Backport packages for 16.04.3 HWE stack

I'll modify the hwe-pkg scripts so that packages will still use debhelper9, so dropping the requirement of backporting dh-autoreconf/debhelper.

I don't think we should change around the libxfont and libxfont1 source packages in SRU; this would e.g. make it more confusing to try to do security updates of libxfont in xenial if necessary. It also doesn't look to me like the version bump from libxfont 1.5.1 to libxfont1 1.5.2 is justified under SRU policy.

I would prefer to see:
 - libxfont source SRU, renaming libxfont-dev to libxfont1-dev
 - libxfont2 introduced as a new source package, which can be the libxfont from artful with a source rename.

For now, rejecting these two uploads from the queue pending discussion.

An upload of libxfont to xenial-proposed has been rejected from the upload queue for the following reason: "libxfont1 vs. libxfont2 source layout to be discussed".

I've uploaded fixed libxfont* to the queue.

About Vulkan package:

Vulkan loader (libvulkan) has moved to newer version and that is needed to make use of all the recently proposed vulkan extensions in the application.

The main application that doesn't work currently is with Vulkan CTS: https://github.com/KhronosGroup/VK-GL-CTS

Vulkan CTS passing is required for a device to be called as Vulkan compatible.

We support only LTS releases on our devices so need latest version on 16.04. Can you please upgrade the libvulkan.so version to 1.0.42 for Xenial?

This version is already available for latest ubuntu version (17.04).

Thanks.

vulkan 1.0.42 is already uploaded to the queue, just unapproved

Hi Timo,

>> vulkan 1.0.42 is already uploaded to the queue, just unapproved

It doesn't show in https://launchpad.net/ubuntu/xenial/+package/libvulkan1 so didn't know that it's already uploaded to the queue.

Please let me know how long the approval process takes and if I can be of any help to get it done.

Thanks,
~Sandeep

As part of a recent change in the Stable Release Update verification policy we would like to inform that for a bug to be considered verified for a given release a verification-done-$RELEASE tag needs to be added to the bug where $RELEASE is the name of the series the package that was tested (e.g. verification-done-xenial). Please note that the global 'verification-done' tag can no longer be used for this purpose.

Thank you!

For info, I've tested a build of chromium-browser (dev branch) with clang-4.0 from xenial-proposed, and that works well.

Hmm, I don't think xorg-server needs to be rebuilt against libxfont1-dev at this point.. if there's a need for SRU then this change could be done at the same time

xorg-server-hwe-16.04 (2:1.19.3-1ubuntu1~16.04.1) is working fine here (along with other related or required -proposed packages listed here.
Additionally with a modification to /etc/modprobe.d/nvidia-graphics-drivers.conf to enable KMS PRIME Synchronization is working on my hybrid (optimus) machines which has been sorely needed for many, many users.

Nack on this.
Please wait for virtualbox-guest-x11 being updated.

I uploaded virtualbox-lts-zesty and tested the hwe 16.04.3 in xenial VM,
installing virtualbox-guest-x11 and or virtualbox-guest-dkms/virtualbox-guest-source works.
Even the embedded kernel module works, so we should be good here.

You can test it on ppa:costamagnagianfranco/locutusofborg-ppa

So what's the final status of the SRU? It was verified before but then got held off. Does it need another re-test?

This will need a coordinated transactional release, when we're ready, please don't promote it.
