From 49743df399ca1029f4e22b52e9238d8e25c26bb2 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 7 Jul 2014 16:39:05 +1000 Subject: ui: Add dpy_gfx_check_format() to check backend shared surface support This allows VGA to decide whether to use a shared surface based on whether the UI backend supports the format or not. Backends that don't provide the new callback fallback to native 32 bpp which is equivalent to what was supported before.
