Re: [RFC PATCH v5 0/3] vfio: platform: return device properties for a platform device

In this patch series we want to wrap an already available kernel interface to expose a device property to userspace, in order to keep the code lighter on the userspace. We need those properties in VFIO as VFIO grants the possibility to develop userspace drivers. The sysfs doesn't seems to be

[PATCH v2 1/2] add hooks for armv8 fp/simd lazy switch

This patch adds hooks to support fp/simd lazy switch. A vcpu flag to track fp/simd state, and flag offset in vcpu structure. Signed-off-by: Mario Smarduch --- arch/arm64/include/asm/kvm_host.h | 3 +++ arch/arm64/kernel/asm-offsets.c | 1 + 2 files changed, 4

[PATCH v2 2/2] enable armv8 fp/simd lazy switch

This patch enables arm64 lazy fp/simd switch. Removes the ARM constraint, and follows the same approach as armv7 version - found here. https://lists.cs.columbia.edu/pipermail/kvmarm/2015-September/016567.html To summarize - provided the guest accesses fp/simd unit we limit number of fp/simd

[PATCH v2 0/2] KVM/arm64: add fp/simd lazy switch support

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
