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
CPU 0/KVM[2914766]: illegal instruction (4) at 7fff9f81d4b0 nip 7fff9f81d4b0 lr 13e6048e0 code 1 in libc-2.33.so[7fff9f6f0000+200000]
