Hi, Stewards and All:
So far, there are still three patch sets to be requested to catch this stable tag. They are bug fixes, and pass code review in soft feature freeze phase. Have you any comments for them? 1. Fix two issue in ArmGicLib (https://edk2.groups.io/g/devel/message/72175) 2. Fix CET shadow stack token busy bit clear issue (https://edk2.groups.io/g/devel/message/71864) [Liming] this version uses DB for the instruction. BZ https://bugzilla.tianocore.org/show_bug.cgi?id=3227 is create for future enhancement. 3. Use XADD to avoid lock acquire/release (https://edk2.groups.io/g/devel/message/71516) Thanks Liming 发件人: bounce+27952+71922+4905953+8761045@groups.io <bounce+27952+71922+4905953+8761045@groups.io> 代表 gaoliming 发送时间: 2021年2月22日 16:23 收件人: devel@edk2.groups.io; announce@edk2.groups.io 抄送: 'Andrew Fish' <afish@...>; 'Laszlo Ersek' <lersek@...>; leif@...; 'Michael D Kinney' <michael.d.kinney@...>; 'Soumya Guptha' <soumya.k.guptha@...> 主题: [edk2-devel] Soft Feature Freeze starts now for edk2-stable202102 Hi, all We will enter into Soft Feature Freeze phase. In this phase, the feature under review will not be allowed to be merged. The feature passed review can still be merged. The patch review can continue without break in edk2 community. If the patch is sent before Soft Feature Freeze, and plans to catch this stable tag, the patch contributor need reply to his patch and notify edk2 community. If the patch is sent after Soft Feature Freeze, and plans to catch this stable tag, please add edk2-stable202102 key words in the patch title and BZ, so the community know this patch target and give the feedback. Below is edk2-stable202102 tag planning https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Release-Plannin g Proposed Schedule Date (00:00:00 UTC-8) Description 2020-11-27 Beginning of development 2021-02-15 Feature Planning Freeze 2021-02-22 Soft Feature Freeze 2021-03-01 Hard Feature Freeze 2021-03-05 Release Thanks Liming |

Hi Liming,

Without that patch set, there is no misbehavior, things are just slower. The bugfixes can be merged of course; I wouldn't merge the 3rd series however. ... I can see Ray pushed the first patch of the third series: <https://edk2.groups.io/g/devel/message/72249> I disagree with that. Here's an excerpt from the commit message: With this patch, OVMF when running in a 255 threads QEMU spends about one second to wakeup all APs. Original implementation needs more than 10 seconds. I wouldn't call the pre-patch behavior a bug. And the review for "[PATCH v3 1/4] UefiCpuPkg/MpInitLib: Use XADD to avoid lock acquire/release" only arrived (from Mike) after the SFF, so I don't think it should have been pushed. On the other hand, I also won't ask for a revert. Thanks Laszlo
