The Paging Audit has a bad call pattern for GetMemoryMap(): it assumes that the unmerged memory map size is within 20% larger than the merged memory map size (i.e. the first call to GetMemoryMap() with size 0 and the subsequent call). Instead, always use the unmerged size + 20% as the safe size to use. Otherwise we can fail because we say we have too small a buffer. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
This adds support for running the paging audit on X64 Patina systems. The only change required is adding self map parsing instead of physical page table map parsing. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
There was a flawed test in the paging audit that tried to confirm that memory outside of the EFI_MEMORY_MAP was marked as RP, but it did not have all the information needed to determine this. The test was removed from the simplified tests in the test app in microsoft@5beccf1 but it was not removed from the full paging audit. This removes the test from the full audit.

The Paging Audit Python script has a bad assumption that the only RO Data should be the GDT/IDT. However, this is incorrect for Patina, it marks any image section that is not marked writeable as RO, so we will end up with RO Data sections. This commit correctly reports that instead of specifying an error. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
The DxeMemoryProtectionTestApp relies on a Project Mu produced protocol to search images. However, this is not required for Patina and the debug image info table can be used instead. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
This adds self mapped page table walking to the AARCH64 paging audit test app. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>
This commit adds self map page table walking for X64 in the simple paging audit test case. The logic was copied from CpuPageTableLib and self map logic added. Signed-off-by: Oliver Smith-Denny <osde@microsoft.com>

Description
See individual commit descriptions for full details. This changeset updates the paging audit simple test, full audit, and memory protections test app to run on Patina.
How This Was Tested
Tested on physical Intel, Q35, and SBSA.
Integration Instructions
Ensure the platform is producing the memory protection HOB with:
Until Patina enables those features, otherwise those tests will execute and will fail due to no guard pages enabled.
