| * net drivers: fix platform driver hotplug/coldplugKay Sievers2008-04-252-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable network platform drivers, to re-enable auto loading. NOTE: didn't change drivers/net/fs_enet/fs_enet-main.c "old binding" support. That looks problematic in the first place (it even uses the ancient "struct device_driver" binding scheme for platform_bus!) and I suspect it will vanish soonish when arch/powerpc rules the world. Also, drivers/net/ne.c would have needed more thought to sort out.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-111-38/+34Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-143-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | 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).

* [PATCH] beginning of 8390 fixes - generic and arm/etherhAl Viro2006-12-021-10/+17
| | | | | | | | | | | | | | | | | | | etherh and a handful of other odd drivers use different macros when building 8390.c. Since we generate a single 8390.o and then link with it, in any config with both oddball and normal 8390-based driver we will end up with breakage in at least one of them. Solution: take most of 8390.c into lib8390.c and have 8390.c, etherh.c and the rest of oddballs #include it. Helper macros are taken from 8390.h to whoever includes lib8390.c. That way odd drivers get separate instances of compiled 8390 stuff and stop stepping on each other's toes. 8390.h gets cleaned up - we don't have the cascade of ifdefs in there and are left with the stuff that can be used by any 8390-based driver. Current problems are exactly because of that cascade - we attempt to choose the set of helpers by looking at config and that, of course, doesn't work well when we have several sets needed by various drivers in our config.

| | | | | | | | | | | | | | | | | | Ray Lehtiniemi reported that an incoming UDP packet flood can lock up the ep93xx ethernet driver. Herbert Valerio Riedel noted that due to the way ep93xx_eth manages the RX/TXstatus rings, it cannot distinguish a full ring from an empty one, and correctly suggested that this was likely to be causing this lockup to occur. Instead of looking at the hardware's RX/TXstatus ring write pointers to determine when to stop reading from those rings, we should just check every individual RX/TXstatus descriptor's valid bit instead, since there is no other way to distinguish an empty ring from a full ring, and if there is a descriptor waiting, we take the hit of reading the descriptor from memory anyway.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-055-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 more preparation for adding support for the new Atmel AT91SAM9 processors. Changes include: - Replace AT91_BASE_* with AT91RM9200_BASE_* - Replace AT91_ID_* with AT91RM9200_ID_* - ROM, SRAM and UHP address definitions moved to at91rm9200.h. - The raw AT91_P[ABCD]_* definitions are now depreciated in favour of the GPIO API.

* [NET]: Avoid allocating skb in skb_padHerbert Xu2006-06-232-4/+2Star
| | | | | | | | | | | | | | | | | | | | First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| | | | | | | | | | | | | | | | Moved global ether_clk variable into controller data structure. Patch from David Brownell. Davicom 9161 PHY was being incorrectly displayed as "9196". Patch from Brian Stafford. clk_get() doesn't return NULL on error, so the return value needs to be tested with IS_ERR(). Whitespace cleanup.
