[Ubuntu 18.10 FEAT] new libocxl library

[bugproxy]

[Impact]

 * Userspace component required for hw-enablement of opencapi cards on POWER systems.

[Test Case]

 * Check that package is available
 * If one has opencapi cards, test they work with libocxl as built in bionic suite.

[Regression Potential]

 * This is a NEW leaf package, not installed by default, thus by definition cannot regress.
 * No change backport from cosmic.

[Other Info]

 * Original bug report

Add new package for libocxl, which is the user library which allows to interact with the new ocxl "generic" driver, used to interact with opencapi cards/accelerators.

This package is very important for POWER9, since this is the default userspace way to access OpenCAPI accelerators.

Not having this package on Ubuntu LTS will impact the OpenCAPI accelerators usage on Ubuntu on POWER9.

Packages cannot be downloaded from the Debian NEW queue. Did you want to provide the package directly to us for review or do you want to wait for the package to pass review in Debian?

Regarding introducing this new package in 18.04 (universe) here are the next steps to consider.

1. This package would first need to make it into 18.10, this bug would accomplish that.
2. Once it is introduced in 18.10, it needs to be tested, and tested to work with the 18.04 kernel.
3. Once it is tested and verified in 18.10 and with 18.04 kernel, *in a separate bug* request a backport of this package to 18.04.

It is my understanding that introducing this package in the 'universe' archive would be the path of least resistance. Introducing this in the 'main' archive, have it included in the iso, and auto pre-installed etc would be much harder.

Hi,
the packaging I pushed in Debian was accepted by ftpmasters into unstable and synced to 18.10/universe.

Hi Manoj,

This package is finally in 18.10. How can we proceed to get this package backported to 18.04 now?

[Łukasz Zemczak (sil2100)]

Hello bugproxy, or anyone else affected,

Accepted libocxl into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/libocxl/1.0.0-1~ubuntu18.04.0 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Do we have anyone that could actually check if the package works with opencapi cards?

The verification of the Stable Release Update for libocxl has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

I've tested the libocxl package on 18.04 and things look good.
