---------------------------------------- Bug #507: Windows GPU driver fails to load on AMD based google/guybrush, google/skyrim boards https://ticket.coreboot.org/issues/507
* Author: Matt DeVillier * Status: New * Priority: Normal * Target version: none * Start date: 2023-08-30 * Affected versions: 4.21, 4.15, 4.16, 4.17, 4.18, 4.19, master * Affected hardware: google/guybrush, google/skyrim ---------------------------------------- The Windows GPU drivers on AMD Cezanne and Mendocino platform ChromeOS devices (google guybrush and skyrim boards respectively) fail to load due to the PSP boot mode being `Development` vs `Production.` On these platforms, the PSP only boots in `Production` mode when ChromeOS verified boot mode is active.
Possible solutions include having the PSP boot in `Production` mode when vboot is not used at all, when CONFIG_CHROMEOS is not set, or (always) when PSP signed verstage is used. Any of these require changes to the PSP firmware from AMD.
