On the Cell processor, there is a number of little co-processors (SPUs)
that run alongside the main PowerPC core. Userspace can run code on
them, they operate within the user context via their own MMUs. We
provide a facility for them to issue syscalls (via some kind of RPC to
the main core). The "SPU" indication indicates syscalls that can be
called from the SPUs via that mechanism.
Now, the big question is, anybody still using Cell ? :-)
Cheers,
Ben.

Hi Tom,
Sorry this has caused you trouble, using "spu" there is a bit of a hack
and I want to remove it.
See: https://patchwork.ozlabs.org/patch/1025830/
Unfortunately that series clashed with some of Arnd's work and I haven't
got around to rebasing it.

The name "spu" comes from SPU, which are the small cores in the
Playstation 3. The value in the syscall table says whether that syscall
is available to SPU programs ("spu") or blocked ("nospu"). I don't think
you want to support libseccomp on SPUs, so basically you can just ignore
the spu/nospu distinction.
So I'm pretty sure you can just remove all the "spu" lines, and then
replace "nospu" with "common". As I've done below.
I'll try and get my patch above into a branch and into linux-next
somehow, so that you can at least refer to an upstream commit.
cheers

Thanks for the awesome responses, Ben and Michael. I'll definitely
get Paul's input as well, but it sounds reasonable to exclude SPUs
from the newest libseccomp release.
Michael's recommendation to replace "nospu" with common" and ignore
"spu" entirely has allowed ppc and ppc64 to pass all of our internal
checks.
Thanks again!
Tom

Based on this thread, I don't think we need to worry about "spu" at
this point in time. Thanks everyone.
