMI watchdog will throw the errors after its threshold, and all later CPUs are impacted/blocked. So use hrtimer_try_to_cancel to fix this, as disable_vblank callback does not need to wait the handler to finish. And also it's not necessary to check the return value of hrtimer_try_to_cancel, because even if it's -1 which means current timer callback is running, it will be reprogrammed in hrtimer_start with calling enable_vblank to make it works. v2: only re-arm timer when vblank is enabled (Christian) and add a Fixes tag as well v3: drop warn printing (Christian) v4: drop superfluous check of blank->enabled in timer function, as it's guaranteed in drm_handle_vblank (Christian) Fixes: 84ec374b ("drm/amdgpu: create amdgpu_vkms (v4)") Cc: stable@vger.kernel.org Suggested-by:Guchun Chen <guchun.chen@amd.com> Reviewed-by:
