H A D | hvf.c | bf9bf230 Wed Jun 05 06:25:54 CDT 2024 Phil Dennis-Jordan <phil@philjordan.eu> i386/hvf: In kick_vcpu use hv_vcpu_interrupt to force exit
When interrupting a vCPU thread, this patch actually tells the hypervisor to stop running guest code on that vCPU.
Calling hv_vcpu_interrupt actually forces a vCPU exit, analogously to hv_vcpus_exit on aarch64. Alternatively, if the vCPU thread is not running the VM, it will immediately cause an exit when it attempts to do so.
Previously, hvf_kick_vcpu_thread relied upon hv_vcpu_run returning very frequently, including many spurious exits, which made it less of a problem that nothing was actively done to stop the vCPU thread running guest code. The newer, more efficient hv_vcpu_run_until exits much more rarely, so a true "kick" is needed before switching to that.
