Especially with atomic it's much neater to just clear our software state (and then applying all the changes we want in one go). But it does get the job done meanwhile, so ack. -Daniel > + > i = 0; > crtc_count = 0; > crtc = crtcs; > -- > 2.9.3 > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@lists.freedesktop.org > https://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 5+ messages in thread

Otoh, something as simple as kms_setmode, one can argue should just be using (cleanly and clearly, ofc) the raw interfaces and iterating over them. kms_setmode_legacy / kms_setcrtc / drm_setcrtc, kms_setmode_atomic, igt_setmode / kms_setmode would all then serve slightly different purposes (both testing and pedagogy). -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 5+ messages in thread
