Phoronix: A Lot Of The OpenGL Shader Cache Code Has Landed In Mesa

Timothy Arceri, who is now working for Valve (on the open-source AMD driver stack after leaving Collabora), has landed significant portions of his work built upon others for providing an on-disk shader cache within Mesa...

Finally. So Mesa 17.1 we might have a working shader cache.

Does Microsoft Windows use a shader cache?

Will the cache be located in /tmp/ or ~/.cache/ ?

the nvidia driver does it independently and I remember having seen a directory mentioning shader cache. (plus it's an option in the driver)
dunno about AMD, but I'd assume they have one too, but I doubt this is done OS-side, rather driver-side.

Can confirm on my laptop, as I have a ~/.nv directory containing ComputeCache and GLCache subdirectories created when using the nvidia driver

i was referring to windows, but yeah their proprietary driver supports it on linux too

it should be useful on chrome/chromium browsers.

Why wouldn't it when most of the code base is shared between them?

Does anyone know if this will be wired up to the GL_ARB_get_program_binary extension so that we will (finally) get a supported binary format? Does any game actually use that extension?

I'm not a huge fan of full driver-side implementations of the shader cache anyway, but since Dx11 AFAIK doesn't even allow a client-side implementation, things just turned out that way and it certainly is better than nothing.

with opengl you can do it yourself.
