获取Linux中每个设备的内存映射 [英] Getting memory map of every device in linux

问题描述

如何获取Linux识别的所有物理设备的内存映射.我已经看过/proc/iomem和/proc/ioports.但是，我无法找到每个设备的内存映射.关于如何实现这一目标的任何想法?

How do I get memory map of all the physical devices that are recognized by Linux. I have already looked up at /proc/iomem and /proc/ioports. However, I was not able to find a per device memory maps. Any idea on how to achieve this?

推荐答案

据我所知，唯一的通用方法是/proc/iomem.这向您展示了将哪些内存范围分配给谁的内核.

As far as I know the only generic way is /proc/iomem. That shows you the kernels of view of what memory ranges are assigned to who.

如果您想了解更多细节，则需要查看每个单独的驱动程序.

If you want more detail you'll need to look at each individual driver.

您可能会从/proc/vmallocinfo获得更多信息，因为ioremap()使用vmalloc(尽管可能并非在所有体系结构上都如此).

You might get some more information from /proc/vmallocinfo because ioremap() uses vmalloc (though possibly not on all architectures).
