Change the startup code to fix a memory leak and to allow us to accept load options (=command line options). The call graph changes from entry->efi_main->efi_init, where efi_main is the EFI equivalent of main to entry->efi_main->main, where main is what you'd expect. efi_main now is what efi_init was. The prototype of main follows that of C. The first argument is argc and the second is argv. There is no third argument. Allocation of heap pages is now handled by the EFI library and it now deallocates the pages when main() returns or when exit() is called. This allows us to safely return to the boot manager (or EFI shell) without leaks. EFI applications are responsible to free all memory themselves. Handling of the load options is a bit tricky. There are either no load options, load options in ASCII or load options in Unicode. The EFI library will translate the ASCII options to Unicode options as to simplify user code. Since the load options are passed as a single string (if present) and main() accepts argc and argv, the startup code also has to split the string into words and build the argv vector. Here the trickiness starts. When the loader is started from the EFI shell, argv[0] will automaticly load the program name. In all other cases (ie through the boot manager), this is not the case. Unfortunately, there's no trivial way to check. Hence, a set of conditions is checked to determine if we need to fill in argv[0] ourselves or not. This checking is not perfect. There are known cases where it fails to do the right thing. The logic works for most expected cases, though. This includes the case where no options are given.

Lookup the EFI_FPSWA driver and pass the interface pointer through to the kernel before we call ExitBootServices(). I've typed the definitions in efifpswa.h from the Intel FPSWA manual (urk). 2001-11-19 07:09:47 +00:00			`.if ${MACHINE_ARCH} == "ia64"`
