This allows device drivers to enable MSI (Message Signaled
|
|
Interrupts). Message Signaled Interrupts enable a device to
|
|
generate an interrupt using an inbound Memory Write on its
|
|
PCI bus instead of asserting a device IRQ pin.
|
|
|
|
Use of PCI MSI interrupts can be disabled at kernel boot time
|
|
by using the 'pci=nomsi' option. This disables MSI for the
|
|
entire system.
|
|
|
|
If you don't know what to do here, say N.

Say Y here if you want the PCI core to spawn a new thread for
|
|
every PCI device that is probed. This can cause a huge
|
|
speedup in boot times on multiprocessor machines, and even a
|
|
smaller speedup on single processor machines.
|
|
|
|
But it can also cause lots of bad things to happen. A number
|
|
of PCI drivers cannot properly handle running in this way,
|
|
some will just not work properly at all, while others might
|
|
decide to blow up power supplies with a huge load all at once,
|
|
so use this option at your own risk.
|
|
|
|
It is very unwise to use this option if you are not using a
|
|
boot process that can handle devices being created in any
|
|
order. A program that can create persistant block and network
|
|
device names (like udev) is a good idea if you wish to use
|
|
this option.
|
|
|
|
Again, use this option at your own risk, you have been warned!
|
|
|
|
When in doubt, say N.

Say Y here if you want the PCI core to produce a bunch of debug
|
|
messages to the system log. Select this if you are having a
|
|
problem with PCI support and want to see more of what is going on.
|
|
|
|
When in doubt, say N.

This allows native hypertransport devices to use interrupts.
|
|
|
|
If unsure say Y.
