config PCI

bool "PCI support"
|

help
|

|
|
Find out whether you have a PCI motherboard. PCI is the name of a
|
||
|
|
bus system, i.e. the way the CPU talks to the other stuff inside
|
||
|
|
your box. If you have PCI, say Y, otherwise N.
|
||
|
|
|
||
|
|
The PCI-HOWTO, available from
|
||
|
|
<http://www.tldp.org/docs.html#howto>, contains valuable
|
||
|
|
information about which PCI hardware does work under Linux and which
|
||
|
|
doesn't.

Enable this option if your platform does not have a CPU cache which
|
||
|
|
remains coherent with PCI DMA. It is safest to say 'Y', although you
|
||
|
|
will see better performance if you can say 'N', because the PCI DMA
|
||
|
|
code will not have to flush the CPU's caches. If you have a PCI host
|
||
|
|
bridge integrated with your SH CPU, refer carefully to the chip specs
|
||
|
|
to see if you can say 'N' here. Otherwise, leave it as 'Y'.

help
|

|
|
Selecting this option will cause the PCI auto code to leave your
|
||
|
|
BAR values alone. Otherwise they will be updated automatically. If
|
||
|
|
for some reason, you have a board that simply refuses to work
|
||
|
|
with its resources updated beyond what they are when the device
|
||
|
|
is powered up, set this to N. Everyone else will want this as Y.
