[Qemu-devel] [PATCH 28/32] PPC: Add clock-frequency export for Mac machines |
Date: |
Sun, 30 Jun 2013 03:45:05 +0200 |
Support in fwcfg has been around for exposure of the clock-frequency
CPU property. OpenBIOS reads it, we just never exposed it.
Since Mac OS X is very picky about its clock frequency values, let's
just take a known good value and always expose that.
