feat(lfa): update LFA service to support BL31 live activation

2026-06-30T15:43:17+00:00

This patch adds the bulk of the BL31 live activation service framework including the warm reset handler. Signed-off-by: John Powell Change-Id: Id9cbeeddbc023ee2540b88008e6c2502d816ee24

feat(lfa): add relocatable code for BL31 live activation

2026-06-30T14:56:36+00:00

This patch adds the relocatable code functions that are copied out of the main BL31 image during a live activation and updates the holding pen code to have a relocatable variant. Change-Id: I30ba6e118a6b888e0adf4dbd605d15ac0b40bea8 Signed-off-by: John Powell

feat(per-cpu): introduce framework accessors/definers

2025-11-07T16:29:41+00:00

Introduce per-cpu framework definers and accessors for allocation and access of per-cpu objects. The accessors support "per_cpu_cur" variants for access on the calling CPU as well as "per_cpu_by_index" variants for access on any CPU. Additionally, the framework supports NUMA-aware allocation, allowing the per-cpu data to be distributed across different memory nodes. This enables the system to allocate per-cpu data on memory nodes closest to the respective CPU, optimising memory access and performance.

perf(cpufeat): centralise PAuth key saving

2025-04-15T08:06:26+00:00

prepare_el3_entry() is meant to be the one-stop shop for all the context we must fiddle with to enter EL3 proper. However, PAuth is the one exception, happening right after. Absorb it into prepare_el3_entry(), handling the BL1/BL31 difference. This is a good time to also move the key saving into the enable function, also to centralise. With this it becomes apparent that saving keys just before CPU_SUSPEND is redundant as they will be reinitialised when the core wakes up. Note that the key loading, now in save_gp_pmcr_pauth_regs, does not end in an isb. The effects of the key change are not needed until the isb in the caller, so this isb is not needed.

feat(mbedtls): introduce crypto lib heap info struct

2024-12-18T14:48:24+00:00

Add a struct to store information about the memory location of the heap, intended for use with cryptographic libraries such as Mbed-TLS. Change-Id: I42e6bbdbd3a353e01d70fb09b77edeef9498fd98 Signed-off-by: Harrison Mutai

build: remove `MAKE_BUILD_STRINGS` function

2024-04-29T12:47:01+00:00

This function causes the build message to be generated and compiled in two different ways, with one way done inside `build_macros.mk` and the other done inside `windows.mk`, mostly because it's done by generating the C file on the command line. We can instead replace this whole build message generation sequence with a simple standard C compilation command and a normal C file.

feat(spmd): add spmd logical partitions

2023-08-03T14:03:13+00:00

Add header file to help with creation of SPMD logical partitions. Also update linker files to create sections to record SPMD logical partitions declared. This follows the same pattern as the EL3 SPMC's logical partitions. This patch also adds initialization of SPMD logical partitions when the SPMD comes up. ENABLE_SPMD_LP is a build flag that is used to enable support for SPMD logical partitions. Note that the approach chosen is to keep SPMD and SPMC logical partition support separate, as opposed to extend the existing SPMC logical partition support since the code would need to have a number of ifdefs and the interactions with various build options such as SPMC_AT_EL3 needs to be accounted for, which would make code more complicated.

feat(bl): add interface to query TF-A semantic ver

2022-08-02T21:04:23+00:00

Adding interface for stand-alone semantic version of TF-A for exporting to RSS attestation, and potentially other areas as well. Signed-off-by: Lauren Wehrmeister Change-Id: Ib4a2c47aa1e42a3b850185e674c90708a05cda53

feat(spmc/lsp): add logical partition framework

2022-05-04T11:07:33+00:00

Introduce a framework to support running logical partitions alongside the SPMC in EL3 as per the v1.1 FF-A spec. The DECLARE_LOGICAL_PARTITION macro has been added to simplify the process to define a Logical Partition. The partitions themselves are statically allocated with the descriptors placed in RO memory. It is assumed that the MAX_EL3_LP_DESCS_COUNT will be defined by the platform. Change-Id: I1c2523e0ad2d9c5d36aeeef6b8bcb1e80db7c443 Signed-off-by: Marc Bonnici

feat(rme): add ENABLE_RME build option and support for RMM image

2021-10-05T16:49:59+00:00

The changes include: - A new build option (ENABLE_RME) to enable FEAT_RME - New image called RMM. RMM is R-EL2 firmware that manages Realms. When building TF-A, a path to RMM image can be specified using the "RMM" build flag. If RMM image is not provided, TRP is built by default and used as RMM image. - Support for RMM image in fiptool Signed-off-by: Zelalem Aweke Change-Id: I017c23ef02e465a5198baafd665a60858ecd1b25
