Hi Emily,
the root cause of the hang was found and as far as I know the plan is to
fix this with new RLC firmware.
Please see the internal thread with the hardware guys.
Thanks,
Christian.

Hi Alex and Christian,
Those patches are important for vega10 SRIOV, without this, vega10 run
many games will hang on SRIOV,
how about to add "if (amdgpu_sriov_vf(adev) && adev->asic_type ==
CHIP_VEGA10)" to separate the
bare metal and SRIOV?
Best Wishes,
Emily Deng

drm/amdgpu/gmc9: use amdgpu_ring_emit_reg_write_reg_wait in gpu
tlb flush
Use amdgpu_ring_emit_reg_write_reg_wait. On engines that support
it,
it provides a write and wait in a single packet which avoids a missed
ack if a world switch happens between the request and waiting for the
ack.

Causes my raven1 to lockup on starting X with a gfx ring stall.
I've reverted the patches.
Yeah, you need a specialized firmware version for this which Raven probably
doesn't have.
Anyway the root cause of the issue which should be fixed by this patch set
was found in the meantime, so the whole patch set shouldn't be necessary
any more.
Christian.
