2006-10-30Revert "r8169: mac address change support"Linus Torvalds1-38/+0
This reverts commit a2b98a697fa4e7564f78905b83db122824916cf9. As per Guennadi Liakhovetski, the mac address change support code breaks some normal uses (_without_ any address changes), and until it's all sorted out, we're better off without it. Says Francois: "Go revert it. Despite what I claimed, I can not find a third-party confirmation by email that it works elsewhere. It would probably be enough to remove the call to __rtl8169_set_mac_addr() in rtl8169_hw_start() though."

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-4/+3
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.

2006-09-11r8169: quirk for the 8110sb on arm platformFrancois Romieu1-2/+7
Inverting the write ordering of the TxDescAddr{High/Low} registers suffices to trigger a sabbat of PCI errors which make the device completely dysfunctional. The issue has not been reported on a different platform. Switching from MMIO accesses to I/O ones as done in Realtek's own driver fixes (papers over ?) the bug as well but I am not thrilled to see everyone pay the I/O price for an obscure bug.

2006-07-27r8169: sync with vendor's driverFrancois Romieu1-74/+144
- add several PCI ID for the PCI-E adapters ; - new identification strings ; - the RTL_GIGA_MAC_VER_ defines have been renamed to closely match the out-of-tree driver. It makes the comparison less hairy ; - various magic ; - the PCI region for the device with PCI ID 0x8136 is guessed. Explanation: the in-kernel Linux driver is written to allow MM register accesses and avoid the IO tax. The relevant BAR register was found at base address 1 for the plain-old PCI 8169. User reported lspci show that it is found at base address 2 for the new Gigabit PCI-E 816{8/9}.

2006-06-23[NET]: Merge TSO/UFO fields in sk_buffHerbert Xu1-1/+1
Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not going to scale if we add any more segmentation methods (e.g., DCCP). So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-06-23[NET]: Avoid allocating skb in skb_padHerbert Xu1-2/+1
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.

Depending on the clock management, it triggers lost ticks events.
