[PATCH v3 0/7] hantro: set of small cleanups and fixes

[Ezequiel Garcia]

Hi all,

Cleanups and fixes, third iteration.

The main idea here is to address two issues, and while
at it, clean the driver a bit.

The first issue can be found in Patch 1, when the Request
API is used, the CAPTURE buffer should be returned _before_
the OUTPUT buffer, to avoid waking up userspace prematurely.

I noticed this issue while working on the rkvdec driver,
but this time I've decided to tackle it at the core,
in v4l2_m2m_buf_done_and_job_finish().

The second issue is a simple compliance issue, which is solved
by refactoring the driver, dealing with internal set format
properly.

Note that patch 7 still needs reviews from device tree maintainers.

Changes v3:

* Rebased media master.

* Revert buffer sequence removal change.

Changes v2:

* Fix compile warning introduced by patch 6.

* I'm adding two additional patches this time.
  Patch 7 converts the binding to json-schema,
  and patch 8 puts linux-rockchip mailing list in MAINTAINERS. 

Thanks,
Ezequiel

[PATCH v3 2/7] hantro: Set buffers' zeroth plane payload in .buf_prepare

[Ezequiel Garcia]

Buffers' zeroth plane payload size is calculated at format
negotiation time, and so it can be set in .buf_prepare.

Keep in mind that, to make this change easier, hantro_buf_prepare
is refactored, using the cedrus driver as reference. This results
in cleaner code as byproduct.

[PATCH v3 3/7] hantro: Use v4l2_m2m_buf_done_and_job_finish

[Ezequiel Garcia]

Let the core sort out the nuances of returning buffers
to userspace, by using the v4l2_m2m_buf_done_and_job_finish
helper.

[PATCH v3 6/7] hantro: Refactor for V4L2 API spec compliancy

[Ezequiel Garcia]

Refactor how S_FMT and TRY_FMT are handled, and also make sure
internal initial format and format reset are done properly.

The latter is achieved by making sure the same hantro_{set,try}_fmt
helpers are called on all paths that set the format (which is
part of the driver state).

This commit removes the following v4l2-compliance warnings:

test VIDIOC_G_FMT: OK
	fail: v4l2-test-formats.cpp(711): Video Capture Multiplanar: TRY_FMT(G_FMT) != G_FMT
test VIDIOC_TRY_FMT: FAIL
	fail: v4l2-test-formats.cpp(1116): Video Capture Multiplanar: S_FMT(G_FMT) != G_FMT
test VIDIOC_S_FMT: FAIL

[PATCH v3 1/7] v4l2-mem2mem: return CAPTURE buffer first

[Ezequiel Garcia]

When the request API is used, typically an OUTPUT (src) buffer
will be part of a request. A userspace process will be typically
blocked, waiting on the request file descriptor.

Returning the OUTPUT (src) buffer will wake-up such processes,
who will immediately attempt to dequeue the CAPTURE buffer,
only to find it's still unavailable.

Therefore, change v4l2_m2m_buf_done_and_job_finish returning
the CAPTURE (dst) buffer first, to avoid signalling the request
file descriptor prematurely, i.e. before the CAPTURE buffer is done.

When the request API is not used, this change should have
no impact.

[PATCH v3 4/7] hantro: Remove unneeded hantro_dec_buf_finish

[Ezequiel Garcia]

Since now .buf_prepare takes care of setting the
buffer payload size, we can get rid of this,
at least for decoders.

Indeed, now the check passes. I'll get a v4 just for this patch.

-device-tree bindings for rockchip VPU codec
-
-Rockchip (Video Processing Unit) present in various Rockchip platforms,

-- interrupt-names: should be

-- clocks: phandle to VPU aclk, hclk clocks
-- clock-names: should be "aclk" and "hclk"
-- power-domains: phandle to power domain node
-- iommus: phandle to a iommu node

Hi Heiko,

This patch was applied by the media people Hans and Ezequil without note
and test I think.

Errors for example:

I did test it, but I guess something felt thru the cracks.
If you'd be kind enough to submit a patch, that would be lovely.

Thanks!

Hi,

Question for the media maintainers Hans & Co. :

What's nxp,imx8mq-vpu.yaml doing under rga?
Why is rockchip-vpu.yaml inserted under rga instead of vpu?
