Custom TXT: Errorcode 0xC0000481

Hello,

just a shortish question because I am a little baffled right now. I am programming a new MLE to be used with Intel TXT. We want to launch this within a running Linux (64Bit) - this should be perfectly possible afaik. I got most of it working, TXT is working (tboot would successfully boot on previous tests!), but now I get this error whenever I execute GETSEC[SENTER]: 0xC0000481.

The Ultimate Intel® Black Belt Software Developer Summit Experience

Twenty eight Intel® Black Belt Software Developers journeyed to San Francisco for IDF2014 and to attend the sixth annual Black Belt Summit Networking/Dinner Event. As Black Belt Program manager I had the pleasure of greeting them and spending time with them during the week. Here I am driving down to the big city. Even though I live in the Bay Area I am nevertheless thrilled every time I cross this amazing bridge!

    部分英特尔处理器硬件预取器的发布

    本文发布的 MST 设置可用来控制基于以下微架构的英特尔处理器上可用的各种硬件预取器: Nehalem、Westmere、Sandy Bridge、Ivy Bridge、Haswell 和 Broadwell。

    上述处理器支持 4 种硬件预取器预取数据。 其中 2 种预取器与一级高速缓存相关(也称 DCU),2 种预取器与二级高速缓存相关。 在每个内核上都有一个带有 0x1A4 地址的特定型号寄存器 (MSR),它可用于控制这 4 种预取器。 该寄存器中的第 0-3 位可用于启用或禁用这些预取器。 该 MSR 中的其他位予以保留。
