Hi, Referring https://github.com/ARM-software/arm-trusted-firmware/blob/master/lib/cpus/a… Software cache maintenance is done till L3 . Referring https://github.com/ARM-software/arm-trusted-firmware/blob/master/lib/cpus/a… for cortex a78 , it is mentioned that HW will do the cache maintenance . is HW cache maintenance done till L3 for cortex a78 case too ? Regards Amit

Deprecating ENABLE_FEAT_MTE build option

by Govindraj Raja

Hi All, Please note build option `ENABLE_FEAT_MTE` is now depcreated[1] and not handled anymore part of TF-A since there is no setting needed in EL3 to enable MTE to be used at EL0. However please note MTE at EL2/EL1 will require setting of ENABLE_FEAT_MTE2 build option[2]. This is also a breaking change for platforms and downstream code that uses MTE at EL2/EL1 without any configuration from TF-A but now SCR_EL3.ATA bit(26) which was set unconditionally prior to this change[3] is now fixed and moved correctly under ENABLE_FEAT_MTE2[3]. Going forward use build option `ENABLE_FEAT_MTE2` to use MTE at EL2/EL1. -- Thanks, Govindraj R [1]: https://review.trustedfirmware.org/q/topic:%22mte_fixes%22 [2]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/27122/19/doc… [3]: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/26891

RAS exceptions TRAP at EL3

by Nagal, Amit

Hi , I am using TF-A tests tests-single-fault.mk to inject RAS errors on AMD Xilinx platform which is cortex a-78 armv8.2 based. With this test , I can see RAS exceptions are getting triggered at EL2 . I want to trap this exception at EL3 and handle RAS errors further using FFH approach. From code , I could see fvp platform using FAULT_INJECTION_SUPPORT=1 , but from documentation it is meant from ARMv8.4 . I am following https://www.trustedfirmware.org/docs/RAS_Tech_Forum.pdf . Another option is RAS_ALLOW_ERR_REC_ACCESS_NS , but in the pdf , for FFH it is mentioned RAS_ALLOW_ERR_REC_ACCESS_NS should be 0. Can I be advised what should be done to trap the RAS exception at EL3 on armv8.2 cortex a78 platform ? Regards Amit

Question about RME-DA in TF-A/TF-RMM/FVP

by Chenxu Wang

Hi all, I find that Arm has considered "device for realms" and purposed RME-DA since last year. This is not only a concept but also includes some SMMU hardware extensions (e.g., Realm Page MMIO and DPT). Unfortunately, I only find few contents related to RME-DA in the latest FVP user guide, and nothing in TF-A/TF-RMM. Thus, can I ask 1. Does current FVP simulate the RME-DA? 2. Will TF-A/TF-RMM supports RME-DA recently? Sincerely, WANG Chenxu

Compatibility support for SPM_MM and SPMD

by baopeng (A)

Hi Olivier Deprez, We use the SPM_MM framework mainly for read/write control of security variables. We do not want to modify the original application code at this time. At the same time we want to add support for the new SPMD framework based code. ________________________________ Hi Baopeng, By "code based on the SPM_MM framework" I assume you refer to a secure service running in a S-EL0 partition based on the MM protocol? If you can share this information, what kind of service is this implementing? RAS handling, secure variables, TPM back end, other? What kind of interface is needed to access the service? asynchronous with interrupts? synchronous with SMC from normal world? Another question is why do you need to collocate the SPMD if the MM implementation is already achieving the scenarios you need? Ideally you'd want to migrate this service to run on top of: * the EL3 FF-A SPMC https://trustedfirmware-a.readthedocs.io/en/latest/components/el3-spmc.html * or if the HW/chipset implements it, the S-EL2 FF-A SPMC https://hafnium.readthedocs.io/en/latest/secure-partition-manager/index.htm… Knowing the kind of S-EL0 service would help narrowing the effort for a migration. FF-A (https://developer.arm.com/documentation/den0077/latest/) is a modern evolution of MM (https://developer.arm.com/documentation/den0060/latest) and any functionality achieved by the MM protocol can be handled by FF-A. For example the MM_COMMUNICATE interface can be easily swapped by the FFA_MSG_SEND_DIRECT_REQ interface. Regards, Olivier. ________________________________ From: baopeng (A) via TF-A tf-a(a)lists.trustedfirmware.org<mailto:tf-a@lists.trustedfirmware.org> Sent: 21 February 2024 07:10 To: tf-a(a)lists.trustedfirmware.org tf-a(a)lists.trustedfirmware.org<mailto:tf-a@lists.trustedfirmware.org> Subject: [TF-A] Re: Request for help Hi Olivier Deprez, We have developed code based on the SPM_MM framework and do not want to reconstruct the code. However, we want to adapt the code to the SPMD framework. What should we do? ________________________________ Hi Baopeng, SPM_MM is the legacy implementation for a secure partition manager relying on the MM protocol. This implementation gets deprecated in favor of FF-A based implementations (what you refer to as SPMD + SPMC). Both implementations aren't compatible and it is discouraged to attempt co-locating both. It may be more palatable and future proof to transition all your SW stack to be compliant to FF-A standard. We may help you better if you tell a bit more about the reason for mixing both implementations in the same build. Regards, Olivier. ________________________________ From: baopeng (A) baopeng1@huawei.commailto:baopeng1@huawei.com Sent: 20 February 2024 02:19 To: tf-a-owner(a)lists.trustedfirmware.org tf-a-owner@lists.trustedfirmware.orgmailto:tf-a-owner@lists.trustedfirmware.org Subject: Request for help Dear Sir/ Madam, we need to support the simultaneous loading of SPMD and SPM_MM due to project reasons. However, we notice that the makefile of SPM_MM of ATF does not support the simultaneous loading of SPMD and SPM_MM by default. I would like to ask what is the main reason for making the current restrictions?
