This series actually enables the 2nd DAWR for baremetal and powervm. Kvm guest is still not supported. v1: https://lore.kernel.org/linuxppc-dev/20200602040106.127693-1-ravi.bangoria@linux.ibm.com v1->v2: - Milton reported an issue with one patch in last series[1]. patch #1 fixes that. So patch#1 is new. - Rebased to powerpc/next which now has "Base support for POWER10"[2] series included.
