213 config IXP4XX_INDIRECT_PCI
214 bool "Use indirect PCI memory access"
217 IXP4xx provides two methods of accessing PCI memory space:
219 1) A direct mapped window from 0x48000000 to 0x4BFFFFFF (64MB).
220 To access PCI via this space, we simply ioremap() the BAR
221 into the kernel and we can use the standard read[bwl]/write[bwl]
222 macros. This is the preferred method due to speed but it
223 limits the system to just 64MB of PCI memory. This can be
224 problematic if using video cards and other memory-heavy devices.
226 2) If > 64MB of memory space is required, the IXP4xx can be
227 configured to use indirect registers to access the whole PCI
228 memory space. This currently allows for up to 1 GB (0x10000000
229 to 0x4FFFFFFF) of memory on the bus. The disadvantage of this
230 is that every PCI access requires three local register accesses
231 plus a spinlock, but in some cases the performance hit is
232 acceptable. In addition, you cannot mmap() PCI devices in this
233 case due to the indirect nature of the PCI window.
235 By default, the direct method is used. Choose this option if you
236 need to use the indirect method instead. If you don't know
237 what you need, leave this option unselected.
