--- Comment #1 from Christoph Haag <haagch@frickel.club> ---
Some information in case someone tries to reproduce it.
I applied this patch additionally to the revert:
https://bugs.freedesktop.org/show_bug.cgi?id=80880#c10
Many demos work now. But the Cave Demo does not work, it hangs the GPU.
I can not reproduce the original bug I posted here anymore with the patch, just
the hang. It looks like this:
ring 0 stalled for more than 10146msec
GPU lockup (waiting for 0x000000000000a921 last fence id 0x000000000000a920 on
ring 0)
failed to get a new IB (-35)
Saved 205 dwords of commands on ring 0.
GPU softreset: 0x0000004D
GRBM_STATUS = 0xE7DE5028
GRBM_STATUS_SE0 = 0xEF800002
GRBM_STATUS_SE1 = 0xEFC00002
SRBM_STATUS = 0x200000C0
SRBM_STATUS2 = 0x00000000
R_008674_CP_STALLED_STAT1 = 0x00000000
R_008678_CP_STALLED_STAT2 = 0x00010800
R_00867C_CP_BUSY_STAT = 0x00408006
R_008680_CP_STAT = 0x84038647
R_00D034_DMA_STATUS_REG = 0x44C83146
R_00D834_DMA_STATUS_REG = 0x44C83D57
VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000
VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x00000000
GRBM_SOFT_RESET=0x0000DDFF
SRBM_SOFT_RESET=0x00100100
GRBM_STATUS = 0x00003028
GRBM_STATUS_SE0 = 0x00000006
GRBM_STATUS_SE1 = 0x00000006
SRBM_STATUS = 0x200000C0
SRBM_STATUS2 = 0x00000000
R_008674_CP_STALLED_STAT1 = 0x00000000
R_008678_CP_STALLED_STAT2 = 0x00000000
R_00867C_CP_BUSY_STAT = 0x00000000
R_008680_CP_STAT = 0x00000000
R_00D034_DMA_STATUS_REG = 0x44C83D57
R_00D834_DMA_STATUS_REG = 0x44C83D57
GPU reset succeeded, trying to resume
I'll leave this bug report open, because I have no idea if this bug will
reappear once the hang is fixed.
