and subject line Re: Bug#882053: Additional investigations
has caused the Debian Bug report #882053,
regarding linux-image-4.13.0-0.bpo.1-arm64: feature request: enable contiguous
memory allocator (CMA) for arm64 (CONFIG_CMA=y)
to be marked as done.
This means that you claim that the problem has been dealt with.
If this is not the case it is now your responsibility to reopen the
Bug report if necessary, and/or fix the problem forthwith.

Package: src:linux
Version: 4.13.4-2~bpo9+1
Severity: wishlist
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
My goal is to generate a pure Debian arm64 image for the Raspberry
Pi 3.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I took the latest kernel from stretch-backports and discovered that
the vc4 graphics driver complains about missing CMA support.
* What was the outcome of this action?
The vc4 graphics driver will probably not work.
* What outcome did you expect instead?
It would be great if the arm64 (and probably also the armmp and
armmp-lpae) kernels would work out of the box on the Raspberry Pi.

In fact that has been released to experimental, so I'm closing this
with the released version.
