From 7f14aafc2c02eb0fab458324d0ba91a7fdea3086 Mon Sep 17 00:00:00 2001 From: Richard Zhao Date: Tue, 26 Jun 2018 17:37:40 -0700 Subject: gpu: nvgpu: rework ecc structure and sysfs - create common file common/ecc.c which include common functions for add ecc counters and remove counters. - common code will create a list of all counter which make it easier to iterate all counters. - Add chip specific file for adding ecc counters. - add linux specific file os/linux/ecc_sysfs.c to export counters to sysfs. - remove obsolete code - MISRA violation for using snprintf is not solved, tracking with jira NVGPU-859 Jira NVGPUT-115 Change-Id: I1905c43c5c9b2b131199807533dee8e63ddc12f4 Signed-off-by: Richard Zhao Reviewed-on: https://git-master.nvidia.com/r/1763536 Reviewed-by: mobile promotions Tested-by: mobile promotions --- drivers/gpu/nvgpu/gp10b/ecc_gp10b.c | 106 ++++++++++++++++++++++++++++++++++++ 1 file changed, 106 insertions(+) create mode 100644 drivers/gpu/nvgpu/gp10b/ecc_gp10b.c (limited to 'drivers/gpu/nvgpu/gp10b/ecc_gp10b.c') diff --git a/drivers/gpu/nvgpu/gp10b/ecc_gp10b.c b/drivers/gpu/nvgpu/gp10b/ecc_gp10b.c new file mode 100644 index 00000000..cf95c0d7 --- /dev/null +++ b/drivers/gpu/nvgpu/gp10b/ecc_gp10b.c @@ -0,0 +1,106 @@ +/* + * Copyright (c) 2018, NVIDIA CORPORATION.
