From f93565c51fb465aebc34dc52fd704ba038c917f7 Mon Sep 17 00:00:00 2001 From: Mahantesh Kumbar Date: Wed, 22 Aug 2018 16:44:59 +0530 Subject: gpu: nvgpu: add GSP falcon support - Defined FALCON_ID_GSPLITE for GSP falcon. - Created variable gsp_flcn of struct nvgpu_falcon for GSP falcon & registered to falcon module to access falcon functions. - Created HAL file gsp_gv100.c/h for GSP. - Modified Makefile & Makefile.sources files to include gsp_gv100 HAL file. - Enabled GSP falcon support for GV100 by registering to common falcon module. - Defined function gv100_gsp_reset() & assigned to falcon reset as GSP engine reset. - Updated falcon HAL init code not to return error if requested falcon is not supported, instead log the info and return non-error.
