METHOD FOR ADJUSTING UPLINK RX PARAMETERS BASED ON PURLEY PLATFORM

摘要

Provided is a method for adjusting Uplink Rx parameters based on a Purley platform. The method comprises the following steps: stopping the other operations of a CPU, and only responding to a command to modify Rx Eq parameters, and determining a prefix for executing the command to modify the Rx Eq parameters (S1); acquiring states of all the lanes of a current CPU uniPhy part, and confirming a PCIe port number to be adjusted (S2); and acquiring an Rx parameter modification command group and invoking a command in the command group to modify values of corresponding Rx parameters of a PCH end (S3). According to the method, a BIOS needn't be re-written during each modification, and after Rx parameters are modified, a corresponding test of a mainboard can be directly conducted, without re-starting a system, thus improving the work efficiency.
