- config IXP4XX_INDIRECT_PCI
- bool "Use indirect PCI memory access"
- 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
- problamatic 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 PCI This allows
- for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
- The disadvantadge 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.
