Apologies, it is a known issue. I was thrown by the bizarre stack trace, but it seems like it just the mmap failure blowing up in spectacular fashion. The ENOSPC issues arises from when we have either exhausted or badly fragmented the (on your system presumably) 32-bits of address space for GTT mappings such that we are no longer able to allocate new ones. I have recently begun to take a similar issue whereby we exhausted the per-process map limit with over 65,000 vma keep open. The solution there of capping the number of cached vma is likely to resolve this problem as well. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
