proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:
- Inspecting process state requires thread context, so signals can no longer
be sent from a hardware interrupt handler. Signal activity must be
deferred to a soft interrupt or kthread.
- As the proc state locking is simplified, it's now safe to take exit()
and wait() out from under kernel_lock.
- The system spends less time at IPL_SCHED, and there is less lock activity.
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.

Fill in band switch crosspoints and use that instead of hardcoded
values in the band switching code. For now fill in the formerly
hard-coded values 160 and 454 until we can find out the real values
for each tuner. Also make those variables int instead of char
so it can actually hold 454...
when setting CARD_LEADTEK. now with just
options BKTR_SYSTEM_DEFAULT=BROOKTREE_PAL
i get a shiny happy working card on my macppc box:
bktr0 at pci1 dev 18 function 0
bktr0: interrupting at irq 52
bktr0: Leadtek WinFast TV2000/VC100, Philips FR1216 PAL FM tuner.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
Changes since last import:
. lots of whitespace cleanups
. typo fixes (e.g. hz, compatibilty)
. fix brightness ioctl return value
. wait for int ready using DELAY() instead of tight loop
Uploaded scripts work better if they are little endian, as the
card's engine expects, so convert to le first.
Also clean up attach routine a bit (use pa_id and PCI_REVISION
instead of fetching it ourselves).
This makes the driver work on my macppc G4, it can decode and
display video and tuner input. Sound does not seem to work, but
this may be my wonky formac bktr-for-macintosh card.
