139 /*
140 * AMD systems from Renoir and Lucienne *require* that the NVME controller
141 * is put into D3 over a Modern Standby / suspend-to-idle cycle.
142 *
143 * This is "typically" accomplished using the `StorageD3Enable`
144 * property in the _DSD that is checked via the `acpi_storage_d3` function
145 * but this property was introduced after many of these systems launched
146 * and most OEM systems don't have it in their BIOS.
147 *
148 * The Microsoft documentation for StorageD3Enable mentioned that Windows has
149 * a hardcoded allowlist for D3 support, which was used for these platforms.
150 *
151 * This allows quirking on Linux in a similar fashion.
