- intel igpu related - remove i915drmfb hacks and use simplefb and libgfxinit enabled fb - coreboot 4.19: add patch to fix https://ticket.coreboot.org/issues/500. fbwhiptail still tears screen if in native 1366x769 though - coreboot 4.19: add patch to enable linux tampoline handle coreboot framebuffer (merged https://review.coreboot.org/c/coreboot/+/76431) - coreboot 4.19: add patch to enable coreboot to apply jpeg voodoo to create bootsplash.jpeg injected in cbfs at build time + CircleCI apt imagemagick - (Thanks Nico Huber @icon again for above patches!) - coreboot configs: adapt VESAFB/LIBGFXINIT to use maximum fb height/width - coreboot configs for iGPU only: CONFIG_LINEAR_FRAMEBUFFER_MAX_HEIGHT CONFIG_LINEAR_FRAMEBUFFER_MAX_WIDTH to native size - coreboot configs for dGPU based on Optional VBIOS injected: VESAFB set to 1280x1024 (maximum possible). Details: coreboot configs: remove CONFIG_LINUX_COMMAND_LINE="drm_kms_helper.drm_leak_fbdev_smem=1 i915.enable_fbc=0" - Those were needed to expose i915drmfb driver prior of efifb working.
