Hi, This patch series provides a way for irqchips to define some IRQs as NMIs.
As we hope (maybe) to get the arm64 use case for this into next, this version is simply a rebase of the previous one. Changes since v3[1]: - Rebased on v4.20-rc2 Changes since v2[2]: - Fix ARM build error reported by kbuild bot - Fix documentation warnings reported by kbuild bot Changes since v1[3]: - Rebased to v4.19-rc1 - Fix some coding style issues Changes since RFC[4]: - Rebased to v4.18-rc6 - Remove disable_nmi, one should call disable_nmi_nosync instead - Remove code related to affinity balancing from NMI functions - Require PERCPU configuration for NMIs [1] https://lkml.org/lkml/2018/8/31/173 [2] https://lkml.org/lkml/2018/8/28/661 [3] https://lkml.org/lkml/2018/7/24/321 [4] https://lkml.org/lkml/2018/7/9/768 Cheers, Julien --> Julien Thierry (4): genirq: Provide basic NMI management for interrupt lines genirq: Provide NMI management for percpu_devid interrupts genirq: Provide NMI handlers irqdesc: Add domain handler for NMIs include/linux/interrupt.h | 18 +++ include/linux/irq.h | 10 ++ include/linux/irqdesc.h | 5 + kernel/irq/chip.c | 54 +++++++ kernel/irq/debugfs.c | 6 +- kernel/irq/internals.h | 2 + kernel/irq/irqdesc.c | 35 +++++ kernel/irq/manage.c | 377 +++++++++++++++++++++++++++++++++++++++++++++- 8 files changed, 504 insertions(+), 3 deletions(-) -- 1.9.1
