Hi! > Original version of the pcilmr utility used values from the Table 8-11 of > the PCIe Base Spec Rev 5.0 to evaluate lanes. But it seems that these > values relate only to the margining equipment and are not relevant to > evaluating the quality of connections. > > Patch set improves grading from two sides: > * The PCIe Base Spec Rev 5.0 sets the minimum values for the eye in the > section 8.4.2. Change default grading values in the utility according to > this section. Keep in mind that the Spec uses full eye width and height > terms and that reference values depend on the current Link speed; > * Manufacturers can provide criteria for their devices that > differ from the standard ones. Usually this information falls under the > NDA, so add an option to the utility that will allow the user to set > necessary criteria for evaluating the quality of lanes. > > At the same time, fix the known limitations associated with arguments > parsing. > > With the new changes made, the logic responsible for arguments parsing has > become too large, so put it in a separate file. Thanks, applied. Martin
