Windows Embedded Compact 2013中支持LPAE（Cortex-A7） [英] LPAE (Cortex-A7) support in Windows Embedded Compact 2013

问题描述

您好，

我的处理器基于带有LPAE（大物理地址扩展）的ARM Cortex-A7 MPCore，其寄存器位于高于32位的区域。

i have processor based on ARM Cortex-A7 MPCore with LPAE (Large Physical Address Extension) and its registers located in area which higher than 32-bits.

Windows Embedded Compact 2013是否支持内核中的大型物理地址扩展？是否可以从WEC2013访问40位地址空间？

Is Windows Embedded Compact 2013 supports Large Physical Address Extension in kernel? Is it possible to access to 40-bit address space from WEC2013?

也许WEC2013支持翻译表描述符中的LPAE？

Maybe WEC2013 supports LPAE in Translation Table descriptor?

推荐答案

我检查了armstart.s文件和KernelStart例程：这里有小型转换表描述符正在使用。因此，Windows Embedded Compact中无法实现LPAE。

I was check armstart.s file and KernelStart routine: Here small translation table descriptor is using. So LPAE is not possible in Windows Embedded Compact.

希望下一代Windows Embedded Compact生成具有长表描述符。

Hope next Windows Embedded Compact generation will be with long table descriptor.
