Getting a memory dump.

[Abhishek Vasisht]

Hi guys,

Trying to write a wrapper to get a memory dump of a process with a virtual address and a range. What function/API should I use for this purpose on the from QEMU (Android-emulator)?

I have used a ton of stuff but somehow I'm unable to dump a large number of pages from the RAM :\ .Tried implementing the `memsave` function from the original QEMU source code, also not working. Is there a better way/API to access the guest android memory from a guest virtual address?

Thanks a lot.

That's not the kind of stuff we actually plan to implement or support. I'm afraid you will have to look at the sources and hack them on your own to do this kind of thing. Especially if you want to isolate the memory of a single guest process (you'll need a way to map a vCPU state to a specific guest process information). You may have better luck implementing a root service in the system image to do that.

 

Thanks a lot.
