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(). But it's better than what we had currently. Acked-by: Maciej W. Rozycki <macro@linux-mips.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-12-02[PATCH] PHY: Add support for configuring the PHY connection interfaceAndy Fleming
Most PHYs connect to an ethernet controller over a GMII or MII interface. However, a growing number are connected over different interfaces, such as RGMII or SGMII. The ethernet driver will tell the PHY what type of connection it is by setting it manually, or passing it in through phy_connect (or phy_attach). Changes include: * Updates to documentation * Updates to PHY Lib consumers * Changes to PHY Lib to add interface support * Some minor changes to whitespace in phy.h * gianfar driver now detects interface and passes appropriate value to PHY Lib Signed-off-by: Andrew Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2006-12-02[PATCH] Fixed a number of bugs in the PHY LayerAndy Fleming
* genphy_update_link is now exported * Added a fix from ncase@xes-inc.com which changes forcing so it only updates the link. Otherwise, it never tries the lower values, since it is always overwriting the speed/duplex values with the current ones, rather than the intended ones. * Fixed a bug where bringing up a PHY with no link caused it to timeout, and enter forcing mode. Once in forcing mode, plugging in the link didn't autonegotiate. Now the AN state detects the lack of link, and enters the NO_LINK state. AN only times out if the link is up and AN fails * Cleaned up the PHY_AN case, reducing one level of indentation for the timeout code. Signed-off-by: Jeff Garzik <jeff@garzik.org>
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.

Adds a phy_mask field to struct mii_bus and uses it. This field indicates each phy address to be ignored when probing the mdio bus. This support is needed for the fs_enet and ibm_emac drivers to be converted to the generic phy layer among other drivers. Many systems lock up on probing certain phy addresses or probing doesn't return 0xffff when nothing is found at the address. A new driver I'm working on also makes use of this mask.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work.
