http://p4web.freebsd.org/@@209863?ac=10 Change 209863 by rwatson@rwatson_cinnamon on 2012/04/19 23:37:19 A bit of late-night kernel hacking: start to make gxemul its own MIPS platform, rather than conflating it with BERI for local testing purposes in the CTSRD project. A gxemul_machdep.c is still required -- and perhaps can be lifted, or simply used, from MALTA. Put gxemul's console driver in its own dev/gxemul tree, in anticipation of future gxemul-specific drivers.
