[PATCH 2/2] powerpc/syscalls: Split SPU-ness out of ABI

Michael Ellerman mpe at ellerman.id.au
Tue Jun 16 23:56:17 AEST 2020


Using the ABI field to encode whether a syscall is usable by SPU
programs or not is a bit of kludge.

The ABI of the syscall doesn't change depending on the SPU-ness, but
in order to make the syscall generation work we have to pretend that
it does.

It also means we have more duplicated syscall lines than we need to,
and the SPU logic is not well contained, instead all of the syscall
generation targets need to know if they are spu or nospu.

So instead add a separate file which contains the information on which
syscalls are available for SPU programs. It's just a list of syscall
numbers with a single "spu" field. If the field has the value "spu"
then the syscall is available to SPU programs, any other value or no
entry entirely means the syscall is not available to SPU programs.

I'm inclined to put this in next and ask Linus to pull it before rc2, that seems
like the least disruptive way to get this in, unless anyone objects?

cheers
