[PATCH 1/2] cpufreq: Make ARM big.LITTLE switcher depend on ARM

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> The patch currently under review to enable ARM cpufreq drivers for ARM64 which is useful due to the large amount of shared IP between ARM and ARM64 SoCs. However the big.LITTLE switcher relies on an architecture interface to build which is not present on ARM64. Add a dependency until that is resolved.

[PATCH v5 00/10] Support VGIC save/restore using device control API

by Christoffer Dall

Implement save/restore of the VGIC state using the newer KVM Device Control API. This requries some number of changes to existing code in addition to actually supporting save/restore of the necessary state. The first patches (01-03) support creating the VGIC using the Device Control API. This change is necessary because there are no other suitable KVM APIs that we can leverage to access the VGIC state from user space and the device control API was crafted exactly for this purpose. Subsequent patches add the missing infrastructure and user space API pieces necessary to actually save and restore the VGIC state. The GIC v2.0 architecture specification already specifies registers that can be used to save and restore the complete VGIC state for suspend/resume purposes on real hardware, and we can reuse this interface for the VGIC. The API is therefore based on the memory-mapped register accesses defined in the specs. See the individual patches for details. The patches are based on kvm-arm-next with the arch timers save/restore patches applied: git://git.linaro.org/people/cdall/linux-kvm-arm.git timer-migrate-v4 This patch series based on the above can be cloned from: git://git.linaro.org/people/cdall/linux-kvm-arm.git vgic-migrate-v5 User space patches for QEMU have also been posted on the list, but an updated version is underway. Tested on Versatile Express TC2. Changelogs in the individual patches.

[PATCH v2] arm: KVM: Don't return PSCI_INVAL if waitqueue is inactive

by Christoffer Dall

The current KVM implementation of PSCI returns INVALID_PARAMETERS if the waitqueue for the corresponding CPU is not active. This does not seem correct, since KVM should not care what the specific thread is doing, for example, user space may not have called KVM_RUN on this VCPU yet or the thread may be busy looping to user space because it received a signal; this is really up to the user space implementation. Instead we should check specifically that the CPU is marked as being turned off, regardless of the VCPU thread state, and if it is, we shall simply clear the pause flag on the CPU and wake up the thread if it happens to be blocked for us. Further, the implementation seems to be racy when executing multiple VCPU threads. There really isn't a reasonable user space programming scheme to ensure all secondary CPUs have reached kvm_vcpu_first_run_init before turning on the boot CPU. Therefore, set the pause flag on the vcpu at VCPU init time (which can reasonably be expected to be completed for all CPUs by user space before running any VCPUs) and clear both this flag and the feature (in case the feature can somehow get set again in the future) and ping the waitqueue on turning on a VCPU using PSCI.
