Title:
AC97 sound card crashes QEMU
Status in QEMU:
Fix Released
Bug description:
The AC97 sound card does not work. It stops QEMU on startup. The cause
appears to be some kind of deadlock.
Steps to reproduce:
Just add -soundhw ac97 to QEMU's arguments. Example: qemu-system-ppc -soundhw ac97
The example above is all it takes to reproduce the problem.
This problem has been observed on Mac OS X and Debian Linux.
I question whether the ac97 support ever worked. It is a file that was
taken from VirtualBox and added to QEMU. I do know that VirtualBox's
support for the ac97 sound card works perfectly.
The exact line of code that stops QEMU in its tracks is located in the
file main-loop.c, in the function os_host_main_loop_wait(), the call
made to qemu_mutex_lock_iothread(). The is where QEMU stops under Mac
OS X.
