ttwwakeup(). The conditions for doing the wakeup will soon become
more complicated and I don't want them duplicated in all drivers.
It's probably not worth making ttwwakeup() a macro or an inline
function. The cost of the function call is relatively small when
there is a process to wake up. There is usually a process to wake
up for large writes and the system call overhead dwarfs the function
call overhead for small writes.
(a) bring back ttselect, now that we have xxxdevtotty() it isn't dangerous.
(b) remove all of the wrappers that have been replaced by ttselect
(c) fix formatting in syscons.c and definition in syscons.h
(d) add cxdevtotty
NOT DONE:
(e) make pcvt work... it was already broken...when someone fixes pcvt to
link properly, just rename get_pccons to xxxdevtotty and we're done
(b) add a function callback vector to tty drivers that will return a pointer
to a valid tty structure based upon a dev_t
(c) make syscons structures the same size whether or not APM is enabled so
utilities don't crash if NAPM changes (and make the damn kernel compile!)
(d) rewrite /dev/snp ioctl interface so that it is device driver and i386
independant
<string.h> isn't supposed to be used by the kernel.
cronix.h is <machine/cronix.h>, not "cronyx.h" (ambiguous) or
<sys/cronyx.h> (nonexistent; caused compile to fail).
cxreg.h is <i386/isa/cxreg.h>, not "cxreg.h".
<i386/isa/cpufunc.h> shouldn't be included directly; it is always
included by <sys/systm.h>.
<i386/include/*.h> is <machine/*.h>
<systm.h> is <sys/systm.h>.
<kernel.h> is <sys/kernel.h>.
<bpfilter.h> is "bpfilter.h". It really is in the current directory.
