 The image's userland contains a complete (OpenRC-based) Gentoo system (including a full Portage tree) - so you can run `emerge` operations immediately - and has been pre-populated with a reasonable package set (Xfce v4.12, LibreOffice v6.3.5.2, Firefox Quantum v73.0.1, Chromium v82.0.4068.4, Thunderbird v68.5.0, VLC v3.0.8, Kodi v18.6, GIMP v2.10.14 etc.) so that you can get productive *without* having to compile anything first! Unless you *want* to, of course; this being Gentoo, GCC v9.2.0-r4, Clang v9.0.1, IcedTea v3.15.0 (OpenJDK 8), Go v1.14, Rust v1.41.1 and various versions of Python are of course bundled also ^-^ As of version 1.2.0 of the image, all userland software has been built under Gentoo's 17.0 profile, and, as of version 1.5.0 of the image, **the new RPi4 Model B is also supported** (and to reflect this, the project itself has been renamed, from `gentoo-on-rpi3-64bit` to `gentoo-on-rpi-64bit` ^-^).
 
-The kernel and userland are both 64-bit (`arm64`/`aarch64`), and support for the Pi's [VC4](https://wiki.gentoo.org/wiki/Raspberry_Pi_VC4) GPU (VC6 on the Pi4) has been included (using [`vc4-fkms-v3d`](https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=159853) / Mesa), so rendering performance is reasonable (e.g., `glxgears` between 400 and 1200fps, depending on load and system type; real-time video playback). The Pi's onboard Ethernet, WiFi (dual-band on the RPi3 B+ / Pi4 B) and Bluetooth adaptors are supported, as is the official 7" [touchscreen](#touchscreen) (if you have one). Sound works too, both via HDMI (given an appropriate display), and the onboard headphone jack. As of version 1.1.0 of the image, a [weekly-autobuild binhost](#binhost), custom [Gentoo profile](#profile), and [binary kernel package](#binary_kp) have been provided, making it relatively painless to keep your system up-to-date (and, because of this, [`genup`](https://github.com/sakaki-/genup) has been configured to run [automatically once per week](#weekly_update), by default). As of version 1.4.0 of the image, access to the RPi3's hardware video codecs (and camera module, if you have one) [is supported](#v4l2) too, via the V4L2 framework, and, as of version 1.5.0, these features are available on the RPi4 also. Additionally, on the RPi4, the use of dual monitors is supported (but not required) as of version 1.5.0 (as is accelerated graphics, via V3D / Mesa). And, there is no 3GiB 'memory ceiling' anymore: if you are fortunate enough to own a 4GiB Pi4, all 4GiB of that RAM is usable. Finally, as of 1.5.2, [64-bit MMAL userland](#mmal) is supported (and used by bundled tools like `raspivid`), as is automated update of the RPi4's onboard EEPROM firmware.

 * As of version 1.2.2 of the image, you can efficiently run additional guest operating systems on your 64-bit Gentoo RPi3/4, using QEMU virtualization with KVM acceleration (much as you might use, say, VirtualBox on a PC). For further details, please see my wiki tutorial [here](https://github.com/sakaki-/gentoo-on-rpi-64bit/wiki/Run-Another-OS-on-your-RPi-as-a-Virtualized-QEMU-Guest-under-KVM). If you like, you can run a GUI, even a full desktop, on your guest OS, as further detailed [here](https://github.com/sakaki-/gentoo-on-rpi-64bit/wiki/Adding-a-GUI-to-your-QEMU-KVM-Guest-OS). Sample screenshot (with an Ubuntu 18.04 LTS guest):

-  <br>Notice how the guest and host OSes in the above are running different *kernels* - it's not just a `chroot`. On the higher-memory (2 and 4GiB) RPi4 models, running a guest OS using KVM becomes quite a realistic proposition.

 * If you'd like to remotely access your RPi3/4's desktop from another machine (whether a Linux PC, Windows PC, Mac or even another RPi!), you can do so easily, by using [VNC](https://en.wikipedia.org/wiki/Virtual_Network_Computing). Please see [these notes](https://github.com/sakaki-/gentoo-on-rpi-64bit/wiki/Run-a-Remote-VNC-Desktop-on-your-RPi) for further details.
   * For Windows users, [RDP](https://en.wikipedia.org/wiki/Remote_Desktop_Protocol) access is also supported (please see [these notes](https://github.com/sakaki-/gentoo-on-rpi-64bit/wiki/Access-your-RPi3%27s-Desktop-Remotely-from-a-Windows-Box-via-RDP) for further details).
