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. + +endmenu + +endif |
