Douglas Anderson (2): watchdog/perf: add a weak function for an arch to detect if perf can use NMIs arm64: enable perf events based hard lockup detector Ionela Voinescu (1): cpufreq: add function to get the hardware max frequency Jinjie Ruan (2): irqchip/gic-v3: Fix hard LOCKUP caused by NMI being masked irqchip/gic-v3: Fix a system stall when using pseudo NMI with CONFIG_ARM64_NMI closed Lecopzer Chen (2): watchdog/perf: adapt the watchdog_perf interface for async model arm64: add hw_nmi_get_sample_period for preparation of lockup detector Lorenzo Pieralisi (1): irqchip/gic-v3: Implement FEAT_GICv3_NMI support Mark Brown (11): arm64/booting: Document boot requirements for FEAT_NMI arm64/sysreg: Add definitions for immediate versions of MSR ALLINT arm64/asm: Introduce assembly macros for managing ALLINT arm64/hyp-stub: Enable access to ALLINT arm64/cpufeature: Detect PE support for FEAT_NMI KVM: arm64: Hide FEAT_NMI from guests arm64/nmi: Manage masking for superpriority interrupts along with DAIF arm64/entry: Don't call preempt_schedule_irq() with NMIs masked arm64/irq: Document handling of FEAT_NMI in irqflags.h arm64/nmi: Add handling of superpriority interrupts as NMIs arm64/nmi: Add Kconfig for NMI Mark Rutland (3): irqchip/gic-v3: Ensure pseudo-NMIs have an ISB between ack and handling irqchip/gic-v3: Refactor ISB + EOIR at ack time irqchip/gic-v3: Fix priority mask handling Xiongfeng Wang (1): init: only move down lockup_detector_init() when sdei_watchdog is enabled Yang Yingliang (1): config: enable CONFIG_ARM64_NMI and HARDLOCK_DETECTOR Yicong Yang (3): watchdog: Support watchdog_sdei coexist with existing watchdogs watchdog: Fix call trace when failed to initialize sdei irqchip/gic-v3: Fix one race condition due to NMI withdraw Documentation/arm64/booting.rst | 6 + arch/arm/include/asm/arch_gicv3.h | 7 +- arch/arm64/Kconfig | 20 ++ arch/arm64/configs/tencent.config | 4 +- arch/arm64/include/asm/assembler.h | 34 +++ arch/arm64/include/asm/cpucaps.h | 2 + arch/arm64/include/asm/cpufeature.h | 29 +++ arch/arm64/include/asm/daifflags.h | 20 ++ arch/arm64/include/asm/irqflags.h | 10 + arch/arm64/include/asm/ptrace.h | 2 +- arch/arm64/include/asm/sysreg.h | 26 +++ arch/arm64/kernel/Makefile | 1 + arch/arm64/kernel/cpufeature.c | 64 +++++- arch/arm64/kernel/head.S | 13 ++ arch/arm64/kernel/perf_event.c | 12 +- arch/arm64/kernel/process.c | 9 + arch/arm64/kernel/watchdog_hld.c | 36 ++++ arch/arm64/kernel/watchdog_sdei.c | 8 +- arch/arm64/kvm/hyp/switch.c | 7 + arch/arm64/kvm/sys_regs.c | 2 + drivers/cpufreq/cpufreq.c | 20 ++ drivers/irqchip/irq-gic-v3.c | 314 +++++++++++++++++++++++----- drivers/perf/arm_pmu.c | 5 + include/linux/cpufreq.h | 5 + include/linux/irqchip/arm-gic-v3.h | 4 + include/linux/nmi.h | 11 + include/linux/perf/arm_pmu.h | 2 + init/main.c | 6 +- kernel/watchdog.c | 83 +++++++- kernel/watchdog_hld.c | 12 +- 30 files changed, 702 insertions(+), 72 deletions(-) create mode 100644 arch/arm64/kernel/watchdog_hld.c -- 2.25.1
