2023-05-31Revert "drm/amd/display: Do not set drr on pipe commit"Michel Dänzer
This reverts commit 474f01015ffdb74e01c2eb3584a2822c64e7b2be. Caused a regression: Samsung Odyssey Neo G9, running at 5120x1440@240/VRR, connected to Navi 21 via DisplayPort, blanks and the GPU hangs while starting the Steam game Assetto Corsa Competizione (via Proton 7.0).

2023-05-24drm/amd/display: Have Payload Properly Created After ResumeFangzhi Zuo
At drm suspend sequence, MST dc_sink is removed. When commit cached MST stream back in drm resume sequence, the MST stream payload is not properly created and added into the payload table. After resume, topology change is reprobed by removing existing streams first. That leads to no payload is found in the existing payload table as below error "[drm] ERROR No payload for [MST PORT:] found in mst state" 1. In encoder .atomic_check routine, remove check existance of dc_sink 2. Bypass MST by checking existence of MST root port. dc_link_type cannot differentiate MST port before topology is rediscovered.

2023-05-24drm/amd/display: Fix warning in disabling vblank irqAlan Liu
[Why] During gpu-reset, we toggle vblank irq by calling dc_interrupt_set() instead of amdgpu_irq_get/put() because we don't want to change the irq source's refcount. However, we see the warning when vblank irq is enabled by dc_interrupt_set() during gpu-reset but disabled by amdgpu_irq_put() after gpu-reset. [How] Only in dm_gpureset_toggle_interrupts() we toggle vblank interrupts by calling dc_interrupt_set(). Apart from this we call dm_set_vblank() which uses amdgpu_irq_get/put() to operate vblank irq.

2023-04-26drm/amd/display: fix flickering caused by S/G modeHamza Mahfooz
Currently, on a handful of ASICs. We allow the framebuffer for a given plane to exist in either VRAM or GTT. However, if the plane's new framebuffer is in a different memory domain than it's previous framebuffer, flipping between them can cause the screen to flicker. So, to fix this, don't perform an immediate flip in the aforementioned case.

2023-04-26drm/amd/display: Block optimize on consecutive FAMS enablesWesley Chalmers
[WHY] It is possible to commit state multiple times in rapid succession with FAMS enabled; if each of these commits were to set optimized_required, then the user may see latency. [HOW] fw_based_mclk_switching is currently not used in dc->clk_mgr; use it to track whether the current state has FAMS enabled; if it has, then do not disable FAMS in prepare_bandwidth, and do not set optimized_required.

2023-04-18drm/amdgpu: Fix desktop freezed after gpu-resetAlan Liu
[Why] After gpu-reset, sometimes the driver fails to enable vblank irq, causing flip_done timed out and the desktop freezed. During gpu-reset, we disable and enable vblank irq in dm_suspend() and dm_resume(). Later on in amdgpu_irq_gpu_reset_resume_helper(), we check irqs' refcount and decide to enable or disable the irqs again. However, we have 2 sets of API for controling vblank irq, one is dm_vblank_get/put() and another is amdgpu_irq_get/put(). Each API has its own refcount and flag to store the state of vblank irq, and they are not synchronized. In drm we use the first API to control vblank irq but in amdgpu_irq_gpu_reset_resume_helper() we use the second set of API. The failure happens when vblank irq was enabled by dm_vblank_get() before gpu-reset, we have vblank->enabled true. However, during gpu-reset, in amdgpu_irq_gpu_reset_resume_helper() vblank irq's state checked from amdgpu_irq_update() is DISABLED. So finally it disables vblank irq again. After gpu-reset, if there is a cursor plane commit, the driver will try to enable vblank irq by calling drm_vblank_enable(), but the vblank->enabled is still true, so it fails to turn on vblank irq and causes flip_done can't be completed in vblank irq handler and desktop become freezed. [How] Combining the 2 vblank control APIs by letting drm's API finally calls amdgpu_irq's API, so the irq's refcount and state of both APIs can be synchronized. Also add a check to prevent refcount from being less then 0 in amdgpu_irq_put(). v2: - Add warning in amdgpu_irq_enable() if the irq is already disabled. - Call dc_interrupt_set() in dm_set_vblank() to avoid refcount change if it is in gpu-reset. v3: - Improve commit message and code comments.
