Subject: [PATCH 187/217] cxl/test: add a test to {read,write,zero}-labels
|
|
|
26ccd9 |
|
|
|
26ccd9 |
Add a unit test to test writing, reading, and zeroing LSA aread for
|
|
|
26ccd9 |
cxl_test based memdevs using ndctl commands, and reading using cxl-cli
|
|
|
26ccd9 |
commands to exercise that route as much as possible.
|
|
|
26ccd9 |
|
|
|
26ccd9 |
Note that writing using cxl-cli requires a bit more enabling to enable,
|
|
|
26ccd9 |
as the corresponding nvdimm-bridge object will need to be disabled
|
|
|
26ccd9 |
first.
