Revision 38145df2


Added by Jan Kiszka about 10 years ago

Trigger exit from cpu_exec_all on pending IO events

Except for timer events, we currently do not leave the loop over all
VCPUs if an IO event was filed. That may cause unexpected IO latencies
under !CONFIG_IOTHREAD in SMP scenarios. Fix it by setting the global
exit_request which breaks the loop.
