[RFC 4/5] serial: amba-pl011: Enable NMI aware uart port

Allow serial device interrupt to be requested as an NMI during initialization in polling mode. If the irqchip doesn't support serial device interrupt as an NMI then fallback to it being as a normal IRQ. Currently this NMI aware uart port only supports NMI driven programmed IO operation whereas

[RFC 2/5] serial: core: Add framework to allow NMI aware serial drivers

Add NMI framework APIs in serial core which can be leveraged by serial drivers to have NMI driven serial transfers. These APIs are kept under CONFIG_CONSOLE_POLL as currently kgdb initializing uart in polling mode is the only known user to enable NMI driven serial port. The general idea is to

[RFC 0/5] Introduce NMI aware serial drivers

Make it possible for UARTs to trigger magic sysrq from an NMI. With the advent of pseudo NMIs on arm64 it became quite generic to request serial device interrupt as an NMI rather than IRQ. And having NMI driven serial RX will allow us to trigger magic sysrq as an NMI and hence drop into kernel

[RFC 5/5] serial: Remove KGDB NMI serial driver

This driver provided a special ttyNMI0 port to enable NMI debugging capabilities for kgdb but it remained in silos with the serial core/drivers which made it a bit odd to enable using serial device interrupt and hence remained unused. But now with the serial core/drivers becoming NMI aware which

[RFC 3/5] serial: amba-pl011: Re-order APIs definition

A future patch will need to call pl011_hwinit() and pl011_enable_interrupts() before they are currently defined. Move them closer to the front of the file. There is no change in the implementation of either function. Signed-off-by: Sumit Garg --- drivers/tty/serial/amba-pl011.c | 148

[RFC 1/5] tty/sysrq: Make sysrq handler NMI aware

In a future patch we will add support to the serial core to make it possible to trigger a magic sysrq from an NMI context. Prepare for this by marking some sysrq actions as NMI safe. Safe actions will be allowed to run from NMI context whilst that cannot run from an NMI will be queued as irq_work
