Is what you have in mind is an ABI that allows SP0 to raise an interrupt in SP1?

Re: [TF-A] Does TF-A support to load and run both TEE and SPM_MM?

by Chen Feng

Hi all, I have a similar but different question here :) Why not the tf-a support both smpd and tspd. Since the vendor's teeos that has not support ff-a interface currently. With armv8.4-sel2, is there a choice to disable scr.eel2 with origin vendor's theeos IDs, and enable scr.eel2 with new ff-a services? It seems to need some tlb maintenance, but it seems work.

Interrupt about ff-a spec

by Chen Feng

Hi, While reading the Arm Firmware Framework for Armv8-A https://developer.arm.com/documentation/den0077/latest I do not find the API that for a sp to request vIRQ, or do I miss something. Is this some private API that is implementing defined FF-A IDs? -- cheers, feng

TF-A Tech Forum Agenda @ Thr 17th December 2020 16:00-1700 GMT: Introduction to the Trusted Services project

by Joanna Farley

Hi All, The next TF-A Tech Forum is scheduled for Thu 17th December 2020 16:00 – 17:00 (GMT). As well as being posted to the TF-A mailing list this has been cross posted to OPTEE mailing list. For OPTEE attendees the Zoom call details are included below. Agenda: * An introduction to the Trusted Services project * Presented by Julian Hall * Summary * The Trusted Services project is a new trustedfirmware.org project that provides a home for security related service components that can run in the different isolated processing environments available on Arm Cortex-A. The project attempts to promote reuse and standardization to enable a consistent set of services to be provided by firmware, independent of which isolation technology is used. If TF-A contributors have anything they wish to present at any future TF-A tech forum please contact me to have that scheduled. Previous sessions, both recording and presentation material can be found on the trustedfirmware.org TF-A Technical meeting webpage: https://www.trustedfirmware.org/meetings/tf-a-technical-forum/ A scheduling tracking page is also available to help track sessions suggested and being prepared: https://developer.trustedfirmware.org/w/tf_a/tf-a-tech-forum-scheduling/ Final decisions on what will be presented will be shared a few days before the next meeting and shared on the TF-A mailing list. This is the last TF-A Tech Forum session until January 2021.

Re: [TF-A] Question about validity period of X509 certificate

by Andrej Butok

Hello Masato Fukumori, To check a "validity period" of a X 509 certificate, you must be sure that your system date & time is set, correct and not changed. Do you have a reliable way to achieve this? Best regards, Andrej Butok From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org> On Behalf Of fukumori.masato--- via TF-A Sent: Thursday, December 10, 2020 2:23 PM To: 'tf-a(a)lists.trustedfirmware.org' <tf-a(a)lists.trustedfirmware.org> Subject: [TF-A] Question about validity period of X509 certificate Hello. I have a question about checking the X 509 certificate with tf-a. My understanding is that tf-a does not check the "validity period" of the X 509 certificate. I 'm not sure why tf-a doesn't check. Does anyone know this background? Best Regards, Masato Fukumori
