This is the preferred method due to speed but it 168 limits the system to just 64MB of PCI memory. This can be 169 problematic if using video cards and other memory-heavy devices. 170 171 2) If > 64MB of memory space is required, the IXP4xx can be 172 configured to use indirect registers to access PCI This allows 173 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. 174 The disadvantage of this is that every PCI access requires 175 three local register accesses plus a spinlock, but in some 176 cases the performance hit is acceptable. In addition, you cannot 177 mmap() PCI devices in this case due to the indirect nature 178 of the PCI window. 179 180 By default, the direct method is used. Choose this option if you 181 need to use the indirect method instead. If you don't know 182 what you need, leave this option unselected. 183 184endmenu 185 186endif 187
