[PATCH v4 00/21] Add MPEG-2 decoding to Rockchip VPU

[PATCH v4 00/21] Add MPEG-2 decoding to Rockchip VPU

[Boris Brezillon]

This series introduces the decoding infrastructure that will be
used to add support for other codecs such as VP8, VP9 and H.264.

As explained in the cover letter for the v1 patchset,
the driver is now exposing two video device nodes.
The VPU encoder is exposed on /dev/video0, and the VPU decoder
is exposed on /dev/video1. Both devices are tied to the same
memory-to-memory queue, and same media device /dev/media0.

Therefore there are two media graphs:

┌────────────────────────────────┐
│ rockchip,rk3399-vpu-enc-source │
│          /dev/video0           │

│          /dev/video1           │
└────────────────────────────────┘

Of course, this work has been possible thanks to Jonas Karlman, who did
the initial MPEG-2 decoding work and also got mpv+ffmpeg working using
the Request API.

Regards,

Boris

v4:
 * Fix issues in the probe/remove path preventing the driver from being
   unloaded/reloaded (Jonas)
 * Rework the media controller registration code to simplify the
   error/remove path (Boris)
 * Split the MPEG2 patches (one adding the generic code and one patch
   per platform)

v3:
  * Share more code between the encoder/decoder logic (VB2/V4L2
    interface implementation)
  * Add a patch to support MPEG2 decoding on RK3288 (Jonas)
  * Several fixes/improvements all over the place (see changelog
    in each patch for more details)

v2:
  * Fixed some minor issues brought up by v4l2-compliance.
  * Fixed bytesused wrongly assigned 0 on the MPEG-2 decoder.
  * Addressed comments from Hans and Tomasz on the pixel format
    helpers.

Boris Brezillon (7):
  rockchip/vpu: Remove a useless test
  rockchip/vpu: Get vdev from the file arg in vidioc_querycap()
  rockchip/vpu: Initialize mdev->bus_info
  rockchip/vpu: Rename rockchip_vpu_common.h into rockchip_vpu_v4l2.h
  rockchip/vpu: Move encoder logic to a common place
  rockchip/vpu: Provide a helper to reset both src and dst formats
  rockchip/vpu: Prepare things to support decoders

Changes from v2:

* Reword bounce buffer comment, so it's specific about JPEG.
* Rename helpers, start/stop to init/exit.

[PATCH v4 06/21] rockchip/vpu: Do not request id 0 for our video device

[Boris Brezillon]

From: Jonas Karlman <jonas-uIzNG4q0ceqzQB+pC5nmwQ@public.gmane.org>

Pass -1 to video_register_device() to let the core assign the first
free id instead of trying to get id 0.
In practice it doesn't make a difference since video_register_device()
is not strict about id requests and will anyway pick the first free id
starting at the id passed in argument, and passing -1 has the same
effect as passing 0. But let's comply with the API doc and pass -1
here.

[Boris Brezillon]

From: Jonas Karlman <jonas-uIzNG4q0ceqzQB+pC5nmwQ@public.gmane.org>

Those calls are needed to restore a clean PM state when the probe fails
or when the driver is unloaded such that future ->probe() calls can
initialize runtime PM again.

[PATCH v4 11/21] rockchip/vpu: Open-code media controller register

[Boris Brezillon]

From: Ezequiel Garcia <ezequiel-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>

In preparation to support decoders, using a single memory-to-memory
device, we need to roll our own media controller entities registration.

To do that, we define a rockchip_vpu_func object that embeds the
video_device object plus all the elements that are needed to attach this
vdev to the media device.

[PATCH v4 12/21] rockchip/vpu: Support the Request API

[Boris Brezillon]

From: Ezequiel Garcia <ezequiel-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>

Introduce support for the Request API. Although the JPEG encoder
does not mandate using the Request API, it's perfectly possible to
use it, if the application wants to.

Changes from v2:
* Drop unrelated mdev.bus_info changes.
* Remove the get_ref and get_ctrl helpers as they are not used yet.

[PATCH v4 13/21] rockchip/vpu: Rename rockchip_vpu_common.h into rockchip_vpu_v4l2.h

[Boris Brezillon]

We're about to add prototypes for the vb2/v4l2 helpers shared by the
encoder/decoder logic in this file, so let's pick a name that reflects
that (rockchip_vpu_common.h was a bit to generic).

[PATCH v4 14/21] rockchip/vpu: Move encoder logic to a common place

[Boris Brezillon]

The V4L2/VB2 implementation for the encoder and decoder logic are very
similar, so let's rename rockchip_vpu_enc.c file into
rockchip_vpu_v4l2.c and remove the _enc_ part in objects/functions
exposed in rockchip_vpu_v4l2.h. We also rename the enc_queue_init()
function (in rockchip_vpu_drv.c) queue_init() since it will be used
to initialize both type of queues.

The implementation itself will be patched to support the decoding case
when decoder support is added.

[PATCH v4 15/21] rockchip/vpu: Provide a helper to reset both src and dst formats

[Boris Brezillon]

When initializing a context, the core wants to reset both src and dst
formats. Right now the order doesn't matter, but if we want to have a
valid default width/height on the non-coded/raw format side (src in
case of encoders, dst in case of decoders), we need to reset those
formats in the right order: first the coded-format side, then the other,
such that width and height on the raw format side can be taken from
the coded format.

Let's provide a helper that will reset both formats and make sure this
is done in the right order.

[PATCH v4 16/21] rockchip/vpu: Prepare things to support decoders

[Boris Brezillon]

The code in rockchip_vpu_v4l2 was hardcoded for encoder support.
Modify it more generic to support the decoder case so that we can
re-use the same vb2/v4l2 ops for both devices.

[PATCH v4 17/21] rockchip/vpu: Add decoder boilerplate

[Boris Brezillon]

From: Ezequiel Garcia <ezequiel-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>

This commit adds the needed boilerplate code to support the VPU
in decoding operation. Two v4l2 interfaces are exposed, one for
encoding and one for decoding, but a single m2m device is shared
by them, so jobs are properly serialized.

Signed-off-by: Ezequiel Garcia <ezequiel-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>
Signed-off-by: Boris Brezillon <boris.brezillon-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>
--
Changes from v3:
* Update things according to changes done in the patch introducing
  custom media controller support (Boris)
* Move the rk3399 vdpu irq definition in the commit introducing
  MPGEG2 support on rk3399
* Fix media controller deregistration code (Jonas)

Changes from v2:
* Use the common vb2/v4l2 implementation
* Use strscpy instead of strlcpy.
* Abstract vidioc v4l2 api implementations into generic code, creating
  helpers that can be used by the encoder and the decoder.
* Only prevent S_FMT on the coded format queue, if the peer queue has buffers allocated.
* Refactor the code, adding a buf_finish callback to rockchip_vpu_ctx.
  With this change, is_enc field is not needed.
* Separate OUTPUT and CAPTURE queue ops (vb2_ops), and create common helpers that
  can be used by both.
* Pass a no kernel mapping attribute on both ends of the decoder.

[Boris Brezillon]

From: Ezequiel Garcia <ezequiel-ZGY8ohtN/8qB+jHODAdFcQ@public.gmane.org>

Rework the way controls are registered by the driver,
so it can support non-standard controls, such as those
used by stateless codecs.

Grand Total for rockchip-vpu device /dev/media0: 97, Succeeded: 92, Failed: 5, Warnings: 0

"

2 of those failures are expected: 

* "fail: v4l2-test-formats.cpp(806): fmt_cap.g_colorspace() != col": is caused
  by the reset done by the driver on the non-coded end when the coded end of
  the pipeline is modified (which follows the behavior described in stateless
  decoder spec)

* "fail: v4l2-test-controls.cpp(673): try_ext_ctrls returned an error (22)":
  default values for mpeg2 ctrls are not suitable, so doing
  get_ext_ctrl()+try_ext_ctrl() does not work.

I'm looking into the other failures which were not present in v3 (yes, I
know, shame on me for not running v4l2-compliance before sending the series :-)).

So is this a driver FIXME, or an issue in the compliance test itself?

Hmm, this might require some changes to this test. Where does it fail in the
driver? Is that the std_validate() check in v4l2-ctrls.c?

If so, then I think it would be wise to add an initializer for V4L2_CTRL_TYPE_MPEG2_SLICE_PARAMS
to std_init() so that it creates a proper default.

I also noticed that support for these new compound types is missing in
the std_log() function in v4l2-ctrls.c. It should probably log the
type. Check with v4l2-ctl --log-status to see how it looks in the
kernel log. Obviously, this can be done in a separate patch since it's
independent of the rockchip driver.

Looks like the spec mandates the opposite, so it's a driver bug. I'll
fix that. The main issue I see is that the RK encoder code has this
comment:

        /*
         * Current raw format might have become invalid with newly
         * selected codec, so reset it to default just to be safe and
         * keep internal driver state sane. User is mandated to set
         * the raw format again after we return, so we don't need
         * anything smarter.
         */

Does that mean we have a different behavior between encoders and
decoders?

Don't remember where it complained exactly, but it was in some generic
function, yes.

Okay.

Will look at it too.

Sure.

Yes. This is true for the stateful encoder as well: setting the capture
format can change the output format.

For a decoder it is the other way around: setting the output format
can change the capture format.

Note that we don't have a stateless encoder spec yet, but it makes sense
that it behaves in the same way in this respect as the stateful encoder.
