软件包 intel-microcode/微码数据文件

我有一台 braswell 处理器,一台英特尔 N3150。根据微码修订指南,应该有一个微码更新:

https://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf

Cherry View (Cherry Trail, Braswell) Intel® Atom® x5-Zxxxx CPU 406C3 01 Production --- --- 00000367

Cherry View (Cherry Trail,Braswell) Intel® Celeron® Processor Jxxxx, Intel® Celeron® Processor N3xxx, Intel® Pentium® Processor J3xxx, Intel® Pentium® Processor N3xxx, Intel® Atom® x5-E8000 Processor 406C4 01 Production --- --- 00000410

我的 CPUID 是 406C3 ... 我不知道为什么它不是 406C4,但两者都有英特尔确认的更新。但如果我查看最新的微码数据文件(2018 年 4 月 25 日),则不包含这些更新:

/microcode-20180425$ iucode_tool -tr -l ./intel-ucode

所以我的问题是,ubuntu 是否可以像制造商一样访问 intel-microcode 软件包的所有更新,或者是否依赖于来自 intel 的微码数据文件?我不知道我的制造商是否会提供 bios 更新。intel 是否有希望在未来提供所有微码更新(在微码修订指南中提到,也在微码数据文件中提到)?为什么英特尔仍然没有这样做?

答案1

intel-microcode 软件包仅发布被英特尔视为可安全进行常规安装的微码,即英特尔在其“Linux 微码发布”文件中分发/已分发的微码。

您可以在 BIOS 修改网站上找到 N3150 的微码更新。使用时请自担风险(如果 BIOS 修改错误,可能会永久损坏主板)。

您可以将额外的微代码添加到 /usr/share/misc/intel-microcode.bin,intel-microcode 将使用它,但由于没有人知道为什么英特尔不认为该微代码“适合广泛分发”,它可能会给您的系统带来严重问题。使用时请自担风险,如果由于固件不兼容而造成任何类型的永久性损坏,请不要抱怨。

并且永远不要再从你购买该主板的供应商那里购买。如果你不用钱包投票,你就没有抱怨的余地……

答案2

使用UBU bios 修改工具。

关联:https://www.win-raid.com/t154f16-Tool-Guide-News-quot-UEFI-BIOS-Updater-quot-UBU.html

但是是的,我已经检查过了!2018 年 4 月 2 日的微码更新未包含在 Linux* 处理器微码数据文件版本:20180425(最新)中,因此,UBU Bios 工具无法提供它!

不适用于:https://github.com/platomav/CPUMicrocodes也....

定期检查这两个链接,如果有的话,他们可以发布新的微代码!
