133MHz is the minimum clock frequency in the GCC driver? Do you think
that will change?

Re: [PATCH 1/2] media: venus: Add support for MSM8939

[Konrad Dybcio]

Hi Stan,

I have found some issues with the submitted GCC driver, related to
venus, but I have to further look into them locally and work out some
stuff. One of the things is that freq table for venus clock should be
changed to the values found here [1] (currently it has 8916
frequencies). When I find all the causes I'll resubmit this and
include them in the cover letter, as I might've overlooked something
wrt venus driver itself when creating this patch from my WIP branch.
Also it seems like I tested this very patch incorrectly (getting
segfaults in ffmpeg with v4l2m2m now)... Anyways, I'll get back to you
when I make it work for sure. Sorry again for the inconvenience.

OK. Thanks for the details, I'm waiting for good news :). If you need
some help with Venus bringup ping me on IRC - my nickname is svarbanov
on #v4l channel.

Regarding to venus clocks, these two clocks exist in below gcc driver
but missing in msm8916:

gcc_venus0_core0_vcodec0_clk
gcc_venus0_core1_vcodec0_clk

but the Venus IP block should be the same as in msm8916. Can you point
me to the donwstream gcc driver or check from where they comes.

My bot found errors running 'make dt_binding_check' on your patch:

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.

Ah, mea culpa!

I completely forgot to mention that this depends on the MSM8939 GCC
driver that has been sent a few days ago, sorry.. [1]

Have you found any additional mistakes in this patch that I should
correct besides this one?

Re: [PATCH 0/2] Add support for venus on msm8939

[Stanimir Varbanov]

Hi Konrad,

Thanks for the patches!

Could you describe hear what is the status of the new added SoC. Is
Venus driver tested on this new platform or that will happen at some
later point in time.

Also, in both patches the description is missing, please add something.

Re: [PATCH 0/2] Add support for venus on msm8939

[Konrad Dybcio]

Hi Stan,

Unfortunately it seems like I made some mistakes, as I've pointed out
in the reply in [1/2] patch,
and therefore this submission can go to the bin and wait for a v2. But
answering your question
wrt to 8939:

The platform is currently shaping out good, as we can reuse a large
number of 8916 drivers.
At the moment we have 4 out of 8 cores working reliably with
out-of-tree patches (8939 doesn't support psci)
and the latter 8 cores aren't there only because of the core
interconnect not being handled yet
(well they can be enabled but performance goes waaaay down when one does so).
As for other features, I have adreno, iommu, i2c, sdhci and other
basic things like that working,
and Vincent Knecht (cc) with an Alcatel Idol 3 5.5 (same SoC) even
reportedly got USB and
Wi-Fi to work (though we have different hardware in both situations).
Currently Vincent and I have local support for the aforementioned
Alcatel, Asus Zenfone 2 Laser
1080p (Z00T) and partial support (as in no panel yet) for Sony Xperia
M4 Aqua with Linaro
folks preparing some drivers (like GCC) for an unknown-to-me 8939 board
(or perhaps a phone, too?). I already pushed Adreno 405 enablement to
mesa, too and it's
going to be there in the next release, so this platform will only get
better from now.

Konrad
