Absolutely. I was just trying to narrow down whether your 'keeping IA32' meant just keeping it in working order, or have it keep up with future enhancements. My intent is to implement an optional PPI that will be used by the PEI image loader to map PE code and data sections with the appropriate permissions if they are suitably aligned. Only the DXE core would generally fit this description, but there is no reason to disallow this for shadowed PEIMs that happen to be built as PE32 binaries with 4k section alignment (although I'm not convinced of the value add there) If the PPI is not exposed (for any reason) things should just keep working as they do today. Given that OVMF no longer functionally depends on IA32 PEI, we simply won't bother to implement the PPI at all for IA32. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
