PCI Device Driver: Porting to 2.6 kernel

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I am porting PCI fabric device drivers from the 2.4 kernel to 2.6. Although the driver finds the devices and calls exported pci core functions to attach and enable them, entries are not being made in the /proc/bus/pci/devices file.

The devices are accessed through a fabric bridge attached to a fabric switchcard on another chassis. The driver allocated bridge numbers arbitrarily starting at 80. Entries for accessing the device do get created in /proc/bus/pci:
ls /proc/bus/pci
00  01  02  03  04  05  06  07  08  81  82  83  devices
/proc/bus/pci/81: 00.0  01.0  02.0  03.0
/proc/bus/pci/82: 00.0
/proc/bus/pci/83: 00.0  01.0

However, corresponding entries are not being created in /sys/bus/pci/devices.

I might add, these drivers are production code that works on the 2.4 kernel. Minor modifications had to be made for 2.6, e.g. some functions have been renamed and the read/write routines take a size parameter instead of having separate functions for 8, 16 and 32 bit operations.

I have not been able to locate the core code that makes the entries in the /proc/bus/pci/devices file or creates the device entries in /sys/bus/pci/devices.

Has anyone encountered these problems?

John
