drm/amdgpu: make damage clips support configurable

2024-02-15T19:18:42Z

We have observed that there are quite a number of PSR-SU panels on the market that are unable to keep up with what user space throws at them, resulting in hangs and random black screens. So, make damage clips support configurable and disable it by default for PSR-SU displays.

drm/amdgpu: skip to program GFXDEC registers for suspend abort

2024-02-07T23:19:04Z

In the suspend abort cases, the gfx power rail doesn't turn off so some GFXDEC registers/CSB can't reset to default value and at this moment reinitialize GFXDEC/CSB will result in an unexpected error. So let skip those program sequence for the suspend abort case. Signed-off-by: Prike Liang Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: move the drm client creation behind drm device registration

2024-01-31T20:33:52Z

This patch is to eliminate interrupt warning below: "[drm] Fence fallback timer expired on ring sdma0.0". An early vm pt clearing job is sent to SDMA ahead of interrupt enabled. And re-locating the drm client creation following after drm_dev_register looks like a more proper flow. v2: wrap the drm client creation Fixes: 1819200166ce ("drm/amdkfd: Export DMABufs from KFD using GEM handles") Signed-off-by: Le Ma Reviewed-by: Felix Kuehling Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amdgpu: revert "Adjust removal control flow for smu v13_0_2"

2024-01-18T21:43:42Z

Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the HW in an active state and is an unbalanced use of the IP callbacks. Using the IP callbacks like this can lead to memory leaks, double free and imbalanced reference counters. Leaving the HW in an active state can lead to DMA accesses to memory now freed by the driver. Both is a complete no-go for driver unload so completely revert the workaround for now. This reverts commit f5c7e7797060255dbc8160734ccc5ad6183c5e04.

drm/amdgpu: Enable tunneling on high-priority compute queues

2023-12-13T20:23:59Z

This improves latency if the GPU is already busy with other work. This is useful for VR compositors that submit highly latency-sensitive compositing work on high-priority compute queues while the GPU is busy rendering the next frame.
