XID confusions with servers that cache them over a long period and
with clients that reboot quickly.
Problems: because of the sanity check that is done by comparing the system
time with filesystem time, XIDs will start at 0 until root is mounted,
which means it isn't completely safe for diskless setups. But it's clearly
better than it was. It would also be cleaner if all XID handling (more
generally, all RPC handling) within the kernel went through the
same functions.
matic media detection on Sun4m machines which support multiple media
(UTP and AUI). New function lenocarrier() switches media type when called
if no link? flags are set.
Redefine link flags for Lance ethernet (le):
<none>: switch between media as needed to find carrier (autodetect)
Preference to whatever the PROM is using (AUI if not booted
from the network)
link0: use UTP port only
link1: use AUI port only
This allows Sun4m machines with dual media Lance ethernet adapters to
boot from the network on the UTP port.
function is called when carrier is lost in lieu of a console message.
This is used by the sparc port to switch media types on Sun4m machines
if the appropriate link flags are set by ifconfig (see following commit
message). Should not affect ports that do not use sc_nocarrier().
we managed to kill the following SCSI-driver bugs for the Falcon:
- The Byte_Count_zero bit of the falcon DMA controller does not always
tell the truth! This caused the SCSI-driver to choke on devices that
disconnected in the middle of a DMA-transfer (mostly removables).
- Printing debug info about the 5380 on the Falcon is *only* permitted
when DMA is not active.
- Some functions forgot to remove possibly pending sofware interrupts
- Some debug options didn't allow debugging a single target while they
could easily be made to do so. This is fixed.
from the mach3 versions only as much as necessary to allow the old
NetBSD/Alpha pmap code to compile. THESE WILL NOT WORK AS-IS, and at
minimum will require code to implement reference- and modified-bit
emulation.
All Unibus dependencies are removed.
Can support different controllers on different buses.
Allows cloning of devices.
TODO:
Write support for MSCP tapes.
old config anymore, all devices should use new config by now.
Add structures to handle DMA devices using new config.
Fixed bug that caused unwanted ubareset's on 11/780.
Use new ldda() and stda() to make MultiCache initialization work on
SuperSparc-II machines (these machines require 64-bit access, even
to a 32-bit register).
