Revert "replay: stop us hanging in rr_wait_io_event"

2024-08-16T13:04:19Z

This reverts commit 1f881ea4a444ef36a8b6907b0b82be4b3af253a2. That commit causes reverse_debugging.py test failures, and does not seem to solve the root cause of the problem x86-64 still hangs in record/replay tests. The problem with short-cutting the iowait that was taken during record phase is that related events will not get consumed at the same points (e.g., reading the clock). A hang with zero icount always seems to be a symptom of an earlier problem that has caused the recording to become out of synch with the execution and consumption of events by replay.

accel/kvm: Introduce kvm_create_and_park_vcpu() helper

2024-07-25T23:21:06Z

There are distinct helpers for creating and parking a KVM vCPU. However, there can be cases where a platform needs to create and immediately park the vCPU during early stages of vcpu init which can later be reused when vcpu thread gets initialized. This would help detect failures with kvm_create_vcpu at an early stage. Suggested-by: Nicholas Piggin Reviewed-by: Nicholas Piggin Signed-off-by: Harsh Prateek Bora Signed-off-by: Nicholas Piggin

accel/kvm: Extract common KVM vCPU {creation,parking} code

2024-07-23T00:15:41Z

KVM vCPU creation is done once during the vCPU realization when Qemu vCPU thread is spawned. This is common to all the architectures as of now. Hot-unplug of vCPU results in destruction of the vCPU object in QOM but the corresponding KVM vCPU object in the Host KVM is not destroyed as KVM doesn't support vCPU removal. Therefore, its representative KVM vCPU object/context in Qemu is parked. Refactor architecture common logic so that some APIs could be reused by vCPU Hotplug code of some architectures likes ARM, Loongson etc. Update new/old APIs with trace events. New APIs qemu_{create,park,unpark}_vcpu() can be externally called. No functional change is intended here.
