Can some kind soul point me a good reading about Mesa and LLVM? I have one box with nVidia blob, why is Mesa still pulled in, do I need it? Mesa pulls in LLVM, I think I do not need it either?

Buffoon,

You do not need mesa with the nvidia binary blob.

Try
Code:
equery depends mesa
to see what needs mesa.

On my system only
Code:
www-client/firefox-39.0 (>=media-libs/mesa-10.2)
hard depends on mesa.
Everything else can avoid it with the careful setting of USE flags.

Thanks! That's what I thought.

Now, I have another box running nouveau, I guess I need Mesa there but no LLVM? Do I need gallium with nouveau?

Thanks again, I still hope there might be a good article for dummies somewhere to explain all this Mesa, Gallium and LLVM mess in simple words. Where is Gusar now?

Buffoon,

Did you finally try Mesa with LLVM for your nouveau-based system? I'm curious to know if software rendering (llvmpipe) really improves wrt to the standard "softpipe" method.

WOW. I just did it, and (can hardly believe it) got 450% performance improvement!! Indeed, glxgears (gallium renderer) gives:

  • softpipe: 54 FPS
  • llvmpipe: 244 FPS

Also, on my modest system (NVIDIA C51 [GeForce Go 6150], AMD Turion 64 X2), SeaMonkey can now play some rich WebGL-based content which was previously... unaffordable.
