Meta hardware threads have 2 timers. The background timer (TXTIMER) is used as a free-running time base, and the interrupt timer (TXTIMERI) is used for the timer interrupt. Both counters traditionally count at approximately 1MHz.

In combination with patches coming through Russell's tree, this will finally add full support for the kernel based virtual machine on ARM, which has been awaited for some time now. Further, we now have a separate platform for virtual machines and qemu booting that is used by both Xen and KVM, separating these from the Versatile Express reference implementation. Obviously, this new platform is multiplatform capable so it can be combined with existing machines in the same kernel." * tag 'virt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (38 commits) ARM: arch_timer: include linux/errno.h arm: arch_timer: add missing inline in stub function ARM: KVM: arch_timers: Wire the init code and config option ARM: KVM: arch_timers: Add timer world switch ARM: KVM: arch_timers: Add guest timer core support ARM: KVM: Add VGIC configuration option ARM: KVM: VGIC initialisation code ARM: KVM: VGIC control interface world switch ARM: KVM: VGIC interrupt injection ARM: KVM: vgic: retire queued, disabled interrupts ARM: KVM: VGIC virtual CPU interface management ARM: KVM: VGIC distributor handling ARM: KVM: VGIC accept vcpu and dist base addresses from user space ARM: KVM: Initial VGIC infrastructure code ARM: KVM: Keep track of currently running vcpus KVM: ARM: Introduce KVM_ARM_SET_DEVICE_ADDR ioctl ARM: gic: add __ASSEMBLY__ guard to C definitions ARM: gic: define GICH offsets for VGIC support ARM: gic: add missing distributor defintions ARM: mach-virt: fixup machine descriptor after removal of sys_timer ... 2013-02-11T17:21:44Z Olof Johansson olof@lixom.net 2013-02-11T17:21:44Z urn:sha1:5f48a29f1721736930b7817b430039c1d348dd05 2013-02-05T20:10:18Z Olof Johansson olof@lixom.net 2013-02-05T20:10:18Z urn:sha1:f0390669d13b0a1592fc7906445b4f6c8ec5af23 From Stephen Warren: ARM: tegra: cleanup This pull request contains various cleanup and minor changes to core Tegra code: * Tegra clocksource driver is moved to drivers/clocksource. * Various typos, warning cleanup, statics cleanup, section mismatch fixes, etc. * Various small fixes/cleanups for CPU/hotplug/SMP code.

This patch moves arm64 to use the arch_timer driver, gaining additional functionality in doing so, and removes the (now unused) arm_generic driver. Timer-related hooks specific to arm64 are moved into arch/arm64/kernel/time.c.

This patch factors out the core of the arch_timer driver, so it can be shared with other architectures. A couple of functions are added so that architecture-specific code can interact with the driver without needing to touch its internals. The ARM_ARCH_TIMER config variable is moved out to drivers/clocksource/Kconfig, existing uses in arch/arm are replaced with HAVE_ARM_ARCH_TIMER, which selects it.

We'd rather not pollute <linux/> with a header for each function. Instead, create a single of_clksrc_init() function which will determine which clocksource driver to initialize based on device tree.
