Phoronix: Mesa 18.1 Receives OpenGL 3.1 With ARB_compatibility For Gallium3D Drivers

Going back to last October, Marek of AMD's open-source driver team has been working on ARB_compatibility support for Mesa with a focus on RadeonSI/Gallium3D. Today that work was finally merged...

there are some non enterprise programs that will also benefit from this

ARB_compatibility is missing as an entry in https://mesamatrix.net/ Other extensions.

Very happy that this has made it into Mesa. Will be useful for modern id games running in WINE.

Don't they require a 4.x compatibility profile? If so I don't see how this helps.

Hopefully this is connected to the crashes I'm experiencing while overriding GL profile to 4.x, just a hope.

I think it's fairly obvious at this point that the plan is to extend the compat profile support further, and this is just the first step.

Several other programs like Minecraft and Chrome use the compat profile

It's not that obvious to me based on the email:

OpenGL 3.1 with ARB_compatibility is tiny since most of the work was done a long time ago.

This is not really a Compatibility profile because the first Compatibility profile starts at OpenGL 3.2, but it's fundamentally the same thing.

It's not that obvious to me based on the email:

I doubt getting OpenGL 3.1 with a compat profile instead of 3.0 really makes much of a difference for anything, which is really more of why I felt that this was just a starting point from the beginning.

However, there was another message from Marek where he asked someone not to disable an extension under the compat profile because he'd like every extension in Mesa working under it eventually, so I do think the plan is to make it work for everything including GL4.6.
