From 19fdb429c2b04d13faecad8b2e5466e9f3c7b8c7 Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Wed, 29 Mar 2017 15:00:24 -0700 Subject: gpu: nvgpu: Wrappers for checking platform type Add nvgpu_* wrappers for determining if we're running in simulation or silicon, and if we're running in hypervisor. The new wrappers require struct gk20a pointer, and gk20a_fence_wait() did not have access to one. Add struct gk20a pointer as the first parameter.
