Now that the new sound code supports MIDI, the major reason we had for
reviving it is gone. It is a far better investment polishing the new

there are major shortcomings in the pcm sound driver then maybe we can
rethink this, but until then we should focus on pcm.

Previously, these cards were supported by the lnc driver (and they
still are, but the pcn driver will claim them first), which is fine
except the lnc driver runs them in 16-bit LANCE compatibility mode.
The pcn driver runs these chips in 32-bit mode and uses the RX alignment
feature to achieve zero-copy receive. (Which puts it in the same
class as the xl, fxp and tl chipsets.) This driver is also MI, so it
will work on the x86 and alpha platforms. (The lnc driver is still
needed to support non-PCI cards. At some point, I'll need to newbusify
it so that it too will me MI.)
The Am79c978 HomePNA adapter is also supported.
The code for suspend/resume is derived from APM device driver.
Some people suggested the original code is somewhat buggy, but I'd

the gating of system calls that cause modifications to the underlying
filesystem. The gating can be enabled by any filesystem that needs
to consistently suspend operations by adding the vop_stdgetwritemount
to their set of vnops. Once gating is enabled, the function
vfs_write_suspend stops all new write operations to a filesystem,
allows any filesystem modifying system calls already in progress
to complete, then sync's the filesystem to disk and returns. The
function vfs_write_resume allows the suspended write operations to
begin again. Gating is not added by default for all filesystems as
for SMP systems it adds two extra locks to such critical kernel
paths as the write system call. Thus, gating should only be added
as needed.

TODO:
MSS/PCI bridge drivers
Midi-tty interface to support general serial devices
Modules
Currently, many drivers support more than one bus of ISA, EISA, MCA,
PCI.
Before this commit, we had, for example, some SCSI devices listed more
than once, iirc, some up to three times (ISA/EISA, MCA, PCI).
Since now the "device" line is common for all of them and they only
differ for the hints stuff, I did the following:
First, list Busses: (E)ISA, MCA, PCI and explain, that only ISA
needs the hints stuff.
Move NIC/SCSI stuff, which were the only split sections, behind these
stuff. Describe all drivers only one time and list all supported
chips.
List all device (+ hints for ISA, if possible).
I've also added few additional supported chips to some drivers, xl for
example and some SCSI drivers.
Also, softupdates is no longer disabled by default, so the comment should
not say, it's not enabled by default due to license issues.

This means 'options NETGRAPH' is no longer necessary in order to get
netgraph-enabled Ethernet interfaces. This supports loading/unloading
the ng_ether.ko and attaching/detaching the Ethernet interface in any
order.
Add two new hooks 'upper' and 'lower' to allow access to the protocol
demux engine and the raw device, respectively. This enables bridging
to be defined as a netgraph node, if so desired.

implying that they aren't used for the rest of the system.
Fix the lies:
253 is used by mfs (bad MFS for not registering it).
254 is a magic cookie inside of the dev code in at least one place.
255 is -1 which is magic in a different way in the dev code.
So, that means that 200-252 are reserved for local users. A grep for
252 didn't turn anything up, so I'm assuming it and lower are safe.
And I thought I was being smart by allocating our local major numbers
from 254 on down. This caused very very odd problems that were hard
to track down: close not being called, sync failing at reboot, etc.

Use Warner Losh's "hint" driver to decode ascii strings to fill the
resource table at boot time.
config(8) no longer generates an ioconf.c table - ie: the configuration
no longer has to be compiled into the kernel. You can reconfigure your
isa devices with the likes of this at loader(8) time:
set hint.ed.0.port=0x320
userconfig will be rewritten to use this style interface one day and will
move to /boot/userconfig.4th or something like that.
It is still possible to statically compile in a set of hints into a kernel
if you do not wish to use loader(8). See the "hints" directive in GENERIC
as an example.
All device wiring has been moved out of config(8). There is a set of
helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98)
that extract the 'at isa? port foo irq bar' from the old files and produces
a hints file. If you install this file as /boot/device.hints (and update
/boot/defaults/loader.conf - You can do a build/install in sys/boot) then
loader will load it automatically for you. You can also compile in the
hints directly with: hints "device.hints" as well.
There are a few things that I'm not too happy with yet. Under this scheme,
things like LINT would no longer be useful as "documentation" of settings.
I have renamed this file to 'NOTES' and stored the example hints strings
in it. However... this is not something that config(8) understands, so
there is a script that extracts the build-specific data from the
documentation file (NOTES) to produce a LINT that can be config'ed and
built. A stack of man4 pages will need updating. :-/
Also, since there is no longer a difference between 'device' and
'pseudo-device' I collapsed the two together, and the resulting 'device'
takes a 'number of units' for devices that still have it statically
allocated. eg: 'device fe 4' will compile the fe driver with NFE set
to 4. You can then set hints for 4 units (0 - 3). Also note that
'device fe0' will be interpreted as "zero units of 'fe'" which would be
bad, so there is a config warning for this. This is only needed for
old drivers that still have static limits on numbers of units.
All the statically limited drivers that I could find were marked.
Please exercise EXTREME CAUTION when transitioning!
