Hi!
I just played with qemu svn again on FreeBSD (experimental port
update here:
http://people.freebsd.org/~nox/qemu/qemu-devel-20080823.patch
), and noticed a few things:
1. at least umass became slower, down from more than 1 MB/s to little
over 200 KB/s on one box here, emulated images (`usb_add disk:...') were
even more slow.
2, -vmwarevga seems to be broken with -kernel-kqemu (at least for linux
guests, it crashes the guest's xserver), and causes qemu to hang in
vmsvga_fifo_run without -kernel-kqemu sometimes (it never finds the end of
the fifo, and badcmd can also be reached with args not being reset so it
goobles up (unsigned)-1 fifo entries too.) The following patch at least
stops the hangs, I still get `Unknown command 0x%02x in SVGA command FIFO'
messages probably because the fifo still gets out of sync:
