[Qemu-devel] [QEMU-PPC] [PATCH 02/13] target/ppc: Work [S]PURR implementation and add HV support

2019-05-02 Thread Suraj Jitindar Singh
The Processor Utilisation of Resources Register (PURR) and Scaled Processor Utilisation of Resources Register (SPURR) provide an estimate of the resources used by the thread, present on POWER7 and later processors. Currently the [S]PURR registers simply count at the rate of the timebase.
