ppc/spapr: implement H_SIGNAL_SYS_RESET
The H_SIGNAL_SYS_RESET hcall allows a guest CPU to raise a system reset
exception on CPUs within the same guest -- all CPUs, all-but-self, or a
specific CPU (including self).
This has not made its way to a PAPR release yet, but we have an hcall
number assigned.
H_SIGNAL_SYS_RESET = 0x380
Syntax:
hcall(uint64 H_SIGNAL_SYS_RESET, int64 target);
Generate a system reset NMI on the threads indicated by target.
Values for target:
-1 = target all online threads including the caller
-2 = target all online threads except for the caller
All other negative values: reserved
Positive values: The thread to be targeted, obtained from the value
of the "ibm,ppc-interrupt-server#s" property of the CPU in the OF
device tree.
Semantics:
- Invalid target: return H_Parameter.
- Otherwise: Generate a system reset NMI on target thread(s),
return H_Success.
