2008-06-05genirq: Expose default irq affinity mask (take 3)Max Krasnyansky1-0/+5
Current IRQ affinity interface does not provide a way to set affinity for the IRQs that will be allocated/activated in the future. This patch creates /proc/irq/default_smp_affinity that lets users set default affinity mask for the newly allocated IRQs. Changing the default does not affect affinity masks for the currently active IRQs, they have to be changed explicitly. Updated based on Paul J's comments and added some more documentation.

I generally dislike adding optional linux/* includes in asm/* includes - I'm nervous about this causing include loops. However, there's a separate point to be discussed here. That is, what interfaces are expected of every architecture in the kernel. If generic code wants to be able to set the affinity of interrupts, then that needs to become part of the interfaces listed in linux/interrupt.h rather than linux/irq.h. So what I suggest is this approach instead (against Linus' tree of a couple of days ago) - we move irq_set_affinity() and irq_can_set_affinity() to linux/interrupt.h, change the linux/irq.h includes to linux/interrupt.h and include asm/irq_regs.h where needed (asm/irq_regs.h is supposed to be rarely used include since not much touches the stacked parent context registers.)

2007-05-11Add hard_irq_disable()Benjamin Herrenschmidt1-0/+10
Some architectures, like powerpc, implement lazy disabling of interrupts. That means that on those, local_irq_disable() doesn't actually disable interrupts on the CPU, but only sets some per CPU flag which cause them to be disabled only if an interrupt actually occurs. However, in some cases, such as stop_machine, we really want interrupts to be fully disabled. For example, I have code using stop machine to do ECC error injection, used to verify operations of the ECC hardware, that sort of thing. It really needs to make sure that nothing is actually writing to memory while the injection happens. Similar examples can be found in other low level bits and pieces. This patch implements a generic hard_irq_disable() function which is meant to be called -after- local_irq_disable() and ensures that interrupts are fully disabled on that CPU. The default implementation is a nop, though powerpc does already provide an appropriate one.

2007-05-08Add IRQF_IRQPOLL flag (common code)Bernhard Walle1-0/+4
irqpoll is broken on some architectures that don't use the IRQ 0 for the timer interrupt like IA64. This patch adds a IRQF_IRQPOLL flag. Each architecture is handled in a separate pach. As I left the irq == 0 as condition, this should not break existing architectures that use timer_irq == 0 and that I did't address with that patch (because I don't know). This patch: This patch adds a IRQF_IRQPOLL flag that the interrupt registration code could use for the interrupt it wants to use for IRQ polling. Because this must not be the timer interrupt, an additional flag was added instead of re-using the IRQF_TIMER constant. Until all architectures will have an IRQF_IRQPOLL interrupt, irq == 0 will stay as alternative as it should not break anything. Also, note_interrupt() is called on CPU-specific interrupts to be used as interrupt source for IRQ polling.

2007-02-09devres: device resource managementTejun Heo1-0/+6
Implement device resource management, in short, devres. A device driver can allocate arbirary size of devres data which is associated with a release function. On driver detach, release function is invoked on the devres data, then, devres data is freed. devreses are typed by associated release functions. Some devreses are better represented by single instance of the type while others need multiple instances sharing the same release function. Both usages are supported. devreses can be grouped using devres group such that a device driver can easily release acquired resources halfway through initialization or selectively release resources (e.g. resources for port 1 out of 4 ports). This patch adds devres core including documentation and the following managed interfaces. * alloc/free : devm_kzalloc(), devm_kzfree() * IO region : devm_request_region(), devm_release_region() * IRQ : devm_request_irq(), devm_free_irq() * DMA : dmam_alloc_coherent(), dmam_free_coherent(), dmam_declare_coherent_memory(), dmam_pool_create(), dmam_pool_destroy() * PCI : pcim_enable_device(), pcim_pin_device(), pci_is_managed() * iomap : devm_ioport_map(), devm_ioport_unmap(), devm_ioremap(), devm_ioremap_nocache(), devm_iounmap(), pcim_iomap_table(), pcim_iomap(), pcim_iounmap() Signed-off-by: Tejun Heo <[email protected]> Signed-off-by: Jeff Garzik <[email protected]>

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-2/+2
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. Signed-Off-By: David Howells <[email protected]> (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)

These are needed for NE2000; basically NE2000 calls disable_irq and enable_irq as locking against the IRQ handler, but both in cases where interrupts are on and off.

These should be used for locking constructs that know that a particular irq context which is disabled, and which is the only irq-context user of a lock, that it's safe to take the lock in the irq-disabled section without disabling hardirqs.

2006-07-02[PATCH] irq-flags: consolidate flags for request_irqThomas Gleixner1-0/+47
The recent interrupt rework introduced bit value conflicts with sparc. Instead of introducing new architecture flags mess, move the interrupt SA_ flags out of the signal namespace and replace them by interrupt related flags. This allows to remove the obsolete SA_INTERRUPT flag and clean up the bit field values. This patch: Move the interrupt related SA_ flags out of linux/signal.h and rename them to IRQF_ . This moves the interrupt related flags out of the signal namespace and allows to remove the architecture dependencies. SA_INTERRUPT is not needed by userspace and glibc so it can be removed safely. The existing SA_ constants are kept for easy transition and will be removed after a 6 month grace period.

2006-06-23[PATCH] adjust handle_IRR_event() return typeJan Beulich1-20/+1
Correct the return type of handle_IRQ_event() (inconsistency noticed during Xen development), and remove redundant declarations. The return type adjustment required breaking out the definition of irqreturn_t into a separate header, in order to satisfy current include order dependencies.

2006-01-09[SCSI] Kill the SCSI softirq handlingJens Axboe1-1/+0
This patch moves the SCSI softirq handling to the block layer version. There should be no functional changes. Signed-off-by: Jens Axboe <[email protected]>
2006-01-09[BLOCK] ll_rw_blk: Enable out-of-order request completions through softirqJens Axboe1-0/+1
Request completion can be a quite heavy process, since it needs to iterate through the entire request and complete the bio's it holds. This patch adds blk_complete_request() which moves this processing into a dedicated block softirq. Signed-off-by: Jens Axboe <[email protected]>

2005-11-13[PATCH] m68k: thread_info header cleanupAl Viro1-0/+1
a) in smp_lock.h #include of sched.h and spinlock.h moved under #ifdef CONFIG_LOCK_KERNEL. b) interrupt.h now explicitly pulls sched.h (not via smp_lock.h from hardirq.h as it used to) c) in three more places we need changes to compensate for (a) - one place in arch/sparc needs string.h now, hardirq.h needs forward declaration of task_struct and preempt.h needs direct include of thread_info.h. d) thread_info-related helpers in sched.h and thread_info.h put under ifndef __HAVE_THREAD_FUNCTIONS. Obviously safe.

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!
