- 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 <rizhao@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1763536 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
