ATA DMA status?

[Nick Withers]

Hi guys,

Sorry to hassle, but how's the ATA DMA stuff (original CFT:
http://lists.freebsd.org/pipermail/freebsd-ppc/2008-September/003054.html and http://lists.freebsd.org/pipermail/freebsd-ppc/2008-October/003187.html, http://lists.freebsd.org/pipermail/freebsd-ppc/2008-October/003314.html, for instance) going?

According to
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/powerpc/powermac/ata_dbdma.c (I'm still clinging on to CVS :-)) the MFC's been behind for a while - does this indicate there're still big problems? I've only got the one G4 box on 7-STABLE and am somewhat reluctant to test anything too "alpha" on it...

If I were to test it out on 7-STABLE, though, do I still just need the
http://people.freebsd.org/~nwhitehorn/apple-ata-dma.patch patch (it
seems outdated, e.g., not including the changes from the latest rev
(184429 / CVS 1.2) to ata_dbdma.c)? Is
http://people.freebsd.org/~nwhitehorn/kauai.marcel.patch applicable?

Thanks very much all, I'm looking forward to having DMA!
