(gdb) l *(__pci_bus_find_cap_start + 0x1e) 0xffffffff81239245 is in __pci_bus_find_cap_start (/home/lab/git/xhci-sarah/drivers/pci/pci.c:196). 191 { 192 u16 status; 193 194 pci_bus_read_config_word(bus, devfn, PCI_STATUS, &status); 195 if (!(status & PCI_STATUS_CAP_LIST)) 196 return 0; 197 198 switch (hdr_type) { 199 case PCI_HEADER_TYPE_NORMAL: 200 case PCI_HEADER_TYPE_BRIDGE: (gdb) l *(pci_bus_read_config_dword + 0x57) 0xffffffff81237002 is in pci_bus_read_config_dword (/home/lab/git/xhci-sarah/drivers/pci/access.c:58). 53 return res; \ 54 } 55 56 PCI_OP_READ(byte, u8, 1) 57 PCI_OP_READ(word, u16, 2) 58 PCI_OP_READ(dword, u32, 4) 59 PCI_OP_WRITE(byte, u8, 1) 60 PCI_OP_WRITE(word, u16, 2) 61 PCI_OP_WRITE(dword, u32, 4) 62 (gdb) A bad value for 'bus' or 'devfn' I guess? Unfortunately I won't be able to spend any more time on this today, and next week I am on vacation. You should think about getting your own xhci card for your PC. You can find them on the internet. In fact, I think TI makes one :) -- Paul -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
