There is - * a page register that controls bank and packet buffer access. We guard - * this with ei_local->page_lock. Nobody should assume or set the page other - * than zero when the lock is not held. Lock holders must restore page 0 - * before unlocking. Even pure readers must take the lock to protect in - * page 0. - * - * To make life difficult the chip can also be very slow. We therefore can't - * just use spinlocks. For the longer lockups we disable the irq the device - * sits on and hold the lock. We must hold the lock because there is a dual - * processor case other than interrupts (get stats/set multicast list in - * parallel with each other and transmit). - * - * Note: in theory we can just disable the irq on the card _but_ there is - * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs" - * enter lock, take the queued irq. So we waddle instead of flying. - * - * Finally by special arrangement for the purpose of being generally - * annoying the transmit function is called bh atomic. That places - * restrictions on the user context callers as disable_irq won't save - * them. - * - * Additional explanation of problems with locking by Alan Cox: - * - * "The author (me) didn't use spin_lock_irqsave because the slowness of the - * card means that approach caused horrible problems like losing serial data - * at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA - * chips with FPGA front ends. - * - * Ok the logic behind the 8390 is very simple: - * - * Things to know - * - IRQ delivery is asynchronous to the PCI bus - * - Blocking the local CPU IRQ via spin locks was too slow - * - The chip has register windows needing locking work - * - * So the path was once (I say once as people appear to have changed it - * in the mean time and it now looks rather bogus if the changes to use - * disable_irq_nosync_irqsave are disabling the local IRQ) - * - * - * Take the page lock - * Mask the IRQ on chip - * Disable the IRQ (but not mask locally- someone seems to have - * broken this with the lock validator stuff) - * [This must be _nosync as the page lock may otherwise - * deadlock us] - * Drop the page lock and turn IRQs back on - * - * At this point an existing IRQ may still be running but we can't - * get a new one - * - * Take the lock (so we know the IRQ has terminated) but don't mask - * the IRQs on the processor - * Set irqlock [for debug] - * - * Transmit (slow as ****) - * - * re-enable the IRQ - * - * - * We have to use disable_irq because otherwise you will get delayed - * interrupts on the APIC bus deadlocking the transmit path. - * - * Quite hairy but the chip simply wasn't designed for SMP and you can't - * even ACK an interrupt without risking corrupting other parallel - * activities on the chip."

Nobody should assume or set the page other - * than zero when the lock is not held. Lock holders must restore page 0 - * before unlocking. Even pure readers must take the lock to protect in - * page 0. - * - * To make life difficult the chip can also be very slow. We therefore can't - * just use spinlocks. For the longer lockups we disable the irq the device - * sits on and hold the lock. We must hold the lock because there is a dual - * processor case other than interrupts (get stats/set multicast list in - * parallel with each other and transmit). - * - * Note: in theory we can just disable the irq on the card _but_ there is - * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs" - * enter lock, take the queued irq. So we waddle instead of flying. - * - * Finally by special arrangement for the purpose of being generally - * annoying the transmit function is called bh atomic. That places - * restrictions on the user context callers as disable_irq won't save - * them. - * - * Additional explanation of problems with locking by Alan Cox: - * - * "The author (me) didn't use spin_lock_irqsave because the slowness of the - * card means that approach caused horrible problems like losing serial data - * at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA - * chips with FPGA front ends. - * - * Ok the logic behind the 8390 is very simple: - * - * Things to know - * - IRQ delivery is asynchronous to the PCI bus - * - Blocking the local CPU IRQ via spin locks was too slow - * - The chip has register windows needing locking work - * - * So the path was once (I say once as people appear to have changed it - * in the mean time and it now looks rather bogus if the changes to use - * disable_irq_nosync_irqsave are disabling the local IRQ) - * - * - * Take the page lock - * Mask the IRQ on chip - * Disable the IRQ (but not mask locally- someone seems to have - * broken this with the lock validator stuff) - * [This must be _nosync as the page lock may otherwise - * deadlock us] - * Drop the page lock and turn IRQs back on - * - * At this point an existing IRQ may still be running but we can't - * get a new one - * - * Take the lock (so we know the IRQ has terminated) but don't mask - * the IRQs on the processor - * Set irqlock [for debug] - * - * Transmit (slow as ****) - * - * re-enable the IRQ - * - * - * We have to use disable_irq because otherwise you will get delayed - * interrupts on the APIC bus deadlocking the transmit path. - * - * Quite hairy but the chip simply wasn't designed for SMP and you can't - * even ACK an interrupt without risking corrupting other parallel - * activities on the chip."
