Hello, I've got the WD7000 driver to work. I haven't got scatter/gather to work on my controller (it may not support it...), so I haven't got any chance to test it. The current version doesn't support s/g. What I do instead is allocate a (physically contiguous) buffer in the driver, which the driver use for all DMA. This will give some performance reduction, but it's the only way I know to get it to work on my controller. I've tested the driver on my 2.0R system, it works with my Tandberg TDC3640. I've also made some testing with a QUANTUM P105SS. The source, with my config file, is uploaded at the incoming directory of ftp.cdrom.com. -Olof -------------------+-----------------------+------------------------------------ Olof Johansson | Address: | Phone: +46-10-695-8364 -------------------+ VPL 914 Johansson +------------------------------------ offe@ludd.luth.se | 2 komp, 3 plut | Who is General Failure, and why d92-ojn@sm.luth.se | Box 9106 | is he reading my disk? offe@sdf.luth.se | 961 19 Boden / SWEDEN | (MSDOS - just say NO!) -------------------+-----------------------+------------------------------------
