Hmm even with DMA built in my disk (Seagate 5400.8) still "configured" for
PIO4.
This is probably my fault. Tim, could you respin the patch anyway since
it doesn't apply cleanly to the 2.6.27 kernel? :)
This did work for me once but we were still using a SUSE kernel (from
11.0) to patch it onto and another interrupt controller patch crippled
performance so it wasn't a really good test..

Betreff: Re: [PATCH]: [MPC5200] Add ATA DMA support
Oddly I built 2.6.27.2 with the patch and the Efika "waited" for a disk to
appear and didn't get anywhere. If I set libata.dma=0 then it complained about missing
symbols (but not with it enabled!).
This was a clean SUSE kernel from Factory, with only the ATA patch applied with
a few hand-merges (pata_mpc52xx.c has had a line of whitespace removed at some
point, but otherwise identical).

Tim, Grant,
I have tested the patch on our MPC5200B based board with Kingston Elite Pro
CF-card and it worked fine with DMA2. I have port the patch back to 2.6.24.7
Kernel and I can't detect problems our errors, even with big files (40 mB) over
FEC wich I save to card . We get performance up to 10,5mB/s which is near to
the max. speed.

Sounds good to me. You will get more testers that way. I can pick
it up for -next if everything else looks good.
Here are the new patches; tested against 2.6.27-rc3.
Thanks,
Tim
