Phoronix: AMD Adds New AMDGPU LLVM Targets For Older GPUs In Cleanup

Seeing new AMDGPU targets added to mainline LLVM for aging Radeon GFX7/GFX8 graphics hardware wasn't what I expected to see this weekend...

I didn't know what that was but this helps:

I take this a sign that making a profit is starting to pay off for AMD.

And starting to payoff for their loyal customers.

What work is left to do before being able to make AMDGPU the default kernel driver for GCN 1.1 ?

IMHO it was pretty obvious that this plumbing was coming , ... ;-)

Nice to see that they optimize their stack, even if it is fixing oversights which could have been caught before.

and gcn 1.0...

It would be nice if it supported VGA as a valid output on Bonaire, Kabini, Kaveri and Mullins

Someone needs to implement support for LVDS and DACs. It's not a high priority for us at the moment. If someone wants to take a stab at it, we'd be happy to review the patches. I think some of the older DAL2 code had some support for these encoders. You could use that or the non-DC code as reference. Old DAL2 code for reference:

LVDS has been done, VGA remains.

It doesn't help that the bug is marked 'inactive'. It certainly has not been solved.

I think mainly analog outputs and maybe some restart stuff.
