Re: Linaro-open-discussions_call_on_July 26th 2022

by Salil Mehta

[+] LOD Discussions list, missed this earlier. Sorry, for this duplicate mail. Hi Lorenzo, Wanted to catch up regarding the VCPU Hotplug. Sorry, I was on a sabbatical leave since last year so could not participate in any discussions and have just joined back a week ago and still trying to catch up. Had a brief discussion with Jonathan last week and thanks to him and Shameer for carrying forward the baton in my absence. I was made aware, and forgive me if I have missed from any of the past LOD discussions, there are some changes being done over the original kernel patches of the vCPU Hotplug but largely the approach remains the same as the one in original patches with some new ACPI flag(which is now part of the ACPI spec?) related kernel changes? As such, do you have any update regarding above work and in case this work is already done, is it possible to share the latest git repo so that we can test the qemu changes we have with the new kernel changes. In case this has not been done, I was wondering if we could pitch in and help in completing these kernel changes as well and float for review? Hi Joyce, If we are having meeting tomorrow (or whatever is the next one) can this topic be made part of the discussion?

LOD call notes 26 April.

by Jonathan Cameron

Hi, This is a combination of yangyicong and my notes. If we missed anything please point it out. RMR: - (Shameer) Request to look at Patch 4 as some changes from earlier versions. Warning fix for next version. - Lorenzo will check with Robin. - Need to ask Joerg to pull the series. vCPU HP. - https://gitlab.com/jic23/qemu/-/commits/vcpu-poc-1 - Kernel Patches - hopefully posted soon. Not Lorenzo as not available for a few months. - _MAT needed or not. SPDM - Random discussion of the difficulty of debugging the rather complex exchanges. Nothing worth noting. Scheduler: Yangyicong's slides provide a good summary of the question. - Observed that any topology based estimate is going to be challenging! - Vincent - set migration cost per sched domain level? - Dietmar - workloads weren't clear in original thread. Question of taskhot or new Idle Balance as relevant to workload. Tighter description of what is going on in the benchmarks needed. - Vincent - Uarch + cache etc relevant. - Hesham - potentially user perf counters to get some more info. Takeways 1. Need to figure out the underlying reason of the performance variation of certain benchmark: If it's because of task hotness or newidle_balance(), etc. 2. Effect may related to the micro-arch, cache, and task's states. Also can be tuned according to the cpu numbers and scheduler domain levels. 3. Can be get from some firmware reports, to avoid the long time measurement in booting. 4. May be possible to calibrate during the boot time, but narrow the scope of measured CPUs and test time. This won't take long, but is susceptible to noise from other sources. 5. Hardware counters or profilings help understand what is going on, but unlikely to be consistently available for use in the loop. 6. Maybe make migration cost per sched domain on implementation. Thanks, Jonathan

LOD Call notes: 22 March 2022 - vCPU Hotplug Update

by Jonathan Cameron

Hi All, A quick set of notes on the discussion on vCPU hotplug. Great to have Ed join the discussion. If we are going to have further calls on this topic we may want to move the time to be more friendly for the US. Current status * ACPI spec change via code first route approved. * Kernel patches being reworked / rebased by ARM. Expected to be sent out in 5.19 cycle. * QEMU patches being updated by Huawei. Will do at least some light testing and then push out a public git tree so that others can test - will aim to do this so it aligns with kernel code availability. * Ed (Ampere) gave an update to say they are interested in pushing this forwards ASAP and have customer / OS vendor engagement which will be very useful in moving towards a complete solution, particularly ensuring good test coverage etc. Noted that current QEMU patches may not cover all corner cases, for example live migration of VMs that have vCPUs hotplugged. Might 'just work' but we haven't tested it yet so probably not. Given we didn't really add anything on DOE / SPDM over previous calls, I don't plan to send out anything on that topic this time. Thanks to Joyce for hosting the call. If I noted down anything wrong, or incomplete let the list know. Jonathan

Invitation: Bigtop and OpenEuler @ Tue Mar 29, 2022 10am - 10:50am (CST) (linaro-open-discussions@op-lists.linaro.org)

by guodong.xu＠linaro.org

You have been invited to the following event. Title: Bigtop and OpenEuler Hi, All I would like to start a discussion about adding OpenEuler [1] into the supported platforms of Bigtop [2]. Persons or associations who are interested and would like to cooperate are warmly welcome to join. As this is the first meeting on this, let's limit our discussion in the following two: 1. OpenEuler's current status and acceptance level by the community of Arm Servers. 2. From a technical viewpoint, what is required for adding a new platform into Bigtop's supporting list. PS: [1] OpenEuler: openEuler is an open source, free Linux distribution platform. The platform provides an open community for global developers. OpenEuler is an open source project incubated and operated by the OpenAtom Foundation. https://www.openeuler.org/en/ [2] Bigtop: Bigtop support many Operating Systems, including Debian, Ubuntu, CentOS, Fedora, openSUSE and many others. https://bigtop.apache.org/ Thanks.

LOD Call notes: March 22nd 2022 - IORT RMR

by Lorenzo Pieralisi

Hi all, thanks for hosting this call today, some notes on the IORT RMR discussion: - Patchset requiring a final review from ARM (upcoming) but should be ready to be merged - Handling of IO port access at 0x0 on !x86 to be fixed (caused by UEFI allocating addresses starting at 0x0 for BARs and IORT RMR requiring the OS to preserve the BAR value) in Linux but it does not affect the upstreaming of patches (since the only platform where the issue triggers does not have upstream IORT RMR tables) - ACPICA pull request still not merged but on its way - Targeting v5.19 kernel (probably via ACPI tree to avoid Linux ACPICA dependencies) - Repost of final version at v5.18-rc1 Thank you very much Joyce for hosting the call and for any questions please reach out. Lorenzo
