Thanks to a donation of a MVME177
to the NetBSD Foundation by Matt Thomas, Steve Woodford has been able
to complete the support for this m68060-based board in NetBSD/mvme68k
Accordingly, Steve has made available a new NetBSD/mvme68k snapshot,
based on 2001-08-07 -current sources. It is available in the NetBSD/mvme68k
area of the ftp server.
Since the last -current snapshot, a number of notable changes have made
it into the NetBSD/mvme68k kernel:
- The MI evcnt(9) interface is now used to record interrupt statistics.
- The standalone netboot program now supports DHCP in addition to
- `Simulated' software interrupts have been replaced by real `hardware
assisted' software interrupts. This reduces the amount of overhead
on exit from exception handlers.
- Numerous pmap tweaks to improve reliability.
- The ECC DRAM controller(s) on MVME167/MVME177 (and optional on
MVME162/MVME172) are now fully enabled. The kernel will now detect
and log any errors reported by the controllers. You may need to change
your kernel config files, as the memc(4) driver now attaches at mainbus0
instead of pcctwo0. Note that the memc(4) driver does not yet support
the MEMC040 parity checking memory controllers found on some boards.
- And, of course, completed MVME177 support.
As usual, if you experience any problems, please report them using
send-pr(1) and/or the port-mvme68k
