| 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. |
