AMDGPU's DC Gets More Cleanups Ahead Of Linux 4.15

I hope in future AMD devs work more closely with the Linux guys

amd windows and hardware devs? well, feel free to hope

Is there any real use for these? I decode all on my HTPC and pass straight PCM to my receiver.

You cannot send Dolby Atmos and DTS:X as PCM. They have to be decoded by the AVR, because they are object-based (not channel-based) and only the AVR knows where in the room a sound object should be placed.

amdgpu.dc=1 sounds like it's just the ticket to RADV

i don't think radv depends on dc in any way, it depends on amdgpu, which is a separate issue

which unfortunately only works if you built it as a module.

If you built-in the driver, your bootloader (grub?) is your friend.

Looking forward to this! I hope in future AMD devs work more closely with the Linux guys, so that there isn't a "throw it over the fence" approach...

They do. Just have a look at amd-gfx mailing list.

I see, but what prevents the computer from knowing the locations?

For creative professionals producing AV works, most certainly. I'll take a fully compliant OpenCL 2.1 working stack and then these Audio quality formats in that order, but most certainly both of them. I'm creating animations and working with creating high end audio to add value to the creations.

I want the sound of an engine to reverberate 360 degrees.

Can't you get that reverberation in pure software?



Thank you for the explanations!

It was about listing the available options, not setting them.

In theory it could be possible. In my case I would need to pass 11.2 channels to my amp then, which Kodi simply does not support for example.

Furthermore I am not aware of any piece of Linux software which can actually decode Dolby Atmos at all. This is why you need to pass the Atmos stream to an AVR over HDMI.

Got it, thank you!
