Subject: Clarification of Memory management in PEI phase
Date: Thu, 9 Jun 2022 22:58:31 +0530	[thread overview]
Message-ID: <CA+Yfj7sqNuNk4boxx+918EtvxtQUTZH7cdoAo-k-0GX902B-gA@mail.gmail.com> (raw)

Hello everyone,

Can anyone help me with understanding dynamic memory management in PEI
phase? In the UEFI Platform Integration Specification, version 1.7
Errata A, Section 4.6, PEI Memory services are given which include:

1. InstallPeiMemory()
2. AllocatePages()
3. AllocatePool()
4. CopyMem()
5. SetMem()
6. FreePages()

However, no `FreePool()` service seems to be present. So how is the
memory allocated using `AllocatePool()` freed?
