I can't tell that v2 ever sets it. In the 8111 datasheet it looks like that bit makes it so that bits 8 & 9 of the address get ignored so that only 256B of every 1024 are accessible. I don't think that's what we want.
Looking for that I found an interesting couple of defines.
include/device/pci_def.h:#define PCI_BRIDGE_CTL_NO_ISA 0x04 /* Disable bridging of ISA ports */ include/device/pci_def.h:#define PCI_CB_BRIDGE_CTL_ISA 0x04
I can see that they're used in two different places (one for the hardware, one for the device struct), but it still seems confusing.
I think that the problem is probably in the mmio map that Ron posted yesterday.
This is my latest. The one Ron posted was from func 0 just after RAM init. This one is from func 1. After RAM init: DRAM(40)0000000000-000fffffff, ->(0), R, W, No interleave, 0 DRAM(48)0000000000-0000ffffff, ->(1), , , No interleave, 0 DRAM(50)0000000000-0000ffffff, ->(2), , , No interleave, 0 DRAM(58)0000000000-0000ffffff, ->(3), , , No interleave, 0 DRAM(60)0000000000-0000ffffff, ->(4), , , No interleave, 0 DRAM(68)0000000000-0000ffffff, ->(5), , , No interleave, 0 DRAM(70)0000000000-0000ffffff, ->(6), , , No interleave, 0 DRAM(78)0000000000-0000ffffff, ->(7), , , No interleave, 0 MMIO(80)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(88)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(90)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(98)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(a0)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(a8)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(b0)0000000000-000000ffff, ->(0,0), , , CPU disable 0, Lock 0, Non posted 0 MMIO(b8)00fc000000-00ffffffff, ->(0,0), R, W, CPU disable 0, Lock 0, Non posted 0 PCIIO(c0)00000003-01fff000 PCIIO(c0)00000000-01fff000, ->(0,0), R, W,VGA 0 ISA 0 PCIIO(c8)00000000-00000000 PCIIO(c8)00000000-00000000, ->(0,0), , ,VGA 0 ISA 0 PCIIO(d0)00000000-00000000 PCIIO(d0)00000000-00000000, ->(0,0), , ,VGA 0 ISA 0 PCIIO(d8)00000000-00000000 PCIIO(d8)00000000-00000000, ->(0,0), , ,VGA 0 ISA 0 CONFIG(e0)0000003f-00000000 ->(0,0),R W CE 0 CONFIG(e4)00000000-00000000 ->(0,0), CE 0 CONFIG(e8)00000000-00000000 ->(0,0), CE 0 CONFIG(ec)00000000-00000000 ->(0,0), CE 0
