From 6d124ff845334bc466f56c059147e7ad587c2e7e Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Mon, 3 Apr 2017 10:33:01 +0200 Subject: drm: Add acquire ctx to ->gamma_set hook MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Atomic helpers really want this instead of the hacked-up legacy backoff trick, which unfortunately prevents drivers from using their own private drm_modeset_locks. Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which don't yet use the new atomic color mgmt/gamma table stuff. Would be nice if they could switch over and just hook up drm_atomic_helper_legacy_gamma_set() instead.
