* ShellPkg: Add revision check for DSDT Header on ArmEdward Pickup2022-08-241-1/+17
| | | | | | | | | | | | | | | | | Bugzilla: 3995 (https://bugzilla.tianocore.org/show_bug.cgi?id=3995) ACPI 6.4 spec states that if the revision field in the DSDT header is less than 2, then all integers are restricted in width to 32 bits, including in SSDTs. Arm Base boot requirements state that platforms must conform to ACPI 6.3 or later, and that legacy tables are not supported. Adds a check for this field and raise warning if revision is less than 2 on arm. Signed-off-by: Edward Pickup <edward.pickup@arm.com> Reviewed-by: Zhichao Gao <zhichao.gao@intel.com>

| | | | | | | | | | | | | | | | | | | | | | Add host based unit tests for the CpuPageTableLib services. Unit test focuses on PageTableMap function, containing two kinds of test cases: manual test case and random test case. Manual test case creates some corner case to test function PageTableMap. Random test case generates multiple random memory entries (with random attribute) as the input of function PageTableMap to get the output pagetable. Output pagetable will be validated and be parsed to get output memory entries, and then the input and output memory entries will be compared to verify the functionality. The unit test is not perfect yet. There are options for random test, and some of them control the test coverage, and some option are not ready. Will enhance in the future.

When setting PageTableBaseAddress in the entry, the code clears all attributes. 2. Even the ReadWrite bit in parent entry is not set, the code clears the ReadWrite bit in the leaf entry. First change is wrong. It should not change other attributes when setting the PA. Second change is unnecessary.

PML4[0] --> PDPTE[0] --> PDE[0-255] \-> PDPTE[1] --> PDE[0-255] If ReadWrite bit is cleared in PML4[0] and PageTableMap() is called to change [0, 2M] as writable, today's logic doesn't inherit the parent entry's attributes when determining the child entry's attributes. It just sets the PDPTE[0].PDE[0].ReadWrite bit. But since the PML4[0].ReadWrite is 0, [0, 2M] is still read-only. The change fixes the bug. If the inheritable attributes in ParentPagingEntry conflicts with the requested attributes, let the child entries take the parent attributes and loosen the attribute in the parent entry. E.g.: when PDPTE[0].ReadWrite = 0 but caller wants to map [0-2MB as ReadWrite = 1 (PDE[0].ReadWrite = 1), we need to change PDPTE[0].ReadWrite = 1 and let all PDE[0-255].ReadWrite = 0 first.

* PrmPkg: Add details on AArch64 build to the Readme.Jose Marinho2022-08-081-0/+11
| | | | | | | | | | | | | | | Specify how to build the PrmPkg for the AArch64 architecture. Make the 2 following notes: - the PrmPkg has only been tested on AArch64 using the GCC5 toolchain. - All symbols to be listed in the PRMT as well as the PrmModuleExportDescriptor must be explicitly preserved by resorting to the --require-defined linker flag.

| | | | | | | | | | | | | | | | The GenFw invocation with the --prm flag was previously reserved for X64. AArch64 platforms, built with GCC5, can also deploy PRM modules, hence the --prm flag is also applicable in builds targeting the AARCH64 architecture. This commit enables the --prm flag to be used for EDK2 builds targeting AARCH64.
