[PATCH 0/7] Microship SAMA5D4 VPU support et al

[Emil Velikov]

Hi all,

This series adds support for the Microchip SAMA5D4 VPU, which it based
on the Hantro G1.

The hardware can support up-to 1280x720 for each of the MPEG2, VP8 and
H264 codecs. There is only a single decoder and no encoders on the SoC.

To minimise duplication, the series starts with a few small cleanups.


As you may have noticed, this is my first patches series to linux-media,
so any tips how to make this as smoother process are appreciated.


Looking forward to your feedback,
Emil

[PATCH 1/7] media: hantro: use G1_REG_INTERRUPT directly for the mpeg2

[Emil Velikov]

From: Emil Velikov <emil.velikov@collabora.com>

Use the register directly over the existing SWREG().

Ideally we'll port the driver away from the local registers, but for
now this is enough. For context - I was reading through the IRQ register
handling across the variants.

[PATCH 5/7] media: hantro: introduce hantro_g1.c for common API

[Emil Velikov]

From: Emil Velikov <emil.velikov@collabora.com>

The Hantro G1 IRQ and reset handling it pretty standard. I was this
close to duplicating it, yet again, before reconsidering and refactoring
it to a separate file.

[PATCH 5/7] media: hantro: introduce hantro_g1.c for common API

[Emil Velikov]

From: Emil Velikov <emil.velikov@collabora.com>

The Hantro G1 IRQ and reset handling it pretty standard. I was this
close to duplicating it, yet again, before reconsidering and refactoring
it to a separate file.

[PATCH 6/7] ARM: configs: at91: sama5: update with savedefconfig

[Emil Velikov]

From: Emil Velikov <emil.velikov@collabora.com>

While enabling an extra config, I've noticed that savedefconfig produced
a notable delta. Split out the no-op changes for clarity sake.

Usually device-tree changes go to their own patch.

The new compatible string "atmel,sama5d4-vdec" needs
an update to the DT bindings, see Documentation/devicetree/bindings/media/nxp,imx8mq-vpu.yaml
for an example.

DT bindings change should also go to a separate
patch, see Documentation/devicetree/bindings/submitting-patches.rst.

Better if config changes are a separate patch.

But also, the driver is in staging and we haven't enabled
in ARM64 defconfig. Let's leave that decision to the machine
maintainer to decide.

I haven't found information on how the series
was tested in the cover letter, could you add that to the next
iteration?

Please test the YUYV post-processed output and MPEG-2 decoding as well.

Also add the fluster score on this platform, and while here you could
give a pass at v4l2-compliance, which should pass without failures.
Note that you need to use v4l2-compliance HEAD from git.

Ah, the hantro_variant.init ops is not optional, but
if this VPU has no hw-specific init, then it should be.

In any case, we might get rid of it soon: Benjamin's work
will hopefully remove the i.MX8M need for ctrl_base.

And then the static clk_set_rate() in Rockchip variants could
be replaced with some dynamic rate using devfreq.

Makes sense. Will keep it separate patch for completeness sake, with
explicit note.
ARM/Microchip (AT91) SoC maintainers will be in CC list and will defer
the decision to them.

Nitpicking: I would use "microchip,sama5d4-vdec". We tend to use the 
microchip name for new DT bidings and compatibility strings.

I'm fine with having a "staging" component. Maybe add the hantro vdec as 
a module instead.

Should i use Microchip (instead of Atmel) only for the DT bindings or
throughout the series?

Yes, everywhere you can (Kconfig, explanation text, ...). Only keep 
Atmel/atmel where you cannot do differently or if it would require to 
modify code or move file just for this purpose.

The post-processed YUYV output can be requested like this in
GStreamer:

gst-launch-1.0 -v filesrc location=$something  ! parsebin ! decodebin ! video/x-raw,format=YUY2 ! ...

For MPEG-2 testing, I'm afraid there's no GStreamer yet for this,
but Jonas' ffmpeg should work https://github.com/Kwiboo/FFmpeg/commits/v4l2-request-hwaccel-4.3.
