better. I'm surprised that disabling interrupts helped much. Disabling
them in the packet receive routine is too late.
Fixed some minor style bugs in rev.1.14.
to fetch the magic word instead of useracc() plus a direct access.
This is more efficient as well as simpler and less incorrect:
- it was inefficent because useracc() takes much longer than just
accessing the data using a correct access method, at least on i386's.
- it was incorrect because direct access is incorrect unless the address
has been mapped. This and nearby direct accesses are mostly handled
better for other arches because they have to be (direct accesses don't
work).
- using magic in sigreturn is still fundamentally broken because false
matches are possible. On i386's, a false match occurs when %eip in a
new signal context happens to equal the magic value. This is not
handled better for other arches.
npx is no more mandatory than sc. Its mandatoryness went away in
rev.1.226 of i386/machdep.c 9 months before it was made mandatory in
rev.1.24 of config/mkmakefile.c.
This change is mainly to test building of minimal kernel configurations.
npx should really be even more standard than clk. It was optional mainly
so that the usual device driver configuration info could be specified in
the usual way in config files, but this hasn't been necessary for a few
years.
is not configured. Including <isa/isavar.h> when it is not used is
harmful as well as bogus, since it includes "isa_if.h" which is not
generated when isa is not configured.
This was fixed in 1999 but was broken by unconditionalizing PNPBIOS.
other threads as well as speed up the interfaces.
To fix the race and accomplish the speedup, remove selholddrop and
pollholddrop. The entire concept is somewhat bogus because holding
the individual struct file pointers offers us no guarantees that
another thread context won't close it on us thereby removing our
access to our own reference.
Selholddrop and pollholddrop also would do multiple locks and unlocks
of mutexes _per-file_ in the fd arrays to be scanned, this needed to
be sped up.
Instead of using selholddrop and pollholddrop, simply hold the
filedesc lock over the selscan and pollscan functions. This should
protect us against close(2)'s on the files as reduce the multiple
lock/unlock pairs per fd into a single lock over the filedesc.
to ExCA register sets. These registers exist in both ISA and PCI
devices in a couple different ways, and this will provide a common
base for future building. This code is a rehash of the pccbb 16-bit
code, which was a rehash of the pcic code, which was a rehash of the
netbsd i82365 code. More hashing to come.
interfaces we encounter. In Linux, all addresses are returned for
which gifconf handlers are installed. This boils down to AF_DECnet
and AF_INET. We care mostly about AF_INET for now. Adding additional
families is simple enough.
Returning the addresses is important for RPC clients to function
properly. Andrew found in some reference code that the logic that
handles the retransmission looks for an interface that's up and has
an AF_INET address. This obviously failed as we didn't return any
addresses at all.
Note also that with this change we don't return interfaces that don't
have AF_INET addresses, whereas before we returned any interface
present in the system. This is in line with what Linux does (modulo
interfaces with only AF_DECnet addresses of course :-)

64-bit platforms. The unaligned access is caused by struct ifa_msghdr
not being a multiple of 8-bytes in size. If an interface has an odd
number of addresses, this causes the next interface to generate an
unaligned access in the user-level app walking the interfaces (ifconfig).

which small and/or nearly full filesystems would fail with `file
system full' messages when trying to replace a number of existing
files (for example during a system installation). When the allocation
routines are about to fail with a file system full condition, they
make a call to softdep_request_cleanup() which attempts to accelerate
the flushing of pending deletion requests in an effort to free up
space. In the face of filesystem I/O requests that exceed the
available disk transfer capacity, the cleanup request could take
an unbounded amount of time. Thus, the softdep_request_cleanup()
routine will only try for tickdelay seconds (default 2 seconds)
before giving up and returning a filesystem full error. Under typical
conditions, the softdep_request_cleanup() routine is able to free
up space in under fifty milliseconds.
