This series is against tip:efi/core. Patches 1-9 are small cleanups and refactoring of the code in libstub/gop.c. The rest of the patches add the ability to use a command-line option to switch the gop's display mode. The options supported are: video=efifb:mode=n Choose a specific mode number video=efifb:<xres>x<yres>[-(rgb|bgr|<bpp>)] Specify mode by resolution and optionally color depth video=efifb:auto Let the EFI stub choose the highest resolution mode available. The mode-setting additions increase code size of gop.o by about 3k on x86-64 with EFI_MIXED enabled. Arvind Sankar (14): efi/gop: Remove redundant current_fb_base efi/gop: Move check for framebuffer before con_out efi/gop: Get mode information outside the loop efi/gop: Factor out locating the gop into a function efi/gop: Slightly re-arrange logic of find_gop efi/gop: Move variable declarations into loop block efi/gop: Use helper macros for populating lfb_base efi/gop: Use helper macros for find_bits efi/gop: Remove unreachable code from setup_pixel_info efi/gop: Add prototypes for query_mode and set_mode efi/gop: Allow specifying mode number on command line efi/gop: Allow specifying mode by <xres>x<yres> efi/gop: Allow specifying depth as well as resolution efi/gop: Allow automatically choosing the best mode Documentation/fb/efifb.rst | 33 +- arch/x86/include/asm/efi.h | 4 + .../firmware/efi/libstub/efi-stub-helper.c | 3 + drivers/firmware/efi/libstub/efistub.h | 8 +- drivers/firmware/efi/libstub/gop.c | 489 ++++++++++++++---- 5 files changed, 428 insertions(+), 109 deletions(-) -- 2.24.1
