Subject: Process pending work while waiting for initial kick-off in TCG mode
X-Git-Tag: v1.1-rc0~289^2~8
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8e564b4ebf472095b7ca5692302c8a3883d99d91;p=thirdparty%2Fqemu.git

Process pending work while waiting for initial kick-off in TCG mode

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.
