| |
This is version 3 of the genirq patch-queue, against 2.6.17-rc4. This patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. It was written by Thomas Gleixner (who has done most of the heavy-lifting) and me. We reused many bits of code and many concepts from Russell King's ARM IRQ layer.
The ARM architecture has been updated to make use of this improved generic IRQ layer. The new code also enables a cleaner and simpler implementation of lowlevel irq-chip details, chained handlers and other highlevel irq-flow handlers.
The patch-queue consists of 50 individual patches. The queue begins with a handful of cleanups, to make sure we are adding features to a cleaned up codebase. Then come the features that dont need the irq-chip abstractions but are necessary extensions, then comes the core irq-chip abstraction (genirq-core), features that rely on it, and finally, the conversion of the ARM architecture to the new generic IRQ layer.
The full patch-queue can also be downloaded from:

It has been build-tested with allyesconfig, and booted on x86, x86_64 and various ARM platforms. It has been build-tested on all the 50 ARM platforms. Current ARM testing results are at:

Many thanks to the ARM developers who ran the initial patches on their ARM boards and helped tracking down initial migration bugs.
Review suggestions for past iterations of this code from Andrew Morton, Benjamin Herrenschmidt and Christoph Hellwig were incorporated in this version.
