[PATCH v5 00/27] Venus updates

[Stanimir Varbanov]

Hi,

Changes since v4:
 * 02/27 re-write intbufs_alloc as suggested by Alex, and
   moved new structures in 03/27 where they are used
 * 11/27 exit early if error occur in vdec_runtime_suspend
   venc_runtime_suspend and avoid ORing ret variable
 * 12/27 fixed typo in patch description
 * added a const when declare ptype variable

Previous v4 can be found at https://lkml.org/lkml/2018/6/27/404

regards,
Stan

[PATCH v5 09/27] venus: hfi_venus: move set of default properties to core init

[Stanimir Varbanov]

This moves setting of default properties (firmware debug, idle
indicator and low power mode) from session init to core init.
All of those properties are need to be enabled/disabled early
so that they could be used before the clients are even initialized.

The other reason is to set idle indicator property early before
we enter into venus_suspend function where we need to check for
ARM9 WFI.

[PATCH v5 12/27] venus: hfi_parser: add common capability parser

[Stanimir Varbanov]

This adds common capability parser for all supported Venus
versions. Having it will help to enumerate better the supported
raw formats and codecs and also the capabilities for every
codec like max/min width/height, framerate, bitrate and so on.

Re: [PATCH v5 12/27] venus: hfi_parser: add common capability parser

Hi Stanimir,

While preparing a pull request I ran smatch and I found some issues with
hfi_parser.h:

When compiling vdec.c and venc.c with smatch I get a whole bunch of:

drivers/media/platform/qcom/venus/hfi_parser.h:17:14: error: not an lvalue
drivers/media/platform/qcom/venus/hfi_parser.h:21:16: error: not an lvalue
drivers/media/platform/qcom/venus/hfi_parser.h:17:14: error: not an lvalue
drivers/media/platform/qcom/venus/hfi_parser.h:21:16: error: not an lvalue

To be honest I don't quite understand what is happening here.

What I DO see is that get_cap can return ERR_PTR, but the CAP_MIN/MAX/STEP macros
do not test for that. It doesn't feel right, I think it might be better if you
move get_cap into the source and provide little cap_min/max/step inlines that
properly test the return code of get_cap and return 0 or something on error.

This is the command line I use to test with smatch:

make W=1 C=1 CHECK="smatch -p=kernel" drivers/media/platform/qcom/venus/

I use smatch from here:

https://git.linuxtv.org/mchehab/smatch.git/

Otherwise everything looked good for this series, but I think this needs to
be fixed.

Regards,

	Hans

thanks for catching!

Do you want a new revisited version of this patch only? Or one patch on
top of the series?

[PATCH v6 12/27] venus: hfi_parser: add common capability parser

[Stanimir Varbanov]

This adds common capability parser for all supported Venus
versions. Having it will help to enumerate better the supported
raw formats and codecs and also the capabilities for every
codec like max/min width/height, framerate, bitrate and so on.

[PATCH v5 25/27] venus: implementing multi-stream support

[Stanimir Varbanov]

This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.

Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.

Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).

The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.
