For userspace to discover this, they should just use trial and error during startup (using the legacy SetCursor)? Though the easiest way would cause the cursor to flicker - just hope the cursor is off/invisible on startup. Code makes a lot of sense after all the refactoring, but I'll leave the register checking to somebody else unless they are lazier than I am. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
