Hi Shuai Xue:

I notice that we are both handling the same problem, my patchset:
RFC: https://lkml.org/lkml/fancy/2022/12/5/364
RFC PATCH v1: https://lkml.org/lkml/2022/12/7/244
has CC to you

I am glad to see that the community is trying to address the same problems,
I have replied to your RFC version.

Yingwen's proposal in 2022/12/06[1]:
Add Bit 8 in "Common Platform Error Record" -> "Section Descriptor" ->
Flags (which Now, Bit 8 through 31 – Reserved)

Yingwen's proposal makes distinguish synchronous error by CPER report more
easy, however, it's not supported yet.
Looking forward to your reply if there is any progress on the proposal and
your suggestions about my patchset.

Yes, it is not supported yet. So we separated synchronous error handling into
task work based on a similar flag internally.

We submitted the proposal last month after discussed with Tony. But there
is still no progress, I will update it here in time.

Cheers,
Shuai

By the way, if you agree with the proposal, please vote to approve it in UEFI community
with your right on behalf of your organization, then we can make it happen soon. :)


I notice your proposal yesterday, however I have no permission to access this proposal[1]. I already made my firmware colleague aware of your suggestion yesterday. I will make the meaning and background of this work clear to my firmware colleague, I also hope that this work will move forward :)
