Re: [PATCH] drm/amdgpu: refactor code to reuse system information
Validated the code by using the function in same way as ioctl would use in devcoredump and getting the valid values. Also this would be the container of the information that we need to share between ioctl, debugfs and devcoredump and keep updating this based on information needed.

[PATCH] drm/amdgpu: refactor code to reuse system information
Refactor the code so debugfs and devcoredump can reuse the common information and avoid unnecessary copy of it. created a new file which would be the right place to hold functions which will be used between sysfs, debugfs and devcoredump.
