| | | | | | | | | | | This patch is the result of an automatic spatch transformation to convert all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.

|/ | | | | | | | | | | | | The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more.

| | | | | | | | | | | | | | | | | | | | | | | This patch corrects a message bug in the via-velocity driver which bothered me for some time. The messages printed during device init look like the following: [ 8.486422] eth%d: set value of parameter Wake On Lan options to 0 ^^! [ 8.487340] eth0: VIA Networking Velocity Family Gigabit Ethernet Adapter Note the unresolved format string. dev->name is unavailable before register_netdev, so use dev_driver_string(&pdev->dev), which is also consistent with other drivers.

* via-velocity: move residual free rx descriptors count register updateFrancois Romieu2008-07-11
| | | | | | | | | | | | | | | | | | | | | Updates of the RBRDU have two different meanings depending on their context: 1. the receiving process has not started - the value which is written into the RBRDU register is supposed to be the free rx descriptors count (rounded to a multiple of 4) 2. the receiving process is running - the value increments the count above (sic) The update is currently issued deep inside the rx replenish chain (see velocity_give_many_rx_descs). Let's propagate enough information to the caller so that the rx replenish functions do not depend on hardware any more. It is needed to perform the Rx/Tx buffers housekeeping when MTU changes.

* via-velocity: remove the bounce buffersFrancois Romieu2008-07-11
| | | | | | | | | | | | | | | | | | | | | | Executive summary: the bounce buffers are in my way - they use something like a 64 * 1500 bytes area of PCI consistent area - they are not resized when the MTU changes - they are used - to hand-pad undersized packets. skb_pad anyone ? - to linearize fragmented skbs whose fragment count goes beyond the 7 fragments hardware limit in order to claim scatter-gather support Actually the SG code is commented out and I wonder if it could not be implemented (ab-)using the large send feature of the chipset since the latter should support some multi-descriptor packet transmitting.

* PCI: Change all drivers to use pci_device->revisionAuke Kok2007-07-11
| | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.

* 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.
