Priority: medium
Bug ID: 81907
Assignee: dri-devel@lists.freedesktop.org
Summary: Unreal Engine "Effects Cave" Demo crashes in
__memcpy_sse2_unaligned
Severity: normal
Classification: Unclassified
OS: All
Reporter: haagch@frickel.club
Hardware: Other
Status: NEW
Version: git
Component: Drivers/Gallium/radeonsi
Product: Mesa

intel with render nodes, tearfree and DRI3 and I run it with DRI_PRIME=1.
Because of bug 81834 I reverted f4b0ab7afd83c811329211eae8167c9bf238870c.
Now I get this crash in the "Effects Cave" demo of the unreal engine. More
rarely (?) I get bug 80880 instead/first. In other demos (perhaps less complex)
like TappyChicken I always get bug 80880 and never (?) this crash here:
0x00007ffff6a15859 in __memcpy_sse2_unaligned () from /usr/lib/libc.so.6
It seems to run for a few seconds, the music is playing, but the window
contents are black (it seems nothing at all is rendered, sometimes there are
white stripes that do not vanish until it crashes). Then it crashes with the
attached backtrace.
The "binary" struct seem to be always one of the same few. Others are:
binary = {code = 0x7fffb9ced270
"~\n\376\276\t\003\374\276\002\003\002\310\002\002\006\310\001\001", code_size
= 76, config = 0x7fffb9cf1a90 "(\260", config_size = 24, rodata = 0x0,
rodata_size = 0, disassembled = 0}
and
binary = {code = 0x7fffb9f85a10 "~\n\376\276\t", <incomplete sequence
\374\276>, code_size = 4160, config = 0x7fffb9e33840 "(\260", config_size = 24,
rodata = 0x0, rodata_size = 0, disassembled = 0}

--- 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.

Hmm, that one works for me. Only the Elemental and Sci-Fi Hallway demos run
into shader compiler failures and corresponding GPU VM faults for me, no hangs
though.

Right, they're probably separate problems and need to be tracked separately.

--- Comment #3 from Christoph Haag <haagch@frickel.club> ---
Oh, the hang in comment 1 may have been my fault for running it with hyperz.
But without hyperz it hangs too, just less verbosely:
radeon 0000:01:00.0: ring 3 stalled for more than 10016msec
radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000000011c4a last fence id
0x0000000000011b2a on ring 3)
[TTM] Buffer eviction failed

This here doesn't happen anymore with recent mesa git builds either.
Cave Effects demo now runs on my GPU.
