Currently, we only configure and process MCE-related SIGBUS events if CONFIG_IOTHREAD is enabled. The groundwork is laid, we just need to factor out the required handler registration and system configuration.

Found by Stefan Hajnoczi: There is a race in kvm_cpu_exec between checking for exit_request on vcpu entry and timer signals arriving before KVM starts to catch them. Plug it by blocking both timer related signals also on !CONFIG_IOTHREAD and process those via signalfd. As this fix depends on real signalfd support (otherwise the timer signals only kick the compat helper thread, and the main thread hangs), we need to detect the invalid constellation and abort configure.

We do not use the timeout, so drop its logic. As we always poll our signals, we do not need to drop the global lock. Removing those calls allows some further simplifications. Also fix the error processing of sigpending at this chance.

Block SIG_IPI, unblock it during KVM_RUN, just like in io-thread mode. It's unused so far, but this infrastructure will be required for self-IPIs and to process SIGBUS plus, in KVM mode, SIGIO and SIGALRM. As Windows doesn't support signal services, we need to provide a stub for the init function. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

Move {tcg,kvm}_init_ipi and block_io_signals to avoid prototypes, rename the former two to clarify that they deal with more than SIG_IPI. No functional changes - except for the tiny fixup of strerror usage. The forward declaration of sigbus_handler is just temporarily, it will be moved in a succeeding patch. dummy_signal is moved into the !_WIN32 block as we will soon need it also for !CONFIG_IOTHREAD.

First of all, vm_can_run is a misnomer, it actually means "no request pending". Moreover, there is no need to check all pending requests twice, the first time via the inner loop check and then again when actually processing the requests. We can simply remove the inner loop and do the checks directly. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

If there is any pending request that requires us to leave the inner loop if main_loop, makes sure we do this as soon as possible by enforcing non-blocking IO processing. At this change, move variable definitions out of the inner loop to improve readability. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

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. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

A pending vmstop request is also a reason to leave the inner main loop. So far we ignored it, and pending stop requests issued over VCPU threads were simply ignored. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>

If some I/O operation ends up calling qemu_system_reset_request in VCPU context, we record this and inform the io-thread, but we do not terminate the VCPU loop. This can lead to fairly unexpected behavior if the triggering reset operation is supposed to work synchronously. Fix this for TCG (when run in deterministic I/O mode) by setting the VCPU on stop and issuing a cpu_exit. KVM requires some more work on its VCPU loop.

If we call qemu_cpu_kick more than once before the target was able to process the signal, pthread_kill will fail, and qemu will abort. Prevent this by avoiding the redundant signal. This logic can be found in qemu-kvm as well. Signed-off-by: NJan Kiszka <jan.kiszka@siemens.com> Signed-off-by: NMarcelo Tosatti <mtosatti@redhat.com>
