hello tf-rmm group, Recently I'm learning ARM CCA.But I have trouble running the latest version TF-RMM.It failed at runtime/ core/ init.c/ in func rmm_arch_init.When try to do write_hcrx_el2 action it paniced.So it looks like the FVP doesn't have the hcrx_el2 register.I'm using the FVP_Base_RevC-2xAEMvA_11.27_19. It's the latest version in the arm's offical website.The tf-rmm-v0.5.0 works fine.So I'm wondering how do you test latest version TF-RMM.It would be appreciated if you could reply. Best, Wang.

Re: TF-A Tech Forum regular call

by Olivier Deprez

+ other MLs ________________________________ From: Olivier Deprez Sent: 30 October 2024 11:41 To: tf-a(a)lists.trustedfirmware.org <tf-a(a)lists.trustedfirmware.org> Subject: TF-A Tech Forum regular call Dear TF-A ML members, As mentioned in https://www.trustedfirmware.org/meetings/tf-a-technical-forum/, trustedfirmware.org hosts regular technical calls on Thursdays. It mentions TF-A although in practise a number of Cortex-A projects beyond TF-A were discussed (refer to prior recordings on this page). Unfortunately this slot hasn't been very active recently. By this email I'm kindly emphasizing this forum is open to the community (and beyond trustedfirmware.org members) and you are welcome to propose topics. Presentations/slides are not strictly necessary, and we can also host informal discussions or session of questions. If you think of a topic, please reach to me and I'll be happy to accommodate. Thanks for your contributions in advance! Regards, Olivier.

RMM 1.0 REL alignment

by Soby Mathew

Hi Everyone, RMM specification 1.0-rel0 has been released and the PDF spec and an HTML diff relative to 1.0-eac5 are available on Arm Developer: https://developer.arm.com/documentation/den0137/1-0rel0/ As a heads up, TF-RMM is aiming to align to this version of the specification in the next weeks. There are incompatibilities in some ABIs for REL0 compared to EAC5 specification. The work in progress RMM patches can be found here : https://review.trustedfirmware.org/q/project:TF-RMM/tf-rmm+branch:topics/rm… and corresponding TFTF patches are here : https://review.trustedfirmware.org/q/project:TF-A/tf-a-tests+branch:topics/… . Suitable kernel branches will be published on this mailing list as they become available. Best Regards Soby Mathew

Re: Does the confidential virtual machine support hot-plug for CPU, memory, and devices？

by Jean-Philippe Brucker

Hi, Please have a look at virtio-mem which provides memory hotplug for VMs. It is available in Linux, QEMU, cloud-hypervisor and libvirt: https://libvirt.org/kbase/memorydevices.html#virtio-mem-model Another reason to use virtio-mem rather than ACPI memory hotplug is to keep complexity out of ACPI tables, in order to simplify remote attestation which requires measuring or verifying the firmware tables. For example running QEMU with the following allows to hotplug 4G of memory to the VM: -m 512M,maxmem=1T -object memory-backend-ram,id=mem0,size=4G -device virtio-mem-pci,id=vm0,memdev=mem0,node=0 Then at runtime QEMU monitor can plug and unplug memory: (qemu) qom-get vm0 size (qemu) qom-set vm0 requested-size 1G (qemu) qom-set vm0 requested-size 0 This works for a Realm VM, with a small change to the Linux guest: https://jpbrucker.net/git/linux/commit/?h=cca/v4-hotplug&id=6b8768385fa464a… (I'm not sure it's correct yet but may be worth adding to the initial guest support.) The host adds memory to the guest with RMI_GRANULE_DELEGATE+RMI_DATA_CREATE_UNKNOWN, and removes it with RMI_DATA_DESTROY+RMI_GRANULE_UNDELEGATE which ensures that the pages are wiped before being returned to the host. Virtual device hotplug works out of the box for a Realm VM. The VM needs to have root ports allowing hotplug (see https://www.libvirt.org/pci-hotplug.html#aarch64-architecture ), and the guest kernel must have PCIe hotplug enabled. For example this adds a root port in QEMU: -device pcie-root-port,chassis=1,id=pcie.1,bus=pcie.0 Then in the monitor add a virtio-net device: (qemu) netdev_add user,id=net1 (qemu) device_add virtio-net-pci,netdev=net1,bus=pcie.1,id=hp0 [ 300.003234] pcieport 0000:00:03.0: pciehp: Slot(0): Button press: will power on in 5 sec ... [ 300.798772] virtio-pci 0000:01:00.0: enabling device (0000 -> 0002) # lspci 01:00.0 Ethernet controller: Red Hat, Inc. Virtio 1.0 network device (rev 01) And remove it: (qemu) device_del hp0 The security model of hotplug is equivalent to regular PCI support in a Realm: the guest should only interact with devices whose driver has been hardened against untrusted hosts, and with devices authenticated via CMA-SPDM. Thanks, Jean

Does the confidential virtual machine support hot-plug for CPU, memory, and devices？

by wuweinan＠huawei.com

Cloud vendors hope that cloud servers have hot-plug capabilities for CPU, memory, and devices. In confidential virtual machine scenarios, the measurement values will change after hot-plug , and rmi_data_create needs to be called to dynamically update the device tree information. Please consult CCA's plan for the hot-plug capability , and under the security model of confidential virtual machines, should the hot-plug capability of confidential virtual machines be supported?

Measuring number of instructions for a workload in realm

by sina ab

Hi all, I am working with FVP (Base RevC AEM) and arm integration solution (https://gitlab.arm.com/arm-reference-solutions/arm-reference-solutions-docs…). I want to measure the overhead of a target ML workload between a realm VM and normal world VM. Both VMs are created by this command: nice -n -20 taskset -c 1 lkvm run --realm -c 1 -m 350 -k /root/VM_image/Image -i /root/VM_image/VM-fs.cpio --irqchip=gicv3 the target workload code and data is envisioned into the VM-fs.cpio. I also use GenericTrace to measure the number of instructions executed by core 1 (taskset -c 1 indicates that the VM process should be only given to core one). I use ToggleMTIPlugin to enable/disable tracing at particular points (at the beginning and end of the target workload inside the VM). What I am experiencing is that the numbers in normal world VM are very stable (271 millions) but, the numbers in the realm VM are very different between different runs of realm VM (from 314 to 463 and even 7671 millions!!!). I do all measurements in the same run of FVP in which I create a NW VM and run the target workload, then I destroy it and create a realm VM, run the target workload and destroy it while I repeat this steps several times and then terminates the FVP. I guess something in between the path from the realm to hypervisor makes the numbers unstable (either RMM or secure monitor). Have you ever seen such a problem and worked around measuring number of instructions for the realm workloads? Thanks, Sina

Firmware-A v2.10 release code freeze notification

by Olivier Deprez

Hi All, The next release of the Firmware-A bundle of projects tagged v2.10 has an expected code freeze date of Nov, 7th 2023. Refer to the Release Cadence section from TF-A documentation (https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/docs/about…). Closing out the release takes around 6-10 working days after the code freeze. Preparations tasks for v2.10 release should start in coming month. We want to ensure that planned feature patches for the release are submitted in good time for the review process to conclude. As a kind recommendation and a matter of sharing CI resources, please launch CI jobs with care e.g.: -For simple platform, docs changes, or one liners, use Allow-CI+1 label (no need for a full Allow-CI+2 run). -For large patch stacks use Allow-CI+2 at top of the patch stack (and if required few individual Allow+CI+1 in the middle of the patch stack). -Carefully analyze results and fix the change if required, before launching new jobs on the same change. -If after issuing a Allow-CI+1 or Allow-CI+2 label a Build start notice is not added as a gerrit comment on the patch right away please be patient as under heavy load CI jobs can be queued and in extreme conditions it can be over an hour before the Build start notice is issued. Issuing another Allow-CI+1 or Allow-CI+2 label will just result in an additional job being queued. Thanks & Regards, Olivier.
