2 reasons:
-no need to keep a list of all known parts
-there is at least 1 bridge (ACC micro 2051) which reports the same
device ID for its various subfunctions; this would require an additional
check in the match function
(keep the old list inside #if 0 in case one of the historical bridges
doesn't report the right class/subclass - I can't check them all)
the /dev/rmidiN devices, or with a sequencer interface via /dev/music.
So far the only supported MIDI device is the MPU401 port on SoundBlaster
(and only on SB on isapnp, since we do not have locators with multiple
values yet).
fix last two fixes one more time, this time dealing with ugly
prototype issues, including the fact that the bcopy returns nothing,
but memcpy returns a void *. Never mind that we don't use it...
This was semi-nontrivial, since a function pointer to bcopy gets used
in this file.
Note #1: The catchpacket routine, which takes a function pointer to
bpf_mcpy or memcpy, should probably be converted to take a
flag that just says which is used, so memcpy can be inlined.
Note #2: The code is heavily #ifdef'ed to run on older operating
systems. We probably want to clean that cruft out, unless
someone is planning a new release of the code at LBL (doubtful.)
-store printable product ID in cd's and sd's softc, use it as "typename"
-for this, add a "destination buffer length" argument to scsipi_strvis()
-return ATAPI device type for ATAPI devices
clock past the End of Time.
If time_t is 32 bits, then the "End of Time" is Jan 18/19 2038
(depending on time zone).
This code copes with RTC's past the end of time if time_t is an int32
or less. It just forces the time back to 2037. This will let users
with screwed up clocks to at least boot and function long enough to
set their clocks to something sane.
This kludge is conditioned on an
if (sizeof(time_t) <= sizeof(int32_t))
which will automatically optimize the code out once we switch time_t
to a 64 bit quantity, which should happen well before 2037.
Patch based on code from Michael C. Richardson, with help from
Allen Briggs who pointed out a fencepost error.
The cache cleaning code in pmap_copy_page() and pmap_zero_page()
has been rewritten and uses a new function pmap_clean_page().
pmap_remove() has been completely rewritten to make it more efficient
when there are only a few pages that actually need to be removed.
