Bug ID: 93374
Summary: [radeonsi] Tonga (Radeon R9 380) hangs on running
hello world OpenCL program
Product: Mesa
Version: git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: blocker
Priority: medium
Component: Drivers/Gallium/radeonsi
Assignee: dri-devel@lists.freedesktop.org
Reporter: rivanvx@gmail.com
QA Contact: dri-devel@lists.freedesktop.org
I'm running a hello world PyOpenCL program from here:
http://documen.tician.de/pyopencl/ I get the same issue with a different OpenCL
program, e.g. one from bug 93370.
The message shown in the console is the same as bug 93264, but without the VM
line:
amdgpu 0000:01:00.0: GPU fault detected: 147 0x04588402
amdgpu 0000:01:00.0: VM_CONTEXT1_PROECTION_FAULT_ADDR 0x0004008B
amdgpu 0000:01:00.0: VM_CONTEXT1_PROECTION_FAULT_STATUS 0x08084002
The system is unresponsive and one has to do hard reset.
I tried reverting to one commit before c0a189c3792865257c1383f176e5401373ed2270
mentioned in the bug 93264, that is 26ddca196954ccfa697102b46118956ad616073a.
However, this did not fix the problem.

Basically, OpenCL support for VI isn't implemented yet.

What is missing? Can it at least not crash?

--- Comment #3 from EoD <EoD@xmw.de> ---
Is it possible to work around the lock?
I ran into the same issue, when I tried running clpeak (
https://github.com/krrishnarraj/clpeak ) on kernel 4.4.0-rc7 with current
mesa-git and an R9 380X.
kernel: amdgpu 0000:01:00.0: IH ring buffer overflow (0x000C01D0, 0x00000B40,
0x000001E0)
kernel: amdgpu 0000:01:00.0: GPU fault detected: 147 0x05f88802
kernel: amdgpu 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x0004009C
kernel: amdgpu 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0A088002
kernel: VM fault (0x02, vmid 5) at page 262300, read from 'TC9' (0x54433900)
