FBC is disabled through the chicken bits, so I am really curious to know where the power saving is coming from. I just want to verify that we have not made a fundamental mistake in our FBC logic that is consuming more power than is necessary across all platforms. In terms of code clarity, we should leave a note as to why we explicitly disable fbc, e.g.: .has_fbc = 0, /* hardware support is buggy */ -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
