Boot-tested under QEMU for Rust x86_64, arm64 and riscv64; built-tested
for loongarch64:
Tested-by: Miguel Ojeda <ojeda@kernel.org>
arm32 builds fine too.
However, on arm64 I am seeing:
arch/arm64/kvm/nested.c:1776:2: error: use of undeclared identifier 'resx'
1776 | resx.res0 = ZCR_ELx_RES0 | GENMASK_ULL(8, 4);
| ^
arch/arm64/kvm/nested.c:1777:2: error: use of undeclared identifier 'resx'
1777 | resx.res1 = ZCR_ELx_RES1;
| ^
arch/arm64/kvm/nested.c:1778:33: error: use of undeclared identifier 'resx'
1778 | set_sysreg_masks(kvm, ZCR_EL2, resx);
| ^
Due to commit 10206eaad1b9 ("KVM: arm64: Correctly cap ZCR_EL2 provided
by a guest hypervisor") here.
`resx` indeed doesn't exist, and it seems like it was added by commits
0879478913dd ("KVM: arm64: Introduce data structure tracking both RES0
and RES1 bits") etc., which are in 7.0, from this series:
https://lore.kernel.org/all/20260202184329.2724080-1-maz@kernel.org/
So either we make a targeted backport or backport some commits, no?
I hope that help!
