Add a way to disable Display Core per card
Describe the problem
We need to disable Display Core in order to get analog output support, and disabling Display Core makes HDMI output for audio unavailable.
Describe the new feature behavior
If the user has more than one card, maybe it'd be possible to only disable Display Core to the GPU that's serving images to the monitors, leaving other AMD cards the option to do HDMI audio.
Currently, in order to disable Display Core we use the following kernel parameter amdgpu.dc=0
, if there's a way to identify a card, perhaps something like amdgpu.disable_dc=identifier
could be added.
While, ideally, Display Core would gain support for analog output, I don't think anyone is working on it, so this could serve as a workaround for people who have two AMD cards.
