about PCI Hardware Compliance Test - Display RRS feed

  • 問題

  • 您好

    请问一个有关PCI Hardware Compliance Test - Display fail的问题,如下:

    在run PCI Hardware Compliance Test - Display时,一个sub task “Power Management Capability” fail,下面是fail的信息:

    Start Test 12/25/2009 10:25:58.173 AM Power Management Capability
    Error 12/25/2009 10:25:58.173 AM Device is filtered by ID on test section 'Power Management Capability' with a failure because of known incompatibilities with the test.
    File:   <Unspecified file> Line: 0
    Error Type:   NT_STATUS
    Error Code:   0xc0000420
    Error Text:   Error 0xc0000420

    我用PCIScope看了一下PCI register - PM Capabilities的值,发现version的值为2,即此display card支持power management interface specification 1.1。
    我用另外一块display card跑同样的job,可以pass。此卡的version的值为3,即支持power management interface specification 1.2。

    是不是说WLK1.4 follow的是power management interface specification 1.2,而对一些只支持power management interface specification 1.1的旧卡不做Power Management Capability test?
