R600/Radeon TGSI Shader Cache Gets Closer To Merging

[boffo]

i guess its compiler is faster

Might be, but the loading times..................... still loading................... still loading...................

Please, could you elaborate on this? When a game introduces a shader, r600 compiles it, and keeps in RAM (VRAM?) until the game exits. Or doesn't it? Do I misunderstand something?

when game introduces same shader again, r600 compiles it again

but that's glsl compiler, not r600. glsl is cached now

RadeonSI memory cache handles shader variants, caches parts that don't change.

Today I wanted to look at it — turns out, r600 have in-memory cache of shader variants since 2012 https://lists.freedesktop.org/archiv...ne/022689.html So no, @tarcery probably mean something different.
