drm/amdgpu: don't put MQDs in VRAM on ARM | ARM64

2023-11-20T10:57:21+00:00

[ Upstream commit ba0fb4b48c19a2d2380fc16ca4af236a0871d279 ] Issues were reported with commit 1cfb4d612127 ("drm/amdgpu: put MQDs in VRAM") on an ADLINK Ampere Altra Developer Platform (AVA developer platform). Various ARM systems seem to have problems related to PCIe and MMIO access. In this case, I'm not sure if this is specific to the ADLINK platform or ARM in general. Seems to be some coherency issue with VRAM. For now, just don't put MQDs in VRAM on ARM.

drm/amdgpu: Increase IH soft ring size for GFX v9.4.3 dGPU

2023-11-20T10:57:00+00:00

[ Upstream commit bcfb9cee61207b80f37663ffa08c135657a27ad5 ] On GFX v9.4.3 dGPU, applications have random timeout failure when XNACK on, dmesg log has "amdgpu: IH soft ring buffer overflow 0x900, 0x900", because dGPU mode has 272 cam entries. After increasing IH soft ring to 512 entries, no more IH soft ring overflow message and application passed.

drm/amdgpu: Reserve fences for VM update

[ Upstream commit 316baf09d355aec1179981b6dfe28eba50c5ee5b ] In amdgpu_dma_buf_move_notify reserve fences for the page table updates in amdgpu_vm_clear_freed and amdgpu_vm_handle_moved. This fixes a BUG_ON in dma_resv_add_fence when using SDMA for page table updates. Signed-off-by: Felix Kuehling Reviewed-by: Christian König Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

gpu/drm: Eliminate DRM_SCHED_PRIORITY_UNSET

2023-11-08T13:09:01+00:00

[ Upstream commit fa8391ad68c16716e2c06ada397e99ceed2fb647 ] Eliminate DRM_SCHED_PRIORITY_UNSET, value of -2, whose only user was amdgpu. Furthermore, eliminate an index bug, in that when amdgpu boots, it calls drm_sched_entity_init() with DRM_SCHED_PRIORITY_UNSET, which uses it to index sched->sched_rq[].

drm/amdgpu: Unset context priority is now invalid

drm/amd: Disable ASPM for VI w/ all Intel systems

commit 64ffd2f1d00c6235dabe9704bbb0d9ce3e28147f upstream. Originally we were quirking ASPM disabled specifically for VI when used with Alder Lake, but it appears to have problems with Rocket Lake as well. Like we've done in the case of dpm for newer platforms, disable ASPM for all Intel systems.
