           Summary: Add count checking to DMA on Radeon.
           Product: xorg
           Version: CVS_head
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: anholt at FreeBSD.org


We've seen a couple of bugs now involving mistakes in the
BEGIN_RING/ADVANCE_RING counts or mistakes of missing them entirely.  I'd like
to add code to check that what happens inside of BEGIN/ADVANCE pairs matches
expectations.  Attached is a patch which has verified a couple of bugs.  I don't
expect the extra conditionals are expensive enough to warrant conditionalizing
them at compile time.
