** Description changed: [ Impact ] To support PMF driver on new AMD silicon, ID AMDI0112 needs to be added into the PMD driver. - [ Fix ] - Cherry-pick the following patch: + Backport the following patch: 1. [PATCH] platform/x86/amd/pmf: Add AMDI0112 ACPI ID[1] - [ Test Plan ] Boot the kernel with the said patch. The PMF driver should bind. - [ Where problems could occur ] Unless there is existing hardware using this ID already (which likely would be an BIOS issue), this is new hardware enablement, so nothing earlier to regress from. + Although it's just adding an ID, this patch won't apply on 7.0-oem, + because it depends on the code context from [2] and [3], which are PMF + support for even newer silicon. It'll take another 2 patch series (12 + patches) to make this patch apply cleanly and PMF for this ID doesn't + need those patches to work. This ID is added at this point of time as an + afterthought for older silicon.
