mainlining shenanigans
536e2e34bd
When developing new (and therefore buggy) interrupt related code, it can sometimes be useful to inject interrupts without having to rely on a device to actually generate them. This functionnality relies either on the irqchip driver to expose a irq_set_irqchip_state(IRQCHIP_STATE_PENDING) callback, or on the core code to be able to retrigger a (edge-only) interrupt. To use this feature: echo -n trigger > /sys/kernel/debug/irq/irqs/IRQNUM WARNING: This is DANGEROUS, and strictly a debug feature. Do not use it on a production system. Your HW is likely to catch fire, your data to be corrupted, and reporting this will make you look an even bigger fool than the idiot who wrote this patch.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
