Subject: ide driver - where do i start?
Date: Fri, 07 Jul 2000 10:15:18 +1200 [thread overview]
Message-ID: <396504F6.8C36D79C@m2tech.co.nz> (raw)
hello all!
listen, we are using a ppc 403gcx running at 80 mips, and have connected
an ide drive straight up to the data bus (through some buffers)..
i can look at the driver command/control registers fine as memory mapped
i/o, etc.. the hd is dma-able and the interface is setup to be stable at
pio4 possibly udma/33..
the next step for me is to modify the linux ide code to talk to my
drive.. has anyone hooked up ide directly to the processor bus?? i am
currently looking at basing my code off drivers/block/ide-pmac.c and
changing the probe and dma code to fit.. is this the place to start??
cheers for any insights,
--
