Cc: Vikash Garodia, dikshita, Stanimir Varbanov
Redesign core (vcodec) clock control to give the venus core more
freedom to control them in order to make possible to use core
selection feature on Venus IP v4.
Move all clock and pmdomain functions in separate file and abstract
power control with common operations per Venus IP version.

From: Aniket Masule <amasule@codeaurora.org>
Presently the core (vcodec pipelines) assignment is static. Here we
introduce dynamic load balancing across the cores depending on the
current session load. The load on earch core is calculated and core
with minimum load is assigned to given instance. This will be
applicable on Venus v4 with more than one vcodec cores.

Those two properties are not implemented for Venus v4 (sdm845),
thus don't set them to firmware.

This event indicate that the source color bit-depth is changed
during run-time. The client must get the new format and re-allocate
buffers for it. This can usually happens with video decoder (encoders)
when the bit-stream color bit-depth is changed from 8 to 10bits
or vice versa.

I think this is too specific for decoders. Something similar to the
CH_RESOLUTION description would be more appropriate:
- This event gets triggered when a color bit-depth change (but not a
resolution change!) is detected at an input. This can come from an
input connector or from a video decoder. Applications will have to query
the new pixel format and re-negotiate the queue.
For stateful decoders follow the guidelines in :ref:`decoder`.
Video capture devices will in most cases have to stop and restart
streaming (:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` followed by
:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`).
And update dev-decoder.rst where needed with this new event flag.
As to your question on irc: once I've acked this patch it can be merged
via a venus PR.

Hans

What you mean by "but not a resolution change" here? Resolution change
and bit-depth change cannot occur on the same time, or something else.
I would say that for Venus (and probably others) on initialization time
both could be changed on the same time, because we cannot predict the
resolution and bit-depth before parsing bitstream headers.

What I was trying to say is that a resolution change implies a possible bit-depth
change as well, whereas V4L2_EVENT_SRC_CH_COLOR_DEPTH is only set if there is
a bit-depth change but no resolution change.
V4L2_EVENT_SRC_CH_RESOLUTION requires that userspace does a full resync to the
new format, CH_COLOR_DEPTH implies that only the bit depth changed.
Which actually makes me wonder: is there a difference between the two change flags
w.r.t. userspace behavior? If there is, then that should be carefully documented,
if there isn't, then is this new flag really needed?

CH_COLOR_DEPTH implies format re-negotiation as well. In Venus case
8->10bit change will change the format of OPB buffers (now it is not
possible because of lack of v4l modifiers) and DPB buffers becomes
compressed raw buffers (to optimize bandwidth).

Looking into semantics of v4l events, CH_COLOR_DEPTH makes sense because
it describes what actually changed (similar to CH_RESOLUTION). I would
say that v4l2_event::type V4L2_EVENT_SOURCE_CHANGE implies format
re-negotiation and v4l2_event::src_change just informs userland what
exactly is changed.
I'll postpone this patch until we have clear vision what will be the
usage in user-space.

My main problem regarding semantics is what should be done if you disconnect
and reconnect an HDMI (for example) connector. You get a V4L2_EVENT_SOURCE_CHANGE
when the new signal is detected, but should it just set V4L2_EVENT_SRC_CH_RESOLUTION
(as it does today), or also V4L2_EVENT_SRC_CH_COLOR_DEPTH?
In my view V4L2_EVENT_SRC_CH_COLOR_DEPTH only makes sense if the resolution
stays the same, but only the color depth changes.
BTW, one thing that will be added here as well in the future is a
V4L2_EVENT_SRC_CH_COLORIMETRY for when the colorspace etc. information changes,
but nothing else. In that case there is no need to renegotiate the format etc.,
it's just the interpretation of the video data that changes.
An alternative approach is to define a V4L2_EVENT_SRC_CH_ALL bit mask, OR-ing
all the V4L2_EVENT_SRC_CH_* defines, and change all drivers that use
V4L2_EVENT_SRC_CH_RESOLUTION at the moment to use V4L2_EVENT_SRC_CH_ALL instead,
and only drivers that detect that only one of these changes took place will
use a specific V4L2_EVENT_SRC_CH_ flag. This will be primarily codec drivers,
I believe.
There aren't that many of those, so this shouldn't be too difficult to do.
Perhaps this is the cleanest approach to this problem...

Hans

I think disconnect -> connect should imply that everything is changed
i.e. source resolution, color depth and colorimetry. We cannot guess is
it the same HDMI source or not.

I can imagine a bitstream which changing resolution and color-depth at
the same time. And I guess h264|265 doesn't denied this to happen.

In case of colorimetry, maybe the buffer format will not change but
colorspace, quantization, ycbcr_encoding and transfer function will
change. And this imply that the userspace have to streamoff -> gfmt ->
do-some-action -> streamon ?
I have to figure out what is for example Android is doing when the
colorimentry is changed.
If someone knows, please shed some light on that subject.

Handle 10bit video streams in the decoder by using dithering, i.e
the decoder output buffers will be in 8bit format.
The runtime handling is implemented by sending v4l2 event to
userspace application, then the application should stop the
streaming on capture queue and initiate format negotiation, and
start streaming again.

In order to use dynamic video codec assignment add a new sdm845-v2
DT compatible and new venus_resource structure to cover the binding
where all pmdomains and clocks are under the venus_core control.
