This is the preferred method due to speed but it 163 limits the system to just 64MB of PCI memory. This can be 164 problematic if using video cards and other memory-heavy devices. 165 166 2) If > 64MB of memory space is required, the IXP4xx can be 167 configured to use indirect registers to access PCI This allows 168 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. 169 The disadvantage of this is that every PCI access requires 170 three local register accesses plus a spinlock, but in some 171 cases the performance hit is acceptable. In addition, you cannot 172 mmap() PCI devices in this case due to the indirect nature 173 of the PCI window. 174 175 By default, the direct method is used. Choose this option if you 176 need to use the indirect method instead. If you don't know 177 what you need, leave this option unselected. 178 179endmenu 180 181endif 182
