and non-const types, and the kernel uses both const and non-const
PMF qualifiers and device suspensors, so change the pmf_qual_t and
device_suspensor_t typedefs from "pointers to const" to non-pointer,
non-const types.
#if NBPFILTER is no longer required in the client. This change
doesn't yet add support for loading bpf as a module, since drivers
can register before bpf is attached. However, callers of bpf can
now be modularized.
Dynamically loadable bpf could probably be done fairly easily with
coordination from the stub driver and the real driver by registering
attachments in the stub before the real driver is loaded and doing
a handoff. ... and I'm not going to ponder the depths of unload
here.
Tested with i386/MONOLITHIC, modified MONOLITHIC without bpf and rump.

XXX: sparc/dev/cgthree.c in Attic had an attachment for cgthree* at obio?
XXX: and sparc/conf/files.sparc still has an entry of nonexistent (or not yet)
XXX: sparc/dev/cgthree_obio.c. Is there any sun4m machine which requires it?
They are derived from 4.4BSD/sparc and have been there since initial import
of NetBSD/sparc in 1993, but the struct sbusdev is almost unused for years,
nothing calls sbusreset(), and all (*sd->sd_reset)() functions look bogus.
Suggested by mrg@ and martin@, and tested on SS1+ and SS20.
with possible orphaned this le at sbus one on old PROMs not using
homegrown struct sbusdev but common cfdriver_t and device_t structures.
Now nothing refers struct sbusdev registered by sbus_establish().
Tested an SBus le/esp combo card on SS1+.
not device_t parent even if sbus is grandparent of the device,
otherwise (*sd_reset)() callbacks will be called with an wrong device_t.
Even in such case, sbus_establish() looks for an sbus though device tree.
XXX: (*sd_reset)() isn't called anyway, and these stuff seems really bogus.
registration of (*sd_reset)(device_t) in struct sbusdev via sbus_establish().
XXX: (*sd_reset)() in struct sbusdev seems called from only sbusreset(),
XXX: but there is no function which calls sbusreset()???
- add support for screen blanking via /dev/fb*
- reimplement colour map ioctl()s for /dev/fb*
- implement mmap and ioctl for wscons, map 8 or 24bit framebuffer depending
on hardware
With this X works with the wsfb driver in 24bit.
TODO:
- fix wsfb to use the right pixel format for S24
- implement wsdisplay colour map ioctl()s
- add hardware cursor support for wscons and /dev/fb*
- attach a wsdisplay
- make it work with an S24
- accelerate scrolling and character drawing
This isn't quite finished yet, it works fine as a console but most things
X will need are not functional right now.
not finished the device_t/softc split for the SBus attachment
because I don't have an SBus gem(4) to test with.
Convert from legacy shutdownhooks to a PMF shutdown hook. Add PMF
suspend/resume handlers.
Factor a detachment hook out of gem_attach(). During device
attachment, track which resources are reserved in sc_attach_state,
and release only those resources during detachment.
Tested on gem0 and gem1 at pci1 on a Sun Fire V120.
