and use appropriately
- create more helper macros:
. cdev__xyz_init(c,n), such as cdev__ocri_init() for
/* open, close, read, ioctl */, etc.
. cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
method `R' and the comments now read /* xxx (read) yyy */ instead
. cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
as well
- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
always DTRT WRT returning a valid result. (a few devices previously
incorrectly returned ENODEV)
- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
== 0, because it doesn't matter if dev_type_stop isn't implemented in that
case, and it allows the use of the cdev__xyz_init macros. certain ports
(sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
drivers, whereas everything else uses enodev
- ensure that the comments are accurate WRT the behaviour of a given entry
and place the definition in <machine/types.h>. This can now be used
as a flag to indicate whether or not <machine/intr.h> can be included
to get the generic soft interrupt API.
