* 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] Remove more unnecessary driver printk'sAndy Gospodarek2006-09-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As I promised last week, here is the first pass at removing all unnecessary printk's that exist in network device drivers currently in promiscuous mode. The duplicate messages are not needed so they have been removed. Some of these drivers are quite old and might not need an update, but I did them all anyway. I am currently auditing the remaining conditional printk's and will send out a patch for those soon. Signed-off-by: Andy Gospodarek <andy@greyhouse.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* [NET]: Avoid allocating skb in skb_padHerbert Xu2006-06-23
| | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] sis190: basic sis191 supportFrancois Romieu2005-09-05
| | | | | | | | | | | | | | The sis191 is the gigabit brother of the sis190. SiS's driver suggests that the register set is backward compatible: this should hopefully give a basic driver. The device should allow the usual features from a modern ethernet adapter (802.1q, SG, Jumbo frames, TSO, checksum offload). So far the relevant register layout is not documented. SiS's driver does not provide these features either (at least not for Linux). Signed-off-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

* [PATCH] sis190: make 10Mbps the default when handling the StationControl ↵Francois Romieu2005-09-05
| | | | | | | | | | | | | | | | register This patch does three things: - widen the access to the StationControl register (note the SIS_W16 versus SIS_W32 change); - default to 10Mbps half duplex when the LPA can not be evaluated (reg31->ctl is identical for both). It can be argued that it makes sense as the lowest common denominator when everything else failed. Btw it works better than the current code. :o) - remove some enums: they do not document anymore.

* [PATCH] sis190: resurrectionFrancois Romieu2005-07-30
Raise the sis190 driver from the dead The driver handles the integrated network device found on SiS 965L chipset. It follows the classical (non-napi) interrupt-driven model and provides minimal ethtool support. The code comes from a heavy cleanup/rewrite of the original code which was removed from the kernel on 14/04/2004. Since the r8169 driver does not work too bad and there will probably be (at least) a few months of improvements/testing/fixing, I made the code as close as possible to the r8169 one. Pascal Chapperon <pascal.chapperon@wanadoo.fr> deserves some special credit for testing and bug-catching. Many thanks to Lars Vahlenberg as well.
