These patches add support for stolen time functionality. Patch #1 moves the vCPU structure initialisation before the target->init() call to allow early access to the kvm structure from the vCPU during target->init(). Patch #2 modifies the memory layout in arm-common/kvm-arch.h and adds a new MMIO device PVTIME after the RTC region. A new flag is added in kvm-config.h that will be used to control [enable/disable] the pvtime functionality. Patch #3 adds a new command line argument to disable the stolen time functionality(by default is enabled). Changelog since v4: - Propagate a return code from kvm_cpu__setup_pvtime to target->init(vcpu) - Change the order of the patches as the vCPU structure initialisation needs to be done before the PVTIME setup - Return -errno from pvtime__alloc_region(..) - Verify if the system supports KVM_CAP_STEAL_TIME Sebastian Ene (3): aarch64: Populate the vCPU struct before target->init() aarch64: Add stolen time support Add --no-pvtime command line argument Makefile | 1 + arm/aarch64/arm-cpu.c | 2 +- arm/aarch64/include/kvm/kvm-cpu-arch.h | 1 + arm/aarch64/pvtime.c | 98 ++++++++++++++++++++++++++ arm/include/arm-common/kvm-arch.h | 6 +- arm/kvm-cpu.c | 14 ++-- builtin-run.c | 2 + include/kvm/kvm-config.h | 1 + 8 files changed, 116 insertions(+), 9 deletions(-) create mode 100644 arm/aarch64/pvtime.c -- 2.35.1.574.g5d30c73bfb-goog _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/mailman/listinfo/kvmarm
