118 | config IXP4XX_INDIRECT_PCI | |
119 | bool "Use indirect PCI memory access" | |
120 | help | |
121 | IXP4xx provides two methods of accessing PCI memory space: | |
122 | ||
123 | 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB). | |
124 | To access PCI via this space, we simply ioremap() the BAR | |
125 | into the kernel and we can use the standard read[bwl]/write[bwl] | |
126 | macros. This is the preferred method due to speed but it | |
127 | limits the system to just 64MB of PCI memory. This can be | |
128 | problamatic if using video cards and other memory-heavy devices. | |
129 | ||
130 | 2) If > 64MB of memory space is required, the IXP4xx can be | |
131 | configured to use indirect registers to access PCI This allows | |
132 | for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus. | |
133 | The disadvantadge of this is that every PCI access requires | |
134 | three local register accesses plus a spinlock, but in some | |
135 | cases the performance hit is acceptable. In addition, you cannot | |
136 | mmap() PCI devices in this case due to the indirect nature | |
137 | of the PCI window. | |
138 | ||
139 | By default, the direct method is used. Choose this option if you | |
140 | need to use the indirect method instead. If you don't know | |
141 | what you need, leave this option unselected. | |
