Public bug reported: [Impact] S2idle doesn't work on AMD Renoir and Cezanne.
[Fix] Backport AMD PMC driver and pull many new patches let AMDGPU support s2idle. [Test] Suspend the laptop and the system freezes. With the patch applied, suspend works but with some caveats: 1) Keyboard sometimes can't wake up the laptop. 2) Touchpad sometimes can wake up the laptop. 3) RTC can't wake up the laptop. [Where problems could occur] Most changes are limited to logic of suspend/resume, and specific to Renoir GFX. However, there are some refactoring patches may cause unintended results, so AMDGPU may break for sleep/hibernation/runtime suspend on non-Renoir GFXs. ** Affects: linux (Ubuntu) Importance: High Status: Confirmed ** Affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux (Ubuntu Focal) Importance: Undecided Status: Won't Fix ** Affects: linux-oem-5.10 (Ubuntu Focal) Importance: High Status: Confirmed ** Affects: linux (Ubuntu Hirsute) Importance: High Status: Confirmed ** Affects: linux-oem-5.10 (Ubuntu Hirsute) Importance: Undecided Status: Invalid ** Also affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: linux-oem-5.10 (Ubuntu Hirsute) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Confirmed ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Changed in: linux (Ubuntu Focal) Status: New => Won't Fix ** Changed in: linux (Ubuntu Hirsute) Status: New => Confirmed ** Changed in: linux (Ubuntu Hirsute) Importance: Undecided => High ** Changed in: linux-oem-5.10 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-5.10 (Ubuntu Hirsute) Status: New => Invalid ** Changed in: linux-oem-5.10 (Ubuntu Focal) Status: New => Confirmed ** Changed in: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided => High -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1927067 Title: Add s2idle support on AMD Renoir and Cezanne Status in linux package in Ubuntu: Confirmed Status in linux-oem-5.10 package in Ubuntu: Invalid Status in linux source package in Focal: Won't Fix Status in linux-oem-5.10 source package in Focal: Confirmed Status in linux source package in Hirsute: Confirmed Status in linux-oem-5.10 source package in Hirsute: Invalid Bug description: [Impact] S2idle doesn't work on AMD Renoir and Cezanne.
