help compiling drivers for HPT RocketRaid 2720 on 3.8

Hi, I'm trying to build a driver for the Highpoint RR 2720 on the new Linux kernel 3.8

I've downloaded the drivers from the highpoint site: http://highpoint-tech.com/USA_new/pr...pport_sas6.htm (I used the Linux Open Source 1.4 driver.) I had the card working on 3.5.0-21 but now when I run make the makefile yells at me saying it only works on 2.4, 2.6 and 3.0 ...

Anybody have any expertise or can I provide some more info?

Thanks!

The problematic code is in rr272x_1x-linux-src-v1.4/inc/linux_64mpa/Makefile.def. It's supposed to detect the major and minor kernel versions, but it depends on a kernel header file called "version.h" which no longer exists.

It's possible to work around that problem but there are a few other incompatibilities as well. Unless someone knowledgeable updates the source code, the driver just won't compile.

Thanks for the reply. If I modified makefile.def to not check for the header version, would it build (albeit not necessarily correctly)? I did get it to build for 3.5, but I don't remember exactly what mods I made to get it to work...

You can fudge the version detection by manually defining KERNEL_VER_MAJOR and KERNEL_VER_MINOR in Makefile.def.

I tried compiling under 3.7.3 and got this:

fudge... Can I take the compiled driver from 3.5.0-21 and use it in 3.8 without recompiling? I see it in /lib/modules/3.5.0-21-generic/kernel/driver/scsi/ but I think I need to apply it to initrd, which I'm unsure of...

You could try, but it's not very likely to work. If you can successfully insmod the old module in a more recent kernel, it could be worth a shot.
