Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

genirq: Distangle kernel/irq/handle.c kernel/irq/handle.c has become a dumpground for random code in random order. Split out the irq descriptor management and the dummy irq_chip implementation into separate files. Cleanup the include maze while at it. No code change.

irq: add irq_domain translation infrastructure This patch adds irq_domain infrastructure for translating from hardware irq numbers to linux irqs. This is particularly important for architectures adding device tree support because the current implementation (excluding PowerPC and SPARC) cannot handle translation for more than a single interrupt controller. irq_domain supports device tree translation for any number of interrupt controllers. This patch converts x86, Microblaze, ARM and MIPS to use irq_domain for device tree irq translation. x86 is untested beyond compiling it, irq_domain is enabled for MIPS and Microblaze, but the old behaviour is preserved until the core code is modified to actually register an irq_domain yet. On ARM it works and is required for much of the new ARM device tree board support. PowerPC has /not/ been converted to use this new infrastructure. It is still missing some features before it can replace the virq infrastructure already in powerpc (see documentation on irq_domain_map/unmap for details). Followup patches will add the missing pieces and migrate PowerPC to use irq_domain. SPARC has its own method of managing interrupts from the device tree and is unaffected by this change.

genirq: Introduce generic irq migration for cpu hotunplug ARM and ARM64 have almost identical code for migrating interrupts on cpu hotunplug. Provide a generic version which can be used by both. The new code addresses a shortcoming in the ARM[64] variants which fails to update the affinity change in some cases. The solution for this is to use the core function irq_do_set_affinity() instead of open coding it. [ tglx: Added copyright notice and license boilerplate.

PM: Introduce functions for suspending and resuming device interrupts Introduce helper functions allowing us to prevent device drivers from getting any interrupts (without disabling interrupts on the CPU) during suspend (or hibernation) and to make them start to receive interrupts again during the subsequent resume. These functions make it possible to keep timer interrupts enabled while the "late" suspend and "early" resume callbacks provided by device drivers are being executed. In turn, this allows device drivers' "late" suspend and "early" resume callbacks to sleep, execute ACPI callbacks etc. The functions introduced here will be used to rework the handling of interrupts during suspend (hibernation) and resume. Namely, interrupts will only be disabled on the CPU right before suspending sysdevs, while device drivers will be prevented from receiving interrupts, with the help of the new helper function, before their "late" suspend callbacks run (and analogously during resume).

genirq: Add a helper to spread an affinity mask for MSI/MSI-X vectors This is lifted from the blk-mq code and adopted to use the affinity mask concept just introduced in the irq handling code. It tries to keep the algorithm the same as the one current used by blk-mq, but improvements like assining vectors on a per-node basis instead of just per sibling are possible with this simple move and refactoring.
