![]() More recently (when?) an alternative driver (what's the name of that driver?) has become available that drives the 3D core in the GPU directly from the ARM rather than passing messages to the VPU core in the GPU which in turn drove the 3D core. This is better than some other GPUs because the ARM part can be rebuilt. This means that any issues with OpenGL cannot be fixed nor performance improved. The 3D driver for the Raspberry Pi, while Free Software, is just a shim that passes OpenGL commands directly to the non-free software running on the GPU (does this also apply for the vc4 driver in the RPi 4?).While schematics are available the board design is closed and the main processor is not available for purchase by the general public.While some hardware documentation has been released the documentation is sorely lacking.(Editor Question: isnt this also true for the 4?) Even starting the machine requires a large (2MB) blob of non-free, unsupportable software. 2021-06, the binary blob for the GPU is non-free. This needs a binary blob used by the GPU present on the boot medium for the system to boot. All models before the Raspberry Pi 4 boot from the GPU.As of November 2020, there is work in progress to integrate it into both the Linux kernel and Mesa for the Raspberry Pi 4. Therefore 3D applications will currently require Pi specific builds. 3D acceleration is not integrated with X or other standard mechanisms.That is a decision that you will have to make given your application, below are some pros and cons that you should consider. The Zero uses the same SoC/CPU as the first version, so they should function identically. While Raspberry Pi OS solves this to some degree an unofficial port will always give less certainty than an official one. The Raspberry Pi 1's processor falls uncomfortably between the processor families that Debian has chosen to target, between armel and armhf. The first generation Raspberry Pi systems runs on Debian armel. In 2015, the Zero model was announced, using the same CPU as the 1 family but with a smaller form factor, followed by the Zero W, which adds wireless connectivity. This family was expanded by very similar models A+ and B+. The systems now known as Raspberry Pi model 1 models A and B were announced in February 2012. Raspberry Pi 1 (A, B, A+, B+, Zero, Zero W) You can refer to the RaspberryPi2 page, which aims to collect more detailed information how to run Debian on this hardware. Second-generation Raspberry Pi systems (model 2 only) runs on Debian armhf. The only member of this family is the Raspberry Pi 2. The second generation systems were announced on 2014. For further details and information on how to run with this hardware, go to the RaspberryPi3 page. Some models include wireless connectivity. The Raspberry Pi 3 was announced in 2016, and is the first 64-bit member of the family. RPi 4 images work on the Pi 400, although a different DTB (not yet available/mainlined as of Linux 5.10) is needed for some hardware support, i.e. The Raspberry Pi 400, announced in November 2020, is quite similar to the Raspberry Pi 4 B models. More technical details about Raspberry Pi 4 support are available on the RaspberryPi4 page. You can also run regular Debian on your Raspberry Pi's! (keep reading.)Īnnounced in 2019, this system adds a second HDMI port, more memory, true Gigabit Ethernet and USB3. Questions related to Raspberry Pi OS should be asked on (f.e.) their forums. Raspberry Pi OS is not affiliated with the Debian project. Raspberry Pi OS builds a single image for all of the Raspberry families, so you will get an armhf 32-bit, hard floating-point system, but built for the ARMv6 ISA (with VFP2), unlike Debian's ARMv7 ISA (with VFP3) port. This is, first of all, for historical reasons (booting a mainline Linux kernel was not supported on Raspberries until late 2018), but also because of other non-free components that are shipped as part of Raspberry Pi OS (such as Oracle Java, Wolfram Mathematica, and several games such as a Pi-specific Minecraft version). The most often used distribution across all raspberries is Raspberry Pi OS (originally known as Raspbian), a derivative of Debian. Raspberry Pi OS (formerly Raspbian) and Debian This binary blob is available in the non-free Debian repository, packaged as the raspi-firmware package (or raspi3-firmware until Debian 10). To know more, please read on.Īll Raspberry Pi models before the 4 (1A, 1B, 1A+, 1B+, Zero, Zero W, 2, 3, Zero 2 W) boot from their GPU (not from the CPU!), so they require a non-free binary blob to boot.
