Subject: please include KVM: PPC: Book3S HV: Save and restore FSCR in the P9 path
Date: Wed, 7 Jul 2021 23:40:02 -0700	[thread overview]
Message-ID: <20210708064002.hzkjvvzhjticalzm@cerberus> (raw)

Hi,

I'd like to propose the following patch for inclusion into 5.10 LTS

commit: 25edcc50d76c834479d11fcc7de46f3da4d95121
subject: [PATCH] KVM: PPC: Book3S HV: Save and restore FSCR in the P9 path

Without this patch qemu does not work on POWER9 on modern glibc,
so I think it should be included in at least 5.10 lts branch.

I cannot test on older LTS versions unfortunately, only 5.10.

Started Virtual Machine qemu-2-gentoo-ppc64-stable.
Facility 'SCV' unavailable (12), exception at 0x7fff9f81d4b0, MSR=900000000280f033
