## Tiling and corner-snapping
Using GNOME, disable all extensions. Install [Tiling Assistant](https://extensions.gnome.org/extension/3733/tiling-assistant/)
Set Windows and Screen Edges gaps to 12px.

## Virtualization

1. Install necessary packages.
`sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq bridge-utils openbsd-netcat ovmf`

2. Prepare the bootloader (GRUB)
```bash
sudo sed -i 's/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor udev.log_priority=3"/GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor amd_iommu=on iommu=pt udev.log_priority=3"/' /etc/default/grub && \
sudo grub-mkconfig -o /boot/grub/grub.cfg
```

3. Configure `libvirtd`

```bash
sudo sed -i 's/#unix_sock_group = "libvirt"/unix_sock_group = "libvirt"/' /etc/libvirt/libvirtd.conf && \
sudo sed -i 's/#unix_sock_rw_perms = "0770"/unix_sock_rw_perms = "0770"/' /etc/libvirt/libvirtd.conf && \
sudo bash -c 'echo "log_filters=\"1:qemu\"" >> /etc/libvirt/libvirtd.conf' && \
sudo bash -c 'echo "log_outputs=\"1:file:/var/log/libvirt/libvirtd.log\"" >> /etc/libvirt/libvirtd.conf' && \
sudo usermod -aG libvirt $USER && \
sudo systemctl enable libvirtd && \
sudo systemctl start libvirtd && \
sudo sed -i 's/#user = "root"/user = "joey"/' /etc/libvirt/qemu.conf && \
sudo sed -i 's/#group = "root"/group = "joey"/' /etc/libvirt/qemu.conf && \
sudo systemctl restart libvirtd
```

4. Dump the GPU vbios.
Run the script to dump the vbios.

5. Patch the GPU vbios with Bless Hex Editor.
Follow [Mutahar's guide](https://youtu.be/BUSrdUoedTo?t=874) (timestamped) for this bit.
Save the patched version as `vbios_patched.rom`. Restrict its permissions with `chmod 660 vbios_patched.rom && sudo chown joey:joey vbios_patched.rom` then copy it to the share folder with `sudo mkdir /usr/share/vbios && sudo cp vbios_patched.rom /usr/share/vbios/vbios.rom`

6. Set up the VM.
Follow page 5 of the [RisingPrism wiki](https://gitlab.com/risingprismtv/single-gpu-passthrough/-/wikis/) for details on configuring the VM. 

7. Reboot to effect the changes we made to the bootloader.
