Ah. Sorry, I'd lost track of the date and only got back from LPC today.
We will want to organize an MPAM discussion shortly - I'll get in touch once I know the material is ready etc and perhaps it makes sense prior to next scheduled meeting.
Welcome，we can reschedule when you are ready！
Jonathan

Hi Jonathan，
Do you need to sync something tomorrow during the LOD meeting this time？
Thanks Joyce

Hi Joyce,
Sorry for lack of reply. Was a holiday in UK yesterday.
There are a couple of topics brewing, bug we obviously didn't give enough notice to talk about them today.
We may want to try to reschedule. I'll let you know if not.

Hi Jonathan，all，
Not sure if you have anything（RAS or others） need to sync this Tuesday？
Thanks Joyce

Hi Jonathan，all，
Do we need a call next Tuesday to talk about the below RAS series topics？
Hi Joyce,
The RAS series is continuing but nothing urgent to pick up this week and most of the relevant people have clashes tomorrow.
On the NUMA handling, Mike has posted patches which look pretty good to me so that one may well be resolved.
So from our side I don't think there is anything urgent to discuss.
Thanks,
Jonathan
Thanks Joyce

Hi Joyce,
Unfortunately I have a clash on Tuesday and I think James is currently on leave (via an autoresponder message).
Let me check if we have urgent issues - perhaps we can schedule a call at a different time.
We are working with Mauro Carvalho Chehab who recently rejoined Huawei and is a long time RAS expert + kernel maintainer to try and unblock the RAS series mentioned below.
For vCPU HP the kernel patches still haven't been picked up, but I can poke the relevant maintainers via email. It needs to go through the ARM64 main kernel tree I think and Will and Catalin have not yet replied.
The NUMA CXL memory topic hit an not particularly amusing issue. Mike Rapoport has decided it's time to finally unify the x86 handling with everyone else's. He's doing the work which is good, but on the downside it stalls ARM support for now and the unification is proving tricky it seems.
