H A Ddebugfs-cxl7 attribute, the memdev driver sends an inject poison command to
9 aligned and the length of the injected poison is 64-bytes. If
10 successful, the device returns poison when the address is
11 accessed through the CXL.mem bus. Injecting poison adds the
13 to Injected. In addition, the device adds a poison creation
16 It is not an error to inject poison into an address that
17 already has poison present and no error is returned. If the
29 attribute, the memdev driver sends a clear poison command to
30 the device for the specified address. Clearing poison removes
33 poison from an address that does not have poison set. If the
