On the 8GB variant of the raspberry pi 4,
the eeprom chip for the xhci controller is missing and
instead loaded from sdram (by the gpu firmware).
for this, the gpu firmware needs to be notified of
the xhci controllers pci bus address (after reset)
that was assigned by our pci enumeration code.

parsing the unixheader in mdir fetch routine is the wrong place,
as no invalid character handling has been performed yet. also
the string is not neccesarily null terminated.
avoid duplication with plan9 mbox parsing and just do it in
parseheaders(), which already handles faking the unix headers
for pop3 and imap.

instruction cache maintenance is done on tlb miss;
when a page gets fauled in; with putmmu() checking
the page->txtflush cpu bitmap.
syssegflush() used to only call flushmmu() after
segflush() for the calling process, but when a segment
is shared with other processes, we have to flush the
other processes tlb as well.
this adds the missing procflushseg() call into segflush().
note that procflushseg() leaves the calling process alone,
so the flushmmu() call in syssegflush() is still required.
segmentioproc() does not need to call flushmmu() after
segflush() as it is never going to jump to the modified
page, hence the stale icache does not matter.

Using aux/trampoline to relay udp traffic needs a inactivity
timeout to be practical as there is no explicit connection
termination.

make sure we look for the end of the header within the
pointer range, and not accidentally read beyond hend.
also, messages are not null terminated, so this could
even go beyond the email data buffer.
get rid of mimeflag which was only used for some assert
checks.
take header length into account when comparing header
against ignored header strings.

The sample frequency is an artificial parameter used for
isochronous out transfers to better match the target
frequency (usually, a sound card).
when hz is set, devusb adjusts the endpoint's maxpkt to get
the requested frequency and a multiple of the samplesize per
packet.
however, when hz is not set, then we should calculate the
frequency from maxpkt, ntds and pollival, so all parameters
will be consistent with each other.

this breaks the sample from the seconds manpage, and overall
produces funky results. this needs alot more testing.
term% seconds '23 may 2011'
seconds: tmparse: invalid date 23 may 2011 near 'may 2011'
term% seconds '2019-01-01 00:00:00'

Redo date handling in libc almost entirely. This allows
handling dates and times from outside your timezones,
fixes timezone loading in multithreaded applications,
and allows parsing and formatting using custom format
strings.
As a test of the APIs, we replace the formatting code in
seconds(1), shrinking it massively.
The last commit missed a few removals, and made it
unnecessarily hard to do an update.

Go expects the error to be one of the three errors returned in
Bell Labs Plan 9. As listed in
https://github.com/golang/go/blob/f7ba82d68f90e20aa9e6aa973cb6f12321abec71/src/cmd/go/internal/lockedfile/lockedfile_plan9.go#L16:
// Opening an exclusive-use file returns an error.
// The expected error strings are:
//
// - "open/create -- file is locked" (cwfs, kfs)
// - "exclusive lock" (fossil)
// - "exclusive use file already open" (ramfs)
var lockedErrStrings = [...]string{
"file is locked",
"exclusive lock",
"exclusive use file already open",
}

This brings acme scrolling behaviour in line with that of 9front's rio
and sam, where the amount scrolled varies with a vertical position of
the pointer within the window, similar to how the scrollbar works.
At some point it would be good to implement a line-at-a-time scrolling
when the Shift key is pressed, as seen in rio. For this to happen the
acme keyboard input needs to be rewritten in terms of /dev/kbd instead
of relying on keyboard(2) -- that is, the /dev/cons interface.

Added a ver= field to the filter to distinguish the ip version.
By default, a filter is parsed as ipv6, and after parsing
proto, src and dst fields are converted to ipv4. When no
ver= field is specified, a ip version filter is implicitely
added and both protocols are parsed.
This change also gets rid of the fast compare types as the
filed might not be aligned correctly in the packet.
This also fixes the ifc= filter, as we have to check any
local address.
|

the ipmux pseudo protocol handles the extra ipv6 interface address
prefixed to the ip header as used by /net/ipmux packet filter.

Based off the following 3 commits:
4a3fb87264f8bc03fc62f00ef335056f30d18023

Reading /mnt/acme/log reports a log of window create,
put, focus, and delete events, as they happen. It blocks
until the next event is available.
Example log output:
8 new /Users/rsc/foo.go
8 put /Users/rsc/foo.go
8 del /Users/rsc/foo.go
This lets acme-aware programs react to file writes, for example
compiling code, running a test, or updating an import block.

We used to just return the first address of the incoming
interface regardless of if the address matches the source
ip type and scope.
This change tries to find the best interface address that
will match the source ip so it can be used as a source
address when replying to the packet.
