I've have just pushed these to pretest as discussed last week:

$ git log --oneline bb2240e..2e35f88
2e35f88 make-flight: reorganize scheduling related test jobs
25ee621 Switch ARM testing back to linux-arm-xen branch.
339ad81 Debian: create boot.scr.nat when installing Xen on u-boot.
fcf00b2 TestSupport: replace power_cycle_timeout with power_cycle_sleep
70b19e1 Debian: Create boot.scr with a suffix and copy to boot.scr
e449fed ts-kernel-build: Adjust kernel .config to work on the arndale boards.
ee5e442 Osstest/Debian: Add 0x prefix to $filesize
0e24cb2 Osstest/Debian: Add clk_ignore_unused to default command line
653d0af Osstest/Debian: Remove hardcoded addresses from boot.scr
2d08c4c Osstest/Debian: support adding a rootdelay property to bootargs
64c57cb Osstest/Debian.pm: Refactor common kernel cmdline setup.
45e3b3c Osstest/Debian: Refactor setting of dom0 kernel command line.
070db63 Osstest/Debian: Support for loading an FDT from u-boot script
781c575 Osstest/Debian: Install dtbs into target filesystem in /boot/dtbs
2d92112 Osstest/PDU: Add eth008.pm method to control the ARM rack PDU
056840c make-flight: Run a basic test on each arm platform

That is: This series, the one extra patch to use linux-arm-xen for
kernels and Dario's scheduler rejigging.

I also ran:
OSSTEST_CONFIG=production-config ./mg-hosts setflags marilith-n\* -- 
platform-midway

So that 056840c does something.

Ian.

Hrm, how unfortunate. We expect that patch to land in ckt5 I suppose?

I think we can either wait for ckt5 or you could apply it to your
branch, which means future versions would need merging not
fast-forwarding. Not horrendous I suppose.

Both the cubietruck and the arndale are (for different reasons) not

I'm not sure if another LTS kernel is due from upstream soon or not, if

[Xen-devel] [PATCH OSSTEST v5 00/13] support for ARM32 arndale and cubietruck platforms

2015-01-22 Thread Ian Campbell 
I'm preparing a bunch of each of these boards to be racked for inclusion
in osstest. This series adds the necessary osstest support:

  * Support for platforms which require us to supply a Device Tree
  * Removing various hardcoded midway assumptions
  * Some new features needed to workaround h/w quirks (of arndale in
particular)
  * Support for the power relay switch board which these are
attached to
  * Some new convenience features

The series is completely acked now, reposting just because some of the
acks were given preemptively to give a chance for objections etc.

I've managed to make a habit of forgetting to mention one important
point (including hitting send on this bit in reply to v4!)

Both the cubietruck and the arndale are (for different reasons) not
supported by the 3.14 kernel which we currently use as a baseline for
osstest testing.

I'm not sure if another LTS kernel is due from upstream soon or not, if
not then I think we will need to resurrect the linux-arm-xen branch and
use it for all arm platforms (including midway, since I don't think we
want to take on the complexity of differing per platform).

So far I've been testing using v3.16.7, which is the last 3.16 longterm
release, however canonical are carrying it on at
http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.16.y
(up to 3.16.7-ckt4 at the moment). This is the same base as Debian will
be shipping in Jessie. So that is one option.

Stefano, do you have another preference?

WRT deploying we need to figure out the sequence in which we push these
patches, reenable the linux-arm-xen branch and commissioning the new
boards.

Ian.

Subject: [PATCH] Switch ARM testing back to linux-arm-xen branch.

The cubietruck and arndale boards need a newer kernel than our current
baseline of 3.14. Therefore switch all ARM testing to the
linux-arm-kernel branch which has been moved up to test v3.16.

This effectively reverts commit 38b2fe2020883 Switch armhf to use
common default Linux.
