Porting from Solaris to Linux

[Ganesan]

Hi,
I am new to this forum and newbie to device drivers. I need to port a device driver code from Solaris to Linux. The Solaris code uses DDI (device driver Interface) system calls (for eg ddi_soft_state_init, ddi_get_instance) which are specific to Solaris. I would like to know whether there are any corresponding system calls in Linux so that I can replace the DDI system calls directly or should I need to re-write the driver code newly again.

Thanks in advance,
Ganesan.

are you using a SPARC based SUN system?

[Ganesan]

Yes, currently the code is available for Solaris (SPARC). I need to port it to Linux.

Well, I for once haven't ever used Sun's DDI, so I don't really know what either ddi_soft_state_init or ddi_get_instance actually do. Because of that, it's a bit hard to find a Linux kernel counterpart. =)
