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/os/linux/debug_pmgr.c | 104 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 104 insertions(+) create mode 100644 include/os/linux/debug_pmgr.c (limited to 'include/os/linux/debug_pmgr.c') diff --git a/include/os/linux/debug_pmgr.c b/include/os/linux/debug_pmgr.c new file mode 100644 index 0000000..c264978 --- /dev/null +++ b/include/os/linux/debug_pmgr.c @@ -0,0 +1,104 @@ +/* + * Copyright (c) 2018, NVIDIA CORPORATION.
