From 01e6fac4d61fdd7fff5433942ec93fc2ea1e4df1 Mon Sep 17 00:00:00 2001 From: Joshua Bakita Date: Wed, 28 Jun 2023 18:24:25 -0400 Subject: Include nvgpu headers These are needed to build on NVIDIA's Jetson boards for the time being. Only a couple structs are required, so it should be fairly easy to remove this dependency at some point in the future. --- include/volt/volt_dev.h | 77 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 77 insertions(+) create mode 100644 include/volt/volt_dev.h (limited to 'include/volt/volt_dev.h') diff --git a/include/volt/volt_dev.h b/include/volt/volt_dev.h new file mode 100644 index 0000000..48d93ae --- /dev/null +++ b/include/volt/volt_dev.h @@ -0,0 +1,77 @@ +/* +* Copyright (c) 2016-2018, NVIDIA CORPORATION.
