Can you please address Marc's feedback? If we only make things writable a field at a time it's going to take forever to catch up w/ the architecture. https://lore.kernel.org/kvmarm/86zfrpjkt6.wl-maz@kernel.org/

I will update the patch series again with tackling the full register. Thanks, Shaoqin >
In this patch series, we try to make more register fields writable like ID_AA64PFR1_EL1.BT since this can benifit the migration between some of the machines which have different BT values. Changelog: ---------- RFCv1 -> v1: * Fix the compilation error. * Delete the machine specific information and make the description more generable. RFCv1: https://lore.kernel.org/all/20240612023553.127813-1-shahuang@redhat.com/ Shaoqin Huang (2): KVM: arm64: Allow BT field in ID_AA64PFR1_EL1 writable KVM: selftests: aarch64: Add writable test for ID_AA64PFR1_EL1 arch/arm64/kvm/sys_regs.c | 2 +- tools/testing/selftests/kvm/aarch64/set_id_regs.c | 6 ++++++ 2 files changed, 7 insertions(+), 1 deletion(-)
