    the flurry-screensaver from xscreensaver seems to work much better now !

      Guess I will be filing a few of those pesky regression bugs...
      What verson of opengl does that require?

        just to let you devs know about this "problem"

        this way perhaps crashes might be prevented right from the start ...

        yellow == warning, but merges / installs

        red == warning & blocker, won't merge / install

        thanks for the merge (and the hard work contained in it)
        If you actually have something to report, and don't think that it's because of your CFLAGS, then file a bug.

          It's just that you need to include main/imports.h in src/mesa/shader/hash_table.c:

            Oh yes... Ubuntu 9.10 is moving to Mesa 7.6

            Packages for karmic should hit the mirrors soon! Hopefully they will patch the R6xx 3D stuff in the Ubuntu kernel because they have activated the R6xx driver in Mesa...

              Not sure, but the i965 driver supports opengl 2.1.

                Does this change affect Gallium3D?

                  I believe so, but not 100% sure. From what I can see, the interface between upper level mesa code and a Gallium3D driver includes a routine which converts Mesa IR to TGSI just before sending it to the driver.

                  http://cgit.freedesktop.org/mesa/mes...mesa_to_tgsi.c

                  The existence of that code (and the absence of a native TGSI code generator anywhere I could find) implies that existing Mesa code for parsing application shader programs and generating IR is still used, then the results are converted to TGSI at the last minute. The conversion appears to be very lightweight -- which fits with and supports Nicolai's decision to convert TGSI *back* to classic Mesa IR in the 3xx-5xx Gallium3D driver so that the existing shader compiler work could be re-used.

                  So "probably" yes.

                    It would be nice to see some benchmarks with the latest git code. Also, is Mesa 7.6 going to be released in time for the fall distribution updates?

                      You know, answering questions like that one sounds a bit like donating your money so other people get to buy a rope for your own hanging. :3
