Thanks. So who "owns" this ABI (ie has the authority to change it and should be the end documenting it)? How many projects or bits of software are implementing either end of it? If we decide that QEMU owns the spec we can put the documentation into docs/specs/. > FWIW this is pretty much a direct copy of the m68k semihosting protocol, > which CodeSourcery contributed ages ago to both libgloss and qemu. Yeah, and that seems to be undocumented too :-( I'm not a huge fan of "this is just some random thing that's private to QEMU and libgloss". thanks -- PMM
