[Qemu-devel] Need help generating instruction traces from the emulator.

[Qemu-devel] Need help generating instruction traces from the emulator.

[Nisarg Ujjainkar]

Hello,

I am using qemu based aosp (emu-master-dev branch of the aosp) to generate
the instruction traces for android os running on the ARM architecture.

I am able to generate the CPU instruction using the qemu invocation
<https://en.m.wikibooks.org/wiki/QEMU/Invocation#Debugging> flags. For the
purpose of my study, I need all the memory requests from all the IPs and so
far I only have the memory requests from the CPU.

Can tell me about how to generate the traces from all other IPs (GPU, GSM
chip etc.). Since memory requests from other IPs account for more than 30%
of all the memory requests from the SoC (Source unconfirmed). Getting
memory requests from these IPs is very crucial for my research.

Thanks and regards
Nisarg Ujjainkar

This isn't supported by QEMU's logging infrastructure.
You might be able to find places to add suitable logging,
but you'd be looking at modifying the source code of the
relevant devices to do that.
