From d4ebeaf475dc1137f489f12ffa4e55d914238662 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Mon, 22 May 2017 13:49:22 +0200 Subject: [PATCH] device/Kconfig: Put gfx init methods into a `choice` Provide all gfx init methods as a Kconfig `choice`. This elimates the option to select native gfx init along with running a Video BIOS. It's been only theoretically useful in one corner case: Hybrid graphics where only one controller is supported by native gfx init. Though I suppose in that case it's fair to assume that one would use SeaBIOS to run the VBIOS. For the case that we want the payload to initialize graphics or no pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the choice. If multiple options are available, the default is chosen as follows: * NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS, * VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS, * NATIVE_VGA_INIT, if we don't add a Video BIOS. As a side effect, libgfxinit is now an independent choice.
