[Qemu-devel] [PATCH v4 03/10] Process pending work while waiting for initial kick-off in TCG mode

[Jan Kiszka]

When the TCG thread is started but not yet the machine, we wait in
qemu_tcg_cpu_thread_fn on tcg_halt_cond. To allow run_on_cpu already at
this time, we need to process pending request in that loop.
