It was pointed out to me that this is the convention for documenting upgrade
instructions, rather than just leaving the instructions in the commit message.
It's possible these commands won't be used again before we transition to git,
but then at least they'll give a path forward for whoever touches this next.

We use these to compile libefivar. The particular motivation for this update is
the inclusion of the RISC-V machine definitions that allow us to build the
library on the platform. This support could easily have been submitted as a
small local diff, but the timing of the release coincided with this work, and
it has been over 3 years since these sources were initially imported.
Note that this comes with a license change from regular BSD 2-clause to the
BSD+Patent license. This has been approved by core@ for this particular
project [1].
As with the original import, we retain only the subset of headers that we
actually need to build libefivar. I adapted imp@'s process slightly for this
update:
# Generate list of the headers needed to build
cp -r ../vendor/edk2/dist/MdePkg/Include sys/contrib/edk2
cd lib/libefivar
make
pushd `make -V .OBJDIR`
cat .depend*.o | grep sys/contrib | cut -d' ' -f 3 |
sort -u | sed -e 's=/full/path/sys/contrib/edk2/==' > /tmp/xxx
popd
# Merge the needed files
cd ../../sys/contrib/edk2
svn revert -R .
for i in `cat /tmp/xxx`; do
svn merge -c VendorRevision svn+ssh://repo.freebsd.org/base/vendor/edk2/dist/MdePkg/$i $i
done

The ice(4) driver is the driver for the Intel E8xx series Ethernet
controllers; currently with codenames Columbiaville and
Columbia Park.
These new controllers support 100G speeds, as well as introducing
more queues, better virtualization support, and more offload
capabilities. Future work will enable virtual functions (like
in ixl(4)) and the other functionality outlined above.
For full functionality, the kernel should be compiled with
"device ice_ddp" like in the amd64 NOTES file, and/or
ice_ddp_load="YES" should be added to /boot/loader.conf so that
the DDP package file included in this commit can be downloaded
to the adapter. Otherwise, the adapter will fall back to a single
queue mode with limited functionality.
A man page for this driver will be forthcoming.

Although I added the reset type field to ath_hal_reset() years ago,
I never finished adding it both throughout the HALs and in if_ath.c.
This will eventually deprecate the ath_hal force_full_reset option
because it can be requested at the driver layer.
So:
* Teach ar5416ChipReset() and ar9300_chip_reset() about the HAL type
* Use it in ar5416Reset() and ar9300_reset() when doing a full chip reset
* Extend ath_reset() to include the HAL_RESET_TYPE parameter added in the above functions
* Use HAL_RESET_NORMAL in most calls to ath_reset()
* .. but use HAL_RESET_BBPANIC for the BB panics, and HAL_RESET_FORCE_COLD during fatal, beacon miss and other hardware related hangs.
This should be a glorified no-op outside of actual hardware issues.
I've tested things with ath_hal force_full_reset set to 1 for years now,
so I know that feature and a full reset works (albeit much slower than
a warm reset!) and it does unwedge hardware.
The eventual aim is to use this for all the places where the driver
detects a potential hang as well as if long calibration - ie, noise floor
calibration - fails to complete. That's one of the big hardware related
things that causes station mode operation to hang without easy recovery.

Notable changes include:
* Improved decompress performance on amd64 and arm (5-10%
and 15-50%, respectively).
* '--patch-from' zstd(1) CLI option, which provides something like a very fast
version of bspatch(1) with slightly worse compression. See release notes.
In this update, I dropped the 3-year old -O0 workaround for an LLVM ARM bug;
the bug was fixed in LLVM SVN in 2017, but we didn't remove this workaround

Yes, people shouldn't use bitfields in C for structure parsing.
If someone ever wants a cleanup task then it'd be great to remove them
from this vendor code and other places in the ar9285/ar9287 HALs.
Alas, here we are.
AH_BYTE_ORDER wasn't defined and neither were the two values it could be.
So when compiling ath_ee_print_9300 it'd default to the big endian struct
layout and get a WHOLE lot of stuff wrong.
So:
* move AH_BYTE_ORDER into ath_hal/ah.h where it can be used by everyone.
* ensure that AH_BYTE_ORDER is actually defined before using it!
This should work on both big and little endian platforms.
Ok, yeah, the commit title is a bit misleading.
This has to do with CDD (cyclic delay diversity) - how this and later
wifi hardware transmits lower rates over more antennas. Eg, if you're
transmitting legacy 11abg rates on 2 or 3 antennas, you COULD just
send them all at the same time or you could delay each by tens/hundreds
of nanoseconds to try and get some better diversity characteristics.
However, this has a fun side effect - the antenna pattern is no longer
a bunch of interacting dipoles, but are a bunch of interacting dipoles
plus a bunch of changing phases. And it's frequency dependent - 50-200nS
is not exactly the same fraction of a wavelength across all of 2GHz or 5GHz!
Thus the power spectral density and maximum directional gain that you're
effectively getting is not .. well, as flat as it once was.
For more information, look up FCC/OET 13TR1003 in the FCC technical report
database. It has pretty graphics and everything.
Anyway, the problem lies thusly - the CDD code just subtracts another 3dB
or 5dB for the lower rates based on transmit antenna configuration.
However, it's not done based on operating configuration and it doesn't
take into account how far from any regulatory limits the hardware is at.
It also doesn't let us do things like transmit legacy rates and frames
on a single antenna without losing up to 5dB when we absolutely don't
need to in that case (there's no CDD used when one antenna is used!)
This shows up as the hardware behaving even worse for longer distance links
at 20MHz because, well, those are the exact rates losing a bunch more
transmit power.
* For lower power NICs (ie the majority of what is out there!) it's highly
unlikely we're going to hit anywhere near the PSD limits.
* It's doing it based on the existing limits from the CTL table (conformance
testing limits) - this isn't the regulatory max! It's what the NIC is
allowed to put out in each frequency and rate configuration! So things like
band edges, power amplifier behaviour and maximum current draw apply here.
Blindly subtracting 3 to 5dB from /this/ value is /very/ conservative..
* /and/ ath9k just plainly doesn't do any of this at all.
So, for now disable it and get the TX power back, thus matching what ath9k
in Linux is doing. If/once I get some more cycles I'll look at making it
a bit more adaptive and really only kick in if we're a few dB away from
hard regulatory limits.
Tested:
* AR9344 (2GHz + SoC, 2x2 configuration) - AP and STA modes
* QCA9580 (5GHz 2x2 and 3x3 configurations) - AP and STA modes
Now that armv4/v5 is gone, remove the bits that implemented atomic operations
by disabling interrupts.
Those were specific to FreeBSD and never reached upstream.
This is required to switch MIPS to compile with LLVM by default (D23204).

Remove an old workaround that is no longer necessary since rS343824.
There used to be a problem with FMan interrupts firing on multiple CPUS
at the same time.
This ended up being due to multicast interrupts being unsupported in the
Freescale PIC (so instead of using a selection algorithm, it would do some
unspecified action, such as interrupting multiple cpus at random.)

After the network epoch was added, we lost the ability to migrate the
ithread in the middle of dispatch, as being in the network epoch will pin
the current thread (for safety reasons.)
Luckily, we don't actually have to do this workaround in the first place,
as we can just bind it to the correct cpu when we preallocate it.
Pass dev through to XX_PreallocAndBindIntr() and actually bind it to the
cpu like it was supposed to in the first place, instad of leaving it
floating and moving it to the correct cpu the first time it fires.
This fixes panics while bringing up dtsec on my X5000.

Mock implementation of NETMAP routines is located in ena_netmap.c/.h
files. All code is protected under the DEV_NETMAP macro. Makefile was
updated with files and flag.
As ENA driver provide own implementations of (un)likely it must be
undefined before including NETMAP headers.
ena_netmap_attach function is called on the end of NIC attach. It fills
structure with NIC configuration and callbacks. Then provides it to
netmap_attach. Similarly netmap_detach is called during ena_detach.
Three callbacks are used.
nm_register is implemented by ena_netmap_reg. It is called when user
space application open or close NIC in NETMAP mode. Current action is
recognized based on onoff parameter: true means on and false off. As
NICs rings need to be reconfigured ena_down and ena_up are reused.
When user space application wants to receive new packets from NIC
nm_rxsync is called, and when there are new packets ready for Tx
nm_txsync is called.
