695805a585 Remove tinfo_t which would have been a typedef had someone actually used 
typedef but instead it become an unused common.

529e91fca1 struct device * -> device_t, no functional changes intended. 2009-05-12 14:16:35 +00:00

0e95582ed1 WD33C93 has only two registers, which often times aren't mapped to adjacent 
bus space locations. Map them individually, instead.

11aab16b02 Split device_t from wd33c93_softc. Reviewed by cube; tested on sgimips 
by tsutsui.

b1a93d335f Fix comments about the cf_flags layout and use macros to test whether 
tags, sync, and disconnect/reconnect are to be disabled or not.

11dc14c9fe Enable Fast SCSI transfers for WD33C93B parts with appropriate input 
clocks.

My Seagate ST32430N now sees about 50% greater throughput (about 97% as
fast as IRIX can push it). However, there appear to be other performance
issues with the driver as other disks perform significantly worse than they
should, with or without this change.

Reviewed by bjh21. Tested on my Indy and Challenge S.

53524e44ef Kill caddr_t; there will be some MI fallout, but it will be fixed shortly. 2007-03-04 05:59:00 +00:00

439213ef2c Allow wd33c93 attachments to choose what DMA mode it should use, and arrange 
to use burst mode on sec(4), which makes it slightly but significantly faster.

24bcb8e38a wd33c93_minphys() doesn't exist any more, so don't declare it. 2006-09-26 23:27:36 +00:00

334ef0cbc9 Merge my bjh21-wd33c93 branch. This improves message handling in general 
and sync negotiation in particular.  Tested on sgimips (thanks to
Manuel Bouyer) and acorn26 (with my still-unfinished driver for the Acorn
SCSI Expansion Card).

2cd3c4f0e6 Move the sgimips "sbic" driver from arch/sgimips/hpc/sbic.c to 
dev/ic/wd33c93.c.  This may not be the best WD33C93 driver we've
got, but it's the most recently worked on and probably the most
portable, so it seems like a good basis for further work (and in
particular an acorn26 driver for the Acorn SCSI card).  There's
no functional change in this commit, and sgimips kernels still
compile.
