设备树中的内存映射节点未显示在/proc/iomem中 [英] Memory-Maped Node in a Device Tree is not getting shown in /proc/iomem
本文介绍了设备树中的内存映射节点未显示在/proc/iomem中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在基于英特尔FPGA的SoC系统中添加自定义内存映射组件。我已经将定制组件(NVDLA)连接到轻量级AXI桥(HPS到FPGA桥)。设备树文件。

arria10_hps_bridges节点及其子节点NVDLA_IP_0未显示在/proc/iomem中。
是否有人可以查看它并让我知道为什么Linux不能识别arria10_hps_bridges节点。
提前感谢
推荐答案
此问题已解决。通过注释中提到的说明和Ian Abbott的here运行NVDLA_IP_0的KMD驱动程序后，该节点出现在/pro/iomem中。
这篇关于设备树中的内存映射节点未显示在/proc/iomem中的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
