In contrast, I would appreciate a better OpenCL support for the TeraScale 2 based Radeon HD 6000 series (like the TURKS hardware). Maybe we will see on that "front" during the next months some progress. But also here it should be noted that the OpenCL performance will not be as great because of some further shortcomings of the TeraScale architecture. It looks that consistently solid OpenCL results were not possible before the later GCN architecture which was also developed with a "computing perspective" in mind.

Nvidia actively supports even the GeForce FX series from 20 years ago. Unlike Mesa devs that can't copy and paste 5 lines of free public code to have OGL4 support on Terascale. Go figure...
Quadro FX Series were supported up to 2019 on Lin (340) and up to 2016 on Win7/10 (R340).
Yeah, actively supports, spiritually.

I'm not sure about the status of the FP64 emulation code but if it's not there yet over-riding with environment variables works fine AFAIK since FP64 isn't actually used.Test signature

My current setup is based on Kepler and first generation Maxwell all running Nouveau. Technically I could install the "evil drivers" to get Vulkan and CUDA/OpenCL on the Maaxwell, but the Kepler one is a mobile device and its last supported "evil driver" keeps glitching my laptop with unreliable suspension and Optimus support.

Aren't the Terascale parts already at GL 4.5 ?

Whatever, there is finally an experimental FP64 emulation available in Mesa 21.1. So I hope that it will be in near feature officially introduced. Alternatively, when I am on 21.1, I can set "R600_DEBUG=nir" and Firefox will be hopefully happy.

What I'd like to see even more than GPU compute capabilites, is automatic reclocking for the 9400M. The 340 series nvidia proprietary driver will get phased out soon and already has numerous issues. Does anyone know what's missing to implement this, where it would plug into the Kernel (dvfs/devfreq?) and maybe have some literature suggestions on how to write such an algorithm?

Originally posted by lorn10 View PostExactly, FP64 emulation is missing. That's the reason why my TURKS Radeon is still on GL 3.3. If I enforce higher GL in "/etc/environment" I will get GL 4.5 and GLSL 430. So i set both to same level, GL 4.3 and GLSL 430. Unfortunately Firefox thinks now that i am cheating and tells me "BLOCKLIST_FEATURE_FAILURE_SOFTWARE_GL".
If you would like to forcibly enable a graphics feature that is blocked on your system, follow these instructions. Warning: do this at your own risk. There usually are good reasons why features are blocked.
To force-enable WebGL, go to about:config and set webgl.force-enabled=true.Test signature
