that Bruce asked for.
These still are not quite perfect, and in particular, it can get
upset on extreme boundary cases (addr = 0xfff, len = 0xffffffff,
which would end up mapping a single page rather than failing), but
this is better code that I committed before.
(note, the VM system does not (apparently) support single mmap segment
sizes above 0x80000000 anyway)
the S-Video input. It also has code in the driver for the meteor RGB support
and some other bug fixes. I don't have a meteor RGB but I have been told
that it works.

queue type is not set to QUEUE_NONE. This appears to have
caused a hang bug that has been lurking.
2) Fix bugs that brelse'ing locked buffers do not "free" them, but the
code assumes so. This can cause hangs when LFS is used.
3) Use malloced memory for directories when applicable. The amount
of malloced memory is seriously limited, but should decrease the
amount of memory used by an average directory to 1/4 - 1/2 previous.
This capability is fully tunable. (Note that there is no config
parameter, and might never be.)
4) Bias slightly the buffer cache usage towards non-VMIO buffers. Since
the data in VMIO buffers is not lost when the buffer is reclaimed, this
will help performance. This is adjustable also.
- split driver into FreeBSD specific and camera specific portions
(qcamio.c can run in user mode, with a Linux "driver top" etc,
and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
stuff has been pulled out for the moment to make it easier to debug)
At this point, anyone who wants to port it to other platforms should feel
free to do so. Please feed changes directly back to me so that I can produce
a unified distribution.
messy 130 column collage, output the system totals -or- info for a
specific interface if -I is given. Also wait for <interval> before
outputting the first sample so that it represents meaningful data (as
opposed to the total since the system was booted - most busy systems
wrap around many times during their operation, so these numbers are
only misleading).
doesn't break support for the older models (tested with my 3C589B).
