[Qemu-devel] [RFC PATCH V7 19/19] target-arm/psci.c: wake up sleeping CPUs (MTTCG)

[fred . konrad]

From: Alex Bennée <address@hidden>

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.
