products claim they emulate the PS/2 mouse when the host computer
talks to the mouse while the mouse is actually routed to another
host.
flags 0x200 Do not try to identify the mouse model. All
mice will be recognized as "generic PS/2".
0x400 Do not reset the mouse. Some switches' response
to the reset command is too slow and the psm
will timeout.
0x1000 Relax error checking when probing the mouse
port.

flags 0x800 Assume the pad behaves like ALPS GlidePoint
when the user `taps' the surface of the pad;
it will be reported as the fourth button.
# `moused' is getting too over-loaded now. If we want something
# more than simple mouse emulation for tablets or remote devices,

the first time block 0 is read. This fix initialises the block
numbers to -1 which isn't the most correct thing for a daddr_t but
it isn't likely to cause a problem in the boot blocks and it could
do with a more thought out fix later.
The bug is probably benign on the i386 but on the alpha it can
cause initial file opens to fail. This is the cause of the "can't
open /boot/boot.conf" errors.
It appears on the alpha because of a number of combining factors.
On the alpha the LABELSECTOR is 0 so block 0 needs to be read in
from the media. The first time this happens you get a false hit
because the bc_blkno field is zero initially. Also, the timestamp
check against this cache hit succeeds because on the alpha a hacked
getsecs() function can return 0 when it starts counting so that
the zero initial timestamp + BCACHE_TIMEOUT is greater than the
current time until getsecs() has counted passed BCACHE_TIMEOUT.
The overall effect is that the first open() that occurs gets a
false cache hit and returns garbage to the bd_strategy() function
which then fails the open() call. This false hit then stays in the
cache until BCACHE_TIMEOUT getsecs() ticks have passed; all open()
calls during this time fail.
This explains why you can generally access the media by the time
you get to interp() and start issuing commands but the earlier
attempts to run the boot scripts are failing.
It's possible that this is causing the problem switching to the
mfsroot floppy as well but I haven't confirmed that.
almost always causes this panic for the curproc != pageproc case.
This case apparently doesn't happen in normal operation, but it
happens when vm_page_alloc_contig() is called when there is a memory
hogging application that hasn't already been paged out.

I also changed the transmit encapsulation routine to always to

anyway. I also tweaked the code that pads packets out to the minimum

scheme of things, but it makes me feel better.

cache. If the cached result lets us say "yes", then go with that. If
we're not sure, or we think the answer might be "no", go to the wire to be
certain. This avoids all of the possible false veto cases, and allows us
to key the cached value with just the UID for which the cached value holds,
reducing the bloat of the nfsnode structure from 104 bytes to just 12 bytes.
Since the "yes" case is by far the most common, this should still provide
a substantial performance improvement. Also default the cache to on, with
a conservative timeout (2 seconds). This improves performance if NFS is
loaded as a KLD module, as there's not (yet) code to parse an option out
of the module arguments to set it, and sysctl doesn't work (yet) for OIDs
in modules.

Feedback on this would be appreciated as testing has been necessarily
limited by Comdex, and it would be valuable to have this in 2.2.8.
* Update drivers to the latest version of the bus interface.
The ISA drivers' use of the new resource api is minimal. Garrett has
some much cleaner drivers which should be more easily shared between
i386 and alpha. This has only been tested on cia based machines. It
should work on lca and apecs but I might have broken something.

devstart_start_transaction() call is misplaced - it is after the
wdustart() call that queues the transaction on the controller queue.
Normally this doesn't matter because we're running at splbio() so
nothing will look at the controller queue. However, obsolescent
code for syncing labels sometimes slept after the transaction was
started, so the transaction sometimes completed before it was
[recorded as] started. This code was misplaced even for syncing
labels. Move it to the right place. It should go away, but
something may depend on its side effects.
- Interface wth the new resource manager.
- Allow for multiple drivers implementing a single devclass.
- Remove ordering dependencies between header files.
- Style cleanup.
- Add DEVICE_SUSPEND and DEVICE_RESUME methods.
- Move to a single-phase interrupt setup scheme.
Kernel builds on the Alpha are brken until Doug gets a chance to incorporate
these changes on that side.
