Public bug reported: [Impact] Several AMD based OEM designs have spurious wakeups occurring from EC events during s2idle. This leads to non-functional wakeup sources or higher power consumption.
[Fix] Prevent setting the GPE for the EC for wakeup source on AMD systems. [Test] Verify s2idle on OEM system. [Where problems could occur] Code is guarded to only run on AMD systems, which are just now getting s2idle support in oem kernel. ** Affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.13 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Assignee: Kai-Heng Feng (kaihengfeng) Status: New ** Affects: linux-oem-5.13 (Ubuntu Focal) Importance: Undecided Assignee: Kai-Heng Feng (kaihengfeng) Status: New ** Also affects: linux-oem-5.13 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.13 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.10 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-5.13 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1934398 Title: Prevent spurious wakeups on amd s2idle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-oem-5.10/+bug/1934398/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
