SubjectRe: [PATCH v5 00/16] Rockchip ISP1 Driver
From
Date
Hi Shunqian Zheng,

Thank you for this patch series. My apologies for the late reply, it arrived
in the middle of my Christmas vacation and completely forgot about it afterwards.

I finished my review. Besides small stuff I have basically two things that need
resolving: proof that the param/stats meta data has the same layout for 32 and
64 bit ARM compilers and the use of the deprecated g_mbus_config op. I'll discuss
the latter with Thomas tomorrow.

For v6 I would like to see the output of v4l2-compliance for this driver included
in the cover letter. If the regular v4l2-compliance (no arguments other than -d)
passes, then you can also try v4l2-compliance -s, and if that passes than try -f.
The last one cycles through all formats.

Always compile v4l2-compliance from the latest v4l-utils.git.

It's even more important than usual since I added tests for /dev/v4l-subdevX and
/dev/mediaX devices last weekend.

You'll need to apply these two patches first if you want to test such devices:

https://patchwork.linuxtv.org/patch/46817/
https://patchwork.linuxtv.org/patch/46822/

It's brand new code, so there may be bugs in the tests themselves.

BTW, next time if you don't hear from me for more than 2 weeks, then ping me.

Regards,

Hans
