Subject: Support for ACPI 1.0
Date: Tue, 15 Nov 2016 13:08:25 +0000 [thread overview]
Message-ID: <AM5PR0801MB17629FE0309DAADF0CACC4DD8BBF0@AM5PR0801MB1762.eurprd08.prod.outlook.com> (raw)
There is some wonderfully convoluted code in MdeModulePkg/Universal/Acpi/AcpiTableDxe/AcpiTableProtocol.c
A major cause of the complexity arises from the special cases related to support for "EFI_ACPI_TABLE_VERSION_1_0B" or not ("ACPI_TABLE_VERSION_GTE_2_0").
We are seeing problems (SCT fails) related to this with the current code, and have been looking at a fix.
However, it seems reasonable to question the requirement to support ACPI 1.0 nowadays.
Is there any need to retain support for such obsolete table versions?
Should there be, could it at least be split out into a distinct build option?
Regards,
Evan
