there should be no functional impact.
Remove old DEVFS support fields from dev_t.
Make uid, gid & mode members of dev_t and set them in make_dev().
Use correct uid, gid & mode in make_dev in disk minilayer.
Add support for registering alias names for a dev_t using the
new function make_dev_alias(). These will show up as symlinks
in DEVFS.
Use makedev() rather than make_dev() for MFSs magic devices to prevent
DEVFS from noticing this abuse.
Add a field for DEVFS inode number in dev_t.
Add new DEVFS in fs/devfs.
Add devfs cloning to:
disk minilayer (ie: ad(4), sd(4), cd(4) etc etc)
md(4), tun(4), bpf(4), fd(4)
If DEVFS add -d flag to /sbin/inits args to make it mount devfs.
Add commented out DEVFS to GENERIC
that should be better.
The old code counted references to mbuf clusters by using the offset
of the cluster from the start of memory allocated for mbufs and
clusters as an index into an array of chars, which did the reference
counting. If the external storage was not a cluster then reference
counting had to be done by the code using that external storage.
NetBSD's system of linked lists of mbufs was cosidered, but Alfred
felt it would have locking issues when the kernel was made more
SMP friendly.
The system implimented uses a pool of unions to track external
storage. The union contains an int for counting the references and
a pointer for forming a free list. The reference counts are
incremented and decremented atomically and so should be SMP friendly.
This system can track reference counts for any sort of external
storage.
Access to the reference counting stuff is now through macros defined
in mbuf.h, so it should be easier to make changes to the system in
the future.
The possibility of storing the reference count in one of the
referencing mbufs was considered, but was rejected 'cos it would
often leave extra mbufs allocated. Storing the reference count in
the cluster was also considered, but because the external storage
may not be a cluster this isn't an option.
The size of the pool of reference counters is available in the
stats provided by "netstat -m".

understand exactly what it is about SMPng that tickles this bug. What I
do know is that the foo_init() routine in most drivers is often called
twice when an interface is brought up. One time is due to the ifconfig(8)
command calling the SIOCSIFFLAGS ioctl to set the IFF_UP flag, and another
is probably due to the kernel calling ifp->if_init at some point. In any
case, the SMPng changes seem to affect the timing of these two events in
such a way that there is a significant delay before any packets are sent
onto the wire after the interface is first brought up. This manifested
itself locally as an SMPng test machine which failed to obtain an address
via DHCP when booting up.
It looks like the second call to fxp_init() is happening faster now than
it did before, and I think it catches the chip while it's in the process
of dealing with the configuration command from the first call. Whatever
the case, a FXP_CSR_SCB_CNA interrupt event is now generated shortly after
the second fxp_init() call. (This interrupt is apparently never generated
by a non-SMPng kernel, so nobody noticed.)
There are two problems with this: first, fxp_intr() does not handle the
FXP_CSR_SCB_CNA interrupt event (it never tests for it or does anything
to deal with it), and second, the meaning of FXP_CSR_SCB_CNA is not
documented in the driver. (Apparently it means "command unit not active.")
Bad coder. No biscuit.
The fix is to have the FXP_CSR_SCB_CNA interrupt handled just like the
FXP_SCB_STATACK_CXTNO interrupt. This prevents the state machine for
the configuration/RX filter programming stuff from getting wedged for
several seconds and preventing packet transmission.

This is done by misusing the device minor a bit to encode the
track no there.
So to read track #4 just use /dev/acdNt4 where N is the device #.
The driver no automatically sets the blocksize (sectorsize) to
what the track is set to in the TOC.
This has the nice effect that you can now rip audioi tracks
by simply doing:
dd if=/dev/acdNt2 of=audiotrack2.raw bs=2352
it cant be much simpler than that :)
NOTE: the original acdNa & acdNc device still work as usual,
except the blocksize is set according to track0.

position, channel 1's dma position register must be quiescent. So
the driver will spl, pause the DMA, delay a bit and hold as still as
possible while snapping the picture.
I'm sure there HAS to be a better way to do this, but if there is, it's
not documented.
So far as I can tell, this fixes recording, which means the Solo is open
