From b62880f7966781eb0b3b1e50f63d6aac362476d3 Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Thu, 23 Feb 2017 18:41:41 +0900 Subject: drm/nouveau/core: add SEC2 engine SEC2 is the name given by NVIDIA to the SEC engine post-Fermi (reasons unknown). Even though it shares the same address range as SEC, its usage is quite different and this justifies a new engine. Add this engine and make TOP use it all post-TOP devices should use this implementation and not the older SEC. Also quickly add the short gp102 implementation which will be used for falcon booting purposes.
