this add functions for:
- remove buffers from src/dst queue by index
- remove exact buffer from src/dst queue
also extends m2m API to iterate over a list of src/dst buffers
in safely and non-safely manner.

* core.c has implemented the platform dirver methods, file
operations and v4l2 registration.
* helpers.c has implemented common helper functions for:
- buffer management
- vb2_ops and functions for format propagation,
- functions for allocating and freeing buffers for
internal usage. The buffer parameters describing internal
buffers depends on current format, resolution and codec.
- functions for calculation of current load of the
hardware. Depending on the count of instances and
resolutions it selects the best clock rate for the video
core.

Just a suggestion: this might work better if you split it in groups of

of what it is for. It's a solid block of fields right now and I think
it can be made a bit easier to read that way.

This logic can't be right: if type == CAPTURE and the plane_size
>= output_buf_size, then it will fall into the 'else' and check
the same plane_size against the input_buf_size, which is clearly
wrong for a CAPTURE buffer.

Since this is on the recovery path I'm not sure how to proceed on error
path. Delay the workqueue and try again later? Whatever, I can rework
this to print the errors instead of ignoring them.

Just curious: is NV12 the only uncompressed format supported by the hardware?
Or just the only one that is implemented here?

The downstream kernel[0], from Qualcomm have:
{
.name = "UBWC YCbCr Semiplanar 4:2:0",
.description = "UBWC Y/CbCr 4:2:0",
.fourcc = V4L2_PIX_FMT_NV12_UBWC,
.num_planes = 2,
.get_frame_size = get_frame_size_nv12_ubwc,
.type = CAPTURE_PORT,
},
{
.name = "UBWC YCbCr Semiplanar 4:2:0 10bit",
.description = "UBWC Y/CbCr 4:2:0 10bit",
.fourcc = V4L2_PIX_FMT_NV12_TP10_UBWC,
.num_planes = 2,
.get_frame_size = get_frame_size_nv12_ubwc_10bit,
.type = CAPTURE_PORT,
},
I have no idea what UBWC stands for. The performance in NV12 is more
then decent from my testing. Though, there is no 10bit variant.

Nicolas

yes, at least to my knowledge (except below UBWC).

UBWC is some kind of compressed format for NV12 [1]. This format is
applicable for the newer venus hardware revisions and I planed to add it
later on (when Adreno GPU driver starts handle it).

<snip> three reasons:
- _MPLAIN allows one plane only
- downstream qualcomm driver use _MPLAIN (the second plain is used for
extaradata, I ignored the extaradata support for now until v4l2 metadata
api is merged)
- I still believe that qualcomm firmware guys will add support the
second or even third plain at some point.

Correct. I can add sequence for the OUTPUT queue too, but I have no idea
how that sequence is used by userspace.

Neither GStreamer or Chromium seems to use it. What does that number
means for a m2m driver ? Does it really means something ?

It can be used to detect dropped frame (the sequence counter will skip in that
case).
Unlikely to happen for m2m devices, and most apps ignore it as well. But you
still need to fill it in, it's a V4L2 requirement.

You set V4L2_BUF_FLAG_TIMESTAMP_COPY, so you have to copy the timestamp from the output buffer
to the capture buffer, if that makes sense for this codec. If not, then you shouldn't use that
V4L2_BUF_FLAG and just generate new timestamps whenever a capture buffer is ready.
For sequence numbering just give the output queue its own sequence counter.

The timestamp_us is filled by firmware and it is the timestamp of the
output buffer which is used to produce the uncompressed capture buffer.
So I think V4L2_BUF_FLAG_TIMESTAMP_COPY is correctly used here.

OK will do.

Btw, GStreamer and Chromium only supports TIMESTAMP_COPY, and will most
likely leak frames if you craft timestamp.

Please add a comment in the code explaining the reason. Just before this format list would be
a good place for that.

This is the implementation of HFI. It is charged with the
responsibility to comunicate with the firmware through an
interface commands and messages.
- hfi.c has interface functions used by the core, decoder
and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.
- hfi_cmds has packetization operations which preparing
packets to be send from host to firmware.
- hfi_msgs takes care of messages sent from firmware to the
host.

Here is the implementation of Venus video accelerator low-level
functionality. It contanins code which setup the registers and
startup uthe processor, allocate and manipulates with the shared
memory used for sending commands and receiving messages.

Can this also depend on COMPILE_TEST? And if so, please make sure it compile on both
a 32 and 64 bit environment to shake out any compiler warnings.

I don't see this patch on linux-media. Can you post that one again?
Can you also post the v4l2-compliance test results? Make sure you compile
v4l2-compliance straight from the git repo to avoid testing with an old
version.
Thanks!
