- help
- IXP4xx provides two methods of accessing PCI memory space:
-
- 1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
- To access PCI via this space, we simply ioremap() the BAR
- into the kernel and we can use the standard read[bwl]/write[bwl]
- macros. This is the preferred method due to speed but it
- limits the system to just 64MB of PCI memory. This can be
- problematic if using video cards and other memory-heavy devices.
-
- 2) If > 64MB of memory space is required, the IXP4xx can be
- configured to use indirect registers to access the whole PCI
- memory space. This currently allows for up to 1 GB (0x10000000
- to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
- is that every PCI access requires three local register accesses
- plus a spinlock, but in some cases the performance hit is
- acceptable. In addition, you cannot mmap() PCI devices in this
- case due to the indirect nature of the PCI window.
-
- By default, the direct method is used. Choose this option if you
- need to use the indirect method instead. If you don't know
- what you need, leave this option unselected.
