* net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy2009-07-05
| | | | | | | | | | | This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK. Some occurences are missed by the automatic conversion, those will be handled in a seperate patch. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* [NET] smc91x: remove "irq_flags" from "struct smc91x_platdata"Eric Miao2008-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IRQ trigger type can be specified in the IRQ resource definition by IORESOURCE_IRQ_*, we need only one way to specify this. This also fixes the following small issue: To allow dynamic support for multiple platforms, when those relevant macros are not defined for one specific platform, the default case will be: - SMC_DYNAMIC_BUS_CONFIG defined - and SMC_IRQ_FLAGS = IRQF_TRIGGER_RISING While if "irq_flags" is missing when defining the smc91x_platdata, usually as follows: static struct smc91x_platdata xxxx_smc91x_data = { .flags = SMC91X_USE_XXBIT, }; The lp->cfg.irq_flags will always be overriden by the above structure (due to a memcpy), thus rendering lp->cfg.irq_flags to be "0" always. (regardless of the default SMC_IRQ_FLAGS or IORESOURCE_IRQ_* flags) Fixes this by forcing to use IORESOURCE_IRQ_* flags if present, and make the only user of smc91x_platdata.irq_flags (renesas/migor) to use IORESOURCE_IRQ_*.

* net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller2008-06-12
| | | | | | | | | | | | | | | | | | | | | | If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

* net drivers: fix platform driver hotplug/coldplugKay Sievers2008-04-25

* [NET] smc91x: Make smc91x use IRQ resource trigger flagsRussell King2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | smc91x is shared between many different platforms. Each platform needs to specify the interrupt type, and in some cases the irq type depends on more than just the build configuration - it depends on runtime checks. Rather than throwing this code into the SMC_IRQ_FLAGS definition, provide a way for these flags to be passed via the IRQ resource itself. Note that IRQF_TRIGGER_* constants are intentionally defined to correspond with the IORESOURCE_IRQ_* interrupt type flags, in much the same way that the low bits of PCI iomem resources correspond with the BAR flag bits. Also provide a way to configure smc91x to read the IRQ flags from the resource. Once all platforms have been converted over (signified by all definitions of SMC_IRQ_FLAGS being -1) SMC_IRQ_FLAGS should be removed.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] handle errors returned by platform_get_irq*()David Vrabel2006-03-20
| | | | | | | | | platform_get_irq*() now returns on -ENXIO when the resource cannot be found. Ensure all users of platform_get_irq*() handle this error appropriately. Signed-off-by: David Vrabel <dvrabel@arcom.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] IRQ type flagsRussell King2006-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some ARM platforms have the ability to program the interrupt controller to detect various interrupt edges and/or levels. For some platforms, this is critical to setup correctly, particularly those which the setting is dependent on the device. Currently, ARM drivers do (eg) the following: err = request_irq(irq, ...); set_irq_type(irq, IRQT_RISING); However, if the interrupt has previously been programmed to be level sensitive (for whatever reason) then this will cause an interrupt storm. Hence, if we combine set_irq_type() with request_irq(), we can then safely set the type prior to unmasking the interrupt. The unfortunate problem is that in order to support this, these flags need to be visible outside of the ARM architecture - drivers such as smc91x need these flags and they're cross-architecture. Finally, the SA_TRIGGER_* flag passed to request_irq() should reflect the property that the device would like. The IRQ controller code should do its best to select the most appropriate supported mode.

* [PATCH] smc91x: fix bank mismatchRussell King2005-11-18
| | | | | | | | | | | | | | | | | | The smc91x driver relies upon register bank 2 being selected whenever the interrupt handler is called. This isn't always so, especially if we have a link change event during PHY configuration. This results in register bank 0 being selected when the interrupt handler is called, causing the wrong registers to be read for the IRQ mask and status. In turn, this causes us to spin with a permanently asserted IRQ. The patch ensures that smc_phy_configure always exits with register bank 2 selected.

* [PATCH] smc91x: fix one source of spurious interruptsNicolas Pitre2005-11-18
| | | | | | | | | | | | | Not only SMC_ACK_INT(IM_TX_EMPTY_INT) in in smc_hardware_send_pkt) appears to be unnecessary (tested with an SMC91C94 and SMC91C111), but it seems to trigger spurious interrupts on some machines as well. Removed. While at it, let's log any remaining spurious interrupts if any (and clean usage of the max IRQ loop count value).
