* MdePkg: Move CompilerIntrinsicsLib from ArmPkgOliver Smith-Denny2024-09-122-4/+2
| | | | | | | | | | | | | | | | | | | | As per the emailed RFC in https://edk2.groups.io/g/devel/topic/rfc_move/107675828, this patch moves CompilerIntrinsicsLib from ArmPkg to MdePkg as this library provides compiler intrinsics, which are industry standard. This aligns with the goal of integrating ArmPkg into existing packages: https://bugzilla.tianocore.org/show_bug.cgi?id=4121. The newly placed CompilerIntrinsicsLib is added to MdeLibs.dsc.inc as every DSC that builds ARM/AARCH64 needs this library added. The old location is removed from every DSC in edk2 in this commit also to not break bisectability with minimal hoop jumping.

* PrmPkg: Don't Set Access Attributes of Runtime MMIO RangesTaylor Beebe2024-07-241-1/+6
| | | | | | | | | | | | Passing in access attributes to SetMemorySpaceAttributes() will cause the existing attributes to be overwritten. The MMIO region should have the appropriate attributes applied during memory protection initialization and the attributes of the memory space descriptor are inaccurate. Don't pass in any CPU arch attributes so SetMemorySpaceAttributes() doesn't subsequently call gCpu->SetMemoryAttributes(). Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>

* PrmPkg: CI: Add PrEval entryJoey Vagedes2023-10-231-0/+3
| | | | | | | | | | | | | | | | | | | Adds a PrEval entry to the package's ci.yaml file which is used to verify if the package uses a particular library instance when that library instance file (INF) is updated. When a library instance file (INF) is updated, PrEval will review each package's DSC as described in the ci.yaml file to determine if the package uses said library instance. If the package does use the library instance, it will be built and tested to ensure the package is not broken from the change.

Confirm that their firmware port of the PRM infrastructure implemented in this package is functioning correctly. 2. Quickly get information about what PRM modules and handlers are present on a given system. 3. Quickly test PRM handlers without booting to a fully featured operating system. 4. Develop and exercise PRM handlers prior to the availability of an operating system that is PRM aware. Adds a brief section to Readme.md about the PrmInfo UEFI application with a link to allow the reader to find more information about the application if interested.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PRM_MODULE_EXPORT parameterized macro allows a caller to produce a static PRM module export descriptor structure in the binary by simply passing PRM_HANDLER_EXPORT_ENTRY arguments with each argument representing a PRM handler to be exported by the module. Previously, the PRM_MODULE_EXPORT_DESCRIPTOR_STRUCT used in the PRM_MODULE_EXPORT macro was fixed to a maximum of three handlers. This change removes that restriction and allows the structure to grow based on the number of PRM handlers given to the macro. This means a local type will be customized per PRM module. The reference type PRM_MODULE_EXPORT_DESCRIPTOR_STRUCT keeps a field at the end that allows array access to PRM_HANDLER_EXPORT_DESCRIPTOR_STRUCT members.

* PrmPkg: Add ALLOCATE_CONTEXT_BUFFER_IN_FW build optionMichael Kubacki2022-04-056-12/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's currently two approaches being considered for how to allocate the context buffer passed to PRM handlers: 1. The context buffer is allocated and populated in firmware. As such, the FW converts all pointers internal to the buffer to virtual memory addresses at the virtual address change event. A single context buffer pointer is given to the OS via the PRM ACPI table and the OS converts this single physical address to a virtual address when it passes the context buffer as a pointer to PRM handlers. 2. The context buffer is allocated and populated in the OS. The OS gets all the information needed to populate the context buffer from other pre-existing resources (mainly physical addresses in the PRM ACPI table). The OS converts all the physical addresses to virtual addresses, allocates the context buffer instances, and fills in the information. The OS passes the context buffer virtual address to PRM handlers. The prior behavior was (1). The current POR behavior has moved to (2). Until (2) is used more widely, it can be kept around with fairly minimal overhead via a build flag in a few places. So the default behavior is now (2) (the expected permanent behavior) with (1) easily enabled by defining "ALLOCATE_CONTEXT_BUFFER_IN_FW" in the compiler defined macros. A DSC define was added in PrmPkg.dsc to set this compiler macro in the package build. At some point in the future, all code (and some peripheral code) surrounded with this build flag can be removed if (2) is fully decided upon.
