It shouldn't be on the critical path for bringing up userspace (i.e. on the synchronous portion of boot/module loading). Nor should it be delaying bringing up a screen, once the core is initialised we should be able to bring up GT and the display in parallel. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
