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), \todo 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: ### Kernels and userland
51: The evbarm userland can be used on any system that can run code of the
52: CPU type used for the build. Typically, a particular board requires a
53: kernel for that board.
55: ### anita and qemu
57: 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.
59: - evbarm-earmv7hf uses "qemu-system-arm -M vexpress-a15"
60: - evbarm-aarch64 uses "qemu-system-aarch64 -M virt"
61: - Information on how to test emulated versions of other specific hardware is welcome.
