This is a kernel out of memory error not a driver bug. The driver is not able to allocate the memory it needs. (In reply to comment #1) > This is a kernel out of memory error not a driver bug. The driver is not > able to allocate the memory it needs. That may be technically true, but order 4 means 16 physically contiguous pages IIUC, which may be difficult for the kernel to provide. We can avoid this by making radeon_vm_get_bos() allocate each list node separately instead of a single large array for all of them. Created attachment 107967 [details]
drm/radeon: Use drm_malloc_ab instead of kmalloc_array
Does this patch fix the problem?
I think this was fixed long ago. |

Also updated Mesa to 10.1.4, glamor a4fbc77 from 2014-03-02. Video card is a Radeon HD 7950 (Tahiti). This problem appears to happen when I am running guest vm's on this system with qemu 2.0.0. My system does have an IOMMU enabled. I don't believe that the error occurs when no guest OS is running on the system.
