* RedfishPkg/Library: RedfishLibAbner Chang2021-03-1116-3/+4493
| | | | | | | | | | | | | | | | | | | | | | | | | | | | EDK2 port of DMTF libredfish project. We clone the necessary files from open source project libredfish (https://github.com/DMTF/ libredfish) tag v1.0.0 and revise it to incorporate with edk2 firmware code base. The reason of cloning the necessary files instead of using extern submodule of libredfish project: libredfish as a C library which is executed under Windows and Linux. It could be binded with other programming languages such as java and python. The library uses curl library as the communication service with Redfish, which is not easy to be abstracted and replaced with EFI specific protocols (e.g. EFI_REST_EX_PROTOCOL or payload encode/decode library) and EFI data types. We had the conversation with DMTF community and they think edk2 is a firmware solution but not the programming language, therefore they rejected to have edk2 as a binding to libredfish. According to above, we decide to clone the necessary files from libredfish modify it to incorporate with edk2.

* UefiCpuPkg/PiSmmCpu: Don't allocate Token for SmmStartupThisApRay Ni2021-03-111-7/+23
| | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3199 When Token points to mSmmStartupThisApToken, this routine is called from SmmStartupThisAp() in non-blocking mode due to PcdCpuSmmBlockStartupThisAp == FALSE. In this case, caller wants to startup AP procedure in non-blocking mode and cannot get the completion status from the Token because there is no way to return the Token to caller from SmmStartupThisAp(). Caller needs to use its specific way to query the completion status. There is no need to allocate a token for such case so the 3 overheads can be avoided: 1. Call AllocateTokenBuffer() when there is no free token. 2. Get a free token from the token buffer. 3. Call ReleaseToken() in APHandler().

* UefiCpuPkg/SmmCpuFeaturesLib: Add Standalone MM supportMichael Kubacki2021-03-089-6/+95
| | | | | | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3218 Adds an INF for StandaloneMmCpuFeaturesLib, which supports building the SmmCpuFeaturesLib code for Standalone MM. Minimal code changes are made to allow reuse of existing code for Standalone MM. The original INF file names are left intact (continue to use SMM terminology) to retain backward compatibility with platforms that use those INFs. Similarly, the pre-existing C file names are unchanged to be consistent with the INF file names. Note that all references in library source files to PiSmm.h have been changed to PiMm.h for consistency.

* UefiCpuPkg/SmmCpuFeaturesLib: Cleanup library constructorsMichael Kubacki2021-03-085-32/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's currently two library instances: 1. SmmCpuFeaturesLib 2. SmmCpuFeaturesLibStm There's two constructor functions: 1. SmmCpuFeaturesLibConstructor() 2. SmmCpuFeaturesLibStmConstructor() SmmCpuFeaturesLibConstructor() is called by SmmCpuFeaturesLibStmConstructor() since the functionality in that function is required by both library instances. The declaration for SmmCpuFeaturesLibConstructor() is embedded in "SmmStm.c" instead of being declared in a header file. Further, that constructor function is called by the STM specific constructor. This change moves the common code to a function called CpuFeaturesLibInitialization() which is declared in an internal library header file "CpuFeaturesLib.h". Each constructor simply calls this function to perform the common functionality. Additionally, SmmCpuFeaturesLibConstructor() is moved from SmmCpuFeaturesLibNoStm.c into a instance-specific file allowing SmmCpuFeaturesLibNoStm.c to contain no STM implementation agnostic to a particular library instance.

* EmbeddedPkg: Only print LibGetTime message about compile time epoch onceRebecca Cran2021-03-081-1/+9
| | | | | | | | | | | | | | | | | | | | The message "LibGetTime: RtcEpochSeconds non volatile variable was not found - Using compilation time epoch." can be printed a very large number of times, causing log files to become excessively large. This is because the RtcEpochSeconds variable only gets set if LibSetTime is called, for example by running 'time 12:00' in the UEFI Shell. Avoid this by setting RtcEpochSeconds to BUILD_EPOCH (EpochSeconds) after printing the message. It's set to a volatile variable so the message will be displayed on future boots and not hidden. Commit 44ae214591e58af468eacb7b873eaa0bc187c4fa reduced the verbosity of the message to DEBUG_VERBOSE. Revert it back to DEBUG_INFO so it's more prominent now that it doesn't get printed so frequently.

On MM model that blocks all non-MMRAM accesses, areas requested through this API will be mapped or unblocked for accessibility inside MM environment. For MM modules that need to access regions outside of MMRAMs, the agents that set up these regions are responsible for invoking this API in order for these memory areas to be accessible from inside MM. Example usages: 1. To enable runtime cache feature for variable service, Variable MM module will need to access the allocated runtime buffer. Thus the agent sets up these buffers, VariableSmmRuntimeDxe, will need to invoke this API to make these regions accessible by Variable MM. 2. For TPM ACPI table to communicate to physical presence handler, the corresponding NVS region has to be accessible from inside MM. Once the NVS region are assigned, it needs to be unblocked thourgh this API.

This issue is a false positive and is not seen with GCC. The Get/Set Memory attributes operation is atomic and therefore an FFA_INTERRUPT or FFA_SUCCESS response is not expected in response to FFA_MSG_SEND_DIRECT_REQ. So the remaining cases that could occur are: - the target sends FFA_MSG_SEND_DIRECT_RESP with a success or failure code. or - FFA_MSG_SEND_DIRECT_REQ transmission failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3235 The library for this header initially resided in StandaloneMmPkg but moved to MdePkg and now this file is a duplicate of the header file in MdePkg. This change removes the header file from StandaloneMmPkg. More details regarding the history of the library transitioning from StandaloneMmPkg to MdePkg are below. The following commit removed the library from StandaloneMmPkg: d6253d2f9a33 ("StandaloneMmPkg: remove redundant StandaloneMmDriverEntryPoint driver", 2019-03-11) The following commits added the library class & instance to MdePkg: 7df4764e6a81a ("MdePkg: introduce standalone MM entry point library class", 2019-01-14) 5866d4992396 ("MdePkg: introduce standalone MM entry point library implementation", 2019-01-14) Signed-off-by: Michael Kubacki <michael.kubacki@microsoft.com> Acked-by: Ard Biesheuvel <ardb@kernel.org> Acked-by: Laszlo Ersek <lersek@redhat.com>
* UefiCpuPkg/MpInitLib: Use XADD to avoid lock acquire/releaseRay Ni2021-02-262-26/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When AP firstly wakes up, MpFuncs.nasm contains below logic to assign an unique ApIndex to each AP according to who comes first: ---ASM--- TestLock: xchg [edi], eax cmp eax, NotVacantFlag jz TestLock mov ecx, esi add ecx, ApIndexLocation inc dword [ecx] mov ebx, [ecx] Releaselock: mov eax, VacantFlag xchg [edi], eax ---ASM END--- "lock inc" cannot be used to increase ApIndex because not only the global ApIndex should be increased, but also the result should be stored to a local general purpose register EBX. This patch learns from the NASM implementation of InternalSyncIncrement() to use "XADD" instruction which can increase the global ApIndex and store the original ApIndex to EBX in one instruction. With this patch, OVMF when running in a 255 threads QEMU spends about one second to wakeup all APs. Original implementation needs more than 10 seconds.

* BaseTools: Align include guards policyPierre Gondois2021-02-262-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | The EDK II C Coding Standards Specification states that: "Names starting with one or two underscores, such as _MACRO_GUARD_FILE_NAME_H_, must not be used. They are reserved for compiler implementation." [1] The Ecc tool currently checks that the include guard end with a trailing underscore. Thus, the check and the error message should both be modified. The new check forces having one sole trailing underscore character, as the example in the specification shows: "FILE_NAME_H_" [1] This would allow to have more consistency.

* MdeModulePkg/VariableStandaloneMm: Set PcdFlashNvStorageVariableBase to PcdIlias Apalodimas2021-02-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | Instead of running StMM in SPM, OP-TEE creates a new secure partition, which emulates SPM and isolates StMM from the rest of the Trusted Applications (TAs). We can then compile StMM as an FD image and run it in OP-TEE. With the addition of a new RPMB driver, we can leverage OP-TEE and store variables to an RPMB device. Since EDK2 upper layers expect byte addressable code, for the RPMB to work, we need to allocate memory and sync it with the hardware on read/writes. Since DynamicPCDs are not supported in that context we can only use PatchablePCDs. So let's switch them to Pcd instead of FixedPcd and accomodate the new driver. While at it, move the rest of the variables under Pcd section, instead of FixedPcd -- this is in line with how the variables are defined in the other Variable modules.
