From 7d12e780e003f93433d49ce78cfedf4b4c52adc5 Mon Sep 17 00:00:00 2001 From: David Howells Date: Thu, 5 Oct 2006 14:55:46 +0100 Subject: IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

This is done by a magical formula of FE0MB-8MB*OneBasedChassisNumber+1MB*(RioNodeId-ChassisBase) to find the offset where BIOS puts it. In this formula, OneBasedChassisNumber corresponds to the NUMA node, and rionodeid is always 2 or 3 depending on which chip in the system it is. The problem was that we had an off by one error that caused us to account some busses to the wrong chip and thus give them the wrong address space. Fixes RH bugzilla #203971.

The reason is that some PCI devices may have no PCI interrupt, though they may have interrupts attached via other means. In this case, we shall not use irq->pdev, but device-specific code can later retreive those interrupts instead. Without that patch, Maple and derivatives don't get the right interrupt for the second IDE channel as the linux IDE code fallsback to the PCI irq instead of trying to use the legacy ones for the on-board controller (which has no PCI_INTERRUPT_PIN). Having no PCI IRQ assign to it (as it doesn't request any) fixes it.

This also makes CONFIG_CMDLINE work properly under these conditions. This change adds a test for the existence of the bootargs property. early_init_dt_scan_chosen() tests for a zero length bootargs property in its CONFIG_CMDLINE processing, but the current implementation of of_get_flat_dt_prop() doesn't assign a value to the length when no property is found. Since an automatic variable is used, a stale value from the stack will be used in the test.

However pci_enable_irq was using a different test in the io_apic_assign_irqs path and I missed it :( This patch removes the wrong code so no one hits this problem. This code is only active when a specific set of boot command line parameters is specified which likely explains why no one has notices this earlier. Signed-off-by: Eric W.

Biederman" Date: Sun, 8 Oct 2006 07:47:55 -0600 Subject: [PATCH] x86_64 irq: Allocate a vector across all cpus for genapic_flat. The problem we can't take advantage of lowest priority delivery mode if the vectors are allocated for only one cpu at a time. Nor can we work around hardware that assumes lowest priority delivery mode is always used with several cpus. So this patch introduces the concept of a vector_allocation_domain. A set of cpus that will receive an irq on the same vector. Currently the code for implementing this is placed in the genapic structure so we can vary this depending on how we are using the io_apics. This allows us to restore the previous behaviour of genapic_flat without removing the benefits of having separate vector allocation for large machines. This should also fix the problem report where a hyperthreaded cpu was receving the irq on the wrong hyperthread when in logical delivery mode because the previous behaviour is restored. This patch properly records our allocation of the first 16 irqs to the first 16 available vectors on all cpus. This should be fine but it may run into problems with multiple interrupts at the same interrupt level. Except for some badly maintained comments in the code and the behaviour of the interrupt allocator I have no real understanding of that problem. Signed-off-by: Eric W.

Proposed fix: - make "writer holds lock" distinguishable from "reader tries to grab lock" - have __raw_read_trylock() try to acquire the mutex (in LSB of lock), terminating spin if we see that there's writer holding it. Then do the rest as we do in read_lock(). Thanks to Ingo for discussion...

kill that argument. All but two callers of handle_irq() pass get_irq_regs() as argument; convert the remaining two, kill set_irq_regs() inside handle_irq().

Biederman" Date: Sun, 8 Oct 2006 23:41:59 -0600 Subject: [PATCH] x86_64 irq: Scream but don't die if we receive an unexpected irq Due to code bugs or misbehaving hardware it is possible that we can receive an interrupt that we have not mapped into a linux irq. Calling BUG when that happens is very rude, and if the problem is mild enough prevents anything else from getting done. So instead of calling BUG just scream loudly about the problem and continue running. We don't have enough knowledge to know which interrupt triggered this behavior so we don't acknowledge it. This will likely prevent a recurrence of the problem by jamming up the works with an unacknowledged interrupt. If the interrupt was something important it is quite possible that nothing productive will happen past this point. But it is now at least possible to keep working if the kernel can survive without the interrupt we dropped on the floor. Solutions like irqpoll should generally make dropped irqs non-fatal.

The routine that did this used udelay, which will hang forever when the timebase is stopped, since udelay now spins until the timebase reaches a certain value. The end result is that the kernel would hang when bringing up the second CPU. This fixes it by using a simple loop which just does a fixed number of iterations to generate the delay. These old systems were all clocked at around 200 MHz or so, so a fixed number of iterations is acceptable.
