Hi,
what exactly is this structure good for?
declared in src/include/boot/linuxbios_tables.h:
struct lb_uint64 { uint32_t lo; uint32_t hi; };
It is used in the following files:
src/arch/i386/boot/linuxbios_table.c src/arch/ppc/boot/linuxbios_table.c src/boot/elfboot.c
since each machine that can compile LinuxBIOS, ie that has a (cross-)gcc, does have a uint64_t we should use that one.
No, it used to be a uint64_t and that caused problems. For reasons of backwards compatibility we want 32bit alignment not 64bit alignment. x86 only requires 32bit alignment for a unit64_t but x86_64 requires 64bit alignment.
For all new instances I agree.
