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

2023-11-20T10:59:33+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/gfx10,11: use memcpy_to/fromio for MQDs

2023-11-20T10:59:33+00:00

[ Upstream commit b3c942bb6c32a8ddc1d52ee6bc24b8cf732dddf4 ]

Since they were moved to VRAM, we need to use the IO
variants of memcpy.

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

2023-11-20T10:59:10+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/amd: Disable ASPM for VI w/ all Intel systems

2023-10-25T13:53:17+00:00

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.

drm/amdgpu: Remove redundant call to priority_is_valid()

2023-10-22T00:27:15+00:00

Remove a redundant call to amdgpu_ctx_priority_is_valid() from
amdgpu_ctx_priority_permit(), which is called from amdgpu_ctx_init() which is
called from amdgpu_ctx_alloc() which is called from amdgpu_ctx_ioctl(), where
we've called amdgpu_ctx_priority_is_valid() already first thing in the
function.

drm/amdgpu: Reserve fences for VM update

2023-10-19T22:56:57+00:00

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.
