This driver supports GW3887 based chipsets and works on
x86/powerpc/sparc64. You need upgtfw kernel module before loading
upgt(4). Please see the manpage.

operating systems. Previously, gcc would inhibit the generation of
fsqrt, fsin, and several other floating point instructions, for the
benefit of the old in-kernel math emulator, which was removed over 5
years ago.
- don't run it if net.inet.ip.fw.verbose = 0 as it is pointless
- handle rules without logging limit correctly [1]
(those rules show up without logamount in "ipfw -a list")

1) Rename RANDOM_MAX to RANDOM_MAX_PLUS1 to not confuse with random()'s max
2) Use calloc() instead of zeroing fields explicitly
3) "too many lines" -> "too many delimiters" for err()

ID can't be 0xffff, so the test is still valid from a standards
perspective.

During the import of the 4.4BSD Lite sources, four files got added to
the repository called :tt, :tty, :var and :ww. They seem to contain some
kind of debug information. These files aren't used/installed anywhere.
Unfortunately the colons in the filenames prevents us from checking out
the source tree on file systems that don't support colons (such as FAT).
Just remove these unneeded files to keep SVN happy.

There is no reason the fdopen() routine needs Giant. It only sets
curthread->td_dupfd, based on the device unit number of the cdev.
I guess we won't get massive performance improvements here, but still, I
assume we eventually want to get rid of Giant.
that I have. Wait up to 1.1s for the card to become ready. Document
what the standards say, and use that to justify the behavior in the
code: PCI standard says that a card must respond to configuration
cycles within 2^25 cycles after reset goes high, which is
approximately 1s. Therefore, give cards a little break and wait for
up to 1.1s for VENDOR to become valid. Only look at the vendor part
of the ID, since only it can't be 0xffff (although in practice
vendor/device will always be != 0xfffffffff). Include detailed
pointers to standards so epople understand why we're doing what we're
doing and why it just might be OK. Make it clear in the timeout
message that it is just a warning, sinc we try to soldier on as best
we can anyway.
This should eliminate an error message that r181453 produced on
certain Atheros cards.
more mappings to the same physical page have different memory types, i.e.,
PAT settings. Consequently, if pmap_change_attr() is applied to a virtual
address range within the kernel map, then the corresponding ranges of the
direct map also need to be changed. Enhance pmap_change_attr() to handle
this case automatically.
Add a comment describing what pmap_change_attr() does.

and also holds things up, check every 20ms to see if we can read the
vendor of device 0.0. It will be 0xffffffff until the card is out of
reset. Always wait at least 20ms, for safety.
I think this is a better fix to the reset problem. However, I did it
as a separate commit in case something bad happens, people can roll
back to the commit before this one to see if that gives them reliable
behavior. I don't have FreeBSD up on enough machines to do exhaustive
testing on all known bridges...
some bridge + card combinations that take longer for reasons unknown.
Adjust the timeout to be 100ms on all !RICOH bridges, but leave RICOH
at 400ms. The 400ms is "lore" from other open source projects, and
I've never see my ricoh bridge chips take this long. Maybe it is the
same thing? Maybe a bit should be read instead of a hard-wired pause?
After this adjustment, a few cards that I'd insert and get only:
cbb0: card_power: 3V
cbb0: card_power: 0V
with full debugging enabled would actually try to attach.
