netbsd-MALTA on qemu

["Alexander Voropay" <alec%sensi.org@localhost>]

Hi!

 Did anyone try to run netbsd-MALTA on the qemu/MIPS ?

 The current (CVS) qemu emulates MALTA well enough to run MIPS Linux
on this platform.

 Unfortunately there are some troubles with netbsd-MALTA:


1) The current NetBSD/MIPS does not understand MIPS 24K core,
the standart for qemu/MIPS

$ qemu-system-mipsel -M malta -nographic -kernel netbsd-MALTA
panic: CPU type (0x19300) not supported
Terminated

Can someone add a MIPS 24K core support ?



2) It runs with 4Kc core, but hangs very early

$ qemu-system-mipsel -M malta -cpu 4Kc -nographic -kernel netbsd-MALTA
