Porting PCi driver from 2.6.32 to 3.x kernel version

[Omkar Houddin]

Hi,

Im trying to port a PCI Driver from 2.6.32 to 3.11.6-4-desktop kernel
verion.

I tried to update the driver source to compile correctly and load fine.

But when I'm trying to send command some thing like a soft reset which re
intializes the configuration table. and at that point of time the I'm
getting different value than what I used to get on 2.6.32 kernel version.

*3.11.6.4 Kernel verison:*

scull_ioctl: SCULL_SOFT_RESET
2014-08-04T08:06:24.839008-07:00  kernel: [ 2065.546754] calling

where as before i.e is in 2.6.32

 scull_ioctl: SCULL_SOFT_RESET

*Aug  4 16:39:23  kernel: [53429.533213]  Write SCULL Config Table*

the function I used for register read is:

*unsigned int msgu_reg_read(unsigned int msgu_reg_offset)*
*{*
*    unsigned int addr;*
*    unsigned int data;*

*    addr = i2o_addr + msgu_reg_offset;*
*    data = readl((void *)addr);*

*    return data;*

*}*


Could anyone please help me how to solve this issue?

Thank you,

OH.
