Phoronix: AMD Linux Graphics Driver Now Allows Display Support With Modern GPUs On LoongArch

Following the Linux 6.13 DRM feature pull this week that brought many new open-source kernel graphics driver features, it's now time to further stabilize that new feature code with fixes. Sent out today were a batch of fixes for the AMDGPU/AMDKFD kernel driver code targeting the early Linux 6.13 state. In addition to fixes though is also allowing the AMDGPU Display Core "DC" code to build properly on LoongArch hardware for allowing recent AMD Radeon GPUs to work on these Chinese systems...

What's AMD gonna do about the copyright mobsters at the HDMI forum telling them they can't have hdmi 2.1 support in the mesa drivers? Can they move the functionality to a binary blob? Not everyone has displays with displayport. There's also the proprietary non mesa drivers that amd also provides, they could always add hdmi 2.1 support to those assuming the HDMI forum won't throw another tantrum.

The LoongArch continues its things.
I wonder how many more years they'll need to get where Intel and AMD CPUs are, or even if they'll beat those 10 or 15 years from now.

phoronix ML, do you have a way to get your hands on those CPUs ?
A bench once a year to follow their progress would be nice.

Even if they were only close to Intel a year ago, that's pretty impressive.

If they could move it to binary blob then I'm pretty sure they would have already done it. AMDGPU-Pro works in user space and uses the same open source kernel driver as Mesa so they can't put it there either. Unlike NVIDIA GPUs AMD GPUs don't have RISC-V CPU so the functionality they can do in firmware is limited unless they will follow NVIDIA and put CPU on their cards that will be able to handle things like that. Another possibility is going Intel route. Intel GPUs internally output DP signal that is converted to HDMI with onboard adapter. With that Intel is able to provide HDMI 2.x output and still have open source driver.

For now if you don't want to change GPU all you can do is getting DP display.

The dedication of LoongArch hackers are very impressive.

The more sanction-proof Chinese CPUs are mostly divided between RISC-V with the more embedded-esque setup, and the UEFI-based, desktop-oriented LoongArch. It would be interesting to see how everything goes from here and who would take the upper hand...
