TF-A Tech Forum - Jul 25th 2024 - Unification of Chain of Trust Descriptors

by Olivier Deprez

Hi, On Jul 25th in the TF-A Tech Forum: Unification of Chain of Trust Descriptors - presented by Xialin Liu Currently, the Chain of Trust is implemented using C data structures built into the firmware or through device tree nodes. Maintaining both formats can lead to maintenance challenges. Therefore, we are standardizing the provision of Chain of Trust descriptors exclusively via the device tree and providing a tool to convert device tree descriptors into C source files. This approach simplifies the process, ensuring consistency and reducing the potential for errors associated with managing multiple formats. Regards, Olivier.

Firmware Partition Filesystem query

by Ghennadi Procopciuc

Greetings everyone, I came across the following paragraph while reading the 'Firmware Partition Filesystem' chapter from EBBR v2.2.0 and I would like to clarify my understanding: Where possible, firmware images and data should be stored in a filesystem. Firmware can be stored either in a dedicated firmware partition, or in certain circumstances in the UEFI System Partition (ESP). Using a filesystem makes it simpler to manage multiple firmware files and makes it possible for a single disk image to contain firmware for multiple platforms. Dedicated firmware partitions should be formatted with a FAT filesystem as defined in UEFI § 13.3 File System Format. Dedicated firmware partitions should use the same /FIRMWARE directory hierarchy. OS tools shall ignore dedicated firmware partitions, and shall not attempt to use a dedicated firmware partition as an ESP Questions: 1. Does the above paragraph mean that, if the device allows, all firmware binaries (TF-A, U-Boot, and some others) must be stored in a dedicated firmware partition formatted with a FAT filesystem and GUID Partition Table (GPT) disk layout? 2. If so, would this also mean that, where possible, the BootROM or a (first stage) bootloader running before TF-A should have GPT and FAT support embedded support to load one of the TF-A stages (BL1/BL2)? Regards, Ghennadi

Proper message for ERRATA_NOT_APPLIES case

by Bollapalli, Maheedhar Sai

Hi, On AMD-Xilinx ZynqMP platform for ERRATA_NOT_APPLIES case; the log appearing on the console is as below: "VERBOSE: BL31: cortex_a53: CPU workaround for erratum 819472was not applied". We checked ZynqMP code and found that the ZynqMP cpu revision was higher than the cpu revision intended in the erratum and hence it was not applicable and not applied. The message seems inappropriate to us as from log message it is not clear why it wasn't applied. Our suggestion is that in the log message instead of "not applied" it should be mentioned as "not applicable" as indicated below to reflect the reason properly. "VERBOSE: BL31: cortex_a53: CPU workaround for erratum 819472 was not applicable". Regards, Maheedhar.

BL2 does find only 2 images

by Labs, Torsten

Hey all, i tried to setup a fip.bin and add 3 images (bl31, bl32 and bl33). ./fiptool --verbose create --soc-fw bl31.bin --nt-fw bl33.bin --tos-fw bl32.bin fip.bin When i check the generated fip.bin with fiptool info it shows me all my three images in the fip.bin EL3 Runtime Firmware BL31: offset=0xB0, size=0x13644, cmdline="--soc-fw" Secure Payload BL32 (Trusted OS): offset=0x136F4, size=0x18D864, cmdline="--tos-fw" Non-Trusted Firmware BL33: offset=0x1A0F58, size=0x9692E, cmdline="--nt-fw" But during bootup the BL2 finds only the image id =3 and image id=5 which is BL32 and BL33. Why he is not finding the bl32? Thanks for youre short help. Regards Torsten

by Olivier Deprez

Hi, This Thursday Jul 11th Kathleen Capella from Arm's TF-A team will present: **Using the SMC Fuzzing Module in TF-A** This presentation will show how you might get started with fuzz testing using the SMC fuzzing module in TF-A. I will demonstrate the basic fuzzer features, how to add SMC calls/test cases and how to make use of the module's integration with tf-a-tests and the TF-A CI. Regards, Olivier.

TF-A Tech Forum - Jul 18th 2024 - NUMA-Aware PER-CPU Framework

by Olivier Deprez

Hi, On Thursday Jul 18th 2024 Rohit Mathew from Arm's Infra solutions team will present: ** NUMA-Aware PER-CPU Framework: Enhancing Latency and Storage Efficiency** With the increasing prevalence of multi-chip platforms, it is crucial for software written for Trusted Firmware-A to be NUMA-aware. The PER-CPU framework addresses this need by distributing the allocation of per-CPU objects across different NUMA nodes. This approach reduces NUMA latency and balances the allocation load, leading to improved performance and efficiency. Regards, Olivier.

Re: Questions about the Fault Handling of GPFs

by Olivier Deprez

Hi Feifan Qian, Trapping GPF to EL3 is permitted by the architecture, however I don't believe TF-A provides such option. In general for TF-A's reference software stacks, a GPF is trapped first at EL2 (hence SCR_EL3.GPF=0). E.g. In a system implementing RME, the RMM (@ R-EL2) traps a GPF occurring in an R-EL1/0 Realm (or R-EL2 itself). Similarly, in the secure world, the SPM (@ S-EL2) traps a GPF occurring in a S-EL1/0 secure partition (or S-EL2 itself). Regards, Olivier. ________________________________ From: 钱非凡 <qianfeifan(a)iie.ac.cn> Sent: 01 July 2024 08:52 To: tf-a-owner(a)lists.trustedfirmware.org <tf-a-owner(a)lists.trustedfirmware.org> Subject: Questions about the Fault Handling of GPFs Dear experts, I have been learning the Fault Handling of the Granule Protection Fault in Arm CCA. Upon studying the Arm Document, I discovered that the GPF bit in the SCR_EL3 register controls whether the fault handling of GPFs occurs in EL3 or not. In addition, I noted that `include/arch/aarch64/arch.h` defines a macro `#define SCR_GPF_BIT (UL(1) << 48)`, yet I could not find any reference to this macro in the source code. I want to know that whether ATF has implemented the fault handling of GPFs or if this is a feature to be expected in the future. If its not, how can I implement this. Any guidance or advice you could provide would be greatly appreciated. Sincerely, Feifan Qian
