* gpu: nvgpu: rework ecc structure and sysfsRichard Zhao2018-07-19
| | | | | | | | | | | | | | | | | | | | | - 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>
* gpu: nvgpu: update ecc sysfs node handlingNitin Kumbhar2018-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Make ecc sysfs hash table per GPU by adding it as part of nvgpu_os_linux. Using a single hash table might give incorrect results as GPUs have same filenames and a filename is used as a key for a lookup. Add device_attribute as part of struct gk20a_ecc_stat. Using a single array of pointers of device attribute for an ecc_stat results in memory leak and incorrect stats if multiple GPUs are present on the system. This array of pointers will always hold info for GPU which created sysfs nodes last. Fix this by making device attribute array per ecc stat per GPU. Fix ecc stat removal to consider zero sub-units for a given number of hwunits. The multiplication with zero results in not removing any sysfs node at all.

* gpu: nvgpu: Fold T19x code back to main code pathsTerje Bergstrom2018-01-23
| | | | | | | | | | | | | Lots of code paths were split to T19x specific code paths and structs due to split repository. Now that repositories are merged, fold all of them back to main code paths and structs and remove the T19x specific Kconfig flag.
