Subject: [RFC 1/5] media: hantro: Add support for i.MX8M Mini

The i.MX8M Mini has a similar implementation of the Hantro G1 and
G2 decoders, but the Mini uses the vpu-blk-ctrl for handling the
VPU resets through the power domain system. As such, there are
functions present in the 8MQ that are not applicable to the Mini
which requires the driver to have a different compatible flags.

From what I can tell, the implementation between 8MQ and 8MM for the
G2 is basically the same with the only be difference being the
power-domain controller handling the vpu-blk-ctrl stuff in the Mini.
It doesn't hang, so I don't think the power-domain is a problem, but
the G2 throws some splat when v4l2-compliance is invoked.

That indicates that you did not compile v4l2-compliance from the git repo.

Please do that, that way I know you are using the latest compliance test.

git clone git://linuxtv.org/v4l-utils.git
cd v4l-utils
./bootstrap.sh
./configure
make
sudo make install

Hmm:

if (unlikely(order >= MAX_ORDER)) {
WARN_ON_ONCE(!(gfp & __GFP_NOWARN));
return NULL;
}

video needs loads of memory, so if MAX_ORDER is too low it might hit this.

It's tied to kernel config option FORCE_MAX_ZONEORDER.

The hantro driver uses vb2_dma_contig_memops, so the memory has to be physically
contiguous. That does indeed typically require larger MAX_ORDER values.

Hans
