maybe this third window stuff in cia_enable_broken_tbia() is why i can't seem to get the third window to open up. from my reading of the 21174 docs, my code should work. since T2_BASE is at 0x40000000 for 1gig, i'd think T3_BASE should be at 0x80000000. am i missing something?
hose->sg_pci = iommu_arena_new(hose, 0xc0000000, 0x08000000, 32768); *(vip)CIA_IOC_PCI_W3_BASE = 0xc0000000 | 1; *(vip)CIA_IOC_PCI_W3_MASK = (0x08000000 - 1) & 0xfff00000; *(vip)CIA_IOC_PCI_T3_BASE = 0x80000000 >> 2;
