This is the preferred method due to speed but it 109 limits the system to just 64MB of PCI memory. This can be 110 problamatic if using video cards and other memory-heavy devices. 111 112 2) If > 64MB of memory space is required, the IXP4xx can be 113 configured to use indirect registers to access PCI This allows 114 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. 115 The disadvantadge of this is that every PCI access requires 116 three local register accesses plus a spinlock, but in some 117 cases the performance hit is acceptable. In addition, you cannot 118 mmap() PCI devices in this case due to the indirect nature 119 of the PCI window. 120 121 By default, the direct method is used. Choose this option if you 122 need to use the indirect method instead. If you don't know 123 what you need, leave this option unselected. 124 125endmenu 126 127endif 128
