Marius,
I would like to say that thanks for fixing the ata-marvell driver for the
SuperMicro Sata card on sparc64, atleast the blade 1000. Your patch has
enabled the card to detect the disk drive and complete booting. Not only
that, I was able to go all the way and create a new partition on the disk,
newfs it, and mount it. I was able to copy 1.6gigs of data onto the
partition, and was able to copy data from the partition to another
directory within the same partition at a tune of about 40MB/s.
Before that patch, the system was not able to complete booting.
Out of curiosity, ofcourse, what does the patch do? Does it basically
disable 64-bit and dma for the driver on sparc64? This is a PCI-X 133mhz
card. It would be a dream to get half the band-width as it is in a 66mhz
pci slot.
Thanks, Robert.
