If you're building mesa, you know what drivers you want.
NACK, the default should be build as much as possible.
We don't build OpenVG, OSMesa, i915g, GLESv1, GLESv2, and a number of
Gallium state trackers by default.
And while having reasonable defaults for components like EGL and GLES
makes sense, having default drivers doesn't. I think we can roughly
split people who build mesa into two groups:
- developers& users
- distro packagers
Developers and users are going to be building for a particular system
with a single graphics card, so almost always they're going to have to
disable either DRI or Gallium drivers. The current default doesn't
work for them.
As a developer (working in core Mesa a lot), I like to build all the
drivers all the time so that I don't accidentally break something
somewhere. I don't think I'm the only one who should be doing that.
What configure options would you suggest in that case?
--with-dri-drivers=i915,i965,radeon,r200,nouveau,swrast
--with-gallium-drivers=r300,r600,i915,svga,swrast
or it'd be easy to change configure to support --with-dri-drivers=all
--with-gallium-drivers=all
Right now this works with either --with-dri-drivers or
--with-dri-drivers=yes. Changing that to --with-dri-drivers=all
wouldn't be so bad.
Distro packagers are either going to build everything they can, or
offer knobs for users to select what they want to build. In the case
of the former, they're not going to depend on our configure script to
tell them what to build, because we already know it doesn't build
everything.
Neither group is served well by selecting a bunch of drivers when none
are requested.
I hope my reasoning is clear now.
The proper fix here is to merge --with-dri-drivers and
--with-gallium-drivers, and have it figure with gallium/dri
drivers to turn based on that list, so:
--with-awesome-new-option=dri-vmwgfx,dri-i965
Merging those options sounds good to me too.
The more I've thought about it, the more I like this. I'll see what I can do.
