[parisc-linux] gdth driver on L2000

[Eric Sproul]

Hi all,
Forgive me if this is a FAQ.  I read the website FAQ and did a little
searching, but didn't turn up anything.  I am not a kernel hacker--
that's why I'm posting here.

I am running Debian sid on a 2-way L2000-44 (rp5450).  I have
successfully built a 64-bit, SMP 2.4.25 kernel using Debian's source
(I'd be happy to share my config if anyone is interested) and the
kernel-patch-2.4.25-hppa patch.

I want to use an Intel SRCU RAID controller in this machine, so I
modified my config to build the gdth driver into the kernel.  It fails
with an error about DMA_MODE_CASCADE being undeclared.  Looking further,
I note that this is normally declared in include/asm-$ARCH/dma.h, but it
doesn't appear in include/asm-parisc/dma.h.  Is it undeclared because it
doesn't work or because no one has needed it before?  Below is the build
output.

Would I be better off with a 2.6 kernel?  I have not yet attempted to
build any 2.6 kernels on this machine.  I took the lack of stock 2.6
kernels for hppa in sid to mean that there was a problem, but I'd love
to be wrong about that.  ;)

Thanks,
Eric
