the access functions for pci config space in config mode #1
used to set bit 0 in the register offset if the access was
to a device on any bus different from 0.
it is completely unclear why this was done and i can't find
any documentation on this.
but for sure, this breaks all pci config spacess access to
pci devices behind a bridge on qemu. with -trace pci* it
was discovered that all config space register offsets on
devies behind pci brige where off by one.
on real hardware, setting bit 0 in the offset doesnt appear
to be an issue.
thanks mischief for reporting and providing a qemu demo
configuration to reproduce the problem.
On my 6235 card, if we calibrate the crystal
immediately after disabling wimax, the the
firmware gets unhappy. A short nap before
sending the command prevents the command from
timing out.
When moving messages between folders, mbappend,
deliver, and nedmail were trying to parse the
timestamp ouut of the message. They were doing
it incorrectly, trying to include the user name
as part of the date format.
Change to pass just the date to the date parser.
ori and echoline are reporting regression on some 6000 cards;
which sometimes time out on crystal calibration command;
which is expected by the driver. but the new code used
to force a device reset on any command timeout.
reverting to old behaviour until for now until we have
a chance investigating.
We used to assume a 1:1 pairing of processors to submit queues.
With recent machines, we now got more cpu cores than what some
nvme drives support so we need to distribute the queues across
these cpu's which requires locking on command submission.
There is a feature get/set command to probe the number of submit
and completion queues, but we decided to just handling
submission queue create command error gracefully as it is simpler
and has less chance of regression with existing setups.
Thanks to mischief for investigating and writing the code.
I have the problem that i need to delegate a subdomain
to another name server that is confused about its own zone
(and its own name) returning unusable ns records.
With this, one can make up a nameserver entry in ndb that
is authoritative and owned by us for that nameserver,
and then put it in the soa=delegated ns entry.
This promotes the ns record in the soa=delegated to
Authoritative, which avoids overriding the ns rr's from
the confused server for the delegated zone.
we used to only allocate ports from 6881 to 6890,
which limits the maximum of parallel torrents to 9.
this change make it go up to 9000, which gives us
at best 2120 ports, which is overkill but ports might
be randomly occupied by other connections.
the new date format introduced by the previous commit;
using numeric timezone offsets; needs one character more,
so increase the date format buffer to 31 characters.
the whole idea of a ucallocb() is bad, as even access to the
metadata header would be in uncached memory. also, it tuns out
that it was never used by anyone.
the 9000 series uses a new receive descriptor format
wich appears to reqire 4k aligned buffers. the old
format "halfworks" and just makes the firmware not
respond to any commands after the enable paging command.
the smartfifo command appears to causes problems.
but apparently not issuing it at all seems to work
fine on both the 8265 and 9260. so removing the code
for now.
issuing the bindingquota command before associated
makes association impossible. but enabling afterwards
works fine. (tested in 8265 and 9260).
the prph access functions now mask the address with
0xfffff. it is unclear why linux and openbsd drivers
specify addresses beyond that in ther register constants.
the timeevent change is interesting. the timeevent
needs to be restarted when it has stoped to make sure
probing/association packets are sent during the evnet.
Complete the conversion of upas to remove ctime,
use the new date library, and print time zones
in +hhmm format, instead of NNN format.
This may affect code that expects specific names
for timezones. Fix that code.
Recently the script which generates tab.h and the code including it got
incompatibly changed. People reported problems involving syntax errors
when trying to rebuild the system following a sysupdate.
The problem was with the script being embedded within a mkfile rule,
meaning that mk didn't notice it changing and therefore didn't rebuild
the target file. For people who were rebuilding the system this meant
that the old tab.h got included, causing syntax errors.
This patch moves the codegen script into a file and tells mk about this
new dependency, so that tab.h will get rebuilt for everyone. I also
took an opportunity to rewrite the script, hopefuly making it easier to
follow.
RFC959 says:
"The ALLO command should be treated as a NOOP (no
operation) by those servers which do not require
that the maximum size of the file be declared
beforehand..."
Ignoring '?' when formatting date strings allows
the format strings to be reused for parsing. This
is convenient, since we don't need to duplicate
the format strings.
Import the following improvements and bugfixes from plan9port:
4650064a acme: scale window bodies on resize, not including tag space
d28913a9 acme: save/restore multiline tags in Dump/Load
d2df5d6c acme: fix crash in X |cat with multiple windows
3d6e5cb5 acme: preserve window position and selection during Get
The format produced by `diff -u` is inferior to that
produced by `diff -c`, but it's what ape/patch and
unix patch expect, so it's useful to generate it.
This patch adds `diff -u`.
Following is a list of functional changes:
* The -o flag outputs the entire buffer to the length returned
by the syscall, or, in case of fd2path(2) and errstr(2), to '\0'.
* The -x flag is removed; the above makes it possible to pipe
into xd(1) to get the same result.
* The -s flag uses dirfmt(2) to format the stat message, instead
of trying to imitate ls(1).
* Stderr reports are normalized and made easier to parse.
The code also suffered a number of stylistic changes.
Right now, upasfs exposes header lines as is, without stripping
out new lines. It also documents that it provides one header per
line in the info file.
As a result, when we get a mail with headers that span lines,
our tools get confused.
These split lines are not semantically meaningful. From RFC5322:
2.2.3. Long Header Fields
Each header field is logically a single line of characters comprising
the field name, the colon, and the field body. For convenience
however, and to deal with the 998/78 character limitations per line,
the field body portion of a header field can be split into a
multiple-line representation; this is called "folding". The general
rule is that wherever this specification allows for folding white
space (not simply WSP characters), a CRLF may be inserted before any
WSP.
As a result, to simplify processing, we should just strip out the
line separators when exposing the headers from upasfs.
