<p class="MsoNormal">Another thing that was interesting to me is that PcdAcpiTableStorageFile is actually defined in MdeModulePkg and used in MdeModulePkg/Universal/Acpi/AcpiPlatformDxe. Our MinPlatform board packages do not use that driver, we have our own
BoardAcpiDxe that varies with each silicon generation. For that reason I’d be willing to call it a core feature that we have not implemented correctly in our MinPlatform *OpenBoardPkg’s.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It may be a good idea to see if MdeModulePkg/Universal/Acpi/AcpiPlatformDxe is usable in the MinPlatform *OpenBoardPkg’s but that seems like a task for another time.

<p class="MsoNormal">Hi Sai,<br>
There may be a requirement to install board-specific ACPI tables. For example, to support an embedded controller in laptops, or other controllers in servers and desktops.<br>
<br>
In a conversation with Nate about a board port in KabylakeOpenBoardPkg, I said that the options for such boards would be to include AcpiPlatformDxe, or, since BoardAcpiDxe seems to be a superset of AcpiPlatformDxe functionality, add it here by calling PublishAcpiTablesFromFv()
again with this GUID.<br>
<br>
Perhaps an RFC first would have been best. I don't mind dropping this patchset, but can we wait for comments first?<br>
<br>
Best regards,<br>
Benjamin <o:p></o:p></p>
