drm/amdgpu: set vm_update_mode=0 as default for Sienna Cichlid in SRIOV case

2022-11-10T17:15:34+00:00

[ Upstream commit 65f8682b9aaae20c2cdee993e6fe52374ad513c9 ]

For asic with VF MMIO access protection avoid using CPU for VM table updates.
CPU pagetable updates have issues with HDP flush as VF MMIO access protection
blocks write to mmBIF_BX_DEV0_EPF0_VF0_HDP_MEM_COHERENCY_FLUSH_CNTL register
during sriov runtime.

v3: introduce virtualization capability flag AMDGPU_VF_MMIO_ACCESS_PROTECT
which indicates that VF MMIO write access is not allowed in sriov runtime

drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr()

2022-11-03T14:59:17+00:00

[ Upstream commit 90bfee142af0f0e9d3bec80e7acd5f49b230acf7 ]

If the number of pages from the userptr BO differs from the SG BO then the
allocated memory for the SG table doesn't get freed before returning
-EINVAL, which may lead to a memory leak in some error paths. Fix this by
checking the number of pages before allocating memory for the SG table.

drm/amdgpu: disallow gfxoff until GC IP blocks complete s2idle resume

2022-11-03T14:59:12+00:00

commit d61e1d1d5225a9baeb995bcbdb904f66f70ed87e upstream.

In the S2idle suspend/resume phase the gfxoff is keeping functional so
some IP blocks will be likely to reinitialize at gfxoff entry and that
will result in failing to program GC registers.Therefore, let disallow
gfxoff until AMDGPU IPs reinitialized completely.

drm/amdgpu: fix sdma doorbell init ordering on APUs

2022-10-29T08:12:54+00:00

commit 50b0e4d4da09fa501e722af886f97e60a4f820d6 upstream.

Commit 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
uncovered a bug in amdgpu that required a reordering of the driver
init sequence to avoid accessing a special register on the GPU
before it was properly set up leading to an PCI AER error.  This
reordering uncovered a different hw programming ordering dependency
in some APUs where the SDMA doorbells need to be programmed before
the GFX doorbells. To fix this, move the SDMA doorbell programming
back into the soc15 common code, but use the actual doorbell range
values directly rather than the values stored in the ring structure
since those will not be initialized at this point.

This is a partial revert, but with the doorbell assignment
fixed so the proper doorbell index is set before it's used.

Revert "drm/amdgpu: use dirty framebuffer helper"

2022-10-26T10:34:23+00:00

commit 17d819e2828cacca2e4c909044eb9798ed379cd2 upstream.

This reverts commit 66f99628eb24409cb8feb5061f78283c8b65f820.

Unfortunately, that commit causes performance regressions on non-PSR
setups. So, just revert it until FB_DAMAGE_CLIPS support can be added.

drm/amdgpu: Add amdgpu suspend-resume code path under SRIOV

2022-10-05T08:39:38+00:00

commit 3b7329cf5a767c1be38352d43066012e220ad43c upstream.

- Under SRIOV, we need to send REQ_GPU_FINI to the hypervisor
  during the suspend time. Furthermore, we cannot request a
  mode 1 reset under SRIOV as VF. Therefore, we will skip it
  as it is called in suspend_noirq() function.

- In the resume code path, we need to send REQ_GPU_INIT to the
  hypervisor and also resume PSP IP block under SRIOV.
