Hi, SH4 developers. It turns out that io trap is one of the reason of bad qemu-sh 'r2d' system emulation performance. To avoid this problem, 'noiotrap' kernel command line option is added : http://news.gmane.org/gmane.linux.ports.sh.devel The packaged zImage is available at this URL. http://www.assembla.com/spaces/qemu-sh4/documents/b-tmCWiRmr3PiLeJe5afGb/download/sh-test-0.2.tar.bz2 Hope it helps!
