Not supporting fbdev looks more like an accident than intention here, and maybe a good reason to have these kind of must-past lists. Eventually, once the i915-ism is worked out of igt well enough for a set of tests at least. The drm/ci effort should help in building up that list (by essentially extracting the common set of tests that everyone passes and graduating that to the must-pass list for kms conformance or whatever we'll call it). -Daniel > > Best regards > Thomas > > > > > Maxime > > -- > Thomas Zimmermann > Graphics Driver Developer > SUSE Software Solutions Germany GmbH > Maxfeldstr. 5, 90409 Nürnberg, Germany > (HRB 36809, AG Nürnberg) > Geschäftsführer: Ivo Totev -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch
