Hi list, Recently I have a report for a warning message from CXL subsystem, [ 48.142342] cxl_port port2: Couldn't locate the CXL.cache and CXL.mem capability array header. [ 48.144690] cxl_port port3: Couldn't locate the CXL.cache and CXL.mem capability array header. [ 48.144704] cxl_port port3: HDM decoder capability not found [ 48.144850] cxl_port port4: Couldn't locate the CXL.cache and CXL.mem capability array header. [ 48.144859] cxl_port port4: HDM decoder capability not found [ 48.170374] cxl_port port6: Couldn't locate the CXL.cache and CXL.mem capability array header. [ 48.172893] cxl_port port7: Couldn't locate the CXL.cache and CXL.mem capability array header. [ 48.174689] cxl_port port7: HDM decoder capability not found [ 48.175091] cxl_port port8: Couldn't locate the CXL.cache and CXL.mem capability array header. [ 48.175105] cxl_port port8: HDM decoder capability not found
After checking the source code I realize this is not a real bug, just a warning message that expected device was not detected. But from the above warning information itself, users/customers are worried there is something wrong (IMHO indeed not). Is there any chance that we can improve the code logic that only printing out the warning message when it is really a problem to be noticed? Thanks in advance. Coly Li
