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:
- tcds(4)
- PMAZ-DS, PMAZ-FS, PMAZB-AA and PMAZC-AA dual-channel SCSI adapters
- le(4)
- LANCE Ethernet interface
- cfb(4)
- PMAG-B CX colour unaccelerated 2-D framebuffer
- mfb(4)
- PMAG-A MX monochrome framebuffer
- px(4)
- PMAG-C PX accelerated graphics boards
- pxg(4)
- PMAG-D, PMAG-E and PMAG-F PXG accelerated graphics boards
- sfb(4)
- PMAGB-BA HX colour unaccelerated 2-D framebuffer
- tfb(4)
- PMAG-J TX 24-bit colour unaccelerated 2-D framebuffer
- ioasic(4)
- baseboard IO control ASIC for DEC TURBOchannel systems
- tcu(4)
- 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.
