It's possible that different steppings of the same generation will have the same test scan files, with the extended signature informing that they are valid for this stepping too (see find_matching_signature())), because these files are going to be pretty big, in the order of a hundred MB each. That means we will either see symlinked or hardlinked files in the directory. If you blindly try them all, you're going to spend twice or three times as long as necessary to complete the scan. With the timeout in question for at least Sapphire Rapids, we're talking about a difference measured in hours. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering
