Here are new cxl patches we would like to include on Zesty kernel. These patches bring fixes for the CXL device driver for CAPI and CAPI2.
They apply on top of https://bugzilla.linux.ibm.com/show_bug.cgi?id=153737

New CXL patch on top of the serie:

Thanks

I built a Zesty test kernel with the requested 7 patches. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1700606/

[Breno Leitão (breno-leitao)]

Canonical is asking us (IBM) to test the kernel in the PPA before proceeding with the patch inclusion.

HI Breno,

Sorry for the delay,

The package architecture (amd64) is not correct. I am not able to perform tests.

Thanks

Hi,

Thanks for the packages, but the architecture (amd64) is not correct. We need ppc64le or could you give us the source kernel ?

Thanks

Sorry for the delay. I built a ppc64le Zesty test kernel with the requested 7 patches. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1700606/

We need the source of this kernel because we have to check the content of the cxl driver and we have
also to patch this one due a limitation on the CAPI card plugged on the machine.

If I'm not mistaken, the package is empty

Canonical,
We are *not* pursuing this feature for 16.04.3 anymore. We can catch up on the next release (no backports required in that case). We can close this bug.
