 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 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; real-time video playback). The Pi's onboard Ethernet, WiFi (dual-band on the RPi3 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.
