           Summary: [r300g] Driver needs some kind of force_s3tc_enable
                    option
           Product: Mesa
           Version: git
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: rankincj@googlemail.com


Some games (such as World of Warcraft) need S3TC texture support, and so will
crash if the OpenGL S3TC extensions are not advertised. Currently, the only way
to make Gallium advertise the S3TC extensions is to load the IP-encumbered
libtxc_dxtn library.

WoW can run successfully using the r300c driver without the libtxc_dxtn,
provided the force_s3tc_enable option is used. (There are some issues with
corrupt textures, although some of these issues might be caused e.g. by r300c
not supporting texture cache regions. However, my point is that WoW doesn't
crash instantly with a null pointer exception if the S3TC extensions are
available.)

Agree. Some game are considering forcing S3TC this way (e.g. 0ad) and this
won't work with gallium drivers. I see also very few options with driconf with
gallium drivers, maybe other than force_s3tc_enable should be made available.

Moving to mesa core since this also affects softpipe.
