69 just the instruction pointer, but an SPE sample can have data addresses and latency attributes.
84 However, SPE does not provide any call-graph information, and relies on statistical methods.
123 The SPE interrupt must also be described by the firmware. If the module is loaded and KPTI is
124 disabled (or isn't required to be disabled) but the SPE PMU still doesn't show in
