> Subject: [edk2-devel] [PATCH v1 00/41] Add PrmPkg
>
> From: Michael Kubacki <michael.kubacki at microsoft.com>
>
> This patch series adds a new package called PrmPkg. An RFC was sent to the
> edk2 mailing list on January 28, 2022 detailing the proposal, see
> https://edk2.groups.io/g/devel/message/86181.
>
> Platform Runtime Mechanism (PRM) is a new firmware solution that has
> been developed in edk2-staging/PlatformRuntimeMechanism.
>
> This patch series has been organized to greatly condense the history from
> the edk2-staging branch but to preserve important decisions and changes in
> history that help establish context of changes and will serve as valuable
> references for future development.
>
> Interest in PRM has increased across various vendors and we believe it is
> beneficial to make the source code more widely available for the following
> reasons:
>
> 1. PRM specification adoption
> 2. Feature completeness
> 3. Overall validation coverage
> 4. Interest from the community and future collaboration
>
> The technical details of PRM are covered in the PRM Specification in addition
> to the Readme.md file located in the root of PrmPkg in this patch series.
>
> 1. PRM specification adoption
>
> Intel and Microsoft have worked together to standardize PRM in the ACPI
> Specification and the PRM Specification hosted on uefi.org.
>
> * ACPI 6.4 Specification:
> https://uefi.org/node/4149
>
> * PRM Specification:
>
> https://uefi.org/sites/default/files/resources/Platform%20Runtime%20Mec
> hanism%20-%20with%20legal%20notice.pdf
>
> 2. Feature completeness
>
> PrmPkg implements the full firmware functionality described in the PRM
> Specification and there are no significant changes to functionality planned at
> this time.
>
> Though we are very much interested in evolving PRM based on feedback.
>
> 3. Overall validation coverage
>
> PrmPkg has been integrated and tested on client and server systems in
> addition to virtual platforms (OvmfPkg/QEMU).
>
> Platform integration is simple and a demonstration of this integration for
> OvmfPkg is available in the following branch:
> https://github.com/makubacki/edk2/tree/ovmf_prmpkg_integration
>
> The code has been built with:
> * MSFT VS2015, VS2017, and VS2019
> * GCC5 (see https://bugzilla.tianocore.org/show_bug.cgi?id=3802)
> * iASL compiler (20200528 - https://acpica.org/node/181)
>
> The Linux kernel currently includes the following PRM support:
> * _OSC PRM bit - allows FW to know determine the OS is
> PRM-capable and can redirect _DSM method from alternate
> triggers (such as SMI) to PRM.
> * PRM invocation via _DSM, includes PRM module and handler parsing
> from ACPI PRMT table, and also the PRM operation region handler
> for runtime PRM service invocation.
> * An OS configuration for PRM enabling, PRM support can be
> disabled during OS image build.
>
> Note that upstream Linux does not currently support the following:
> * Ability for the OS driver to call a PRM handler directly,
> it has to be via ACPI _DSM.
> * Run time update PRM module and handler via PE/COFF PRM image.
>
> This commit provides additional context of the changes in Linux:
> https://github.com/torvalds/linux/commit/cefc7ca46235f01d5233e3abd4b79
> 452af01d9e9
>
> Windows 11 (https://www.microsoft.com/software-download/windows11)
> and Windows Server 2022 (https://docs.microsoft.com/en-us/windows-
> hardware/drivers/download-the-wdk)
> include the PRM functionality noted above in addition to PRM direct call and
> PRM runtime updates.
>
> PRM has been tested on IA32, X64, and AARCH64 targets.
>
> 4. Interest from the community and future collaboration
>
> PRM has been presented at several industry conferences:
>
> * OSFC 2020 - "PRM: SMM Goes on a Diet"
> https://cfp.osfc.io/osfc2020/talk/MCJASB/
>
> * OCP Summit 2019 - "Case Study Alternatives for SMM Usage in
> Intel Platforms"
> https://www.youtube.com/watch?v=mu3DRLM1dPA
>
> In addition, Microsoft plans to publish the Windows PRM driver interface and
> a WDF sample driver that uses the interface to the Windows Driver Samples
> GitHub repository (https://github.com/microsoft/Windows-driver-samples).
>
> We believe a PrmPkg in edk2 can increase accessibility to PRM and ease
> collaboration.
>
> PrmPkg
> ------
> PrmPkg contains the common functionality needed to enable PRM on any
> system. It does not contain platform-specific code such as PRM modules (and
> by extension PRM handlers). Other than sample modules, PrmPkg will only
> contain code needed to provide PRM feature functionality as defined in the
> PRM Specification.
>
> PrmPkg is scoped to continue to only contain platform-agnostic functionality
> in the future.

> * Nate DeSimone <nathaniel.l.desimone at intel.com>
