KVM: PPC: Book3S HV: Add infrastructure to support 2nd DAWR

2021-02-10T03:31:08Z

KVM code assumes single DAWR everywhere. Add code to support 2nd DAWR. DAWR is a hypervisor resource and thus H_SET_MODE hcall is used to set/ unset it. Introduce new case H_SET_MODE_RESOURCE_SET_DAWR1 for 2nd DAWR. Also, KVM will support 2nd DAWR only if CPU_FTR_DAWR1 is set. Signed-off-by: Ravi Bangoria Signed-off-by: Paul Mackerras

KVM: PPC: Book3S HV: Save/restore new PMU registers

2020-07-22T11:56:41Z

Power ISA v3.1 has added new performance monitoring unit (PMU) special purpose registers (SPRs). They are: Monitor Mode Control Register 3 (MMCR3) Sampled Instruction Event Register A (SIER2) Sampled Instruction Event Register B (SIER3) Add support to save/restore these new SPRs while entering/exiting guest. Also include changes to support KVM_REG_PPC_MMCR3/SIER2/SIER3. Add new SPRs to KVM API documentation.
