zcrypt DD: Toleration for new IBM Z Crypto Hardware

Description:
Toleration support for new IBM Z crypto hardware

[Frank Heimes (fheimes)]

Since it's about toleration, I assume that this will affect focal (and with that impish) rather than jammy?
Because we have that ticket regarding exploitation in jammy: LP#1959547.

But changing ticket to Incomplete until details about kernel and/or required commits are shared.

Upstream with kernel 5.14-rc1, see

s390/AP: support new dynamic AP bus size limit

Patch went into impish (see IBM BZ#193340 - Canonical LP#1933805)

... IBM will do feature verification ...

Thanks for the details on the commit.
Yes, I can confirm that "s390/AP: support new dynamic AP bus size limit" is (as d5428ba5ba6b) already included in impish's 5.13 (with Ubuntu-5.13.0-15.15 and newer).

So it's now the question if it should also land in the 5.4 kernel of 20.04 or not (currently it's not in focal master-next).

Since it's about toleration, I assume that this will also affect focal (and with that impish, too)?

I've noticed that the focal case is already handled by LP#1954680 and LP#1954680 is Fix Released.
Hence I think we can close this ticket as Fix Released, too.
