The best approach is going to be to see whether we can reduce the uses of efi_setup and the associated special code. Once we've completed that exercise, we can think about the best name for this variable. > For building ACPI tables we need do it in kernel instead of kexec-tools > because of kexec_file_load for secure boot case so we still need a conditional > code path for kexec.. Note that it may not be necessary to build any ACPI tables at all, provided that things like acpi_get_table() fail gracefully for kexec. I'm assuming that's the problem that you discovered when writing this patch. And yes, I don't expect you can build the ACPI table from userspace, but it should at least be possible to do it in setup_boot_parameters() or so when you setup the EFI table pointers (efi.config_tables), etc. I think that would be a natural home for this feature. > Also I'm not sure how to rebuild ACPI tables, it is easy or hard.
