(I am sorry this is similar to a separate post to comp.os.linux.hardware,
where it is getting no responses. I should have cross-posted at once)
I want to move data by DMA from a SCSI drive raw partitions, using AIC-7899
SCSI controller to certain physical memory addresses, under Linux kernel
2.2.18. The DMA bursts should be large and should end on a 256-byte
boundary, so you see I want to have fine control over the transfers.
I don't think this can be directly done with the Linux standard distribution
driver for AIC-7899, so I think I may have to modify the driver, but I am
Can/should the AIC-78xx driver in the standard Linux kernel be used for
If we have to modify the driver, how to get documentation for that Adaptec
AIC-7899? We have it on the Intel motherboard, but both Adaptec and Intel
are refusing any detailed documents. What documentation was used to write
the Linux driver in the standard distribution??
By the way, this is for a wonderful non-for-profit project: the new
