2007-04-11skge: fix wake on lanStephen Hemminger
Need to rework wake on lan code to setup properly and get activated on shutdown (and suspend), not when ethtool is run. This does not need to go to stable queue because wake on lan was not even included in 2.6.20 (or earlier versions).

2007-04-11skge: turn carrier off when downStephen Hemminger
Driver needs to turn off carrier when down, otherwise it can confuse bonding and bridging and looks like carrier is on immediately when it is brought back up. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-03-23skge: use per-port phy lockingStephen Hemminger
Rather than a workqueue and a per-board mutex to control PHY, use a tasklet and spinlock. Tasklet is lower overhead and works just as well for this. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-03-23skge: mask irqs when device downStephen Hemminger

2007-03-23skge: deadlock on tx timeoutStephen Hemminger

2007-03-15skge: set mac address bonding fixStephen Hemminger
When bonding does fail over it calls set_mac_address. When this happens as the result of another port going down, the phy_mutex that is common to both ports is held, so it deadlocks. Setting the address doesn't need to do anything that needs the phy_mutex, it already has the RTNL to protect against other admin actions. This change just disables the receiver to avoid any hardware confusion while address is changing.

2007-02-27skge: fix transmitter flow controlStephen Hemminger
It looks like the skge driver inherited another bug from the sk98lin code. If I send from 1000mbit port to a machine on 100mbit port, the switch should be doing hardware flow control, but no pause frames show up in the statistics. This is the analog of the recent sky2 fixes. The device needs to listen for multicast pause frames and then not discard them.

2007-02-20skge: race with workq and RTNLStephen Hemminger
If a workqueue function that needs RTNL is running when skge_down is called then a deadlock is possible. Fix by only clearing the timer, and handling the flush_scheduled_work on removal. This work queue is only ever used for the old fiber based boards. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>

2007-02-06skge: handle zero address at openStephen Hemminger
Some motherboards are broken and have no address set. Failing at probe time prevents the device from ever being used (like to download a fixed BIOS).

2006-12-26netpoll: drivers must not enable IRQ unconditionally in their NAPI handlerFrancois Romieu
net/core/netpoll.c::netpoll_send_skb() calls the poll handler when it is available. As netconsole can be used from almost any context, IRQ must not be enabled blindly in the NAPI handler of a driver which supports netpoll. b57bd06655a028aba7b92e1c19c2093e7fcfb341 fixed the issue for the 8139too.c driver.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.
