| |
In arch/i386/kernel/pci-pc.c, there are
/* * Sort the device list according to PCI BIOS. Nasty hack, but since some * fool forgot to define the `correct' device order in the PCI BIOS specs * and we want to be (possibly bug-to-bug ;-]) compatible with older kernels * which used BIOS ordering, we are bound to do this... */
static void __devinit pcibios_sort(void)
The problem is on my MB:
00:00.0 Host bridge: Intel Corp. e7500 [Plumas] DRAM Controller (rev 03) 00:00.1 Class ff00: Intel Corp. e7500 [Plumas] DRAM Controller Error Reporting ( rev 03) 00:03.0 PCI bridge: Intel Corp. e7500 [Plumas] HI_C Virtual PCI Bridge (F0) (rev 03) 00:03.1 Class ff00: Intel Corp. e7500 [Plumas] HI_C Virtual PCI Bridge (F1) (rev 03) 00:1d.0 USB Controller: Intel Corp. 82801CA/CAM USB (Hub (rev 02) 00:1d.1 USB Controller: Intel Corp. 82801CA/CAM USB (Hub (rev 02) 00:1e.0 PCI bridge: Intel Corp. 82801BA/CA/DB PCI Bridge (rev 42) 00:1f.0 ISA bridge: Intel Corp. 82801CA ISA Bridge (LPC) (rev 02) 00:1f.1 IDE interface: Intel Corp. 82801CA IDE U100 (rev 02) 00:1f.3 SMBus: Intel Corp. 82801CA/CAM SMBus (rev 02) 01:0c.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 02:1c.0 PIC: Intel Corp. 82870P2 P64H2 I/OxAPIC (rev 03) 02:1d.0 PCI bridge: Intel Corp. 82870P2 P64H2 Hub PCI Bridge (rev 03) 02:1e.0 PIC: Intel Corp. 82870P2 P64H2 I/OxAPIC (rev 03) 02:1f.0 PCI bridge: Intel Corp. 82870P2 P64H2 Hub PCI Bridge (rev 03) 03:07.0 Ethernet controller: Intel Corp. 82546EB Gigabit Ethernet Controller (rev 01) 03:07.1 Ethernet controller: Intel Corp. 82546EB Gigabit Ethernet Controller (rev 01) 03:08.0 RAID bus controller: 3ware Inc 3ware 7000-series ATA-RAID (rev 01)
Eth1 becomes: 03:07.0 Ethernet controller: Intel Corp. 82546EB Gigabit Ethernet Controller (rev 01)
and eth0 becomes: 03:07.1 Ethernet controller: Intel Corp. 82546EB Gigabit Ethernet Controller (rev 01)
Is that a good idea to have an option to sort the PCI device by PCI bus and slot numbers?
