Hi Roland,
I tried with your patch applied and got this:
drivers/built-in.o: In function `load_vbios_acpi': nouveau_bios.c:(.text+0xa9cdf): undefined reference to `nouveau_acpi_rom_supported' nouveau_bios.c:(.text+0xa9cf4): undefined reference to `nouveau_acpi_get_bios_chunk' drivers/built-in.o: In function `nouveau_connector_detect_lvds': nouveau_connector.c:(.text+0xb49d4): undefined reference to `nouveau_acpi_edid' drivers/built-in.o: In function `nouveau_init': nouveau_drv.c:(.init.text+0x653e): undefined reference to `nouveau_register_dsm_handler' drivers/built-in.o: In function `nouveau_exit': nouveau_drv.c:(.exit.text+0x19b): undefined reference to `nouveau_unregister_dsm_handler' make: *** [.tmp_vmlinux1] Error 1
When I set CONFIG_DRM_NOUVEAU=m rather than =y, I got this:
ERROR: "nouveau_register_dsm_handler" [drivers/gpu/drm/nouveau/nouveau.ko] undefined! ERROR: "nouveau_acpi_rom_supported" [drivers/gpu/drm/nouveau/nouveau.ko] undefined!
