Fix the issue, you need to make sure you don't have the patch that
disable dma on r6xx ie that line 977-978 & 1061-1062 in radeon_asic.c
.copy = &r600_copy_dma,
.copy_ring_index = R600_RING_TYPE_DMA_INDEX,
It fixes the issue for me. Thanks.
The count is actually the count, not count - 1. The real fix seems to
be that r6xx requires 2 dw aligned transfers. The attached patch
fixes the issue for me.
Catching up with this thread. I reverted the
drm/radeon: use async dma for ttm buffer moves on 6xx-SI
commit id: 2d6cc7296d4ee128ab0fa3b715f0afde511f49c2
Do I need to apply this patch without reverting
Correct. Don't revert anything. Just apply this patch.
