[Mesa-dev] [PATCH 3/3] glx: Enable GLX_EXT_texture_from_pixmap in software

[nobled]

Now if a software DRI driver advertises it, we can use it
in direct-rendering contexts--without this, only the server
took advantage of it for indirect contexts.

This follows up on these commits:

Like I commented below, are there any other extensions that it makes
sense to port to software drivers? Would invalidate be generally
useful there?
