config SOC_INTEL_COMMON_BLOCK_GRAPHICS bool select ROMSTAGE_VGA if MAINBOARD_USE_EARLY_LIBGFXINIT help Intel Processor common Graphics support if SOC_INTEL_COMMON_BLOCK_GRAPHICS config SOC_INTEL_CONFIGURE_DDI_A_4_LANES bool help Selected by platforms that require DDI-A bifurcation setup. config SOC_INTEL_DISABLE_IGD bool "Disable Integrated GFX Controller (0:2:0)" default n select MAINBOARD_NO_FSP_GOP help Selected by mainboard user that need to skip IGD initialization where OS can only use one GPU hence need to disable IGD and don't need to run FSP GOP. config SOC_INTEL_GFX_FRAMEBUFFER_OFFSET hex default 0x0 help PCI config offset 0x18 point to LMEMBAR and need to add GTT size to reach at DSM which is referred here as SOC_INTEL_GFX_MEMBASE_OFFSET. SoC that follow such design would override SOC_INTEL_GFX_FRAMEBUFFER_OFFSET with GTT_SIZE value. On SoC platform where PCI config offset 0x18 points to the GMADR directly can use the default value 0x0 without any override. config SOC_INTEL_GFX_NON_PREFETCHABLE_MMIO bool default n help Ignore BAR0(offset 0x10)'s pre-fetchable attribute to use non-prefetchable MMIO to fix OS display driver failure. endif
