[Qemu-devel] [RFC v1 05/11] target-arm/psci.c: wake up sleeping CPUs

From: Alex Bennée
Subject: [Qemu-devel] [RFC v1 05/11] target-arm/psci.c: wake up sleeping CPUs
Date: Fri, 18 Mar 2016 16:18:46 +0000

Testing with Alexander's bare metal syncronisation tests fails in MTTCG
leaving one CPU spinning forever waiting for the second CPU to wake up.
We simply need to poke the halt_cond once we have processed the PSCI
power on call.
