Subject: [PATCH 206/217] cxl/test: Validate switch port settings in
|
||
|
|
cxl-region-sysfs.sh
|
||
|
|
|
||
|
|
A recent kernel fix to add the missing update of endpoint decoder HPA range
|
||
|
|
settings regressed switch decoder HPA range settings. Add validation for
|
||
|
|
switch port settings to avoid regressions like that going forward.
