[Qemu-devel] [PATCH] target/ppc: Set PSSCR_EC on cpu halt to prevent spurious wakeup

2019-05-15 Thread Suraj Jitindar Singh
The processor stop status and control register (PSSCR) is used to control the power saving facilities of the thread. The exit criterion bit (EC) is used to specify whether the thread should be woken by any interrupt (EC == 0) or only an interrupt enabled in the LPCR to wake the thread (EC == 1).
