PrmPkg/Include: Fix GCC/CLANG PRM Module DLL Export issues

2025-10-17T06:23:17+00:00

Use _MSC_EXTENSIONS instead of _MSC_VER when MSC specific extensions are required such as __declspec(dllexport). CLANGPDB builds do not set _MSC_VER but CLANGPDB builds in Windows and Linux do support use of MSC specific extensions. Add PRM_EXPORT_DESCRIPTOR macro that provides attributes required to make sure the PRM Export Descriptor Structure is not optimized away by the compiler/linker. PRM_EXPORT_API can not be used for this because the attributes for code and data may be different with different tool chains. For GCC/CLANGDWARF tool chains, PRM_EXPORT_DESCRIPTOR sets the 'used' and 'section(.prmexportdescriptor)' attributes and depends on the GCC linker script to make sure the `.prmexportdescriptor` section is preserved. Fix incorrect location of ; in PRM_MODULE_EXPORT() macro that was found by CLANG. Signed-off-by: Michael D Kinney

PrmPkg: Add ACPI Parameter Data Buffer Signature

2025-06-11T09:13:48+00:00

In PRM spec 1.0 section 4.2.2 ACPI Parameter Buffer defines the signature of ACPI Parameter Data Buffer is 'PRMP'. This commit adds the signature of ACPI Parameter Data Buffer. Signed-off-by: Aaron Li

PrmPkg: Align Data Buffer Signature to Spec

2025-03-12T19:59:59+00:00

edk2's PRM Data Buffer Signature is 'PRMD', however PRM spec 1.0 section 4.2.1 Static Data Buffer indicates that the signature should be 'PRMS'. This commit aligns edk2's signature definition with the spec. Signed-off-by: Oliver Smith-Denny

PrmPkg: Replace PcdPrmPlatformGuid with EDKII_DSC_PLATFORM_GUID

2022-04-05T00:42:38+00:00

Bugzilla request https://bugzilla.tianocore.org/show_bug.cgi?id=2969 was recently completed which causes the PLATFORM_GUID value from the DSC file to be placed into Autogen file .c & .h files. With this change, the PRM Platform GUID can be directly matched to the DSC PLATFORM_GUID value.

PrmPkg: Refactor some PrmLoaderDxe functionality into libraries

2022-04-05T00:42:38+00:00

This change breaks out two sets of responsibilities in PrmLoaderDxe into libraries: * PE/COFF functions -> PrmPeCoffLib * PRM module discovery functions -> PrmModuleDiscoveryLib This is core infrastructure code for PRM functionality that needs to be directly reused and tested in other places. At this time, the primary motivating factor is to use this code in two other locations: 1.) Link the functionality into unit testing modules 2.) Link the functionality into a PRM UEFI application Cc: Andrew Fish Cc: Kang Gao Cc: Michael D Kinney Cc: Michael Kubacki Cc: Leif Lindholm Cc: Benjamin You Cc: Liu Yun Cc: Ankit Sinha Cc: Nate DeSimone Signed-off-by: Michael Kubacki Acked-by: Michael D Kinney Acked-by: Liming Gao Acked-by: Leif Lindholm Reviewed-by: Ankit Sinha

PrmPkg/PrmContextBuffer.h: Add ACPI parameter support structures

2022-04-05T00:42:38+00:00

Adds a new type ACPI_PARAMETER_BUFFER_DESCRIPTOR that can be used by PRM module configuration code to associate a PRM handler GUID with an ACPI parameter buffer allocated by the PRM module configuration code. The ACPI parameter buffer descriptors for a given PRM module are tracked in the firmware internal structure PRM_MODULE_CONTEXT_BUFFERS produced by the module configuration code.

PrmPkg: Remove PRM Module Update Lock

2022-04-05T00:42:38+00:00

Per latest design direction, we've abandoned treating the PRM Module Update Lock as an exported object. There was concern sharing the PRM module address space (where the lock structure resided in a data section) with the OS kernel mode driver. The lock will now be entirely maintained in OS context with interaces to control the lock available to ASL (for _DSM invocation) and OS native code (for direct call).
