    Reducing FSP performance time

    IntelForum Community Member

      Hi,

       

      We are building a FSP integrated coreboot image. We are using Intel FSP 2.0.

      While booting the coreboot image we get the following FSP performance data logs.

       

      Coreboot FSP Performance Data

      ID: 950 - 951: 2347842343 - 2126500026 --> 170ms   

      ID: 952 - 953: #^!1175958314 - 3141289776 --> 1792ms

      ID: 954 - 955: #^!1702555243 - #^!1465185826 --> 182ms 

      ID: 956 - 957: #^!1094328449 - #^!1091128442 --> 2ms   

       

      ID:952 – 953 is FSP_TEMP_RAM_EXIT which takes around 1.7 sec. Below are the queries:

       

      1. What is happening in FSP_TEMP_RAM_EXIT phase ?
      2. Can we reduce this time further ?

       

      Please provide your feedback.

       

      Thanks & Regards,

        Antony
