2022-07-20soc: a64fx-diag: disable modular buildArnd Bergmann1-1/+1
The NMI infrastructure cannot currently be used in loadable modules: ERROR: modpost: "free_nmi" [drivers/soc/fujitsu/a64fx-diag.ko] undefined! ERROR: modpost: "request_nmi" [drivers/soc/fujitsu/a64fx-diag.ko] undefined! ERROR: modpost: "enable_nmi" [drivers/soc/fujitsu/a64fx-diag.ko] undefined! Disable this for now to make allmodconfig build again. We may revisit this and export those symbols instead in the future.

2022-07-18soc: fujitsu: Add A64FX diagnostic interrupt driverHitomi Hasegawa1-0/+16
Register the NMI/IRQ corresponding to the A64FX's device definition dedicated to diagnostic interrupts, so that when this interrupt is sent using the BMC, it causes a panic. This can be used to obtain a kernel dump. Signed-off-by: Hitomi Hasegawa <[email protected]> Link: https://lore.kernel.org/r/[email protected]' Signed-off-by: Arnd Bergmann <[email protected]>
