On the FRV arch, removing the regs parameter\nfrom all the genirq function results in a 20% speed up of the IRQ exit path\n(ie: from leaving timer_interrupt() to leaving do_IRQ()).\n\nWhere appropriate, an arch may override the generic storage facility and do\nsomething different with the variable. On FRV, for instance, the address is\nmaintained in GR28 at all times inside the kernel as part of general exception\nhandling.\n\nHaving looked over the code, it appears that the parameter may be handed down\nthrough up to twenty or so layers of functions. Consider a USB character\ndevice attached to a USB hub, attached to a USB controller that posts its\ninterrupts through a cascaded auxiliary interrupt controller. A character\ndevice driver may want to pass regs to the sysrq handler through the input\nlayer which adds another few layers of parameter passing.\n\nI\u0027ve build this code with allyesconfig for x86_64 and i386.

Mostly the changes should be relatively easy.\nTake do_IRQ(), store the regs pointer at the beginning, saving the old one:\n\n\tstruct pt_regs *old_regs \u003d set_irq_regs(regs);\n\nAnd put the old one back at the end:\n\n\tset_irq_regs(old_regs);\n\nDon\u0027t pass regs through to generic_handle_irq() or __do_IRQ().\n\nIn timer_interrupt(), this sort of change will be necessary:\n\n\t-\tupdate_process_times(user_mode(regs));\n\t-\tprofile_tick(CPU_PROFILING, regs);\n\t+\tupdate_process_times(user_mode(get_irq_regs()));\n\t+\tprofile_tick(CPU_PROFILING);\n\nI\u0027d like to move update_process_times()\u0027s use of get_irq_regs() into itself,\nexcept that i386, alone of the archs, uses something other than user_mode().\n\nSome notes on the interrupt handling in the drivers:\n\n (*) input_dev() is now gone entirely. The regs pointer is no longer stored in\n the input_dev struct.\n\n (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.

The alloctor also suffers from it\u0027s very\nbackwards nature as it has tied things together that should have no\ndependencies.\n\nTo solve the basic dynamic irq allocation problem two new architecture\nspecific functions are added: create_irq and destroy_irq.\n\ncreate_irq takes no input and returns an unused irq number, that won\u0027t be\nreused until it is returned to the free poll with destroy_irq.

The two big issues I address are an artificially\nsmall cap on the number of irqs, and that MSI assumes vector \u003d\u003d irq. My\nprimary focus is on x86_64 but I have touched other architectures where\nnecessary to keep them from breaking.\n\n- To increase the number of irqs I modify the code to look at the (cpu,\n vector) pair instead of just looking at the vector.\n\n With a large number of irqs available systems with a large irq count no\n longer need to compress their irq numbers to fit. Removing a lot of brittle\n special cases.\n\n For acpi guys the result is that irq \u003d\u003d gsi.\n\n- Addressing the fact that MSI assumes irq \u003d\u003d vector takes a few more\n patches. But suffice it to say when I am done none of the generic irq code\n even knows what a vector is.\n\nIn quick testing on a large Unisys x86_64 machine we stumbled over at least\none driver that assumed that NR_IRQS could always fit into an 8 bit number.\nThis driver is clearly buggy today. But this has become a class of bugs that\nit is now much easier to hit.\n\nThis patch:\n\nThis is a minor space optimization. In practice I don\u0027t think this has any\naffect because of our alignment constraints and the other fields but there is\nnot point in chewing up an uncessary word and since we already read the flag\nfield this should improve the cache hit ratio of the irq handler.\n\nSigned-off-by: Eric W.

genirq: rename desc-\u003ehandler to desc-\u003echip\n\nThis patch-queue improves the generic IRQ layer to be truly generic, by adding\nvarious abstractions and features to it, without impacting existing\nfunctionality.\n\nWhile the queue can be best described as \"fix and improve everything in the\ngeneric IRQ layer that we could think of\", and thus it consists of many\nsmaller features and lots of cleanups, the one feature that stands out most is\nthe new \u0027irq chip\u0027 abstraction.\n\nThe irq-chip abstraction is about describing and coding and IRQ controller\ndriver by mapping its raw hardware capabilities [and quirks, if needed] in a\nstraightforward way, without having to think about \"IRQ flow\"\n(level/edge/etc.) type of details.\n\nThis stands in contrast with the current \u0027irq-type\u0027 model of genirq\narchitectures, which \u0027mixes\u0027 raw hardware capabilities with \u0027flow\u0027 details.\nThe patchset supports both types of irq controller designs at once, and\nconverts i386 and x86_64 to the new irq-chip design.\n\nAs a bonus side-effect of the irq-chip approach, chained interrupt controllers\n(master/slave PIC constructs, etc.) are now supported by design as well.\n\nThe end result of this patchset intends to be simpler architecture-level code\nand more consolidation between architectures.\n\nWe reused many bits of code and many concepts from Russell King\u0027s ARM IRQ\nlayer, the merging of which was one of the motivations for this patchset.\n\nThis patch:\n\nrename desc-\u003ehandler to desc-\u003echip.\n\nOriginally i did not want to do this, because it\u0027s a big patch. But having\nboth \"desc-\u003ehandler\", \"desc-\u003ehandle_irq\" and \"action-\u003ehandler\" caused a\nlarge degree of confusion and made the code appear alot less clean than it\ntruly is.\n\nI have also attempted a dual approach as well by introducing a\ndesc-\u003echip alias - but that just wasnt robust enough and broke\nfrequently.\n\nSo lets get over with this quickly. The conversion was done automatically\nvia scripts and converts all the code in the kernel.\n\nThis renaming patch is the first one amongst the patches, so that the\nremaining patches can stay flexible and can be merged and split up\nwithout having some big monolithic patch act as a merge barrier.\n\n[akpm@osdl.org: build fix]\n[akpm@osdl.org: another build fix]\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "908dcecda1d18803b5823f30e6c47d2882dc0cf1", "tree": "2e40b7484baa65af9aa4460ae958d445725f484f", "parents": [ "a5d6839b75ca4a29b5e0a5595914a8715e8f746d" ], "author": { "name": "Jan Beulich", "email": "jbeulich@novell.com", "time": "Fri Jun 23 02:06:00 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jun 23 07:43:08 2006 -0700" }, "message": "[PATCH] adjust handle_IRR_event() return type\n\nCorrect the return type of handle_IRQ_event() (inconsistency noticed during\nXen development), and remove redundant declarations.
