All hardware requirements listed apply to use with Linux.
The following features are now available in supported kernels: Channel Bonding documentation can be found in the Linux kernel source: /documentation/networking/The igb driver supports IEEE 1588 time stamping for kernels 2.6.30 and above.
Thus, callers are assured not only that new interrupts will not be delivered on the given line, but also that any already executing handlers have exited. All three of these functions can be called from interrupt or process context and do not sleep. You do not want, for example, to enable an interrupt line while you are handling it.
(Recall that the interrupt line of a handler is masked out while it is being serviced.) It would be rather rude to disable an interrupt line that is shared among multiple interrupt handlers.
The address bits A0 through A9 (which have traditionally been the only address bits evaluated on IBM PC XT extension cards) are hardwired to address 0x2e1.
Bits A10 through A12 are used by the µPD7210 register select lines.
Then follow the appropriate steps for building, installing, and configuring the driver.
The driver supports National Instruments PCIIA cards (sometimes also referred to as PC2A) and compatibles.is simply a signal that the hardware can send when it wants the processor's attention.Linux handles interrupts in much the same way that it handles signals in user space.A15 has been used to select an optional on- board time-of-day clock chip (MM58167A) on the original PCIIA rather than the µPD7210 (which is not implemented on later boards and clones). 0x2f7 are used for a (re-enable interrupts so the IRQ can be shared), where actually only address 0x2f0 plus the actual IRQ level is required for each card.Some clones do not appear to require this special IRQ handling, and are thus likely to not support the shared IRQ feature.
