From 4b34cca55588696c114d44524d1f088eba826f48 Mon Sep 17 00:00:00 2001 From: Youness Alaoui Date: Wed, 23 May 2018 16:47:17 -0400 Subject: [PATCH] Add VBT file to coreboot image. Adding the VBT file makes it available through some ACPI memory area and apparently the VBT contains the information needed by the i915 driver in order to figure out how to control the screen's backlight. Without the VBT, we can't control the screen backlight with Fn-F5/Fn-F6 anymore. --- config/coreboot-librem13v2.config | 3 ++- config/coreboot-librem15v3.config | 3 ++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/config/coreboot-librem13v2.config b/config/coreboot-librem13v2.config index ec31c9a7..74c4a565 100644 --- a/config/coreboot-librem13v2.config +++ b/config/coreboot-librem13v2.config @@ -512,7 +512,8 @@ CONFIG_PCIEXP_PLUGIN_SUPPORT=y # CONFIG_EARLY_PCI_BRIDGE is not set CONFIG_SUBSYSTEM_VENDOR_ID=0x0000 CONFIG_SUBSYSTEM_DEVICE_ID=0x0000 -# CONFIG_INTEL_GMA_ADD_VBT_DATA_FILE is not set +CONFIG_INTEL_GMA_ADD_VBT_DATA_FILE=y +CONFIG_INTEL_GMA_VBT_FILE="../../blobs/librem_skl/vbt.bin" # CONFIG_SOFTWARE_I2C is not set # diff --git a/config/coreboot-librem15v3.config b/config/coreboot-librem15v3.config index 95a32004..7d6f16da 100644 --- a/config/coreboot-librem15v3.config +++ b/config/coreboot-librem15v3.config @@ -512,7 +512,8 @@ CONFIG_PCIEXP_PLUGIN_SUPPORT=y # CONFIG_EARLY_PCI_BRIDGE is not set CONFIG_SUBSYSTEM_VENDOR_ID=0x0000 CONFIG_SUBSYSTEM_DEVICE_ID=0x0000 -# CONFIG_INTEL_GMA_ADD_VBT_DATA_FILE is not set +CONFIG_INTEL_GMA_ADD_VBT_DATA_FILE=y +CONFIG_INTEL_GMA_VBT_FILE="../../blobs/librem_skl/vbt.bin" # CONFIG_SOFTWARE_I2C is not set #
