Public bug reported: [Impact] Process of s3 resume take 7s and it's too long which is over 5s.
[Fix] Reference link_active_reporting field of PCI device to determine whether delay is taken or not. Actual delay would be determined by taking maximum between 100ms and pci device's d3cold delay. [test] With the patch, the total time s3 resume is 3874.298 ms which is smaller than 5s. [Regression Potential] Low. This patch only changes the rules to determine whether delay is taken or not. Reference the right field(link_active_reporting), but not speed of pci device. ** Affects: linux (Ubuntu) Importance: Undecided Status: In Progress ** Affects: linux-oem-osp1 (Ubuntu) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Changed in: linux (Ubuntu) Status: New => In Progress ** Also affects: linux-oem (Ubuntu) Importance: Undecided Status: New ** Package changed: linux-oem (Ubuntu) => linux-oem-osp1 (Ubuntu) ** Changed in: linux-oem-osp1 (Ubuntu) Status: New => In Progress ** Changed in: linux-oem-osp1 (Ubuntu) Assignee: (unassigned) => koba (kobako) -- 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/1876844 Title: Speed up the process of s3 resume Status in linux package in Ubuntu: In Progress Status in linux-oem-osp1 package in Ubuntu: In Progress Bug description: [Impact] Process of s3 resume take 7s and it's too long which is over 5s.
