[PATCH] OvmfPkg: use StatusCode Router and Handler from MdeModulePkg


Cinnamon Shia <cinnamon.shia@...>
 

Use StatusCode Router and Handler from MdeModulePkg instead of
IntelFrameworkModulePkg.

MdeModulePkg ones follows PI spec to implement StatusCode
Router/Handler and provide StatusCode service.
It allows the different status code handlers to be registered.

IntelFrameworkModulePkg one just provides StatusCode service.
It has no Router services.

Thanks for the patch!

I'd like to see a lot more documentation in the commit message. I was
completely unfamiliar with this area before Liming's suggestion and your
patch.

I understand it now, I think, but in retrospect, I just can't fathom why
you guys didn't provide me with more info weeks ago. I've been in the
dark, even though the explanation is fairly simple. :(

(1) So, here's what I would like to see in the commit message:

----------

In the Platform Init v1.4a spec,
- Volume 1 "4.7 Status Code Service" defines the
EFI_PEI_REPORT_STATUS_CODE.ReportStatusCode() service,
- Volume 1 "6.3.5 Status Code PPI (Optional)" defines the
EFI_PEI_PROGRESS_CODE_PPI (equivalent to the above),
- Volume 2 "14.2 Status Code Runtime Protocol" defines the
EFI_STATUS_CODE_PROTOCOL.

These allow PEIMs and DXE (and later) modules to report status codes.

Currently OvmfPkg uses modules from under
"IntelFrameworkModulePkg/Universal/StatusCode/", which produce the above
abstractions (PPI and PROTOCOL) directly, and write the status codes, as
they are reported, to the serial port or to a memory buffer. This is
called "handling" the status codes.

In the Platform Init v1.4a spec,
- Volume 3 "7.2.2 Report Status Code Handler PPI" defines
EFI_PEI_RSC_HANDLER_PPI,
- Volume 3 "7.2.1 Report Status Code Handler Protocol" defines
EFI_RSC_HANDLER_PROTOCOL.

These allow PEIMs and runtime DXE drivers to register several callbacks
for status code handling.

MdeModulePkg offers a PEIM under
"MdeModulePkg/Universal/ReportStatusCodeRouter/Pei" that procudes both
EFI_PEI_PROGRESS_CODE_PPI and EFI_PEI_RSC_HANDLER_PPI, and a runtime DXE
driver under "MdeModulePkg/Universal/ReportStatusCodeRouter/RuntimeDxe"
that produces both EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL.

MdeModulePkg also offers status code handler modules under
MdeModulePkg/Universal/StatusCodeHandler/ that depend on
EFI_PEI_RSC_HANDLER_PPI and EFI_RSC_HANDLER_PROTOCOL, respectively.

The StatusCodeHandler modules register themselves with
ReportStatusCodeRouter through EFI_PEI_RSC_HANDLER_PPI /
EFI_RSC_HANDLER_PROTOCOL. When another module reports a status code
through EFI_PEI_PROGRESS_CODE_PPI / EFI_STATUS_CODE_PROTOCOL, it reaches
phase-matching ReportStatusCodeRouter module first, which in turn passes
the status code to the pre-registered, phase-matching StatusCodeHandler
module.

The status code handling in the StatusCodeHandler modules is identical
to the one currently provided by the IntelFrameworkModulePkg modules.
Replace the IntelFareworkModulePkg modules with the MdeModulePkg ones,
so we can decrease our dependency on IntelFareworkModulePkg.

----------

(3) Any particular reason that you add the replacement text under the
Pcd.inf module? In all the other places, the replacements are more focused.

Looks good to me otherwise. Can you please submit a v2?

Thanks!

- Volume 1 "4.7 Status Code Service" defines the
EFI_PEI_REPORT_STATUS_CODE.ReportStatusCode() service,
sorry, the above is a typo, I meant EFI_PEI_SERVICES.ReportStatusCode().


- Volume 1 "6.3.5 Status Code PPI (Optional)" defines the
EFI_PEI_PROGRESS_CODE_PPI (equivalent to the above),
- Volume 2 "14.2 Status Code Runtime Protocol" defines the
EFI_STATUS_CODE_PROTOCOL.

These allow PEIMs and DXE (and later) modules to report status codes.

Currently OvmfPkg uses modules from under
"IntelFrameworkModulePkg/Universal/StatusCode/", which produce the above
abstractions (PPI and PROTOCOL) directly, and write the status codes, as
they are reported, to the serial port or to a memory buffer. This is
called "handling" the status codes.

In the Platform Init v1.4a spec,
- Volume 3 "7.2.2 Report Status Code Handler PPI" defines
EFI_PEI_RSC_HANDLER_PPI,
- Volume 3 "7.2.1 Report Status Code Handler Protocol" defines
EFI_RSC_HANDLER_PROTOCOL.

These allow PEIMs and runtime DXE drivers to register several callbacks
for status code handling.
The woring here would also be better if we said "These allow several
PEIMs and runtime DXE drivers to register callbacks for status code
handling". In other words, "several" should refer to the drivers, not
the callbacks.


MdeModulePkg offers a PEIM under
"MdeModulePkg/Universal/ReportStatusCodeRouter/Pei" that procudes both
EFI_PEI_PROGRESS_CODE_PPI and EFI_PEI_RSC_HANDLER_PPI, and a runtime DXE
driver under "MdeModulePkg/Universal/ReportStatusCodeRouter/RuntimeDxe"
that produces both EFI_STATUS_CODE_PROTOCOL and EFI_RSC_HANDLER_PROTOCOL.

MdeModulePkg also offers status code handler modules under
MdeModulePkg/Universal/StatusCodeHandler/ that depend on
EFI_PEI_RSC_HANDLER_PPI and EFI_RSC_HANDLER_PROTOCOL, respectively.

The StatusCodeHandler modules register themselves with
ReportStatusCodeRouter through EFI_PEI_RSC_HANDLER_PPI /
EFI_RSC_HANDLER_PROTOCOL. When another module reports a status code
through EFI_PEI_PROGRESS_CODE_PPI / EFI_STATUS_CODE_PROTOCOL, it reaches
phase-matching ReportStatusCodeRouter module first, which in turn passes
"it reaches [the] phase-matching" -- the definite article missing.

Sorry about these typos, it was very late last night when I wrote the email.

Thanks!

the status code to the pre-registered, phase-matching StatusCodeHandler
module.

The status code handling in the StatusCodeHandler modules is identical
to the one currently provided by the IntelFrameworkModulePkg modules.
Replace the IntelFareworkModulePkg modules with the MdeModulePkg ones,
so we can decrease our dependency on IntelFareworkModulePkg.
