When running with KVM enabled, you can choose between emulating the gic in kernel or user space. If the kernel supports in-kernel virtualization of the interrupt controller, it will default to that. If not, if will default to user space emulation.
Unfortunately when running in user mode gic emulation, we miss out on timer events which are only available from kernel space. This patch set leverages the new kernel/user space pending line synchronization for those timer events. rfc1 -> rfc2: - use local variable for ARM_CPU - remove bear trap - move timer warning to gic device Alexander Graf (2): linux-headers: update ARM: KVM: Enable in-kernel timers with user space gic hw/intc/arm_gic.c | 7 +++++++ include/sysemu/kvm.h | 11 +++++++++++ kvm-all.c | 5 +++++ kvm-stub.c | 5 +++++ linux-headers/asm-arm/kvm.h | 1 + linux-headers/asm-arm64/kvm.h | 1 + linux-headers/linux/kvm.h | 6 ++++++ target-arm/cpu.h | 3 +++ target-arm/kvm.c | 20 ++++++++++++++++++++ 9 files changed, 59 insertions(+) -- 1.8.5.6
