SubjectRe: [PATCH v8 5/5] powerpc/papr_scm: Implement support for PAPR_SCM_PDSM_HEALTH
Date
Vaibhav Jain <vaibhav@linux.ibm.com> writes:

> This patch implements support for PDSM request 'PAPR_SCM_PDSM_HEALTH'

> ND_CMD_CALL. This functionality is implemented in newly introduced
> papr_scm_get_health() that queries the scm-dimm health information and

> The patch also introduces a new member 'struct papr_scm_priv.health'
> thats an instance of 'struct nd_papr_pdsm_health' to cache the health
> information of a nvdimm. As a result functions drc_pmem_query_health()
> and flags_show() are updated to populate and use this new struct
> instead of a u64 integer that was earlier used.
