Re: Linaro-open-discussions Digest, Vol 32, Issue 7 - Linaro-open-discussions - op-lists.linaro.org

23 May 2023

      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!
Thanks a lot:)
Joyce

Hi Yicong,
Thanks for bring up these topics, yeah, our Open Discussion meeting is on May 23th.
Hi James, Mike,
Can you help involve Arm maintainers like Catalin,Mark,Will and the relative people in if you have?
Is there anything controversial in those series or they are just
following the normal
review cycle on the mailing lists ? I don't think arm64 maintainers
would be willing
to join the discussions unless we are stuck on some specific issues
that can't be
resolved on mailing lists.
Please let me know, thanks.
For the batch TLB flush topic, it is previously discussed how to enable this by
a runtime tunnable to avoid potential impact on small systems with several cores.
Catalin proposal one method and I want to see if there's any other worries. But
for this I think it can be resolved on the mailing list.
For the RAS topic,
Hi Kefeng, more input?
For the RAS patch, the biggest issue is that there is very few feedback
from the maintainers :(

ARM64 MC-Safe Copy,

Mark Rutland give some advises in v4 and all are adressed, Catain give 
us some comments in v8 and all are fixed too in v9. This feature is
pushed out one years ago( in 2022/4/16), so we want to make sure that
could it be picked up for v6.4?
2)Handle synchronous exceptions with proper si_code
Both huawei and alibaba are trying to fix the commit
7f17b4a121d0 ("ACPI: APEI: Kick the memory_failure() queue for 
synchronous errors") which is from James Morse(glad to see James
is Cced), but for now no respone from apei/arm.
We want the two arm64 RAS enhancements to be accpeted, any comments
and feedbacks from maintainer are appreciated
Thanks.

Hi Joyce, Jonathan,
Do we plan an open-discussion for this month? If there is, we'd like to discuss 3 memory related topics which will benefit our platform:

the batched TLB flush support on arm64 to optimize the performance of unmapping and page migration on arm64

https://lore.kernel.org/linux-mm/20230518065934.12877-1-yangyicong@huawei.co...
2) ARM64 RAS enhancement including below content. This is important for our product since we've met some real issues.
  a) ARM64 support Machine Check safe memory copy(ARCH_HAS_COPY_MC)
     https://lore.kernel.org/lkml/20221219120008.3818828-1-tongtiangen@huawei.com...
  b) Handle synchronous exceptions with proper si_code
     https://lore.kernel.org/lkml/20230408091359.31554-1-xueshuai@linux.alibaba.c...
     https://lore.kernel.org/lkml/20221205160043.57465-1-xiexiuqi@huawei.com/
We'd like to discuss the current status of these works, the solution and to see if there's any suggestions and worries.
The topics involve memory and RAS related aspect so please feel free to drag anybody works in this area. We'd like to discuss
this with related arm maintianers like Catalin, Mark, Will or others if possible.
Thanks,
Yicong
