I think the callsites would be clearer if you made the function
return true for "PSCI call handled", false for "not recognised,
give the guest an UNDEF". Code like
if (hvf_handle_psci_call(cpu)) {
stuff;
}
looks like the 'stuff' is for the "psci call handled" case,
which at the moment it isn't.
This function merely follows standard C semantics along the lines of "0
means success, !0 is error". Isn't that what you would usually expect?
No, not really. I expect stuff that returns error codes to return negative integers on
failure. I expect stuff that returns a boolean success/failure to return true on success.
