* StandaloneMmPkg: Update code to be more C11 compliant by using __func__Rebecca Cran2023-04-101-11/+11
| | | | | | | | | | | | __FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout StandaloneMmPkg.

| | | | | | | | | | | | | | | | TF-A: TrustedFirmware-A SPM: Secure Partition Manager(MM) In TF-A, the name of this field is sp_shared_buf_size. This field is the size of range for transmit data from TF-A to standaloneMM when SPM enable. SpPcpuSharedBufSize is pass from TF-A while StandaloneMM initialize. So, SpPcpuSharedBufSize should be rename to SpSharedBufSize and this field should no multiply by PayloadBootInfo->NumCpus; Signed-off-by: Ming Huang <huangming@linux.alibaba.com> Reviewed-by: Sami Mujawar <sami.mujawar@arm.com>

* StandaloneMmPkg: Support CLANGPDB buildsMarvin Häuser2021-10-181-1/+8
| | | | | | | | | | | | | Currently, the flag "-fpie" is passed for all builds with a GCC family toolchain, including CLANGPDB. CLANGPDB however does not support this flag as it generates PE/COFF files directly. As the flag is mostly required for ARM-specific self-relocation, drop it for other architectures and document the limitation to enable e.g. X64 CLANGPDB builds of StandaloneMmCore.

* StandaloneMmPkg: generate position independent code for StMM coreArd Biesheuvel2020-06-161-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | The standalone MM core runs in a restricted environment that is set up by a higher privilege level, and which may not allow memory regions to be writable and executable at the same time. This means that making the StMM core self-relocatable requires that all the targets of the relocation fixups are outside of the executable region of the image, given that we cannot remap the executable code writable from the executable code itself without losing those execute permissions. So instead, use the existing toolchain support to ensure that position independent code is used where possible, and that all the remaining relocated quantities are emitted into the data section. (Note that staticallly initialized const pointers will be emitted into the .data.rel.ro section, which gets pulled into the .data section by our linker script) To ensure that we don't pick up any absolute references in executable code inadvertently (e.g., in assembler code), add the '-z text' linker option which will force the build to fail in this case.

* StandaloneMmPkg: Add an AArch64 specific entry point library.Supreeth Venkatesh2018-07-204-0/+859
The Standalone MM environment runs in S-EL0 in AArch64 on ARM Standard Platforms and is initialised during the SEC phase. ARM Trusted firmware in EL3 is responsible for initialising the architectural context for S-EL0 and loading the Standalone MM image. The memory allocated to this image is marked as RO+X. Heap memory is marked as RW+XN. Certain actions have to be completed prior to executing the generic code in the Standalone MM Core module. These are: 1. Memory permission attributes for each section of the Standalone MM Core module need to be changed prior to accessing any RW data. 2. A Hob list has to be created with information that allows the MM environment to initialise and dispatch drivers. Furthermore, this module is responsible for handing over runtime MM events to the Standalone MM CPU driver and returning control to ARM Trusted Firmware upon event completion. Hence it needs to know the CPU driver entry point. This patch implements an entry point module that ARM Trusted Firmware jumps to in S-EL0. It then performs the above actions before calling the Standalone MM Foundation entry point and handling subsequent MM events.
