Subject: [PATCH 0/8] StandaloneMmPkg: assorted fixes and improvements
Date: Fri, 4 Jan 2019 12:03:07 +0100 [thread overview]
Message-ID: <20190104110315.18339-1-ard.biesheuvel@linaro.org> (raw)
This series addresses a number of issues I ran into while bringing up
the standalone MM based authenticated variable store on the SynQuacer
(AArch64) platform.
The first six patches are obvious fixes/improvements.
Patch #7 adds support for TE formatted MM_CORE_STANDALONE binaries.
This is useful given that the 4 KB section alignment we require in
AArch64 implementations of standalone MM (due to the strict separation
between code and date) results in 8 KB of wasted space at the start of
the firmware volume. This can be reduced to 4 KB when using a TE image
and the FIXED attribute in the associated [Rule] section, by leveraging
an existing optimization in the FFS generation code that aligns TE images
by reducing FFS padding rather than adding more.
Patch #8 is another space optimization: it reuses the existing support
for encapsulated compressed firmware volumes in FFS files to shrink the
size of the primary standalone MM FV considerably. Again, due to
alignment requirements, there is significant bloat in the uncompressed
images (4 KB for the PE/COFF header, and up to 4 KB per section for the
.text, .data and .reloc sections), making the absolute minimum size of
any trivial MM_STANDALONE module 16 KB.
