Hello I moved a Kodicom card (http://linuxtv.org/wiki/index.php/Kodicom_4400R) from an older machine to a new with a PCIe bridge. Bttv modprobe can no longer find the BT878 chips behind the PCI bridge, though the bridge is found. The bridge is a PCI6140 AKA "Hint HB6". I noticed a PCI quirk for it, tried manually adding the IO/memory spaces that were originally logged, but doesn't help. This machine runs kernel 3.12.52 (x64), but it also fails on 3.0.76. The BT878 chips were recognised on the older machine also running 3.0.76 but with a vanilla PCI bus. Relevant dmesg lines when not working (can post entire logs if helpful) [ 0.089046] pci 0000:00:1c.2: scanning [bus 03-05] behind bridge, pass 0 [ 0.089105] pci_bus 0000:03: scanning bus [ 0.089136] pci 0000:03:00.0: [1283:8893] type 01 class 0x060401 [ 0.089335] pci 0000:03:00.0: supports D1 D2 [ 0.089336] pci 0000:03:00.0: PME# supported from D0 D1 D2 D3hot D3cold [ 0.089343] pci 0000:03:00.0: PME# disabled [ 0.089382] pci_bus 0000:03: fixups for bus [ 0.089383] pci 0000:00:1c.2: PCI bridge to [bus 03-05] [ 0.089397] pci 0000:03:00.0: scanning [bus 04-05] behind bridge, pass 0 [ 0.089487] pci_bus 0000:04: scanning bus [ 0.089523] pci 0000:04:01.0: [3388:0021] type 01 class 0x060400 [ 0.089729] pci 0000:04:01.0: supports D1 D2 [ 0.089730] pci 0000:04:01.0: PME# supported from D1 D2 D3hot D3cold [ 0.089738] pci 0000:04:01.0: PME# disabled [ 0.089871] pci_bus 0000:04: fixups for bus [ 0.089872] pci 0000:03:00.0: PCI bridge to [bus 04-05] (subtractive decode) [ 0.089906] pci 0000:03:00.0: bridge window [??? 0x00000000 flags 0x0] (subtractive decode) [ 0.089907] pci 0000:03:00.0: bridge window [??? 0x00000000 flags 0x0] (subtractive decode) [ 0.089908] pci 0000:03:00.0: bridge window [??? 0x00000000 flags 0x0] (subtractive decode) [ 0.089910] pci 0000:03:00.0: bridge window [??? 0x00000000 flags 0x0] (subtractive decode) [ 0.089914] pci 0000:04:01.0: scanning [bus 05-05] behind bridge, pass 0 [ 0.090011] pci_bus 0000:05: scanning bus [ 0.090116] pci_bus 0000:05: fixups for bus [ 0.090117] pci 0000:04:01.0: PCI bridge to [bus 05] [ 0.090139] pci_bus 0000:05: bus scan returning with max=05 [ 0.090148] pci 0000:04:01.0: scanning [bus 05-05] behind bridge, pass 1 [ 0.090159] pci_bus 0000:04: bus scan returning with max=05 [ 0.090167] pci 0000:03:00.0: scanning [bus 04-05] behind bridge, pass 1 [ 0.090177] pci_bus 0000:03: bus scan returning with max=05 [ 0.090181] pci 0000:00:1c.0: scanning [bus 01-01] behind bridge, pass 1 [ 0.090187] pci 0000:00:1c.1: scanning [bus 02-02] behind bridge, pass 1 [ 0.090193] pci 0000:00:1c.2: scanning [bus 03-05] behind bridge, pass 1 [ 0.090197] pci_bus 0000:00: bus scan returning with max=05 Working -
