2.1. Supported Hardware

Debian does not impose hardware requirements beyond the requirements of the Linux or kFreeBSD kernel and the GNU tool-sets. Therefore, any architecture or platform to which the Linux or kFreeBSD kernel, libc, gcc, etc. have been ported, and for which a Debian port exists, can run Debian. Please refer to the Ports pages at https://www.debian.org/ports/powerpc/ for more details on 64-bit PowerPC (little-endian) architecture systems which have been tested with Debian GNU/Linux.

Rather than attempting to describe all the different hardware configurations which are supported for 64-bit PowerPC (little-endian), this section contains general information and pointers to where additional information can be found.

2.1.1. Supported Architectures

Debian GNU/Linux 11 supports 9 major architectures and several variations of each architecture known as flavors.

Architecture Debian Designation Subarchitecture Flavor
AMD64 & Intel 64 amd64    
Intel x86-based i386 default x86 machines default
Xen PV domains only xen
ARM armel Marvell Kirkwood and Orion marvell
ARM with hardware FPU armhf multiplatform armmp
64bit ARM arm64    
64bit MIPS (little-endian) mips64el MIPS Malta 5kc-malta
Cavium Octeon octeon
Loongson 3 loongson-3
32bit MIPS (little-endian) mipsel MIPS Malta 4kc-malta
Cavium Octeon octeon
Loongson 3 loongson-3
Power Systems ppc64el IBM POWER8 or newer machines  
64bit IBM S/390 s390x IPL from VM-reader and DASD generic

This document covers installation for the 64-bit PowerPC (little-endian) architecture using the Linux kernel. If you are looking for information on any of the other Debian-supported architectures take a look at the Debian-Ports pages.

This is the first official release of Debian GNU/Linux for the 64-bit PowerPC (little-endian) architecture. We feel that it has proven itself sufficiently to be released. However, because it has not had the exposure (and hence testing by users) that some other architectures have had, you may encounter a few bugs. Use our Bug Tracking System to report any problems; make sure to mention the fact that the bug is on the 64-bit PowerPC (little-endian) platform using the Linux kernel. It can be necessary to use the debian-powerpc mailing list as well.

2.1.3. Multiple Processors

Multiprocessor support — also called symmetric multiprocessing or SMP — is available for this architecture. Having multiple processors in a computer was originally only an issue for high-end server systems but has become common in recent years nearly everywhere with the introduction of so called multi-core processors. These contain two or more processor units, called cores, in one physical chip.

The standard Debian 11 kernel image has been compiled with SMP support. It is also usable on non-SMP systems without problems.

2.1.4. Graphics Hardware Support

Debian's support for graphical interfaces is determined by the underlying support found in X.Org's X11 system, and the kernel. Basic framebuffer graphics is provided by the kernel, whilst desktop environments use X11. Whether advanced graphics card features such as 3D-hardware acceleration or hardware-accelerated video are available, depends on the actual graphics hardware used in the system and in some cases on the installation of additional firmware images (see Section 2.2, “Devices Requiring Firmware”).

Details on supported graphics hardware and pointing devices can be found at https://wiki.freedesktop.org/xorg/. Debian 11 ships with X.Org version 7.7.

2.1.5. Network Connectivity Hardware

Almost any network interface card (NIC) supported by the Linux kernel should also be supported by the installation system; drivers should normally be loaded automatically.

2.1.6. Braille Displays

Support for braille displays is determined by the underlying support found in brltty. Most displays work under brltty, connected via either a serial port, USB or bluetooth. Details on supported braille devices can be found on the brltty website. Debian GNU/Linux 11 ships with brltty version 6.3.

2.1.7. Peripherals and Other Hardware

Linux supports a large variety of hardware devices such as mice, printers, scanners, PCMCIA/CardBus/ExpressCard and USB devices. However, most of these devices are not required while installing the system.
