1: [[!template id=port
16: NetBSD/evbarm is the port of NetBSD to various evaluation and prototyping
17: boards based on CPUs implementing the ARM architecture. NetBSD/evbarm also
18: supports some specific embedded system products based on prototype board
21: Matt Thomas is the maintainer of NetBSD/evbarm.
23: ### CPU types
25: The evbarm port can be built with a variety of CPU options, corresponding to the
26: [large array of ARM CPU architectures](https://en.wikipedia.org/wiki/ARM_architecture#Cores).
27: There are
28: four main variables: the word size, the instruction set, the
29: endianness, and whether there is hardware floating point. By default
30: the CPU type is "earm", and this implies aarch32 (32-bit), earmv5 cpu
31: architecture, little endian (el when explicitly stated), and soft
32: (Emulated) floating point. Another example, suitable for Raspberry PI
33: 2, is earmv7hf, which is aarch32, the v7 instruction set, little
34: endian, and hardware floating point.
36: Typically, various boards are best compiled with a CPU type that
37: matches the board's CPU and floating point support, but generally a
38: lower CPU instruction set version is workable on a newer board. See
39: build.sh and look for aliases for the evbarm port.
41: Through NetBSD 8, the evbarm port has supported exclusively the
42: aarch32 (32-bit CPU) sub-family of the ARM architecture. Some
43: processors, such as many supporting the armv8 CPU architecture, also
44: support a 64-bit instruction set, referred to as aarch64. This is
45: sometimes referred to as a distinct port, [[NetBSD/aarch64|aarch64]],
46: with code in src/sys/arch/aarch64, but it is built as the evbarm port
47: with aarch64 cpu type, and available as the alias evbarm64.
49: Note that MACHINE_ARCH=aarch64 currently refers to the A64 instruction
50: set and the aarch64 architecture, built for the armv8 architecture.
51: (Note also that armv8 is the first architecture to support aarch64, so
52: this will not be an issue until at least armv9.)
54: ### Kernels and userland
56: The evbarm userland can be used on any system that can run code of the
57: CPU type used for the build. Typically, a particular board requires a
58: kernel for that board.
60: ### anita and qemu
62: anita can be used to test builds. (In addition to anita, install qemu and dtb-arm-vexpress from pkgsrc.) The release subdirectory should follow the naming convention on the autobuild cluster, used below.
64: - evbarm-earmv7hf uses "qemu-system-arm -M vexpress-a15"
65: - evbarm-aarch64 uses "qemu-system-aarch64 -M virt"
66: - Information on how to test emulated versions of other specific hardware is welcome.
