Priority: medium Bug ID: 69328 Assignee: dri-devel@lists.freedesktop.org Summary: Recoverable and unrecoverable lockups with opencl-example on trinity APU Severity: normal Classification: Unclassified OS: Linux (All) Reporter: slicksam@gmx.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/DRI/R600 Product: Mesa
Software in use:
Up to date mesa, llvm, clang, libclc, firmware, as of 20130910. Gentoo's Linux 3.11. opencl-example-12905ac620b83713b07ece763ff3c36fb3c2e7e5.
Hardware in use: AMD A8 5600K APU (Radeon HD 7560D, Aruba), 32GB system RAM, Biostar Hi-Fi A85W motherboard.
Steps to reproduce:
Run hello_world program from opencl-example. First run works correctly. Second run either completely locks up the machine or locks up the GPU (which recovers after a short time). Same behavior for other tests - the first test completes and the second causes problems.
This is what the second opencl-example run looks like:
localhost opencl-example-12905ac620b83713b07ece763ff3c36fb3c2e7e5 # ./hello_world There are 1 platforms. There are 1 GPU devices. clCreateContext() succeeded. clCreateCommandQueue() succeeded. clCreateProgramWithSource() suceeded. clBuildProgram() suceeded. clCreateKernel() suceeded. clCreateBuffer() succeeded. clSetKernelArg() succeeded. clEnqueueNDRangeKernel() suceeded. ((( 10 second hang here, or forever if the machine is toast ))) clEnqueueReadBuffer() suceeded. pi = 3.141590
And, here is the dmesg output from the recoverable lockups:
