I've done a bunch of refactoring work on the irq_domain infrastructure. Some of these patches I've posted before, and some our brand new. The goal of this is to greatly simplify how irq_domains work. With this series, instead of there being multiple different types of irq domains, each with different mapping rules, instead there is now only one time of irq_domain that contains both kinds of map; the linear map for irqs below a certain value, and the radix tree for large & sparse irq controllers. As you can see from the following diffstat, the result is a fair bit less code. It should make it easier to understand irqdomains too.
This is the second posting of this series. I've added a couple more patches and dropped an unrelated patch to the versatile irq driver. irqdomain: Relax failure path on setting up mappings irqdomain: Replace LEGACY mapping with LINEAR irqdomain: Add a name field irqdomain: merge linear and tree reverse mappings. irqdomain: Eliminate revmap type irqdomain: Clean up aftermath of irq_domain refactoring irqdomain: Beef up debugfs output irqdomain: Refactor irq_domain_associate_many() irqdomain: remove irq_domain_generate_simple() irqdomain: make irq_linear_revmap() a fast path again irqdomain: Include hwirq number in /proc/interrupts arch/powerpc/platforms/cell/beat_interrupt.c | 2 +- arch/powerpc/platforms/powermac/smp.c | 2 +- arch/x86/kernel/devicetree.c | 4 +- include/linux/irqdomain.h | 142 +++++++------ kernel/irq/generic-chip.c | 6 +- kernel/irq/irqdomain.c | 571 ++++++++++++++++---------------------------------- kernel/irq/proc.c | 2 + 7 files changed, 261 insertions(+), 468 deletions(-) I've pushed this series out to my git server at the following branch: git://git.secretlab.ca/git/linux irqdomain/test It depends on the tip tree's irq/for-arm branch and also Linus' mainline (they need to be merged). The branch above includes both.
