* [SK_BUFF]: Introduce skb_copy_to_linear_data{_offset}Arnaldo Carvalho de Melo2007-04-26
| | | | | | | To clearly state the intent of copying to linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <acme@ghostprotocols.net>
* [TCP]: Introduce tcp_hdrlen() and tcp_optlen()Arnaldo Carvalho de Melo2007-04-26
| | | | | | | | | | | | The ip_hdrlen() buddy, created to reduce the number of skb->h.th-> uses and to avoid the longer, open coded equivalent. Ditched a no-op in bnx2 in the process. I wonder if we should have a BUG_ON(skb->h.th->doff < 5) in tcp_optlen()... Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | Correctly detect when TSO should be used on transmit by looking at the skb->gso_size rather than seeing if the frame was larger than our MTU.

* myri10ge: make msi configurable at runtime through sysfsBrice Goglin2006-12-26
| | | | | | | | | | | | Now that IRQ are requested is called on open() and freed on close(), we can safely switch from/to MSI without unloading the module.

* myri10ge: match number of save_state and restoreBrice Goglin2006-12-26
| | | | | | | | | | | | | | Since pci_save_state() pushes MSI and PCIe states on a kind of stack, myri10ge saving the state in advance for parity recovery will push the state again on the stack on suspend. This leads to some memory leak. We add a couple additional calls to save_state and restore_state so that we don't leak anymore. For the future, we are thinking of a better way to recover from parity error without using pci_save_state(). Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve the firmware selection by adding 2 cases where we should use the optimized firmware: * when the actual PCIe link width is lower than 8x. * when the board is plugged to one of the new Intel PCIe chipsets that are known to provide aligned PCIe completions. The patch actually raises two concerns: * We might want to add a generic PCI function to get the PCIe link width since some other drivers (at least ipath) do the same. But we probably do not want to add a new function for every PCIe capability. I will probably look at it and discuss it on linux-pci in the future. * As requested during the submission, the PCI ids of chipsets that are known to provided aligned completion are defined in the myri10ge code. If we keep adding new ones, it might become better to move them to pciids.h. But, this sort of quirk to detect these chipsets are very specific to our NIC, I don't think it is worth moving it to the PCI core until somebody else really needs it.
