Hi,
Tomorrow it's time for another LOC monthly meeting. For time and connection
details see the calendar at https://www.trustedfirmware.org/meetings/
We are considering bumping the major version number of OP-TEE to 4 and
removing old and unused or not-so-frequently tested compatibility
code. We'll switch to MbedTLS 3.4 instead of the old 2.x branch.
Any other topics?
Thanks,
Jens

Hi, All
As the Bigtop community now agrees to accept OpenEuler as a new
distribution, let's have this meeting to plan what we can do next.
Time: 10am - 10:50am (China Standard Time - Shanghai)
Date: Wed May 17, 2023
Where: https://linaro-org.zoom.us/j/94115445597
Attached is the meeting details.
Thank you.
Best regards,
Guodong Xu
Hello everybody,
I know that this mailing list has been mainly used for kernel
discussions lately, but we are starting a new Linaro open discussion
series of meetings focused on Databases on Arm and I just would like to
warn everybody that we might use this list for some of the discussions
from that series of meetings as well, as this mailing list has been the
central point for open discussions at Linaro.
Our rationale was that this mailing list has low traffic and that it
will be quite easy to differentiate the topics in the e-mails. I will
also request for anyone sending e-mails related to databases to start
their subject with [databases] so that we can easily identify the
e-mails.
If anyone here thinks that might become a problem, just let me know and
we will arrange a different way for communication.
Cheers,
Leo
Hi Salil,
(replying to an off-list email from Salil...)
You suggested proposing a talk on the hotplug stuff for kvm forum, yes we can co-present
it, but we'll need to discuss it here. Let me know if you plan to submit this today, or I
need to do it. I finish work at roughly 6pm UK time.
For a title I suggest: "Supporting hotplug on architectures that don't".
I had a stab at the abstract before you wrote yours:
vCPU hotplug is used by orchestration managers to pre-create VMs, and scale them correctly
when a workload is deployed. Architecture support for adding CPUs to an existing system is
complex, and not feasible to standardise without hardware.
This talk covers the use-cases, difficulties, and a proposed way of supporting this on
architectures that lack physical CPU hotplug.
Comparing it to what you've written.
I'm not sure the abstract needs any technical details. We can mention the history in the
talk, but I don't think its useful to dwell on it.
We'll need to come up with slides, my suggested outline is something like:
* The x86 history: CPU hotplug being supported before virtualisation.
* Why vCPU hotplug is used for on x86 (kata containers, kubernetes, cloud orchestration)
* Why that ACPI mechanism wouldn't work for arm64: we can't support hotplug virtualisation
without real hardware. (not future proof)
* What the actual requirements are.
* Changes to PSCI and arm64-linux to support all this in a future proof way.
* How physical CPU hotplug would work at the same time
[* Slides on the Qemu details and complexities.]
Something to be aware is of is that arm want a clear split in the presentation between the
kernel side of it, and your Qemu work.
Thanks,
James
