Summary: [PATCH] Move upper-limit calculations outside while-loop
Product: xorg
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: enhancement
Priority: low
Component: Driver/nouveau
AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
ReportedBy: seven-FA6nBp6kBxZzu6KWmfFNGwC/G2K4zDHf@public.gmane.org

--> (http://bugs.freedesktop.org/attachment.cgi?id=32020)
Slight improvement in handling upper-boundary for DMA routines.
Attached is a small patch that moves the "line_count" upper limit calculation
outside the while loop in NVAccelUploadM2MF and NVAccelDownloadM2MF. Benefits
are (marginally) faster loops (less instructions, less branch-misses) and
slightly cleaner code (imho).
