2007-10-10PHYLIB: fix an interrupt loop potential when haltingMaciej W. Rozycki
Ensure the PHY_HALTED state is not entered with the IRQ asserted as it could lead to an interrupt loop. There is a small window in phy_stop(), where the state of the PHY machine indicates it has been halted, but its interrupt output might still be unmasked. If an interrupt goes active right at this moment it will loop as the phy_interrupt() handler exits immediately with IRQ_NONE if the halted state is seen. It is unsafe to extend the phydev spinlock to cover phy_interrupt(). It is safe to swap the order of the actions though as all the competing places to unmask the interrupt output of the PHY, which are phy_change() and phy_timer() are already covered with the lock as is the sequence in question.

2007-10-10PHYLIB: IRQ event workqueue handling fixesMaciej W. Rozycki
Keep track of disable_irq_nosync() invocations and call enable_irq() the right number of times if work has been cancelled that would include them. Now that the call to flush_work_keventd() (problematic because of rtnl_mutex being held) has been replaced by cancel_work_sync() another issue has arisen and been left unresolved. As the MDIO bus cannot be accessed from the interrupt context the PHY interrupt handler uses disable_irq_nosync() to prevent from looping and schedules some work to be done as a softirq, which, apart from handling the state change of the originating PHY, is responsible for reenabling the interrupt. Now if the interrupt line is shared by another device and a call to the softirq handler has been cancelled, that call to enable_irq() never happens and the other device cannot use its interrupt anymore as its stuck disabled. I decided to use a counter rather than a flag because there may be more than one call to phy_change() cancelled in the queue -- a real one and a fake one triggered by free_irq() if DEBUG_SHIRQ is used, if nothing else. Therefore because of its nesting property enable_irq() has to be called the right number of times to match the number disable_irq_nosync() was called and restore the original state. This DEBUG_SHIRQ feature is also the reason why free_irq() has to be called before cancel_work_sync(). While at it I updated the comment about phy_stop_interrupts() being called from `keventd' -- this is no longer relevant as the use of cancel_work_sync() makes such an approach unnecessary. OTOH a similar comment referring to flush_scheduled_work() in phy_stop() still applies as using cancel_work_sync() there would be dangerous. Checked with checkpatch.pl and at the run time (with and without DEBUG_SHIRQ). Signed-off-by: Maciej W.

2007-10-10PHYLIB: Spinlock fixes for softirqsMaciej W. Rozycki
Use spin_lock_bh()/spin_unlock_bh() for the phydev lock throughout as it is used in phy_timer() that is called as a softirq and all the other operations may happen in the user context. There has been a change recently that did such a conversion for some of the operations on the lock, but some have been left intact. Many of them, perhaps all, may be called in the user context and I was able to trigger recursive spinlock acquisition indeed, so I think for the sake of long-term maintenance it is best to convert them all, even if unnecessarily for one or two -- better safe than sorry. Perhaps one in phy_timer() could actually be skipped as only called as a softirq -- I can send an update if that sounds like a good idea. Checked with checkpatch.pl and at the runtime.

2007-07-18Fix Vitesse 824x PHY interrupt ackingAndy Fleming
The Vitesse 824x PHY doesn't allow an interrupt to be cleared if the mask bit for that interrupt isn't set. This means that the PHY Lib's order of handling interrupts (disable, then clear) breaks on this PHY. However, clearing then disabling the interrupt opens up the code for a silly race condition. So rather than change the PHY Lib, we change the Vitesse driver so it always clears interrupts before disabling them. Further, the ack function only clears the interrupt if interrupts are enabled.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2006-12-07Add "run_scheduled_work()" workqueue functionLinus Torvalds
This allows workqueue users to run just their own pending work, rather than wait for the whole workqueue to finish running. This solves the deadlock with networking libphy that was due to other workqueue entries possibly needing a lock that was held by the routine that wanted to flush its own work. It's not wonderful: if you absolutely need to synchronize with the work function having been executed, any user strictly speaking should have its own completion tracking logic, since when we run things explicitly by hand, the generic workqueue layer can no longer help us synchronize. Also, this is strictly only usable for work that has been scheduled without any delayed timers. You can not mix the new interface with schedule_delayed_work().

2006-12-02[PATCH] 2.6.18: sb1250-mac: Phylib IRQ handling fixesMaciej W. Rozycki
This patch fixes a couple of problems discovered with interrupt handling in the phylib core, namely: 1. The driver uses timer and workqueue calls, but does not include <linux/timer.h> nor <linux/workqueue.h>. 2. The driver uses schedule_work() for handling interrupts, but does not make sure any pending work scheduled thus has been completed before driver's structures get freed from memory. This is especially important as interrupts may keep arriving if the line is shared with another PHY. The solution is to ignore phy_interrupt() calls if the reported device has already been halted and calling flush_scheduled_work() from phy_stop_interrupts() (but guarded with current_is_keventd() in case the function has been called through keventd from the MAC device's close call to avoid a deadlock on the netlink lock).

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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 <dhowells@redhat.com> (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
