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.

--- Comment #1 from Michel Dänzer michel@daenzer.net --- Basically, OpenCL support for VI isn't implemented yet.

--- Comment #2 from Vedran Miletić rivanvx@gmail.com --- 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.

--- Comment #4 from EoD EoD@xmw.de --- After upgrading to current llvm 3.8-git (2921ff9ffcfd09db1c), the program ran fine:
