G'day all,
Have discovered a minor hitch with the non-blocking IO patch.
when changing cdrom devices in the console it dies with
qemu: /home/brad/src/qemu/block.c:425: bdrv_cancel_nonblock_io: Assertion `nbst->state ==
STATE_READ_DONE' failed.
Aborted
I start qemu with qemu -hda test.img -cdrom test.iso
ctrl-alt 2 to change to virtual console
issue a "change cdrom /dev/sr0"
and the above happens. It does not seem to matter from<->to what I am changing
the device.
I'm using a latest CVS version with the dma/nonblocking IO patch added only.
Other than that, it seems to tick along quite fine. I have been using it for days on end now and the
other bonus the non-blocking patch seems to have is qemu when running windows seems to keep better
time. Prior to this patch the clock drift was horrid. I had to install an ntp daemon in windows to
keep it synced to the host, now it's nowhere near as bad.
It would also appear that the non-blocking patch helps the "stalling" problem, where long installs
or tasks would appear to stall until I moved the mouse or sent a packet over the network. But this
is hard to prove, just feels better.
Regards,
Brad
