This patch series is a followup to the armv7 fp/simd lazy switch implementation, uses similar approach and depends on the series - https://lists.cs.columbia.edu/pipermail/kvmarm/2015-September/016567.html Patches are based on 4.3-rc2 commit 1f93e4a96c91093 Patches are based on earlier arm64 fp/simd optimization work - https://lists.cs.columbia.edu/pipermail/kvmarm/2015-July/015748.html And subsequent fixes by Marc and Christoffer at KVM Forum hackathon to handle 32-bit guest on 64 bit host - https://lists.cs.columbia.edu/pipermail/kvmarm/2015-August/016128.html The patch series have been tested on Foundation Model arm64/arm64 and arm32/arm64. The test program used can be found here https://github.com/mjsmar/arm-arm64-fpsimd-test Launched upto 16 instances on 4-way Guest and another 16 on the host (both cases 1mS sleep), ran overnight. Changes v1->v2: - Tested arm32/arm64 - rebased to 4.3-rc2 - changed a couple register accesses from 64 to 32 bit Mario Smarduch (2): add hooks for armv8 fp/simd lazy switch enable armv8 fp/simd lazy switch arch/arm/kvm/arm.c | 2 -- arch/arm64/include/asm/kvm_asm.h | 1 + arch/arm64/include/asm/kvm_host.h | 3 ++ arch/arm64/kernel/asm-offsets.c | 1 + arch/arm64/kvm/hyp.S | 59 ++++++++++++++++++++++++++------------- 5 files changed, 45 insertions(+), 21 deletions(-) -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
