@ -145,3 +145,39 @@ static memory allocation. This is why ACRN removed all ``malloc()``-type code,
and why it needs to pre-identify the size of all buffers and structures used in
the Virtual Memory Manager. For this reason, knowing the available RAM size at
compile time is necessary to statically allocate memory usage.
How to build ACRN on Fedora 29?
*******************************
There is a known issue when attempting to build ACRN on Fedora 29
because of how ``gnu-efi`` is packaged in this Fedora release.
(See the `ACRN GitHub issue
<https://github.com/projectacrn/acrn-hypervisor/issues/2457>`_
for more information.) The following patch to ``/efi-stub/Makefile``
fixes the problem on Fedora 29 development systems (but should
not be used on other Linux distros)::
diff --git a/efi-stub/Makefile b/efi-stub/Makefile
