/* Read the payload of an Intel PT packet.
 *
 * Reads the payload of the packet starting at @pos into @packet.
 *
 * For pt_pkt_read_psb(), the @packet parameter is omitted; the function
 * validates that the payload matches the expected PSB pattern.
 *
 * Decoding an unknown packet uses @config's decode callback.  If the callback
 * is NULL, pt_pkt_read_unknown() returns -pte_bad_opc.
 *
 * Beware that the packet opcode is not checked.  The caller is responsible
 * for checking the opcode and calling the correct packet read function.
 *
 * Returns the packet size on success, a negative error code otherwise.
 * Returns -pte_bad_packet if the packet payload is corrupt.
 * Returns -pte_eos if the packet does not fit into the trace buffer.
 * Returns -pte_internal if @packet, @pos, or @config is NULL.
