Phoronix: Mesa 11.0.4 Is Scattered With Fixes

For those not riding Mesa Git master for all of the latest open-source 3D driver functionality, Mesa 11.0.4 is now the latest stable release...

While most of us are concerned with catching up with the latest OpenGL version, I can't help but wonder... is there anybody dedicated to making sure Mesa (actual Mesa, not the drivers) is actually fast?

I think Jerome Glisse looked into this some years ago.

Yeah, here you go

at least a 75% of the total overhead comes from below the mesa state tracker.

Means Mesa does not matter that much, the interesting stuff happens in the drivers.

Mind you that mailing list thread was written 5 years ago. I'm not certain how much of those topics have been addressed. I'm sure bo overhead has been looked at many times since then.

Should I expect performance improvements from Mesa 11.0.4 for RadeonSI and AMD Bonnaire, or do I need Git master branch to be on the bleeding edge?
In other words, does 11.0.4 include all improvements that were in Git master before, or only those considered stable?
I guess the most performance improvements will come from switching to LLVM dev branch from LLVM 3.7.0 (as already mentioned, Mesa isn't everything), but I also care about stability.

I think Bonaire is GCN 1, which if true then I think you'll be fine sticking with whatever is stable. Although there are some newer games that won't run well or at all. Pretty much anything that requires GL4.2 and up will give you problems. There already are some fixes in git master to address some of those problems, but git is really a crap shoot, unless you already know specifically that it contains a fix you need then it may not be of any benefit to you.

EDIT: Really I'd say the best thing you can do is to make sure you have LLVM 3.7 installed, There are still some distro's releasing 3.6, which is wrong, just wrong.

EDIT: And of course if you are at all interested in contributing bug reports or fixes then by all means please use git and do whatever you can.

My first real commit

11.0.4 has just been released into Debian sid yesterday.
Have upgraded and working fine on Intel HD.
Nvidia driver is broken (did dist-upgrade), but should be fixed shortly I presume.
