Subject: [PATCH V4 0/2] powerpc: add support for ISA v2.07 compat level
Date: Mon, 14 Nov 2016 11:35:06 +1100 [thread overview]
Message-ID: <1479083708-11797-1-git-send-email-sjitindarsingh@gmail.com> (raw)
Version v3.00 of the ISA added a new compat level to the processor
compatibility register (PCR), an ISA v2.07 compatibility mode.
Upstream QEMU already supports this so it may as well go into the kernel
now.
Change Log:
V1 -> V2:
- Reworked logic to set and mask the PCR, no functional change
V2 -> V3:
- Reworked logic again, no functional change
V3 -> V4:
- Added a comment in the first patch to clarify why a 'dummy' PCR v3.00
value is needed
Suraj Jitindar Singh (2):
powerpc: Define new ISA v3.00 logical PVR value and PCR register value
powerpc/kvm: Update kvmppc_set_arch_compat() for ISA v3.00
arch/powerpc/include/asm/reg.h | 11 +++++++++++
arch/powerpc/kvm/book3s_hv.c | 38 +++++++++++++++++++++++---------------
