tsutsui 8d11ba186d Add some delays between 8bit reads of DSTAT and SSTAT0 registers 
as per the 53c710 manual. Pointed out by fredette in osiop_gsc.c long ago.

bouyer e5727031fb Implement mstohz() as discussed on tech-kern, and use it in SCSI drivers 
to convert xs->timeout to callout() parameter.

thorpej 623f83a793 Use BUS_DMA_READ and BUS_DMA_WRITE in some obvious places. 2001-07-19 16:25:23 +00:00

Pointed out by soda.

scw d1bc67e029 In osiop_scsidone(), call scsipi_done() even for polled operations. 
This fixes a `hang' on shutdown when the `Synchronise Cache' command
is sent to a disk. (It uses polled mode because it is called from inside
a shutdown hook).

tsutsui 330ab2b636 Print a clock frequency of the chip. 2001-05-09 16:24:43 +00:00
tsutsui 613923b42e Add a MI driver for the Symbios/NCR 53c710 SCSI controller. 
This is based on amiga's siop driver, but converted to use
bus_space(9) functions and modified to fit bus_dma(9) framework.

Currently tested on NetBSD/arc with jazzio 53c710 SCSI,
which really requires bus_dma(9) functions :-)
Sync transfers and disconnect/reconnect are also working.

TODO:
- Test under more heavy load
- Clean up osiop_checkintr() hander
- Reorganize command queue and sync negotiation handling more suitable
  for thorpej-scsipi mid-layer
- Re-think defered interrupt handling for amiga
