[Public] Hi, At *least* 9 models of laptops across manufacturers have problems with suspend that are root caused to the firmware not properly implementing an AMD specific codepath, but that did implement a Microsoft specific one properly. To fix the suspend issues on Linux, a number of commits have been worked out over the last few kernel releases. We have eventually landed at we're going to just use the Microsoft codepath in Linux. All the patches to accomplish this are now landed in 6.2-rc1, and also in 6.1.3. Now that have this all working satisfactorily I'd like to bring those fixes into 6.0.y and 5.15.y as well. Here is the series of commits for 6.0.y: 100a57379380 ACPI: x86: s2idle: Move _HID handling for AMD systems into structures fd894f05cf30 ACPI: x86: s2idle: If a new AMD _HID is missing assume Rembrandt a0bc002393d4 ACPI: x86: s2idle: Add module parameter to prefer Microsoft GUID d0f61e89f08d ACPI: x86: s2idle: Add a quirk for ASUS TUF Gaming A17 FA707RE ddeea2c3cb88 ACPI: x86: s2idle: Add a quirk for ASUS ROG Zephyrus G14 888ca9c7955e ACPI: x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7 631b54519e8e ACPI: x86: s2idle: Add a quirk for ASUSTeK COMPUTER INC.
