If kvmclock is used, which implies the kernel supports it, register a kvmclock device with the sysbus.

In order to use log_start/log_stop with Xen as well in the vga code, this two operations have been put in CPUPhysMemoryClient. The two new functions cpu_physical_log_start,cpu_physical_log_stop are used in hw/vga.c and replace the kvm_log_start/stop. With this, vga does no longer depends on kvm header.

The number of slots and the location of private ones changed several times in KVM's early days.

Mixing up TCG bits with KVM already led to problems around eflags emulation on x86. Moreover, quite some code that TCG requires on cpu enty/exit is useless for KVM. So dispatch between tcg_cpu_exec and kvm_cpu_exec as early as possible. The core logic of cpu_halted from cpu_exec is added to kvm_arch_process_irqchip_events. Moving away from cpu_exec makes exception_index meaningless for KVM, we can simply pass the exit reason directly (only "EXCP_DEBUG vs. rest" is relevant).

To prepare splitting up KVM and TCG CPU entry/exit, move the debug exception into cpus.c and invoke cpu_handle_debug_exception on return from qemu_cpu_exec. This also allows to clean up the debug request signaling: We can assign the job of informing main-loop to qemu_system_debug_request and stop the calling cpu directly in cpu_handle_debug_exception. That means a debug stop will now only be signaled via debug_requested and not additionally via vmstop_requested.

If the machine is stopped, we should not record two different tsc values upon a save operation. The same problem happens with kvmclock. But kvmclock is taking a different diretion, being now seen as a separate device. Since this is unlikely to happen with the tsc, I am taking the approach here of simply registering a handler for state change, and using a per-CPUState variable that prevents double updates for the TSC.

The reset we issue on KVM_EXIT_SHUTDOWN implies that we should also leave the VCPU loop. As we now check for exit_request which is set by qemu_system_reset_request, this bug is no longer critical.

KVM requires to reenter the kernel after IO exits in order to complete instruction emulation. Failing to do so will leave the kernel state inconsistently behind. To ensure that we will get back ASAP, we issue a self-signal that will cause KVM_RUN to return once the pending operations are completed. We can move kvm_arch_process_irqchip_events out of the inner VCPU loop. The only state that mattered at its old place was a pending INIT request. Catch it in kvm_arch_pre_run and also trigger a self-signal to process the request on next kvm_cpu_exec. This patch also fixes the missing exit_request check in kvm_cpu_exec in the CONFIG_IOTHREAD case.
