Hello, The patch series adds a KVM selftest to validate the behavior of ARM's generic timer (patch-9). The test programs the timer IRQs periodically, and for each interrupt, it validates the behaviour against the architecture specifications. The test further provides a command-line interface to configure the number of vCPUs, the period of the timer, and the number of iterations that the test has to run for. Since the test heavily depends on interrupts, the patch series also adds a basic support for ARM Generic Interrupt Controller v3 (GICv3) to the KVM selftest framework (patch-8). Furthermore, additional processor utilities such as accessing the MMIO (via readl/writel), read/write to assembler unsupported registers, basic delay generation, enable/disable local IRQs, and so on, are also introduced that the test/GICv3 takes advantage of (patches 1 through 7). The patch series, specifically the library support, is derived from the kvm-unit-tests and the kernel itself. Regards, Raghavendra v1 -> v2: Addressed comments from Zenghui in include/aarch64/arch_timer.h: - Correct the header description - Remove unnecessary inclusion of linux/sizes.h - Re-arrange CTL_ defines in ascending order - Remove inappropriate 'return' from timer_set_* functions, which returns 'void'.
