Jinjie Ruan 916b93f4e8 arm64: smp: Fix missing IPI statistics ... commit 83cfac95c0 ("genirq: Allow interrupts to be excluded from /proc/interrupts") is to avoid IPIs appear twice in /proc/interrupts. But the commit 331a1b3a83 ("arm64: smp: Add arch support for backtrace using pseudo-NMI") and commit 2f5cd0c7ffde("arm64: kgdb: Implement kgdb_roundup_cpus() to enable pseudo-NMI roundup") set CPU_BACKTRACE and KGDB_ROUNDUP IPIs "IRQ_HIDDEN" flag but not show them in arch_show_interrupts(), which cause the interrupt kstat_irqs accounting is missing in display. Before this patch, CPU_BACKTRACE and KGDB_ROUNDUP IPIs are missing: / # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 11: 466 600 309 332 GICv3 27 Level arch_timer 13: 24 0 0 0 GICv3 33 Level uart-pl011 15: 64 0 0 0 GICv3 78 Edge virtio0 16: 0 0 0 0 GICv3 79 Edge virtio1 17: 0 0 0 0 GICv3 34 Level rtc-pl031 18: 3 3 3 3 GICv3 23 Level arm-pmu 19: 0 0 0 0 9030000.pl061 3 Edge GPIO Key Poweroff IPI0: 7 14 9 26 Rescheduling interrupts IPI1: 354 93 233 255 Function call interrupts IPI2: 0 0 0 0 CPU stop interrupts IPI3: 0 0 0 0 CPU stop (for crash dump) interrupts IPI4: 0 0 0 0 Timer broadcast interrupts IPI5: 1 0 0 0 IRQ work interrupts Err: 0 After this pacth, CPU_BACKTRACE and KGDB_ROUNDUP IPIs are displayed: / # cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 11: 393 281 532 449 GICv3 27 Level arch_timer 13: 15 0 0 0 GICv3 33 Level uart-pl011 15: 64 0 0 0 GICv3 78 Edge virtio0 16: 0 0 0 0 GICv3 79 Edge virtio1 17: 0 0 0 0 GICv3 34 Level rtc-pl031 18: 2 2 2 2 GICv3 23 Level arm-pmu 19: 0 0 0 0 9030000.pl061 3 Edge GPIO Key Poweroff IPI0: 11 19 4 23 Rescheduling interrupts IPI1: 279 347 222 72 Function call interrupts IPI2: 0 0 0 0 CPU stop interrupts IPI3: 0 0 0 0 CPU stop (for crash dump) interrupts IPI4: 0 0 0 0 Timer broadcast interrupts IPI5: 1 0 0 1 IRQ work interrupts IPI6: 0 0 0 0 CPU backtrace interrupts IPI7: 0 0 0 0 KGDB roundup interrupts Err: 0 Fixes: 331a1b3a83 ("arm64: smp: Add arch support for backtrace using pseudo-NMI") Signed-off-by: Jinjie Ruan <ruanjinjie@huawei.com> Suggested-by: Doug Anderson <dianders@chromium.org> Acked-by: Will Deacon <will@kernel.org> Reviewed-by: Douglas Anderson <dianders@chromium.org> Link: https://lore.kernel.org/r/20240620063600.573559-1-ruanjinjie@huawei.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>		2024-07-08 18:05:23 +01:00
