2010-05-11make SIG_IPI to tcg vcpu thread reliableMarcelo Tosatti1-14/+9
Store tcg loop exit request on a global variable, and transfer it to per-CPUState exit_request after assignment of cpu_single_env. This makes exit request signal from robust. Drop the timedlock hack. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2010-04-07fix 100% cpu utilization when cpu is stoppedPaolo Bonzini1-4/+2
> Hello, > > d6f4ade (disentangle tcg and deadline calculation, 2010-03-10) > introduces following regression(s): > > 100% cpu utilization when QEMU is invoked like: > qemu -S -s ... > > ditto when gdb takes control over the session via gdb-stub > (i.e. the breakpoint is hit or C-c is pressed inside gdb to > interrupt the attached qemu instance) The bug is that env->stopped is not really as comprehensive as it seems to be (and cpu_has_work thinks); it is only valid with iothread basically, and even then it is cleared by reset and it is not set when starting qemu with -S.
