AMD用户只用再忍3年AGESA了

For those that haven't yet watched the AMD openSIL presentation from the OCP Regional Summit in Prague from April, the most interesting takeaway was deserving of its own article... AMD openSIL is planned to eventually replace the well known AGESA and that it will be supported across AMD's entire processor stack -- just not limited to EPYC server processors as some were initially concerned but will support all AMD processors.

Since first learning of AMD openSIL in March for open-source silicon initialization and supporting Coreboot and other firmware solutions, we've been eager to learn more about this new open-source AMD effort.

In mid-April they began detailing their plans for AMD openSIL and initial support for 4th Gen EPYC "Genoa" processors and their reference motherboard platform. With the initial focus on EPYC server platforms, it wasn't initially clear if this would be limited to just AMD server processors, but one of the AMD graphics did make mention of Ryzen:

The good news is that during the OCP presentation in Prague, it was made clear that AMD openSIL will be a replacement to AGESA and in turn supporting their entire future processor spectrum. Raj Kapoor, AMD Fellow and AMD's Chief Firmware Architect, in fact began the AMD openSIL presentation by talking about the challenges they've had with AGESA in adapting it to Coreboot for Chromebook purposes with Ryzen SoCs.

Raj said during his presentation, "AMD openSIL will be scaling to both server and client platforms by the 2026 timeframe." It was very refreshing to hear the entire AMD openSIL expanse and that it's not being limited to just server processors with hyperscaler deployments and Chromebooks on the Ryzen side or so. In being more versatile than AGESA, this is a great open-source system firmware outlook for the future.

With AMD openSIL not expected to be production ready until around 2026, this puts it roughly inline for an AMD Zen 6 or Zen 7 introduction. The proof of concept code for AMD Genoa is expected to come soon. Raj further added during the Q&A at the end of the presentation, "AGESA will be end of life, [AMD] openSIL will replace it" on all products.

But until that 2026 production point, it's not clear yet the extent of any client PoC support. Their initial proof of concept code that will soon be published has been talked about just for 4th Gen EPYC. It's likely much of their early AMD openSIL code will be tailoring to server platforms given the greater likelihood of the hyperscalers and other big players helping to evaluate and test the code on their server platforms rather than catering to random end-users wanting to toy around with AMD openSIL on their desktops.

The presentation also noted that beyond AMD openSIL code being open-source, the openSIL specification will also be open. AMD "invites every silicon vendor" to participate in this open-source system firmware endeavor.

Knowing that AMD openSIL is poised to replace AGESA in the future -- across the entire AMD CPU product stack -- is very exciting as opposed to being some complementary niche effort to AGESA that could be easily discontinued, etc. It will be very interesting to see how AMD's open-source firmware journey plays out and stay tuned to Phoronix to keep reading more about it.

但有个坏消息，这应该指的是下一世代的MSDT平台。

翻译：对于那些还没有观看4月在布拉格举行的OCP地区峰会上AMD openSIL演示的人来说，最有趣的收获值得一提的是它自己的文章。。。AMD openSIL计划最终取代众所周知的AGESA，它将在AMD的整个处理器堆栈中得到支持——只是不限于一些人最初担心的EPYC服务器处理器，而是将支持所有AMD处理器。



自从3月份首次学习AMD openSIL用于开源硅初始化并支持Coreboot和其他固件解决方案以来，我们一直渴望了解更多关于AMD这项新的开源工作的信息。



4月中旬，他们开始详细说明他们对AMD openSIL的计划，以及对第四代EPYC“热那亚”处理器及其参考主板平台的初步支持。由于最初的重点是EPYC服务器平台，最初还不清楚这是否仅限于AMD服务器处理器，但AMD的一款显卡确实提到了Ryzen：



好消息是，在布拉格举行的OCP演示会上，明确表示AMD openSIL将取代AGESA，进而支持其未来的整个处理器频谱。事实上，AMD研究员兼AMD首席固件架构师Raj Kapoor在AMD openSIL演示开始时谈到了他们在AGESA将其应用于Coreboot以实现Ryzen SoC的Chromebook目的方面所面临的挑战。



Raj在演讲中表示，“到2026年，AMD openSIL将扩展到服务器和客户端平台。”听到整个AMD openSIL的扩展，我感到非常耳目一新，而且它不仅仅局限于具有超规模部署的服务器处理器和Ryzen方面的Chromebook，这是对未来开源系统固件的展望。



由于AMD openSIL预计要到2026年左右才能投入生产，这使其大致可以推出AMD Zen 6或Zen 7。AMD热那亚的概念验证代码预计很快就会问世。Raj在演讲结束时的问答中进一步补充道，“AGESA将是生命的终结，[AMD]openSIL将取代它”。



但在2026年生产之前，尚不清楚任何客户端PoC支持的程度。他们即将发布的最初概念验证代码仅针对第四代EPYC进行了讨论。他们早期的AMD openSIL代码很可能会根据服务器平台进行定制，因为超级规模和其他大公司更有可能帮助在其服务器平台上评估和测试代码，而不是迎合那些想在台式机上玩AMD openSIL的随机最终用户。



演示还指出，除了AMD的openSIL代码是开源的之外，openSIL规范也将是开放的。AMD“邀请每一家硅供应商”参与这项开源系统固件的努力。



知道AMD openSIL将在未来取代AGESA——在整个AMD CPU产品堆栈中——这是非常令人兴奋的，而不是作为AGESA的一些补充，可以很容易地停止使用等等。看看AMD的开源固件之旅如何发展，并继续关注Phoronix，继续阅读更多关于它的信息，这将是非常有趣的。

也就是说2026年大概率要换AM6接口了，新平台换新的openSIL取代AGESA

AMD：我自己做不明白固件了所以整个开源固件让厂商给我打工，以后固件有问题可不管我事了啊都是厂商优化不到位

对最终用户来说没啥区别，对主板和固件厂商来说更灵活，主要代码还是来自AMD的

话外的意思，就是   你行你上

开源闭源各有好处，但还是支持开源，虽然用户体验会差一点，但是可折腾性强一点，老设备没了官方支持也可能有社区支持。
