Subject: [Qemu-devel] OpenBios in Sparc can't handle long kernel command lines.
Date: Fri, 22 Mar 2013 00:19:37 -0500 [thread overview]
Message-ID: <1363929577.15703.59@driftwood> (raw)
If I do this:
qemu-system-sparc -nographic -no-reboot -kernel image -hda hda.sqf
-append 'root=/dev/sda rw init=/sbin/init.sh panic=1
PATH=/usr/distcc:/bin:/sbin console=ttyS0 HOST=sparc CPUS=1
DISTCC_HOSTS=10.0.2.2:31322/1 FTP_SERVER=10.0.2.2 FTP_PORT=31307
NATIVE_BUILD=lfs-bootstrap ' -hdb hdb.img -hdc lfs-bootstrap.hdc -m 256
qemu goes:
^[[H^[[JConfiguration device id QEMU version 1 machine id 32
CPUs: 1 x FMI,MB86904
Unhandled Exception 0x00000007
PC = 0xffd07d28 NPC = 0xffd07d2c
Stopping execution
And then hangs. I've never figured out why it clears the screen first
(none of the other targets do), but I _have_ figured out that the
unhandled exception is "kernel command line too long". Because 197
bytes is just too much data for Sparc to cope with.
