From: Ben Skeggs Date: Fri, 9 Nov 2012 01:25:37 +0000 (+1000) Subject: drm/nvd0/disp: calculate U script id in supervisor interrupt X-Git-Tag: v3.8-rc1~42^2~63 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4a230fa61884ffe6b6a806563eee82f12a60fa1e;p=platform%2Fkernel%2Flinux-stable.git drm/nvd0/disp: calculate U script id in supervisor interrupt This is like we do on nv50:nvd9 already. There's been no problems seen yet with using this *seemingly* scratch register to store the value, but we won't be able to do this anymore once nv50's code is merged.
