I saw the more recent postings...
My understanding is that the TX4650 has the RAID-5 XOR ASICs to
accelerate the reed-solomon code calculations... hence my wanting to use
this driver.
I picked up the patches that you pointed me at (including "The Czar's",
which was necessary to compile on 2.6.25 and subsequent)...
Then I looked at:
http://fedoraproject.org/wiki/Docs/CustomKernel?highlight=#Building_Only_Kernel_Modules
but had some questions about that.
The example is a little thin. It doesn't explain what to do if you need
to pass in extra C flags, extra include directories, or if your driver
has several subdirectories that need to be compiled and linked together
(or if it is a partial-source release, and has canned object files that
also need to be linked in).
Anyone have a real-life example that they can point me at that does this?
Thanks,
-Philip
