[Mesa-dev] Manipulate GALLIUM_HUD post-launch (interactively)

[Jimmy Berry]

I have found myself desiring the ability to manipulate the GALLIUM_HUD
variable while an application is running. At the most basic simply
being able to toggle the hud on and off would be great. Otherwise, one
has to relaunch an application and get back to the same state which
may not always be trivial.

Obviously there are a lot of other possibilities for such a mechanism
even manipulating other variables interactively.

I discussed the idea with imirkin_ on #dri-devel who agreed that
something like a socket interface would be a reasonable way to
approach the problem, but suggested I toss out the idea on the mailing
list to acquire more thoughts.

I have extensive development experience, but none in the kernel nor
mesa space. If desirable I would be interested in attempting to
implement this idea.
