Module Name: src Committed By: sevan Date: Fri Feb 23 02:54:56 UTC 2018
Modified Files: src/sys/arch/macppc/conf: GENERIC MAMBO POWERMAC POWERMAC_G5 src/sys/arch/powerpc/oea: ofw_rascons.c Log Message: Remove OFB_ENABLE_CACHE from <macallan> "it is outdated, genfb and friends don't need or use it, and it makes no sense on accelerated drivers either. It tries to BAT-map the framebuffer cacheable, which works on most macs but makes a few models lock up. Genfb doesn't have that problem and is faster too."
