vscode setup

This is my vscode setup for developing Linux on a mac. It uses qemu native on osx to execute the results, hopefully hyp mode will get debugging support soon as this will make things a lot quicker.

Documentation is pretty poor right now, I'll try a fresh install so I can find what I have already forgotten about this setup.

pre-requisites

Homebrew install of libvirt and qemu

• instructions for installing homebrew: https://brew.sh
• this setup based on information here:
  • https://libvirt.org/macos.html

% brew install qemu libvirt
% brew services restart libvirt
% echo 'security_driver = "none"' >> /opt/homebrew/etc/libvirt/qemu.conf
% echo "dynamic_ownership = 0" >> /opt/homebrew/etc/libvirt/qemu.conf
% echo "remember_owner = 0" >> /opt/homebrew/etc/libvirt/qemu.conf

Copy vscode directory to the root of your workspace as .vscode and modify to suite your setup

Setup virtual machines

Once everything is connected make sure you install the VM description: (this should probably be a task)

% virsh -c qemu+tcp://gateway.docker.internal/session define .vscode/DebugKernel-arm64.xml

volume mount points

• I use an images directory in my home dir as /boot, so qemu can access results from make install, but its imperfect as what I really want is the Image file, not the vmlinuz file
• I use volume mounts for the linux workspace, the build directory, and the ccache directory to keep things quick

TODO

• add a non-debug quick mode which using hypervisor mode to execute underlying kernel
• integrate u-root
• integrate perf for kernel tracing
