Mesa doesn't ship DRI1 drivers as of 8.0, which is about 18 months and three releases ago. The main reason to have wanted DRI1 AIGLX was to get a GLX compositor working, but DRI1's (lack of) memory management API meant that the cost of a GLX compositor was breaking direct GLX apps, which isn't a great tradeoff. Of the DRI1 drivers Mesa has dropped, I believe only mga stands to lose some functionality here, since it and only it has support for NV_texture_rectangle. Since that's required for every extant GLX compositor I know of, I conclude that anybody with a savage, say, would probably not notice AIGLX going away, since they wouldn't be running a GLX compositor in the first place. In the future we'd like to use GL in the server in a more natural way, as just another EGL client, including in the GLX implementation itself. Since there's no EGL implemented for DRI1 drivers, this would already doom AIGLX on DRI1 (short of entirely forking the GLX implementation, which I'm not enthusiastic about). v2: Remove DRI1 from AIGLX conditionals in configure.ac [anholt] Reviewed-by: Eric Anholt <eric@anholt.net> Signed-off-by: Adam Jackson <ajax@redhat.com>
