Code assumes that it's valid.
However this still leaves open a hole in case a modeset changes active_crtcs during the first commit. intel_state->active_crtcs is set at the same time intel_state->modeset is, so resend with if (!intel_state->modeset) intel_state->active_crtcs = dev_priv->active_crtcs; ? ~Maarten _______________________________________________ Intel-gfx mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/intel-gfx
