* grub-core/video/video.c (grub_video_edid_checksum): New function. (grub_video_edid_preferred_mode): Likewise. Try EDID followed by the Flat Panel extension, in line with the X.org VESA driver. * grub-core/video/i386/pc/vbe.c (grub_vbe_bios_get_flat_panel_info): New function. (grub_vbe_bios_get_ddc_capabilities): Likewise. (grub_vbe_bios_read_edid): Likewise. (grub_vbe_get_preferred_mode): Likewise. (grub_video_vbe_setup): When the mode is "auto", try to get the preferred mode from VBE, and use the largest mode that is no larger than the preferred mode (some BIOSes expose a preferred mode that is not in their mode list!). If this fails, fall back to 640x480 as a safe conservative choice. (grub_video_vbe_get_edid): New function. (grub_video_vbe_adapter): Add get_edid. * include/grub/video.h (struct grub_vbe_edid_info): New structure. (struct grub_video_adapter): Add get_edid. (grub_video_edid_checksum): Add prototype. (grub_video_edid_preferred_mode): Likewise. * include/grub/i386/pc/vbe.h (struct grub_vbe_flat_panel_info): New structure. * grub-core/commands/videoinfo.c (print_edid): New function. (grub_cmd_videoinfo): Print EDID if available. * util/grub.d/00_header.in (GRUB_GFXMODE): Default to "auto". This is more appropriate on a wider range of platforms than 640x480. * docs/grub.texi (Simple configuration): Update GRUB_GFXMODE documentation. |
