Afaik sink crc is a generic DP feature, but obligatory for edp with psr. So would make sense to also run the basic test on other DP ports, just to give it a bit more testing. -Daniel > + c->connection != DRM_MODE_CONNECTED) > + continue; > + > + basic_sink_crc_check(data, connector_id); > + return; > + } > + > + fprintf(stderr, "no eDP with CRC support found\n"); > + igt_fail(1); > +} > + > +igt_simple_main > +{ > + data_t data = {}; > + > + igt_skip_on_simulation(); > + > + data.drm_fd = drm_open_any(); > + > + igt_set_vt_graphics_mode(); > + > + data.resources = drmModeGetResources(data.drm_fd); > + igt_assert(data.resources); > + > + run_test(&data); > + > + drmModeFreeResources(data.resources); > +} > -- > 1.9.0 > > _______________________________________________ > Intel-gfx mailing list > Intel-gfx@xxxxxxxxxxxxxxxxxxxxx > http://lists.freedesktop.org/mailman/listinfo/intel-gfx -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
