From bd1de1a0e6eff4bde5ceae969673b85b8446fd6a Mon Sep 17 00:00:00 2001 From: Ravi Bangoria Date: Wed, 16 Dec 2020 16:12:18 +0530 Subject: KVM: PPC: Book3S HV: Add infrastructure to support 2nd DAWR 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.
