Phoronix: AMD Wires In A Few More Extensions For Their Open-Source OpenGL Driver

It looks like open-source AMD driver developer Marek Olšák is finishing out the month by working on a few remaining extensions to benefit not only their RadeonSI driver but also the old R600g and other Mesa drivers...

[boxie]

there can't be that many extensions left that fglrx supports but radeon does not...

[Leopard]

Typos:

Marek addeds upport

already in most games/worklaods

Software fp64?

I'm pretty sure mesa supports more at this point. fglrx doesn't have anything for OGL 4.6 (not sure about 4.5) and nothing for Vulkan either.
On the other hand, I think fglrx has more/better OpenCL support, at least if you're using a GCN 1.1 or older GPU.

[Deavir]

Sounds like it is on some AMD checkbox of features that someone needs before they can think to drop the old driver. That or some old software uses it from a large corporation/government that they can't live without and no one will touch the code.

Current one on Windows have GL 4.6 exposed and something like 320 extensions

Or more than 400+ ever on all OSes

[dungeon]

In year 2002. there was 77 extensions

http://www.humus.name/index.php?page=News&ID=25

So, as of end of year 2015. that means how FGLRX added (minus these removed in the meantime ) on average more than one extension every month

Here you go from last FGLRX, about 281 extensions:

here we go, more than a month later I am finally getting around to doing this comparison... better late than never, right?

so, doing a straight up string comparison I get 40 missing extensions, but as you can see - some of these are just naming (shader image load store is in the fglrx as both GL_EXT_ and GL_ARB_). But for workstation compliance I am sure they would add in that alias Interesting list nonetheless
