Public bug reported: [Impact] On CML-R, after S3, No screen show on all three connector(3*DP).
[Fix] The patch is got from https://patchwork.freedesktop.org/patch/416162/. For Legacy S3 suspend/resume GEN9 BC needs to enable and setup TGP PCH. [Test Case] 1. Connected the monitor on one of 3*DP on CML-R. 2. Suspend&resume the machine. 3. Check the monitor can output something. [Where problems could occur] Just Enable the hpd detection in IRQ installer and during suspend&resume. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux (Ubuntu Groovy) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux-oem-5.10 (Ubuntu Groovy) Importance: Undecided Status: New ** Affects: linux (Ubuntu Hirsute) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** Affects: linux-oem-5.10 (Ubuntu Hirsute) Importance: Undecided Status: New ** Tags: oem-priority originate-from-1912745 somerville ** Also affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux (Ubuntu Groovy) Importance: Undecided Status: New ** Also affects: linux-oem-5.10 (Ubuntu Groovy) 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 Focal) Assignee: (unassigned) => koba (kobako) ** Changed in: linux (Ubuntu Groovy) Assignee: (unassigned) => koba (kobako) ** Changed in: linux-oem-5.10 (Ubuntu Focal) Assignee: (unassigned) => koba (kobako) ** Changed in: linux (Ubuntu Focal) Status: New => In Progress ** Changed in: linux (Ubuntu Hirsute) Assignee: (unassigned) => koba (kobako) ** Changed in: linux (Ubuntu Groovy) Status: New => In Progress ** Changed in: linux (Ubuntu Hirsute) Status: New => In Progress ** Changed in: linux-oem-5.10 (Ubuntu Focal) Status: New => In Progress ** Tags added: oem-priority originate-from-1912745 somerville ** Description changed: [Impact] On CML-R, after S3, No screen show on all three connector(3*DP).
