771a93f3b7 imx8/lcd: reduce flicker
increasing the pixel clock to 80% of the edid clock value
reduces flicker and also seems to not trigger the shifting
issue.

from u-boot.

1d81f7eacb imx8/lcd: silly work around for display instability
running at the actual pixel clock causes the screen
to shift horizontally after a while.

using 60% seems to fix it - for now.

bb33663b40 git/get: keep sending what we have until we get an ack
Git9 was sloppy about telling git what commits we have.

We would list the commits at the tip of the branch, but not
walk down it, which means we would request too much data if
our local branches were ahead of the remote.

This patch changes that, sending the tips *and* the first
256 commits after them, so that git can produce a better
pack for us, with fewer redundant commits.

4eeefed7b0 cwfs: fix iounit negotiation
cwfs had an issue with iounit negotiation as a result
of the conversion to 9p2000 -- with the move to variable
size messages, the fixed message overhead decreased, but
the advertised message size was still adding the old
fixed overhead.

This meant that if the kernel negotiated the maximum io
size, cwfs would negotiate something larger than it
supported, and would hang up when an io of that size
was made.

In addition, the size of messages was stored in a short,
which means that negotiating an iounit larger than 16384
bytes would overflow the message count, and cause things
to fall over.

Finally, whle we're here, we clean up some duplicated
and unused constants.

13065e16b3 auth/box: don't bother switching to none
Changing the user to none doesn't do much for us
here. For kernel drivers that check the user of the
current proc we'll be none, but anything from devmnt
will still be accessed using creds from the original
attachment. Instead, running with none can be done
by chaining with auth/none:

auth/none auth/box ...

df92301d8f ip/ipconfig: refactor plan9 vendor parsing
Unless ip/dhcpd is started with the -6 option,
we only receive v4 addresses. If we do see the
v6 options we should prefer them but should
also make sure we grab the v4 addresses as a fallback.

None of the v6 options should overwrite valid
overrides given at the command line.

Add our custom types to logging.

d8d433894a kernel: cleanup unused fields from devpipe
We don't need to multiply session path by 2, the definition
for NETQID is:

Meaning we don't need to save room between session paths
for individual Qid paths. This doubles the amount of
pipe sessions we can have before a wrap.

5d37407e3c diff: avoid empty hunks when there are no changes
Currently, diff outputs a file header, even if there are
no changes to the file. This is wonky.

It means that the header chunks are ambiguous, since
not all header chunks are followed by '@@ hunk', and
'--- file', '+++ file' lines can be generated from
file content.

This changes the way that we decide to print the file
header, so we only print it when outputting the first
hunk on flushchanges.

Flushchanges is called once per regular file, at the
end of `diffreg`, so we output a hunk header once per
file.

07e1620911 patch: implement a new, simpler patch program to replace ape/patch
ape/patch is a giant, ugly ball of code from almost 25 years ago,
which has not and will likely never been updated or maintained.

the world has since settled on unified diffs, and we just need a
simple program that can parse and apply them.

01a6de812c git: performance enhancements
Inspired by some changes made in game of trees, I've
implemented a number of speedups in git9.

First, hashing the chunks during deltification with
murmurhash instead of sha1 speeds up the delta search
significantly.

The stretch function was micro-optimized a bit as well,
since that was taking a large portion of the time when
chunking.

Finally, the full path is not stored. We only care about
grouping files with the same name and path. We don't care
about the ordering. Therefore, only the hash of the path
xored with the hash of the diretory is kept, which saves
a bunch of mallocs and string munging.

This reduces the time spent repacking some test repos
significantly.

806896c19d tmparse: remove incorrect isalpha definition
Checking the range of c|0x60 incorrectly classifies many characters
as alphabetic (digits, control characters 0x01-0x20, and punctuation
characters '!'-':'). This prevents tmparse from parsing dates with
a timezone bounded by those characters (for example, "12:11:56 (PDT)").

Instead, just reuse the isalpha macro provided by ctype.h.

23f8872bc1 diff: retain original file names
When diffing non-regular files, like /dev/null,
pipes, and similar, diff will generate a temp
file to diff against. This is the right thing
to do, but the temp file leaks into the diff.

This patch retains the original file name all
the way through to diff output.

1da20fd5d8 imx8: add xhci driver for the soc
This is mostly a copy of port/usbxhci.c with PCIWADDR() replaced
by PADDR() and the pci specific code stripped out.

This could be refactored at a later time.

There is a gpio line for the main hub reset that needs to be
asserted and some power management functions that are currently
done by u-boot (using "usb start" command).

We will do these ourselfs once we have the infrastructure for
it in place.

fdbe335d3a aux/listen: remove special cases for depreciated datakit
The getserv function has remained mostly unchanged since
1ed. These checks are for handling string local ports
or lack thereof. This was used by datakit at the time,
where 'ports' were service strings. This made the default
datakit service 'login' when a connector did not give
a specific service. The checks for directory traversal also
seemed specifically to guard against a connector from providing
a malicious service string. With datakit gone all current protocols
use numerics as ports so these checks and defaults become uneeded.
