Phoronix: R600/Radeon TGSI Shader Cache Gets Closer To Merging

Eventually the native machine code is going to be cached, right?
What's currently preventing that from happening?

For radeonsi yes. I will send the patch for that once the tgsi cache is upstream.

In order for this to work we need to build mesa with --enable-shader-cache ?

From which mesa release this improvement will run?

What about R600?

tarceri will shader cache help with stutters in dota2? Now on radeonsi i have heavy stutters when first loading into the game and sometimes when some skills used first time, etc. Do those stutters mean shaders are compiling/loading?

R600 should be HD2XXX & HD3XXX series, right?

R600 should be HD2XXX & HD3XXX series, right?

and HD4XXX, HD 5XXX, HD6XXX and some low-number HD7XXX. Everything that isn't a Graphics Core Next chip, essentially.
