make the find it does extremely expensive, so compute it only
once. Also make sure the 'traditional' module building method works at
the expense of a bit of duplicated code.
and start teaching subsystems about it.
The Atheros MIPS platforms don't guarantee any kind of FIFO consistency
with interrupts in hardware. So software needs to do a flush when it
receives an interrupt and before it calls the interrupt handler.
There are new ones for the QCA934x and QCA955x, so do a few things:
* Get rid of the individual ones (for ethernet and IP2);
* Create a mux and enum listing all the variations on DDR flushes;
* replace the uses of IP2 with the relevant one (which will typically
be "PCI" here);
* call the USB DDR flush before calling the real USB interrupt handlers;
* call the ethernet one upon receiving an interrupt that's for us,
rather than never calling it during operation.
Tested:
* QCA9558 (TP-Link archer c7 v2)
* AR9331 (Carambola 2)
TODO:
* PCI, USB, ethernet, etc need to do a double-check to see if the
interrupt was truely for them before doing the DDR. For now I
prefer "correct" over "fast".
This stops the panics that occur on MIPS platforms when doing say,
'sysctl dev.ath.0' whilst the MAC is asleep. The MIPS platform is
rather unforgiving in getting power-save register access wrong and you
will get all kinds of odd failures if you don't have things woken
up at the right times.
Tested:
* QCA9558 (TP-Link Archer C7 v2)
* AR9331 (Carambola 2)
.. with no VAPs configured and ath0 down (thus the MAC is definitely
asleep.)

Allow Makefiles to define generic metadata settings that apply to all test
programs defined by a Makefile. The generic TEST_METADATA variable extends
the per-test program settings already supported via TEST_METADATA.<program>.
This feature will be useful to easily apply some settings to all programs
in a directory. In particular, Kyua 0.12 will support parallel execution
of test programs and a bunch of them will need to be tagged as is_exclusive
to indicate that they cannot be run in parallel with anything else due to
their side-effects. It will be reasonable to set this setting on whole
directories.

Plain test programs are not preprocessed by the build system (as opposed to
ATF test cases, which automatically gain a shebang pointing at atf-sh), so
we must take care of providing the shebang ourselves.
I'm not sure why this was not causing problems with Kyua 0.11, but the
upcoming 0.12 release chokes on this particular issue.

cleanup routines can be executed at any point during the execution of the
body, including even before the body has done any real work. In those
cases, cleanup routines should be careful to not raise spurious errors so
as to not "override" the actual result of the test case.
This is just general good coding style but is not a problem in practice
for these specific tests. (The way I discovered the issue, though, was
due to a regression I introduced in Kyua itself while refactoring some
internals.)

This would only occur for the case where there was no explicit

return a cannonical name for the server.

change to GMAC easier on A20 SoCs.
On A10 only the EMAC controller is available (fast ethernet), but on A20
there is also GMAC a high (or better) performant controller (gigabit
ethernet).
On A20 the both controllers uses the same pins to talk to the ethernet PHY
(MII or RGMII) and they can be selected by the GPIO pin mux.
There is work in progress to bring in GMAC support.
When IPSEC is enabled on the kernel the forwarding path has an optimization to not enter the code paths
for checking security policies but first checks if there is any security policy active at all.
The patch introduces the same optimization but for traffic generated from the host itself.
This reduces the overhead by 50% on my tests for generated host traffic without and SP active.

The Allwinner SoC has an AHCI device on its internal main bus rather
than the PCI bus. This SoC is somewhat underdocumented, and its SATA
controller is no exception. The methods to support this chip were
harvested from the Linux Allwinner SDK, and then constants invented to
describe what's going on based on low-level constants contained in the
SATA standard and guess work.
This SoC requires a specific AHCI channel setup in order to start the
operations on the channel properly.
Clock setup and AHCI channel setup idea came from NetBSD.
Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by

The SoC, the flash, the ethernet ports and ethernet switch all work.
The USB works.
The 11ac PCIe NIC internally is at least seen by the PCIE RC, but
I haven't tried using it yet. There's no driver and I haven't
yet swapped it out for a non-11ac chip.
The on-chip 2GHz wifi works, but there are some data errors that
get thrown up in STA mode when scanning. I have a feeling I have
to finish the DDR flush code out and have it run correctly on the
shared interrupts; that'll take a bit of time to get right.
But if you're after an updated piece of hardware, the Archer C7 v2
is certainly there, and you can replace the 11ac NIC with a 3x3
Atheros PCIe device (eg AR9380, AR9390, AR9580, etc) and it'll
"just work".

The Tp-link Archer-C7v2 unit has a QCA9558 internally but hangs the

So I actually finally /do/ have a board to verify whether PCIe is working.

For now, add the geom_label_load entry to loader.conf, and

my BeagleBone Black to boot fine with a UFS label reference in
