| 364 | Actually, another niggle I find while trying to adopt this patch today. In pci_pci.c, when allocating the bridge window, we try to allocate start=0x0, end=0xfffff. That's always going to fail if the pci memory range is [0xf8000000,0xfbffffff] (as in the case of the rpi controller). Somehow we need to adjust that bridge window region into a pci address range. Also, it seems that we don't actually check if sc->ranges[i] is large enough to hold the requested [start, end] resource. | |
