22 Patches From AMD Further Along Mesa's Workstation Performance

[smitty3268]

Is Mesa GPL/LGPL? If so, and AMD did borrow any code from it, they'd have to (L)GPL their whole windows stack, from that point upward.

It's MIT (mostly) and a few other permissive licenses in spots.

Is Mesa GPL/LGPL? If so, and AMD did borrow any code from it, they'd have to (L)GPL significant portions of their windows userspace driver.

Unless they only borrowed their own code (or got approval).

user1 AFAIK, OGLP is the closed source OGL driver that has been reworked to get better performance. This has replaced the old closed source driver in both Windows and Linux (i.e. amdgpu-pro's workstation GL). As far as I know, yes, the P in OLGP is short for PAL.

cb88 AFAIK only kernel space is shared, and maybe some low level interface bits.

I believe that is correct. It is also possible they reuse larger things like compilers where it makes sense if they are dual license (most of the MESA stuff is) but we have no way of knowing that.
