July 4, 2021 FIO Allocating Memory Above 2GB Some UEFI implementations, notably those based on IP from AMI, have a limitation on the amount of memory available for allocation via the gBS->AllocatePool and gBS->AllocatePages(AllocateAnyAddress, ...) APIs. Specifically they won't allow allocation of any memory above about 2GB, regardless of allocation size. Furthermore, some implementations (such as on the ASUS Z170) appear to have a catastrophic failure whereby if a module causes the system to run out of memory under 2GB the system subsequently becomes unbootable and must be recovered using the ASUS Flashback feature, or RMA'd.

July 4, 2021 Developing EDK2 code using FreeBSD The EDK2 doesn't work out-of-the-box with FreeBSD, but needs some extra packages and setup. Packages to install are: shells/bash devel/binutils lang/gcc5, or newer devel/nasm devel/acpica-tools devel/git devel/gmake lang/python27 databases/py27-sqlite3 Create the following symlinks in BaseTools/Bin/FreeBSD-amd64: python -> /usr/local/bin/python2.7 make -> /usr/local/bin/gmake ld -> /usr/local/bin/ld objcopy -> /usr/local/bin/objcopy gcc -> /usr/local/bin/gcc5 g++ -> /usr/local/bin/g++5 gcc-ar -> /usr/local/bin/gcc-ar5 gcc-nm -> /usr/local/bin/gcc-nm5 gcc-ranlib -> /usr/local/bin/gcc-ranlib5 After that, you should be able to use the EDK2 as you would on a Linux system as long as you use bash - for example: Read more
