Hi Joyce

Currently nothing.

There has been some activity on CPU HP. Rafael has proposed alternative approach for _STA handling. Seems fine to me (+ I've tested it) but more eyes always good! https://lore.kernel.org/linux-acpi/4562925.LvFx2qVVIh@kreacher/

Hopefully we can get the testing needed (related to device surprise removal as those paths are touched) and slip this in for next merge window. We want this in ASAP so we find out about any broken firmware in the wild.

Not a useful meeting topic though!

There are a few things we are working on that will want discussion but we aren't ready for next week (and need to give warning to get the right other people there!)

Hi Jonathan，all

Do you have any topic to sync next Tuesday？ Since it is Christmas next week，we can put off the meeting after the holiday whenever you want to sync.

Thanks Joyce

Hi all，

Will cancel today’s meeting since the “Regarding non-RFC patch-set of Virtual CPU Hotplug kernel support” can be continually discussed in the LOD mail list.

Hi Jonathan，all，

Hi Joyce,

Two things from me but maybe email is sufficient if we have nothing else on the agenda:

1) [PATCH v5 0/2] Adds additional information to ARM RAS errors https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-rc3-v5-...

Originally one of our patch sets (Ampere currently pushing it), but has been stalled a long time. There is a need for input from Tony Luck at Intel but also probably needs some ARM review to push it forwards.

2) From Salil and I, a general update on vCPU HP seems in order.

For kernel side of things, Russell got the _STA change in last cycle, but then Rafael (ACPI maintainer) backed it out again to replace it with a more general solution (avoiding an esoteric bug) That released things a little and got us past one of the more fundamental aspects.

We have been going in circles somewhat since then and ended up with a solution that looks much more like some early proposals but 'hopefully' having been through the process it will be acceptable.

Rafael has confirmed the basic form of the ACPI patches now seems fine to him but will review in detail over next week or so. Obviously we are tight to the end of the cycle, so this may not quite make it. If it doesn't, should be in a good shape for early in 6.11.

I think there are some missing acks for some of the smaller patches + we need agreement from arm64 arch maintainers to the new arch_register_cpu() call. We'd been so focused on major parts of series minor changes to the gicv3 driver etc haven't picked up the tags they should have.

Thanks due to Rafael for quick feedback over last few weeks and Russell, Miguel, James, Jean-Phillipe, various Huawei folk over time and others who have been involved in this epic saga. Not there yet but maybe the finish line is in sight.

Which will unlock the QEMU side of things.

Jonathan

Thanks Joyce

Hi Jonathan，all,

Hi Joyce

Currently nothing.

There has been some activity on CPU HP. Rafael has proposed alternative approach for _STA handling. Seems fine to me (+ I've tested it) but more eyes always good! https://lore.kernel.org/linux-acpi/4562925.LvFx2qVVIh@kreacher/

Hopefully we can get the testing needed (related to device surprise removal as those paths are touched) and slip this in for next merge window. We want this in ASAP so we find out about any broken firmware in the wild.

Not a useful meeting topic though!

There are a few things we are working on that will want discussion but we aren't ready for next week (and need to give warning to get the right other people there!)

Hi Joyce,

Thanks for the reminder. Yesterday was a holiday in the UK so I only just picked this up.

A few status reports probably make sense but no need for a call.

1) vCPU HP kernel - will rebase in next day or two and send out. The tags for ACPI and (most of) GIC changes came in just too late for last cyc.e If James can take a look great if not really only needs Will or Catalin to look at it from an arch point of view. QEMU in progress - arch agnostic bit has a lot of good review and adoption by other arch. Arch specific version being rebased etc.

2) https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-rc3-v5-... The series: [PATCH v5 0/2] Adds additional information to ARM RAS errors is still in need of review and is blocking a key feature for us (CPU isolation in rasadaemon)

I think we need to make better use of this meeting. I'll try and line up some useful topics for next month. One possible is some numa fixes for CXL memory etc that I'll post an RFC for in the next few days.

Jonathan

Hi Jonathan，all，

Do you have any topic to sync tomorrow

Hi Joyce,

Two things from me but maybe email is sufficient if we have nothing else on the agenda:

1. [PATCH v5 0/2] Adds additional information to ARM RAS errors

https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-r c3-v5-0-850f9bfb97a8@os.amperecomputing.com/#t

Originally one of our patch sets (Ampere currently pushing it), but has been stalled a long time. There is a need for input from Tony Luck at Intel but also probably needs some ARM review to push it forwards.

2. From Salil and I, a general update on vCPU HP seems in order.

For kernel side of things, Russell got the _STA change in last cycle, but then Rafael (ACPI maintainer) backed it out again to replace it with a more general solution (avoiding an esoteric bug) That released things a little and got us past one of the more fundamental aspects.

We have been going in circles somewhat since then and ended up with a solution that looks much more like some early proposals but 'hopefully' having been through the process it will be acceptable.

Rafael has confirmed the basic form of the ACPI patches now seems fine to him but will review in detail over next week or so. Obviously we are tight to the end of the cycle, so this may not quite make it. If it doesn't, should be in a good shape for early in 6.11.

I think there are some missing acks for some of the smaller patches + we need agreement from arm64 arch maintainers to the new arch_register_cpu() call. We'd been so focused on major parts of series minor changes to the gicv3 driver etc haven't picked up the tags they should have.

Thanks due to Rafael for quick feedback over last few weeks and Russell, Miguel, James, Jean-Phillipe, various Huawei folk over time and others who have been involved in this epic saga. Not there yet but maybe the finish line is in sight.

Which will unlock the QEMU side of things.

Jonathan

Hi Joyce

Currently nothing.

There has been some activity on CPU HP. Rafael has proposed alternative approach for _STA handling. Seems fine to me (+ I've tested it) but more eyes always good! https://lore.kernel.org/linux-acpi/4562925.LvFx2qVVIh@kreacher/

Hopefully we can get the testing needed (related to device surprise removal as those paths are touched) and slip this in for next merge window. We want this in ASAP so we find out about any broken firmware in the wild.

Not a useful meeting topic though!

There are a few things we are working on that will want discussion but we aren't ready for next week (and need to give warning to get the right other people there!)

Hi Jonathan，all，

Would like to sync next Tuesday for some topics（CXL memory or others）？

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.

No problem，we can schedule another time when you/James are available.

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.

Cool!

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.

Thanks for the update, maybe we can talk about these topics during next meeting when James comes back? I will cancel next Tuesday’s meeting.

Hi Joyce,

Thanks for the reminder. Yesterday was a holiday in the UK so I only just picked this up.

A few status reports probably make sense but no need for a call.

1. vCPU HP kernel - will rebase in next day or two and send out. The tags for ACPI and (most of) GIC changes came in just

too late for last cyc.e If James can take a look great if not really only needs Will or Catalin to look at it from an arch point of view. QEMU in progress - arch agnostic bit has a lot of good review and adoption by other arch. Arch specific version being rebased etc.

2. https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-rc3-v5-...

The series: [PATCH v5 0/2] Adds additional information to ARM RAS errors is still in need of review and is blocking a key feature for us (CPU isolation in rasadaemon)

I think we need to make better use of this meeting. I'll try and line up some useful topics for next month. One possible is some numa fixes for CXL memory etc that I'll post an RFC for in the next few days.

Hi Jonathan，all，

Do you have any topic to sync tomorrow

Hi Joyce,

Two things from me but maybe email is sufficient if we have nothing else on the agenda:

1. [PATCH v5 0/2] Adds additional information to ARM RAS errors

https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-r c3-v5-0-850f9bfb97a8@os.amperecomputing.com/#t

Originally one of our patch sets (Ampere currently pushing it), but has been stalled a long time. There is a need for input from Tony Luck at Intel but also probably needs some ARM review to push it forwards.

2. From Salil and I, a general update on vCPU HP seems in order.

For kernel side of things, Russell got the _STA change in last cycle, but then Rafael (ACPI maintainer) backed it out again to replace it with a more general solution (avoiding an esoteric bug) That released things a little and got us past one of the more fundamental aspects.

We have been going in circles somewhat since then and ended up with a solution that looks much more like some early proposals but 'hopefully' having been through the process it will be acceptable.

Rafael has confirmed the basic form of the ACPI patches now seems fine to him but will review in detail over next week or so. Obviously we are tight to the end of the cycle, so this may not quite make it. If it doesn't, should be in a good shape for early in 6.11.

I think there are some missing acks for some of the smaller patches + we need agreement from arm64 arch maintainers to the new arch_register_cpu() call. We'd been so focused on major parts of series minor changes to the gicv3 driver etc haven't picked up the tags they should have.

Thanks due to Rafael for quick feedback over last few weeks and Russell, Miguel, James, Jean-Phillipe, various Huawei folk over time and others who have been involved in this epic saga. Not there yet but maybe the finish line is in sight.

Which will unlock the QEMU side of things.

Jonathan

Thanks Joyce

Hi Jonathan，all，

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,

https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-r c3-v5-0-850f9bfb97a8@os.amperecomputing.com/#t

Originally one of our patch sets (Ampere currently pushing it), but has been stalled a long time. There is a need for input from Tony Luck at Intel but also probably needs some ARM review to push it forwards.

2. From Salil and I, a general update on vCPU HP seems in order.

For kernel side of things, Russell got the _STA change in last cycle, but then Rafael (ACPI maintainer) backed it out again to replace it with a more general solution (avoiding an esoteric bug) That released things a little and got us past one of the more fundamental aspects.

We have been going in circles somewhat since then and ended up with a solution that looks much more like some early proposals but 'hopefully' having been through the process it will be acceptable.

Rafael has confirmed the basic form of the ACPI patches now seems fine to him but will review in detail over next week or so. Obviously we are tight to the end of the cycle, so this may not quite make it. If it doesn't, should be in a good shape for early in 6.11.

I think there are some missing acks for some of the smaller patches + we need agreement from arm64 arch maintainers to the new arch_register_cpu() call. We'd been so focused on major parts of series minor changes to the gicv3 driver etc haven't picked up the tags they should have.

Thanks due to Rafael for quick feedback over last few weeks and Russell, Miguel, James, Jean-Phillipe, various Huawei folk over time and others who have been involved in this epic saga. Not there yet but maybe the finish line is in sight.

Which will unlock the QEMU side of things.

Jonathan

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

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.

Hi Joyce,

Thanks for the reminder. Yesterday was a holiday in the UK so I only just picked this up.

A few status reports probably make sense but no need for a call.

1. vCPU HP kernel - will rebase in next day or two and send out. The tags for ACPI and (most of) GIC changes came in just

too late for last cyc.e If James can take a look great if not really only needs Will or Catalin to look at it from an arch point of view. QEMU in progress - arch agnostic bit has a lot of good review and adoption by other arch. Arch specific version being rebased etc.

2. https://lore.kernel.org/all/20240321-b4-arm-ras-error-vendor-info-v5-rc3-v5-...

The series: [PATCH v5 0/2] Adds additional information to ARM RAS errors is still in need of review and is blocking a key feature for us (CPU isolation in rasadaemon)

I think we need to make better use of this meeting. I'll try and line up some useful topics for next month. One possible is some numa fixes for CXL memory etc that I'll post an RFC for in the next few days.

Jonathan

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.

No problem，welcome：）

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.

Hi Joyce,

No problem - its just the way the timezones work! I hadn't reached the the emails about this in my inbox, so joined anyway.

Thanks,

Hi James,

Thanks a lot for joining today’s meeting! Sorry I haven't received Jonathan or other people's feedback to cancel the meeting, and this afternoon I have been visiting customers and forgot to cancel today’s meeting.

I will gather the request earlier next time.
