It -also affects CSM. In practise, the only time someone would ever use this is if -they were using a graphics card in the above scenario. Such a use-case is -incredibly rare. - -If set to 0, the normal behaviour can be observed (load, and execute). The -run time option etc/pci-optionrom-exec will still be in effect. - -Signed-off-by: Leah Rowe <leah@libreboot.org> ---- - src/optionroms.c | 6 +++++- - 1 file changed, 5 insertions(+), 1 deletion(-) - -diff --git a/src/optionroms.c b/src/optionroms.c -index e906ab9..db5e893 100644 ---- a/src/optionroms.c -+++ b/src/optionroms.c -@@ -23,7 +23,7 @@ - #include "util.h" // get_pnp_offset - #include "tcgbios.h" // tpm_* - --static int EnforceChecksum, S3ResumeVga, RunPCIroms; -+static int EnforceChecksum, S3ResumeVga, RunPCIroms, OnlyLoadOptionRoms; - - - /**************************************************************** -@@ -34,6 +34,9 @@ static int EnforceChecksum, S3ResumeVga, RunPCIroms; - static void - __callrom(struct rom_header *rom, u16 offset, u16 bdf) - { -+ if (OnlyLoadOptionRoms) -+ return; -+ - u16 seg = FLATPTR_TO_SEG(rom); - dprintf(1, "Running option rom at %04x:%04x\n", seg, offset); - -@@ -461,6 +464,7 @@ vgarom_setup(void) - EnforceChecksum = romfile_loadint("etc/optionroms-checksum", 1); - S3ResumeVga = romfile_loadint("etc/s3-resume-vga-init", CONFIG_QEMU); - RunPCIroms = romfile_loadint("etc/pci-optionrom-exec", 2); -+ OnlyLoadOptionRoms = romfile_loadint("etc/only-load-option-roms", 0); - ScreenAndDebug = romfile_loadint("etc/screen-and-debug", 1); - - // Clear option rom memory --- -2.25.1 - |
