*nix mere end Linux

As the project's motto ("Of course it runs NetBSD" ) suggests, NetBSD has been ported to a large number of 32- and 64-bit architectures. These range from VAX minicomputers to Pocket PC PDAs. As of 2019, NetBSD supports 59 hardware platforms (across 16 different instruction sets)
...
This platform independence aids the development of embedded systems, particularly since NetBSD 1.6, when the entire toolchain of compilers, assemblers, linkers, and other tools fully support cross-compiling.

In 2005, as a demonstration of NetBSD's portability and suitability for embedded applications, Technologic Systems, a vendor of embedded systems hardware, designed and demonstrated a NetBSD-powered kitchen toaster.

Commercial ports to embedded platforms, including the AMD Geode LX800, Freescale PowerQUICC processors, Marvell Orion, AMCC 405 family of PowerPC processors, Intel XScale IOP and IXP series, were available from and supported by Wasabi Systems.

The kernel and userland for these platforms are all built from a central unified source-code tree managed by CVS.

1. The Yocto Project is widely adopted throughout the embedded/IoT industry. In addition to semiconductor and OS vendors, there are a number of vendors providing commercially supported Yocto Project software and services. The Yocto Project membership, associate and participant pages show the variety of industry players that are using the project. Industry initiatives such as the Genivi Alliance and Automotive Grade Linux help push Yocto Project adoption into the automotive industry. A simple job search on “yocto” will show you 100’s of job positions, worldwide.

2. Yocto Project works on any architecture.Either the silicon or ODM supplier has written a supportive BSP or if you have custom silicon, you can create a BSP following YP’s specifications. Yocto Project supports Intel, ARM, MIPS, AMD, PPC, and others.

59 hardware platforme? Skulle det være imponerende...

Jeg holder grinet inde og nøjes med et overbærende smil.

Men pointen er at kernel og userland er samme projekt.

Er det en god ting? Det reducerer vel mulighederne for at customisere. F.eks. kan man med Linux lave et ret kompakt system med en lille devicetree kernel og busybox, eller man kan lave en full blown desktop Linux. Baseret på samme kernel source.

Angående antal hardware platforme tror jeg vi taler lidt forbi hinanden. Med hardware platform tænker jeg på et stykke specifik hardware med en CPU på. Linux som embeddedt desktop eller android kører på ti-tusindvis, måske hundrede tusindvis af forskellige hardware platforme. Ja, jeg har selv lavet bring op på et par stykker i løbet af de sidste år.

Hvad mener de præcis med 59 platforme for BSD? Og hvorfor er det godt at de platforme er integreret i BSD projektet?

NetBSD understøtter 16 ISA. Det er ikke dårligt af en lille ret ukendt Unix distro.
