Currently this is not supported until v5.4-rc1. [Fix] Commit 3cdb9446a117 "thunderbolt: Add support for Intel Ice Lake" along with all the prerequisites should be backported to enable thunderbolt. [Test Case] Tested on two Dell XPS platforms with ICL-U and thunderbolt support. [Regression Risk] Medium. While v5.4 is still under development and there is already an known issue about suspend/resume on ICL platforms with thunderbolt enabled, it is definitely going to have follow-ups for this backport, as well as more regression tests on previous systems before landed. ========= original bug description ========= v5.4 has commits to fix Thunderbolt support for ICL ce19f91eae43e39 thunderbolt: Correct path indices for PCIe tunnel f437c24bf694b02 thunderbolt: Move NVM upgrade support flag to struct icm 943795219d3cb9f thunderbolt: Use 32-bit writes when writing ring producer/consumer d94dcbb10183f3b thunderbolt: Do not fail adding switch if some port is not implemented 58f414fa435cf72 thunderbolt: Hide switch attributes that are not set 3f415e5ee18b009 thunderbolt: Expose active parts of NVM even if upgrade is not supported 3cdb9446a117d5d thunderbolt: Add support for Intel Ice Lake dfda204198848b4 ACPI / property: Add two new Thunderbolt property GUIDs to the list To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1844680/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
