tcTURBOchannel expansion bus driver

tc* at tcasic?

The tc driver provides machine-independent support for the DEC TURBOchannel expansion bus found on all DEC 5000-series machines with MIPS, DEC 3000-series with Alpha processors and VAXstation 4000 machines with the optional TURBOchannel adaptor.

Your system may support additional TURBOchannel devices. Drivers for TURBOchannel devices not listed here are machine-dependent. Consult your system's intro(4) for additional information.

NetBSD includes machine-independent TURBOchannel drivers, sorted by device type and driver name:

asc
PMAZ-A single-channel SCSI adapter
tcds
PMAZ-DS, PMAZ-FS, PMAZB-AA and PMAZC-AA dual-channel SCSI adapters

fta
PMAF-F DEFTA FDDI controller
le
LANCE Ethernet interface

cfb
PMAG-B CX colour unaccelerated 2-D framebuffer
mfb
PMAG-A MX monochrome framebuffer
px
PMAG-C PX accelerated graphics boards
pxg
PMAG-D, PMAG-E and PMAG-F PXG accelerated graphics boards
sfb
PMAGB-BA HX colour unaccelerated 2-D framebuffer
tfb
PMAG-J TX 24-bit colour unaccelerated 2-D framebuffer

ioasic
baseboard IO control ASIC for DEC TURBOchannel systems
tcu
TC-USB USB host and GPIO option

The tc driver first appeared in NetBSD 1.1.

The tc driver makes poor use of interrupt priority on the 5000/1xx series systems.
