Hi Dan,

Trusted Firmware sponsored the OSFC 2025. It was hold in the week of Oct. 7th at Google’s campus . It is the first time that OSFC and UEFI Forum worked together to give a full week of firmware conference (largest firmware event in the history that I can remember).

Now the details of the conference are all available.

One of the topics is very related to Trusted Firmware. I have talked to the presenter, and he is interested to give a presentation for Trusted Firmware. You can contact him at chfernal@microsoft.com

From: Dan Handley via TSC tsc@lists.trustedfirmware.org Date: Thursday, December 4, 2025 at 08:53 To: tsc@lists.trustedfirmware.org tsc@lists.trustedfirmware.org Subject: [TF-TSC] TSC minutes 2025-11-20

Hi all

Apologies for the delay, but here are the minutes from the last TSC:

Present: Dan Handley (Arm) Antonio DeAngelis (Arm) Bharath Subramanian (Arm) Eric Finco (ST) Kangkang Shen (FutureWei) David Brown (Linaro) Julius Werner (Google) Dominik Ermel (Nordic) Michael Thomas (Renesas)

Bharath presented the TF-A roadmap (attached) This is mainly about enablement of the 2023-2024 architecture extensions

Eric: Is Rust SPMC something new for the Rust project? Dan: No, we’re just taking the previous Rust SPMC prototype project and turning it into a library for reuse in RF-A and potentially other projects too.

Bharath: Dan – do you want to say something about TF-RMM? Dan: Just that TF-RMM (and Linux kernel guest) has CCA 1.0 support upstream, but Linux host upstreaming has been delayed a long time. Dan: Due to this and KVM maintainer feedback, we’re planning some significant changes to the CCA roadmap. Dan: This requires some replanning - we’ll give a more comprehensive CCA update in a future session.

KK: I went to OSFC conference KK: It was a good 1 week conference. The presentations are online KK: We are sponsors so I got a ticket! Dan: Any particularly interesting sessions? KK: One from Microsoft about TF enablement but you have to be UEFI member to see it. KK: Also asked Microsoft guy if he would present this at TF. KK: I will send contact details.

Dan: Also, note there will be an update on some important changes at Linaro at the next board meeting. Julius: Is that board meeting the earlier one? Bharath: Yes Julius: Will it be recorded? Bharath: We can ask for that bit at least to be recorded. Will also ask Bill to distribute the slides.

Bharath: There’s a TF budget surplus so we’re asking if there are any suggestions on how to spend this? (no response)
