Subject: imx53 IPU support on 4.0.4


Hi folks,


I've rebased the IPUv3 patches from ptx folks onto 4.0.4,
working good for me. (now gst plays h264 @25fps on imx53)

https://github.com/metux/linux/commits/submit-4.0-imx53-ipuv3

(Haven't 4.1rc* yet, as it broke some other things for me.)

That's great.

Kamil mentioned that the scaler patches should be merged via the the
gpu subsystem:
http://www.spinics.net/lists/linux-media/msg88582.html

,so I guess Phillip will handle it.

What are the regressions you see?

While it's useful to broadcast your work, please have some consideration
for the forum(s) you're doing that to.

The way kernel development works is that patches are sent to mailing
lists for review. Kernel developers review the patches and provide
comments back. The comments are discussed and actioned, and a new
set of patches posted for further review. This cycle repeats.

When everyone is happy, the patches can be applied, or pulled from
a non-github git tree. (Kernel people generally don't like github.)

This is so that upstream kernel developers don't get too overloaded
with work that really should be done by downstream folk (imagine if
they had to rewrite every patch that came their way...)

Thanks.

This patchset is already in the queue, so nothing to be done here.
@Fabio, you simply have to be patient.

I am not sure why you are saying this as I was just explaining the
same to Enrico.
