Subject: [edk2-devel] [PATCH v4 0/6] Support to unregister SMI handler in SMI handlers
Date: Tue, 16 Apr 2024 10:41:02 +0800 [thread overview]
Message-ID: <20240416024108.1358-1-zhiguang.liu@intel.com> (raw)
Months ago, I sent patch set to fix potential issues in the usage of SMI handler unregistering SMI handler. Discussion can be found in below
link:
https://edk2.groups.io/g/devel/topic/103925794#114251
The conclusion was to only support SMI handler unregistering itself, and not allow SMI handler unregistering other handlers, because we thought there would be no such usage.
However, recently, I find in some platform, there is kind of usage.
To also support SMI handler unregistering other handlers, this patch set use a totally different design. So I revert the former ones first to make the code more readable.
Thank Laszlo for bring up the initial idea for the new design.
V2&V3:
Code refine based on Ray's comments
V4:
Add NULL pointer check to pass CI
Refine commit message
