| NetBSD/evbarm is the port of NetBSD to various evaluation and prototyping |
NetBSD/evbarm is the port of NetBSD to various systems based on chips |
| boards based on CPUs implementing the ARM architecture. NetBSD/evbarm also |
implementing the ARM architecture. The "evb" component is a reference |
| supports some specific embedded system products based on prototype board |
to evaluation boards, the original target of the port, but this |
| designs. |
is no longer relevant - NetBSD/evbarm now runs on a range of |
| |
hardware based on APCI or devicetrees, including a range of development |
| |
boards, powerful servers, virtual machines, and even some laptops. |

| ### CPU types |
### CPU types |
| |
|
| The evbarm port can be built with a variety of CPU options, corresponding to the |
Various CPU variants are supported, e.g: |
| [large array of ARM CPU architectures](https://en.wikipedia.org/wiki/ARM_architecture#Cores). |
|
| There are |
|
| four main variables: the word size, the instruction set, the |
|
| endianness, and whether there is hardware floating point. By default |
|
| the CPU type is "earm", and this implies aarch32 (32-bit), earmv5 cpu |
|
| architecture, little endian (el when explicitly stated), and soft |
|
| (Emulated) floating point. Another example, suitable for Raspberry PI |
|
| 2, is earmv7hf, which is aarch32, the v7 instruction set, little |
|
| endian, and hardware floating point. |
|
| |
|
| Typically, various boards are best compiled with a CPU type that |
|
| matches the board's CPU and floating point support, but generally a |
|
| lower CPU instruction set version is workable on a newer board. See |
|
| build.sh and look for aliases for the evbarm port. |
|
| |
|
| Through NetBSD 8, the evbarm port has supported exclusively the |
|
| aarch32 (32-bit CPU) sub-family of the ARM architecture. Some |
|
| processors, such as many supporting the armv8 CPU architecture, also |
|
| support a 64-bit instruction set, referred to as aarch64. This is |
|
| sometimes referred to as a distinct port, [[NetBSD/aarch64|aarch64]], |
|
| with code in src/sys/arch/aarch64, but it is built as the evbarm port |
|
| with aarch64 cpu type, and available as the alias evbarm64. |
|
| |
|
| Note that MACHINE_ARCH=aarch64 currently refers to the A64 instruction |
|
| set and the aarch64 architecture, built for the armv8 architecture. |
|
| (Note also that armv8 is the first architecture to support aarch64, so |
|
| this will not be an issue until at least armv9.) |

|
| NetBSD developer Jared McNeill provides [builds of NetBSD 9 and -current for a vast variety of hardware.](https://www.armbsd.org/) In addition to the standard build, these images have board-specific U-Boot contents. See also /usr/pkgsrc/sysutils/u-boot*. |
- evbarm-earmv6hf - ARMv6 with EABI and hardware floating point, e.g. |
| |
the original Raspberry Pi. |
| |
- evbarm-earmv7hf - ARMv7 with EABI and hardware floating point, e.g. |
| |
most recent and common 32-bit ARM boards. |
| |
- evbarm-earmv7hfeb - Same as the above, but with the CPU running in |
| |
big endian mode. |
| |
- evbarm-aarch64 - 64-bit ARMv8 |
| |
- evbarm-aarch64eb - Same as the above, but with the CPU running in |
| |
big endian mode. |
| |
|
| |
Since NetBSD 9.0, 64-bit ARM processors are supported (referred to here |
| |
as aarch64). These run with fully 64-bit kernels and userland. Running |
| |
32-bit ARM binaries is also supported with `compat32`. |
| |
|
| |
evbarm variants are little endian unless otherwise stated. NetBSD provides |
| |
big endian images primarily for testing purposes and to ensure that the code |
| |
is endian-clean. |
