# Preface Please ensure you have read the [contribution docs](https://github.com/microsoft/mu/blob/master/CONTRIBUTING.md) prior to submitting the pull request. In particular, [pull request guidelines](https://github.com/microsoft/mu/blob/master/CONTRIBUTING.md#pull-request-best-practices). ## Description The original implementation is missing a step of populating the temporary stack pointer during the C3 resumption process. This would impact the operations involving stack movements (local variables, calls and returns), until the long jump occurs. This change is adapted from the assembly `ApEntryPoint` routine from `ArmPsciMpServicesDxe.inf` to mitigate such null-stack window during C3 resumption. For each item, place an "x" in between `[` and `]` if true. Example: `[x]`. _(you can also check items in the GitHub UI)_ - [x] Impacts functionality? - [ ] Impacts security? - [ ] Breaking change? - [x] Includes tests? - [ ] Includes documentation? ## How This Was Tested The change was tested on Q35 and FVP virtual platforms as well as proprietary physical platforms. ## Integration Instructions N/A |

UEFI Testing Package
About
This package adds tests.
System Functional tests
Tests that invoke system functions and query system state for verification.
MemmapAndMatTestApp
This test compares the UEFI memory map and Memory Attributes Table against known requirements. The MAT has strict requirements to allow OS usage and page protections.
MorLockTestApp
This test verifies the UEFI variable store handling of MorLock v1 and v2 behavior.
SmmPagingProtections
This test verifies the SMM paging attributes by invoking operations that should cause cpu exceptions if the memory protections
are in place. The SMM cpu exception handler needs to be configured to force reset on trap to allow automated testing.
See UefiCpuPkg/Include/Protocol/SmmExceptionTestProtocol.h, gUefiCpuPkgTokenSpaceGuid.PcdSmmExceptionRebootInsteadOfHaltDefault,
and gUefiCpuPkgTokenSpaceGuid.PcdSmmExceptionTestModeSupport.
System Audit tests
UEFI applications that collect data from the system and then that data can be used to compare against known good values.
UefiVarLockAudit
Audit collection tool that gathers information about UEFI variables. This allows auditing the variables within a system, checking attributes, and confirming read/write status. This information is put into an XML file that allows for easy comparison and programmatic auditing.
UEFI
UEFI shell application that gets the current variable information from the UEFI shell and creates an XML file.
Windows (UEFI)
Python script that can be run from the Windows OS. It takes the UEFI created XML file as input and then queries all listed variables and updates the XML with access and status codes. This gives additional verification for variables that may employ late locking or other protections from OS access.
TpmEventLogAudit
Audit tool to collect the TPM Event Log from the system in standard format. It can then be programmatically compared against a known event log for the given system. Easy this that can be tested are the number of events in some PCRs, confirm that all PCRs should be capped, etc.
SMMPagingAudit
Audit tool creates a human readable description of the SMM page tables and memory environment.
App
UEFI shell application collects information from SMM and writes it to files.
SMM
SMM Library linked into SMM driver used to collect information about SMM environment. Activated by the shell app collects IDT, GDT, page tables, and loaded images.
Windows (SMM)
Python scripts that process the files generated by the UEFI app and output a report for verification and analysis.
