Bug ID: 97524
Summary: Invalid sampler settings cause full GPU reset
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: minor
Priority: medium
Component: Drivers/Gallium/radeonsi

Bug repro
Running invalid the following GL settings hangs Mesa pretty badly. Sometime=
s it
says stuck on ring(0)/(3), other times it just hangs; GPU tries to reset but
does a really poor job (at least I can blindly go to tty1 via Ctrl+Alt+F1 t=
hen
reboot via Ctrl+Alt+Supr).
Attachment provided to repro the bug.
What is causing it:
Vertex Shader must use samplerBuffer on binding point 0.
Pixel Shader must use samplerCube on binding point 0.
Bind a TBO to binding point 0.
What happens:
Near full system hang, it becomes really unstable. System can be soft-reboo=
ted
but that's it.
What should happen:
All other GPU drivers I tested with handle this gracefully by raising a
GL_INVALID_OPERATION error and continuing rendering the rest normally.
Version tested: Latest git 22cec6dc5e5a3060bc87f4a92871b4f6eef04632
I'm assigning a low priority since this GL setting combination is invalid to
begin with and I want to believe software isn't shipped like this (though
considering other GPU drivers allow to ignore the problem, I wouldn't be fu=
lly
surprised if there is faulty software out there...); though I believe the
system shouldn't hang because of this.
GL_VERSION =3D 4.3.0.0
GL_VENDOR =3D X.Org
GL_RENDERER =3D Gallium 0.4 on AMD CAPE VERDE (DRM 2.45.0 / 4.7.0-040700-ge=
neric,
LLVM 3.9.0)
uname -r
4.7.0-040700-generic
