           Summary: MCLK and SCLK values miscalculated
           Product: xorg
           Version: CVS_head
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: benh at kernel.crashing.org


In absence of an x86 BIOS, the driver tries to calculate the values for MCLK and
SCLK (since my patches). However, the formula I used fails to take into account
a factor of 2 that has to be applied on one of the deviders, thus causing the
clocks to be underestimated. Enclosed is a fix for it, now, the clocks
calculated by X do match the values advertised by Open Firmware.
