07076ce1f7 Bump the buffersize from 0x1000 to 0x4000. 
0x1000 gets underflows on my dell 7500 whenever I moved the mouse.
(reported as "hwptr went backwards...", with jumpy sound)
Sounds great now....

46aa3347cb Convert all users of fldoff() to offsetof(). fldoff() is bad 
because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.

Define __offsetof() in <machine/ansi.h>

Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>

Remove myriad of local offsetof() definitions.

Remove includes of <stddef.h> in kernel code.

NB: Kernelcode should *never* include from /usr/include !

Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.

Deprecate <struct.h> with a warning.  The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

Poul-Henning Kamp
db90128160 Avoid the modules madness I inadvertently introduced by making the 
cloning infrastructure standard in kern_conf.  Modules are now
the same with or without devfs support.

If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".

This happily removes an ugly hack from kern/vfs_conf.c.

This forces a rename of the eventhandler and the standard clone
helper function.

Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>

Remove all #includes of opt_devfs.h they no longer matter.

0edeb3dc90 A couple of cosmetic fixes, plus a biggie: When checking the DMA 
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
for business.

05a1fdb459 Simplex devices will always report EBUSY on 2nd (and subsequent) 
opens if the reference count is not decremented on close.

Note that this may result in the reference count being corrupted
on full duplex devices (due to mismatching opens/closes), but the
code doesn't use the reference count for anything on full duplex
devices.

3ac1ca3363 1. Increase the size of the DMA buffer. 
2. Offer half duplex with both playback and record on channel 1 or

19a0702e86 Get playback on channel 1 closer to working. 8 bit samples work. 
16 bit samples have some sort of choppiness, the nature of which
is not completely clear, but it clearly has something to do with
dma buffer synchronization. But at least channel 1 makes noise now.

8eb3acc9be Fix channel 1, sort of. recording now generates IRQs and the output 
appears to be the correct length, but quality of output has not yet

does not yet work. Two constants and I am there!

/dev/midistat now reports installed midi drivers. /dev/sndstat reports
only pcm drivers. We need the new name(pcmstat?).

9626b608de Separate the struct bio related stuff out of <sys/buf.h> into 
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.
