KVM: x86: Add a common TSC scaling function

2015-11-10T11:06:15Z

VMX and SVM calculate the TSC scaling ratio in a similar logic, so this patch generalizes it to a common TSC scaling function. Signed-off-by: Haozhong Zhang [Inline the multiplication and shift steps into mul_u64_u64_shr. Remove BUG_ON. - Paolo] Signed-off-by: Paolo Bonzini

KVM: x86: move kvm_set_irq_inatomic to legacy device assignment

2015-11-04T15:24:36Z

The function is not used outside device assignment, and kvm_arch_set_irq_inatomic has a different prototype. Move it here and make it static to avoid confusion. Reviewed-by: Radim Krčmář Signed-off-by: Paolo Bonzini

KVM: x86: merge kvm_arch_set_irq with kvm_set_msi_inatomic

2015-11-04T15:24:35Z

We do not want to do too much work in atomic context, in particular not walking all the VCPUs of the virtual machine. So we want to distinguish the architecture-specific injection function for irqfd from kvm_set_msi. Since it's still empty, reuse the newly added kvm_arch_set_irq and rename it to kvm_arch_set_irq_inatomic. Reviewed-by: Radim Krčmář Signed-off-by: Paolo Bonzini

Merge tag 'kvm-arm-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2015-11-04T15:24:17Z

KVM/ARM Changes for v4.4-rc1 Includes a number of fixes for the arch-timer, introducing proper level-triggered semantics for the arch-timers, a series of patches to synchronously halt a guest (prerequisite for IRQ forwarding), some tracepoint improvements, a tweak for the EL2 panic handlers, some more VGIC cleanups getting rid of redundant state, and finally a stylistic change that gets rid of some ctags warnings.

KVM: Add kvm_arch_vcpu_{un}blocking callbacks

2015-10-22T21:01:41Z

Some times it is useful for architecture implementations of KVM to know when the VCPU thread is about to block or when it comes back from blocking (arm/arm64 needs to know this to properly implement timers, for example). Therefore provide a generic architecture callback function in line with what we do elsewhere for KVM generic-arch interactions. Reviewed-by: Marc Zyngier Signed-off-by: Christoffer Dall

kvm/eventfd: add arch-specific set_irq

2015-10-16T08:34:29Z

Allow for arch-specific interrupt types to be set. For that, add kvm_arch_set_irq() which takes interrupt type-specific action if it recognizes the interrupt type given, and -EWOULDBLOCK otherwise. The default implementation always returns -EWOULDBLOCK. Signed-off-by: Andrey Smetanin Reviewed-by: Roman Kagan Signed-off-by: Denis V. Lunev CC: Vitaly Kuznetsov CC: "K. Y.
