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

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 flags. For the p

I am trying to understand the block chaining of QEMU. And I have a question about the branch direction of each executed TBs. Suppose the TB#1 has been executed now, and find the next_tb (TB#2). Then we know the direction is TB#1--->TB#2 and store the chain in code cache for speedup the executio

Hello, I'm new to QEMU development and am attempting to write code for a new board and system. I modeled the code after the code in the target-microblaze folder, but removed the dependency on the petalogix board and instead made it require the code from my board. At this point, it can boot and exe
