Re: [PATCH v4 0/4] Add Synopsys DesignWare HDMI RX Controller

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Shreeya,

another hint:

Changing the EDID like you described fixed the 4k60fps BGR3 input.

But still for NV16/NV24 (I can't output NV12 for some reason) there is the error which Nicolas described.

The output from v4l2-ctl for NV16/NV24 is:

Plane 0           :
       Bytes per Line : 3840
       Size Image     : 8294400

According to Nicolas there should be an additional plane/more memory reserved.

This leads to errors when trying to read the device using for example gstreamer:

 gst_memory_resize: assertion 'size + mem->offset + offset <= mem->maxsize' failed


This seems to always happen using the  NV16/NV24 formats regardless of resolution/fps.


Best regards,

Tim

Sorry for the delayed response, I've been trying to reproduce this on my side
and to also fix it.

It seems you are right, 4K@60 fps doesn't work with the latest version of HDMIRX.
We found out that it could be because of the current EDID which shows some failures.

Though I wasn't able to test the following on my side since my device doesn't support
4K, one of my colleague tried to replace the EDID and 4K@60 fps worked fine after that.

If you'd like to try it yourself then following is the command to get the new EDID

v4l2-ctl --show-edid type=hdmi-4k-600mhz

You will have to replace the EDID in the driver with the EDID you get the from the above
command in HEX format.

Thanks for reporting this, I will soon send v5 with this change included in it.


Thanks,
Shreeya Patel
