Subject: [PATCH] platform/x86: thinkpad_acpi: Add missing T14s Gen1 type to s2idle quirk list
Date: Sat, 1 Apr 2023 01:24:47 +0200 [thread overview]
Message-ID: <20230331232447.37204-1-asbachb.kernel@impl.it> (raw)
> Lenovo laptops that contain NVME SSDs across a variety of generations have
> trouble resuming from suspend to idle when the IOMMU translation layer is
> active for the NVME storage device.
>
> This generally manifests as a large resume delay or page faults. These
> delays and page faults occur as a result of a Lenovo BIOS specific SMI
> that runs during the D3->D0 transition on NVME devices.

As Lenovo distributes T14s Gen1 laptops with different product names
a missing one is added by this patch.
Note: Based on lenovo support page there might be some more variants which
are not represented in s2idle quirk list.
