./configure --target-list=<targets> --enable-debug --enable-plugins --prefix=<qemu_install_dir> --disable-werror 
make -j$(nproc)
make install

• change the prefix directory to where you want to install. All parts with <> should be replaced.

• on target-list you should only put the necessary targets for faster compile times. The ones ending with linux-user are the ones for user mode and softmmu are the full system ones.To get a complete list you can execute ./configure --help. For example, the ones I'm interested in it's riscv64-linux-user,riscv64-softmmu.

• you will possibly need to debug QEMU so you should keep the --enable-debug flag, but if you want more performance you should recompile without this flag.

To execute

<qemu_install_dir>/bin/qemu-riscv64 -plugin <qemu_source_dir>/contrib/plugins/lib<the_name_of_your_plugin>.so,<plugin_options> -D <plugin_output_filename> -d plugin <binary>

• -plugin is for enabling a plugin
• -D is for choosing a file to put all the debugging information
• -d plugin is for only output the logs from the plugins

you can find more information about QEMU in it's documentation and more info of the TCG plugins in here.

I obtained the QEMU dependencies from the test/docker/dockerfile directory in the QEMU source.
