* Minor update to patch description
* The changes are based on the new kernel patch [1]
The patch series implements limited support for injecting smart errors for PAPR
NVDIMMs via ndctl-inject-smart(1) command. SMART errors are emulating in
papr_scm module as presently PAPR doesn't support injecting smart errors on an
NVDIMM. Currently support for injecting 'fatal' health state and 'dirty'
shutdown state is implemented. With the proposed ndctl patched and with
corresponding kernel patch [1] following command flow is expected:
$ sudo ndctl list -DH -d nmem0
...
"health_state":"ok",
"shutdown_state":"clean",
...
# inject unsafe shutdown and fatal health error
$ sudo ndctl inject-smart nmem0 -Uf
...
"health_state":"fatal",
"shutdown_state":"dirty",
...
# uninject all errors
$ sudo ndctl inject-smart nmem0 -N
...
"health_state":"ok",
"shutdown_state":"clean",
...
Structure of the patch series
=============================
* First patch updates 'inject-smart' code to not always assume support for
injecting all smart-errors. It also updates 'intel.c' to explicitly indicate
the type of smart-inject errors supported.
* Update 'papr.c' to add support for injecting smart 'fatal' health and
'dirty-shutdown' errors.
