remove generation of EFI properties table

[edk2-devel] [PATCH 0/4] remove generation of EFI properties table

Posted by Ard Biesheuvel 4 years ago

The EFI properties table is broken by design, deprecated, and seems to be
causing confusion as it is unclear to some how it differs from the memory
attributes table (which supersedes it). So let's get rid of the code that
generates it entirely, along with the GUID definitions, PCDs etc.

Due to how the two implementations are intertwined, patch #2 makes the
minimal changes required to stop producing the table (and to allow patch
#3 to remove the associated definitions from MdePkg). Patch #4 is optional
and merges the code together.

For the functionality, it is the same with before for platforms which set PcdPropertiesTableEnable to false by default.
Reviewed-by: Dandan Bi <dandan.bi@intel.com> for patch [PATCH 2/4] [PATCH 3/4] [PATCH 4/4].


If anyone still has the use case of enabling PcdPropertiesTableEnable, please comment.


Thanks,

Thank you Dandan.

Jian, Hao, do you have any comments on this series? If you are too
busy to have a closer look immediately, could you please indicate so
instead of not responding at all? Thanks.

Ard,

My apologies. I was indeed working desperately to catch some deadlines recently.
I agree to remove the properties table.

I cannot remember if there is windows OS still using the properties table.
Maybe Microsoft people can comment.

If no, I agree we can remove the old code.

Jian, Hao, Liming, Michael,

It is not always clear to me how you at Intel divide up the maintainer
duties between yourselves.

Liming and Jiewen have acked this entire series, but they are not the
MdeModulePkg maintainers, so I assume either Jian or Hao should
approve it as well before i can proceed with it.

If this is the case, could Jian and Hao please acknowledge that they
read this email, and perhaps indicate a timeframe within which they
will be able to give their verdict on these changes?

Thanks,
Ard.
