[RFC PATCH v2 4/5] powerpc/syscalls: Split SPU-ness out of ABI

Michael Ellerman mpe at ellerman.id.au
Thu Jan 17 00:27:13 AEDT 2019


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.

v2: Split the spu information into a separate file rather than a new
column in syscall.tbl.
