Usually we have some OpenGL extensions :
proving that S3TC is enabled but since I have updated MESA, yesterday, they don't show there anymore. Initially I was thinking that it was a bug somewhere or voluntary disabled so I searched on my side, recompiled Mesa and the external libs... Still, theses extensions don't show but : I tested with a game who require S3TC and it still work..
So mesa support S3TC but hide the extension?
Or Mesa just don't show them anymore because enabled by default everywhere? (if they don't need to be displayed in the extension list like if they display them just to show that it's enabled and available.)
I did not find anything useful on the mesa git log.
German technology website Heise reports S3TC is no longer owned by S3, but was buyed long time ago from ATI and is therefore now owned by AMD.
Maybe we should ask the AMD opensource devision if they can ask their lawyers to make this patent available to MESA for free.
Indeed. News articles seem to suggest that AMD tried to intervene in HTC vs. Apple in December. HTC sued Apple for patent violations, bought the VIA tech, and added a bunch of patents to the war chest. Amd intervened (saying we own the patents), but the ITC threw the case out before any new info came about.
So I'm confused... Does AMD own the S3TC patent, or not?
If AMD really do own the patents, perhaps they would be willing to license them for use in Mesa, Gallium3D and the other open linux graphics projects and end this whole mess with S3TC then becoming fully supported everywhere it needs to be.
