HPE gen10 固件

我之前应该答了，IE和SPS都是ME的补充， Intel 芯片中一个独立于CPU和操作系统的微处理器，可以接收带外芯片的信号，然后控制CPLD运行。不同的是各厂商可以对其进行自定义更改开发，特定开发后才会有作用，否则不会运行。

Innovation Engine (IE) is a tiny microcontroller coprocessor integrated within Intel's server chipsets that provides the framework necessary for system designers to create their own highly customized firmware. From an architectural standpoint, IE is very similar to Intel's Management Engine (ME), but is designed as an "open engine", allowing system designers to develop their own differentiating firmware. IE complements ME and are both present starting with the introduction of the Lewisburg chipset.

Intel introduced Innovation Engine (IE) starting with the Lewisburg chipset (i.e., Skylake-SP parts). IE is integrated along with ME into the chipset. Whereas ME is designed specifically for Intel's features, IE is designed specifically for system designers. That is, Intel only provides the hardware to operate IE but unless the system designers develop specific firmware for it, it does not do anything.

Like Intel's ME, IE runs on a 32-bit x86 Quark microcontroller. IE runs cryptographically signed "IE code" only, bound to the system-builder. Unauthenticated code will not load. Unlike ME, IE has additional access to UART. There is also an optional baseboard management controller (BMC) access for system designers that implement IE firmware features that communicates directly with the network.

IE是CPU的ME模块中多出来的需要后续开发的留白。HPE做了后续开发，H3C应该没做过更改。

SPS也是intel的，具体功能没搜到资料。

应该也与CPLD、ME相关，主导上电、带外等功能的。
