Hello,

is there an option to make UXA behave as accel=none?

Adding such option if none exists should provide same functionality
(running the X server without possibly triggering any accel bug) with
lower maintenance overhead.

Surely there can be bug in implementing such UXA option but same can
be said for these preprocessor and code checks.

Also can UXA be built without any extra libraries beyond what is
needed for accel=none? Seems there is some drm_intel  dependency.

Thanks

Michal
