Bellamy <bellamy.beau@gmail.com> --- When unbinding the radeon driver from a second GPU in order to bind to the vfio-pci driver (so it can be used on a virtual machine), the linux kernel will display several warnings. It looks like some resources may be double-freed. The GPU will otherwise work flawlessly in the VM with full acceleration on the stock AMD windows drivers. This actually shows up on all kernels that I've tried: 4.1.0, 3.19, 3.18, etc. I'm not sure it's related, but the first GPU when running X on the host will have some difficulties getting OpenGL working (I have a routine that involves a dance with glxgears and firefox) and will work for some time and then take the entire system down hard. If I avoid anything OpenGL/DRM, the system will run indefinitely. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/dri-devel ^ permalink raw reply [flat|nested] 4+ messages in thread
