Bugzilla 6242: [mach64] Use private DMA buffers (only)
https://bugs.freedesktop.org/show_bug.cgi?id=6242 Patch by George Sapountzis: https://bugs.freedesktop.org/attachment.cgi?id=6271 Update to new mach64 DRM 2.0.0 with private DMA buffers. Handle EAGAIN in mach64FireBlitLocked: call drmCommandWrite up to MACH64_TIMEOUT times when EAGAIN is returned. Also handle EAGAIN in mach64FlushVerticesLocked.
