Currently, the firmware table is parsed by the virtual timer code in order to retrieve the virtual timer interrupt. However, this is already done by the arch timer driver. To avoid code duplication, extend arch_timer_kvm_info to get the virtual IRQ. Note that the KVM code will be modified in a subsequent patch.

Changes in v3: - Move the KVM changes into a separate patch and rename the patch - Move the initialization of the virtual_irq into arch_timer_common_init --- drivers/clocksource/arm_arch_timer.c | 2 ++ include/clocksource/arm_arch_timer.h | 1 + 2 files changed, 3 insertions(+) -- 1.9.1 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
