/* The EtherExpress 16 is a fairly simple card, based on a shared-memory
* design using the i82586 Ethernet coprocessor. It bears no relationship,
* as far as I know, to the similarly-named "EtherExpress Pro" range.
*
* Historically, Linux support for these cards has been very bad. However,
* things seem to be getting better slowly.
*/
/* If your card is confused about what sort of interface it has (eg it
* persistently reports "10baseT" when none is fitted), running 'SOFTSET /BART'
* or 'SOFTSET /LISA' from DOS seems to help.
*/
/* Here's the scoop on memory mapping.
*
* There are three ways to access EtherExpress card memory: either using the
* shared-memory mapping, or using PIO through the dataport, or using PIO
* through the "shadow memory" ports.
*
* The shadow memory system works by having the card map some of its memory
* as follows:
*
* (the low five bits of the SMPTR are ignored)
*
* base+0x4000..400f memory at SMPTR+0..15
* base+0x8000..800f memory at SMPTR+16..31
* base+0xc000..c007 dubious stuff (memory at SMPTR+16..23 apparently)
* base+0xc008..c00f memory at 0x0008..0x000f
*
* This last set (the one at c008) is particularly handy because the SCB
* lives at 0x0008. So that set of ports gives us easy random access to data
* in the SCB without having to mess around setting up pointers and the like.
* We always use this method to access the SCB (via the scb_xx() functions).
*
* Dataport access works by aiming the appropriate (read or write) pointer
* at the first address you're interested in, and then reading or writing from
* the dataport. The pointers auto-increment after each transfer. We use
* this for data transfer.
*
* We don't use the shared-memory system because it allegedly doesn't work on
* all cards, and because it's a bit more prone to go wrong (it's one more
* thing to configure...).
*/
/* Known bugs:
*
* - The card seems to want to give us two interrupts every time something
* happens, where just one would be better.
*/
/*
*
* Note by Zoltan Szilagyi 10-12-96:
*
* I've succeeded in eliminating the "CU wedged" messages, and hence the
* lockups, which were only occurring with cards running in 8-bit mode ("force
* 8-bit operation" in Intel's SoftSet utility). This version of the driver
* sets the 82586 and the ASIC to 8-bit mode at startup; it also stops the
* CU before submitting a packet for transmission, and then restarts it as soon
* as the process of handing the packet is complete. This is definitely an
* unnecessary slowdown if the card is running in 16-bit mode; therefore one

* Update by David Woodhouse 11/5/99:
*
* I've seen "CU wedged" messages in 16-bit mode, on the Alpha architecture.

[netdrvr] eexpress: IPv6 fails - multicast problems Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577 I was unable to access a computer containing an Intel EtherExpress 16 network card using IPv6. I traced this to failure of neighbour discovery. When I used an "ip -6 neigh add" command, on the computer attempting access, to insert a binding between the IPv6 address of the computer with the Intel EtherExpress 16 network card and the card's ethernet address, I was able to access that computer using IPv6. Neighbour discovery requires working multicast. The driver sources file eexpress.c contains an approximately 30 line function eexp_setup_filter used when loading multicast addresses. I found 3 problems in this function 1) It wrote the number of multicast addresses to the card instead of the number of bytes in the multicast addresses. 2) When loading multiple multicast addresses it loaded the first one provided multiple times instead of loading each one once. 3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the test for the error situation of 'dmi' being NULL. Correcting these problems allows the computer with the Intel EtherExpress 16 network card to found by IPv6 neighbour discovery. p.s. There is some information on the Intel EtherExpress 16 at http://www.intel.com/support/etherexpress/vintage/sb/cs-013500.htm Datasheet for the Intel 82586 ethernet controller used by the card http://www.datasheetcatalog.com/datasheets_pdf/8/2/5/8/82586.shtml Signed-off-by: Bruce Robson <bns_robson@hotmail.com> Cc: Jeff Garzik <jeff@garzik.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers 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.

[NET]: Avoid allocating skb in skb_pad 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.

[netdrvr] eexpress: IPv6 fails - multicast problems Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577 I was unable to access a computer containing an Intel EtherExpress 16 network card using IPv6. I traced this to failure of neighbour discovery. When I used an "ip -6 neigh add" command, on the computer attempting access, to insert a binding between the IPv6 address of the computer with the Intel EtherExpress 16 network card and the card's ethernet address, I was able to access that computer using IPv6. Neighbour discovery requires working multicast. The driver sources file eexpress.c contains an approximately 30 line function eexp_setup_filter used when loading multicast addresses. I found 3 problems in this function 1) It wrote the number of multicast addresses to the card instead of the number of bytes in the multicast addresses. 2) When loading multiple multicast addresses it loaded the first one provided multiple times instead of loading each one once. 3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the test for the error situation of 'dmi' being NULL. Correcting these problems allows the computer with the Intel EtherExpress 16 network card to found by IPv6 neighbour discovery. p.s.

[netdrvr] eexpress: IPv6 fails - multicast problems Taken from http://bugzilla.kernel.org/show_bug.cgi?id=10577 I was unable to access a computer containing an Intel EtherExpress 16 network card using IPv6. I traced this to failure of neighbour discovery. When I used an "ip -6 neigh add" command, on the computer attempting access, to insert a binding between the IPv6 address of the computer with the Intel EtherExpress 16 network card and the card's ethernet address, I was able to access that computer using IPv6. Neighbour discovery requires working multicast. The driver sources file eexpress.c contains an approximately 30 line function eexp_setup_filter used when loading multicast addresses. I found 3 problems in this function 1) It wrote the number of multicast addresses to the card instead of the number of bytes in the multicast addresses. 2) When loading multiple multicast addresses it loaded the first one provided multiple times instead of loading each one once. 3) The setting of pointer 'data' from 'dmi->dmi_addr' occured before the test for the error situation of 'dmi' being NULL. Correcting these problems allows the computer with the Intel EtherExpress 16 network card to found by IPv6 neighbour discovery. p.s. There is some information on the Intel EtherExpress 16 at http://www.intel.com/support/etherexpress/vintage/sb/cs-013500.htm Datasheet for the Intel 82586 ethernet controller used by the card http://www.datasheetcatalog.com/datasheets_pdf/8/2/5/8/82586.shtml Signed-off-by: Bruce Robson <bns_robson@hotmail.com> Cc: Jeff Garzik <jeff@garzik.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
