[PATCH 0/2] target/ppc: Fixes for hash MMU for ISA v3.0

Posted by Nicholas Piggin 9 months, 2 weeks ago

This fixes a couple of deficiencies in the v3.0 and later (POWER9, 10)
HPT MMU implementation. With these fixes, KVM is unable to boot hash
guests on powernv9/10 machines. Bare metal hash or pseries machine with
hash works, because VRMA is only used when a real hypervisor is
virtualizing a hash guest's real mode addressing.

Thanks,
Nick

Could please add Fixes tags to your 'fix' patches ? No need to resend
just reply on the mailing list with :

   Fixes: <commit> "subject"

Also for the "target/ppc: Fix pending HDEC when entering PM state" patch.

Thanks,

C.
