Done, thanks, Paolo
Paolo, Here's the second batch of KVM/arm64 fixes for 6.14. The most noticeable item here is a rather large rework of our FP/SIMD/SVE/SME handling, mostly removing a bunch of fairly pointless and not-quite-thought-out optimisations. This fixes a bunch of failures reported in the wild, and makes the code far more maintainable. Thanks to Mark Rutland for doing all the hard work. The rest is mostly a bunch of fixes cleanups after the merge window (timers, vgic, pKVM...). Please pull, M. The following changes since commit 0e459810285503fb354537e84049e212c5917c33: KVM: arm64: timer: Don't adjust the EL2 virtual timer offset (2025-02-04 15:10:38 +0000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm.git tags/kvmarm-fixes-6.14-2 for you to fetch changes up to b3aa9283c0c505b5cfd25f7d6cfd720de2adc807: KVM: arm64: vgic: Hoist SGI/PPI alloc from vgic_init() to kvm_create_vgic() (2025-02-13 18:03:54 +0000) ---------------------------------------------------------------- KVM/arm64 fixes for 6.14, take #2 - Large set of fixes for vector handling, specially in the interactions between host and guest state. This fixes a number of bugs affecting actual deployments, and greatly simplifies the FP/SIMD/SVE handling. Thanks to Mark Rutland for dealing with this thankless task. - Fix an ugly race between vcpu and vgic creation/init, resulting in unexpected behaviours. - Fix use of kernel VAs at EL2 when emulating timers with nVHE. - Small set of pKVM improvements and cleanups. ---------------------------------------------------------------- Marc Zyngier (4): KVM: arm64: Fix __pkvm_host_mkyoung_guest() return value KVM: arm64: Convert timer offset VA when accessed in HYP code KVM: arm64: timer: Drop warning on failed interrupt signalling KVM: arm64: vgic: Hoist SGI/PPI alloc from vgic_init() to kvm_create_vgic() Mark Rutland (9): KVM: arm64: Unconditionally save+flush host FPSIMD/SVE/SME state KVM: arm64: Remove host FPSIMD saving for non-protected KVM KVM: arm64: Remove VHE host restore of CPACR_EL1.ZEN KVM: arm64: Remove VHE host restore of CPACR_EL1.SMEN KVM: arm64: Refactor CPTR trap deactivation KVM: arm64: Refactor exit handlers KVM: arm64: Mark some header functions as inline KVM: arm64: Eagerly switch ZCR_EL{1,2} KVM: arm64: Simplify warning in kvm_arch_vcpu_load_fp() Quentin Perret (3): KVM: arm64: Improve error handling from check_host_shared_guest() KVM: arm64: Simplify np-guest hypercalls KVM: arm64: Fix alignment of kvm_hyp_memcache allocations arch/arm64/include/asm/kvm_emulate.h | 42 --------- arch/arm64/include/asm/kvm_host.h | 24 ++---- arch/arm64/kernel/fpsimd.c | 25 ------ arch/arm64/kvm/arch_timer.c | 16 ++-- arch/arm64/kvm/arm.c | 8 -- arch/arm64/kvm/fpsimd.c | 107 ++--------------------- arch/arm64/kvm/hyp/entry.S | 5 ++ arch/arm64/kvm/hyp/include/hyp/switch.h | 148 ++++++++++++++++++++++++-------- arch/arm64/kvm/hyp/nvhe/hyp-main.c | 15 ++-- arch/arm64/kvm/hyp/nvhe/mem_protect.c | 76 ++++++++-------- arch/arm64/kvm/hyp/nvhe/switch.c | 89 +++++++++---------- arch/arm64/kvm/hyp/vhe/switch.c | 33 ++++--- arch/arm64/kvm/vgic/vgic-init.c | 74 ++++++++-------- 13 files changed, 287 insertions(+), 375 deletions(-)
