System: NetBSD o2 4.99.17 NetBSD 4.99.17 (GENERIC32_IP3x) #269: Mon Apr 16 20:28:01 EDT 2007 jmcneill@ptichka.invisible.ca:/Users/jmcneill/NetBSD/src/sys/arch/sgimips/compile/obj/GENERIC32_IP3x sgimips
Architecture: mipseb
Machine: sgimips
>Description:
bus_dmamem_mmap on NetBSD/mips and NetBSD/sgimips returns a cached
address even if the BUS_DMA_COHERENT hint is specified. This makes it
difficult to use eg. system-allocated memory with XFree86 wsfb, as
is the case with sgimips crmfb(4)
>How-To-Repeat:
Boot NetBSD/sgimips -current on an O2 and startx.
>Fix:
Unknown.
