Public bug reported: [Impact] Connect a type-c2hdmi converter on the machine type-c port, video can't output to the external monitor.
[Fix] The patch is provided by Imre(https://patchwork.freedesktop.org/patch/msgid/[email protected]). Correct the typo during output setup. Fix a typo that led to some MST short pulse event handling issue (the short pulse event was handled for both encoder instances, each having its own state). [Test Case] 1. Connected the WD19SC/WD19TB/type-c2hdmi converter with the TGL platform's Type-C port and connected the external monitor on WD19SC/WD19TB/type-c2hdmi with HDMI/Displayport. 2. Cold boot the TGL platform. 3. Check the monitor can be blinked and the video can output to the monitor. [Where problems could occur] Just correct the typo and have low regression risk. ** 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 Status: New ** Affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Assignee: koba (kobako) Status: In Progress ** 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-1913553 ouagadougou ** Description changed: - [impact] + [Impact] + Connect a type-c2hdmi converter on the machine type-c port, video can't output to the external monitor. + + [Fix] + The patch is provided by Imre(https://patchwork.freedesktop.org/patch/msgid/[email protected]). + + Correct the typo during output setup. + Fix a typo that led to some MST short pulse event handling issue (the + short pulse event was handled for both encoder instances, each having + its own state). + + + [Test Case] + 1.
