TF-A Tech Forum Agenda @ Thr 28th January 2021 16:00-1700 GMT

by Joanna Farley

Hi All, The next TF-A Tech Forum is scheduled for Thu 28th January 2021 16:00 – 17:00 (GMT). Agenda: * TF-A: Automotive Enhance (AE) Architecture Support Requirements Discussion * Presented by Manish Pandy and Manish Badarkhe * A discussion on the needs for the Automotive Enhance (AE) space and how TF-A can support that with CPU and GIC capabilities. The goal is to follow-up the recent email to the TF-A mailing list and try and understand project needs in this space by talking to the project community. 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: 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 on the TF-A mailing list. Join Zoom Meeting https://zoom.us/j/9159704974<https://www.google.com/url?q=https%3A%2F%2Fzoom.us%2Fj%2F9159704974&sa=D&us…> Meeting ID: 915 970 4974 One tap mobile +16465588656,,9159704974# US (New York) +16699009128,,9159704974# US (San Jose) Dial by your location +1 646 558 8656 US (New York) +1 669 900 9128 US (San Jose) 877 853 5247 US Toll-free 888 788 0099 US Toll-free Meeting ID: 915 970 4974 Find your local number: https://zoom.us/u/ad27hc6t7h<https://www.google.com/url?q=https%3A%2F%2Fzoom.us%2Fu%2Fad27hc6t7h&sa=D&us…> Thanks Joanna

Re: [TF-A] Gather GIC changes required for safety critical machines

by Varun Wadekar

<Cc alias> I guess, something went wrong when I clicked "Reply all" the first time. Manish, can you also talk about the tasks that Arm is willing to work on? Then we can ask for volunteers for the remaining ones. I'm sure, NVIDIA will contribute as this topic is close to our heart. -Varun From: Manish Pandey2 <Manish.Pandey2(a)arm.com> Sent: Monday, January 25, 2021 8:05 AM To: Varun Wadekar <vwadekar(a)nvidia.com> Cc: Filipe Rinaldi <Filipe.Rinaldi(a)arm.com>; Robin Randhawa <Robin.Randhawa(a)ARM.com>; Ed Doxat <Ed.Doxat(a)arm.com>; Joanna Farley <joannafarley(a)icloud.com>; Manish Badarkhe <Manish.Badarkhe(a)arm.com>; Olivier Deprez <Olivier.Deprez(a)arm.com>; Matteo Carlini <Matteo.Carlini(a)arm.com>; Doug Richmond <Doug.Richmond(a)arm.com> Subject: Re: Gather GIC changes required for safety critical machines External email: Use caution opening links or attachments ++ Other Arm folks Just realized that Varun has reduced the recipients(guess that was intentional) ________________________________ From: Manish Pandey2 <Manish.Pandey2(a)arm.com<mailto:Manish.Pandey2@arm.com>> Sent: 25 January 2021 10:15 To: Varun Wadekar <vwadekar(a)nvidia.com<mailto:vwadekar@nvidia.com>> Cc: Filipe Rinaldi <Filipe.Rinaldi(a)arm.com<mailto:Filipe.Rinaldi@arm.com>>; Robin Randhawa <Robin.Randhawa(a)ARM.com<mailto:Robin.Randhawa@ARM.com>>; Ed Doxat <Ed.Doxat(a)arm.com<mailto:Ed.Doxat@arm.com>> Subject: Re: Gather GIC changes required for safety critical machines Hi Varun, We are trying to do both, based on interest from community we will prioritize these tasks. The reason why we can't do all the asks (mentioned in the list) ourselves is, currently we do not have "use cases/platforms" to test all the features, so we would rely on wider community to understand the requirements and work together to develop/test those features.

The list captures all the functionalities that are useful and interesting to us. Trying to understand the ask - are you trying to get feedback to allow you to prioritize the feature list? Or are you asking for the community to rate importance of these requirements? I am afraid, if there isn't enough interest the list might be trimmed which would be an absolute shame. -Varun From: TF-A <tf-a-bounces(a)lists.trustedfirmware.org<mailto:tf-a-bounces@lists.trustedfirmware.org>> On Behalf Of Manish Pandey2 via TF-A Sent: Friday, January 22, 2021 8:02 AM To: tf-a(a)lists.trustedfirmware.org<mailto:tf-a@lists.trustedfirmware.org> Cc: Filipe Rinaldi <Filipe.Rinaldi(a)arm.com<mailto:Filipe.Rinaldi@arm.com>>; Robin Randhawa <Robin.Randhawa(a)ARM.com<mailto:Robin.Randhawa@ARM.com>>; Ed Doxat <Ed.Doxat(a)arm.com<mailto:Ed.Doxat@arm.com>> Subject: [TF-A] Gather GIC changes required for safety critical machines External email: Use caution opening links or attachments Hi, GIC600-AE is variant of GIC for safety critical machines, though its TRM is publicly available from quite some time but currently we do not have support in TF-A. Purpose of this email is to kick start discussions around various possible GIC requirements as far as safety critical machines are concerned. We have created following list of requirements based on inputs we got so far, changes are either adding new AE features or enhancements to existing drivers. GIC-600AE feature requirement: - Inject and detect RAS errors using Fault management unit(FMU) - Validating feature parity with GIC600 - Running GIC IP in Dual core Lock-step(DCLS) mode. GIC/RAS driver enhancements: - Read trace and PMU records - Keep RAS error records alive across a reset - Disable GICR frames of fused-off cores - Support for message signalled interrupts - Saving/Restoring additional GIC registers during PM events Feel free to add any additional requirements. If there is enough community interest during the next Tech-forum meeting(28th Jan) we would like to go through these requirements in more detail.

[PATCHv9 0/3] arm-virt: add secure pl061 for reset/power down

by Maxim Uvarov

v9: - cosmetic changes (move if from patch2 to patch3, rename function name and define). v8: - use gpio 0 and 1, align dtb with kernel gpio-restart, gpio-poweroff, change define names, trigger on upper front. (Peter Maydell). v7: - same as v6, but resplit patches: patch 2 no function changes and refactor gpio setup for virt platfrom and patch 3 adds secure gpio. v6: - 64k align gpio memory region (Andrew Jones) - adjusted memory region to map this address in the corresponding atf patch v5: - removed vms flag, added fdt (Andrew Jones) - added patch3 to combine secure and non secure pl061. It has to be more easy to review if this changes are in the separate patch. v4: rework patches accodring to Peter Maydells comments: - split patches on gpio-pwr driver and arm-virt integration. - start secure gpio only from virt-6.0. - rework qemu interface for gpio-pwr to use 2 named gpio. - put secure gpio to secure name space. v3: added missed include qemu/log.h for qemu_log(.. v2: replace printf with qemu_log (Philippe Mathieu-Daudé) This patch works together with ATF patch: https://github.com/muvarov/arm-trusted-firmware/commit/886965bddb0624bdf851… Maxim Uvarov (3): hw: gpio: implement gpio-pwr driver for qemu reset/poweroff arm-virt: refactor gpios creation arm-virt: add secure pl061 for reset/power down hw/arm/Kconfig | 1 + hw/arm/virt.c | 111 ++++++++++++++++++++++++++++++++++-------- hw/gpio/Kconfig | 3 ++ hw/gpio/gpio_pwr.c | 70 ++++++++++++++++++++++++++ hw/gpio/meson.build | 1 + include/hw/arm/virt.h | 2 + 6 files changed, 167 insertions(+), 21 deletions(-) create mode 100644 hw/gpio/gpio_pwr.c -- 2.17.1

by Joanna Farley

Apologies for the late notice I am cancelling this weeks TF-A Tech forum tomorrow as the subject I had hoped to get presented is not ready and I don’t have any alternative for this slot. I will look to have something for the next session on 28th January. Apologies for the late notice. Cancellations of the calendar invite will come from trustedformware.org as I don’t own the invite so it may not appear in your calendars until that is sent out. Thanks Joanna
