TURBOchannel expansion bus driver
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

The tc
driver first appeared in NetBSD
1.1.
The tc
driver makes poor use of interrupt priority on
the 5000/1xx series systems.
