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. Patch-12 adds an option to randomly migrate the vCPUs to different physical CPUs across the system. The bug for the fix provided by Marc with commit 3134cc8beb69d0d ("KVM: arm64: vgic: Resample HW pending state on deactivation") was discovered using arch_timer test with vCPU migrations. Since the test heavily depends on interrupts, patch-10 adds a host library to setup ARM Generic Interrupt Controller v3 (GICv3). This includes creating a vGIC device, setting up distributor and redistributor attributes, and mapping the guest physical addresses. Symmetrical to this, patch-9 adds a guest library to talk to the vGIC, which includes initializing the controller, enabling/disabling the interrupts, and so on. 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 8). The patch series, specifically the library support, is derived from the kvm-unit-tests and the kernel itself. Regards, Raghavendra v2 -> v3: - Addressed the comments from Ricardo regarding moving the vGIC host support for selftests to its own library. - Added an option (-m) to migrate the guest vCPUs to physical CPUs in the system. 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'.
