Subject: [PATCH 1/1] Add runtime option: etc/only-load-option-roms (load, but
don't run)
From anecdotal reports, sometimes it is useful; I've heard of instances where
certain Nvidia graphics cards can, if using the nouveau driver on a GNU+Linux
system, be used without running any option ROM, but where the option ROM has
certain data tables in it that the driver can use.
If set to 1, this will disable *all* option ROM loading, even SeaVGABIOS. 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.
