Subject: [edk2-devel] [PATCH v2 00/25] Implement Dynamic Memory Protections
Date: Fri, 18 Aug 2023 15:31:32 -0700 [thread overview]
Message-ID: <20230818223159.1073-1-taylor.d.beebe@gmail.com> (raw)
In the past, memory protection settings were configured via FixedAtBuild PCDs,
which resulted in a build-time configuration of memory mitigations. This
approach limited the flexibility of applying mitigations to the
system and made it difficult to update or adjust the settings post-build.
In a design, the configuration interface has been revised to allow for dynamic
configuration. This is achieved by setting memory protections via a library
interface which stores/updates the memory protection settings in
a GUIDed HOB, which is then consumed during and after DXE handoff.
This patch series adds two libraries:
SetMemoryProtectionsLib: A PEIM that allows for setting/fetching memory
protections and "locking" to prevent further updates via the library interface.
The backing for the settings are a GUIDed HOB that is created by the library
whenever its API is invoked.
GetMemoryProtectionsLib: A DXE library that allows for getting the memory
protection settings for the current boot. This library populates a global
with the settings from the HOB entry (if present) for access in the module.
Previous references to the PCDs are replaced with references to the global.
OvmfPkg has been updated to allow the setting of the memory protection profile
via QemuCfg instead of just the NxForStack setting. If no profile is passed,
the platform will default to the Debug profile for DXE and Off profile for MM.
ArmVirtPkg will use the Release profile.
