Hi Edhay,

 

Do you have any more questions?

What do you think of creating another directory in edk2-test, for other test apps, in addition to uefi-sct, such as ResumeOK.efi?

 

Thanks,

Hi Edhay,

 

ResumeOK.efi is a tool I wrote from the HelloWorld example, that validates Windows resume from S4 requirements, specifically that the memory-map run-time memory regions don’t change, and secondly that PCI devices don’t disappear from the system, both conditions would cause Windows to fail to resume from S4.

 

You install the tool to the root of the ESP, and set it as the default/top entry in the boot manager, and launch it.  (Disable Secure Boot.)

 

It runs warm, cold, and 60s ACPI RTC wake cycles, infinitely looking for errors.

 

ResumeOK.efi writes a file to the root of the ESP, ResumeOK.map, which contains the ACPI Facs->HardwareSignature, a list of the PCI devices in the system, and a copy of its memory map, from the first time it runs.

 

During each test pass, it runs a barrage of tests:

 

1. Free memory test – does the available memory match the memory map saved in ResumeOK.map
2. HW signature check – does the system still have the same HW signature as saved in the ResumeOK.map
3. Allocation test – all the available memory is allocated, and then the memory map is checked if the run-time regions match ResumeOK.map.

 

If any of the tests fail, then the new/missing PCI devices are listed (HW signature fail case), or the memory descriptor that changed, it’s location, and current and previous type and size.

 

I have received permission from Intel to *try* to release the source under Edk2-test.

 

I’ve included a 64-bit binary, if you want to give it a test drive.

 

Make sure Secure Boot is off.

Also, it is required to manually delete any ResumeOK.map on the ESP, before beginning a new test pass.

 

The tool also supports a host of EFI Shell commands:

 

Resumeok.efi MEMMAP – displays Windows coalesced view of the current memory map

ResumeOK.efi ROKMAP – displays Windows coalesced view of the memory saved in ResumeOK.map

ResumeOK.efi RTDATA – displays an analysis of RT_Data pool usage

ResumeOK.efi NORESET – run one test pass, but suppress automatic SX cycling

 

These are the files that build it:

Hi Eric,

 

    Thanks for reaching out to us.

Can we get more details of the tool?

 

Is this tool already open sourced or could you send us the basic documentation pertaining to it.

 

With Warm Regards,
Edhay
