Re: Linaro-open-discussions Digest, Vol 32, Issue 7

by Joyce Qi

Hi James, We need your help on blow two topics：memory and RAS patch topics Yicong/Kefeng had worked on memory and RAS patch topics for real product to do some optimization based on Arm64，they had some discussion with the maintainer before for the solutions. Now they had finished the work according to Maintainer’s suggestions, just waiting for maintainer’s final approval for upstream. Can you help check internal how to proceed? We can arrange another dedicated meeting to talk about this. Thank you so much for your help, waiting for your good news!

Databases on Arm public discussion

by Leonardo Augusto Guimarães Garcia

Hello everybody, This is just a reminder that we will have a Databases on Arm public meeting this week on Wednesday, 24 May. Please, remember to bring your topics to the discussion. Our main topic lately has been issues with MySQL on Arm, including any configuration changes that would improve performance. Cheers, Leo

Linaro OP-TEE Contribution (LOC) monthly meeting May 23

by Jens Wiklander

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

Databases on Arm

by Leonardo Augusto Guimarães Garcia

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

Re: FYI, Regarding the talk at KVM Forum 2023 in June (CFP 2nd April)

by James Morse

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
