136 | help |
137 | IXP4xx provides two methods of accessing PCI memory space: | |
138 | ||
139 | 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB). | |
140 | To access PCI via this space, we simply ioremap() the BAR | |
141 | into the kernel and we can use the standard read[bwl]/write[bwl] | |
142 | macros. This is the preferred method due to speed but it | |
143 | limits the system to just 64MB of PCI memory. This can be | |
3cb2fccc | 144 | problematic if using video cards and other memory-heavy devices. |
1da177e4 LT |
145 | |
146 | 2) If > 64MB of memory space is required, the IXP4xx can be | |
147 | configured to use indirect registers to access PCI This allows | |
148 | for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. | |
c41045a4 | 149 | The disadvantage of this is that every PCI access requires |
1da177e4 LT |
150 | three local register accesses plus a spinlock, but in some |
151 | cases the performance hit is acceptable. In addition, you cannot | |
152 | mmap() PCI devices in this case due to the indirect nature | |
153 | of the PCI window. | |
154 | ||
155 | By default, the direct method is used. Choose this option if you | |
156 | need to use the indirect method instead. If you don't know | |
157 | what you need, leave this option unselected. | |
