https://bugzilla.kernel.org/show_bug.cgi?id=68301 Bug ID: 68301 Summary: [bisected] Headless OpenCL broken Product: Drivers Version: 2.5 Kernel Version: 3.13 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: niels_ole@xxxxxxxxxxxxxxxxxxxxx Regression: No Created attachment 121331 --> https://bugzilla.kernel.org/attachment.cgi?id=121331&action=edit dmesg output Since 10ebc0bc09344ab6310309169efc73dfe6c23d72, headless OpenCL is broken on my university's Radeon S7000 unless I pass "radeon.runpm=0". The first OpenCL program after a reboot seems to work, but all after that output an error similar to the following: radeon: Failed to allocate virtual address for buffer: radeon: size : 4352 bytes radeon: alignment : 4096 bytes radeon: domains : 4 radeon: va : 0x0000000000800000 radeon: Failed to allocate virtual address for buffer: radeon: size : 4352 bytes radeon: alignment : 4096 bytes radeon: domains : 4 radeon: va : 0x0000000000800000 In dmesg, I can see that some parts of the initialization routine are repeated: [ 348.906146] [drm] probing gen 2 caps for device 8086:151 = 261ad03/e [ 348.906151] [drm] PCIE gen 3 link speeds already enabled [ 348.909465] [drm] PCIE GART of 1024M enabled (table at 0x0000000000478000). [...] After that, the GPU keeps locking up. I have attached the dmesg output. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
