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
