[edk2] [PATCH edk2-platforms] Platform/ARM: remove ReportStatusCodeLib resolutions
Posted by Ard Biesheuvel 7 years, 2 months ago 
The generic ResetSystemRuntimeDxe may invoke ReportStatusCodeLib, and
this may happen at runtime. If the chosen resolution is not suitable
for runtime, this will result in a crash.

Given that we don't actually use status codes, let's just switch to
the NULL instance for all modules and be done with it.

Ard:
  MdeModulePkg\Library\RuntimeDxeReportStatusCodeLib\RuntimeDxeReportStatusCodeLib.inf is designed for Runtime driver. If you require StatusCode at runtime, you can use this library instance. 

Thanks

Thanks Liming.

I wrongly assumed that these platforms have no use for status code,
but apparently, it is required for the FPDT table?

Ard:
  MdeModulePkg\Universal\Acpi\FirmwarePerformanceDataTableDxe depends on some status code to fill basic boot FPDT record in FPDT table. Those status codes are reported from DxeCore. For FPDT table, DxeCore must link the real report status code. It links DXE version library instance.

Ard,


BaseReportStatusCodeLibNull.inf was replaced with DxeReportStatusCodeLib.inf to support storing boot performance data required for FPDT ACPI table.

As Liming already mentioned ResetSystemRuntimeDxe.inf should be linked to RuntimeDxeReportStatusCodeLib library:


  MdeModulePkg/Universal/ResetSystemRuntimeDxe/ResetSystemRuntimeDxe.inf {
    <LibraryClasses>
      ReportStatusCodeLib|MdeModulePkg/Library/RuntimeDxeReportStatusCodeLib/RuntimeDxeReportStatusCodeLib.inf
  }

Alexei.

I know how it works. I just was not aware that we used status codes
for anything.

I see there's some active discussion yet. But FWIW,
