Go Wiki：ARM 上的 Go
简介
Go 在 Linux 和 Darwin 上得到完全支持。任何您可以为 x86/x86_64 编译的 Go 程序都应该可以在 Arm 上运行。除了 Linux 和 Darwin 之外，Go 还实验性地支持 FreeBSD、OpenBSD 和 NetBSD。
支持的架构
Go 支持以下 ARM 架构系列。
| 架构 | 状态 | GOARM 值 | GOARCH 值 |
|---|---|---|---|
| ARMv4 及以下 | 不支持 | n/a | n/a |
| ARMv5 | 支持 | GOARM=5 | GOARCH=arm |
| ARMv6 | 支持 | GOARM=6 | GOARCH=arm |
| ARMv7 | 支持 | GOARM=7 | GOARCH=arm |
| ARMv8 | 支持 | n/a | GOARCH=arm64 |
| ARMv9 | 支持 | n/a | GOARCH=arm64 |
从 Go 1.1 开始，如果您在目标机器上从源代码编译程序，则会选择合适的 GOARM 值。在交叉编译的情况下，建议您始终设置合适的 GOARM 值以及 GOARCH 值。
支持的操作系统
- Linux 上的 ARM。您必须运行 EABI 内核。这些通常被称为
armel（用于软浮点，兼容 ARMv5）或armhf（用于硬件浮点，ARMv6 及以上）。 - Darwin 上的 ARM：需要 ARMv7。
- FreeBSD、OpenBSD 和 NetBSD 上的 ARM：需要 ARMv6K 或更高版本。
推荐的 Go 版本
Go 对 ARM 系统有成熟的支持；因此，就像其他架构一样，使用最新的稳定版本（例如：撰写本文时为 Go 1.18）。
提示和技巧
/tmp 和 tmpfs
go 构建工具在编译和测试时使用 /tmp，如果 /tmp 位于您的 SD 卡上，这会导致严重的磨损。为了最大程度地减少这种影响，可以将 export TMPDIR 设置到另一个文件系统上的某个位置。或者，如果您有大量的物理内存，可以通过将以下行添加到 /etc/fstab 中，在 /tmp 上挂载一个以交换空间为后端的 tmpfs 文件系统
tmpfs /tmp tmpfs nodev,nosuid,mode=1777 0 0
交换空间
从源代码构建 Go 需要至少 256MB 的 RAM。运行测试需要至少 256MB 的内存和至少 512MB 的交换空间。
由于资源不足导致的测试失败
运行时测试会创建许多本机操作系统线程，在默认情况下每个线程 8MB，这可能会耗尽具有 32 位用户模式地址空间的 ARM 系统（尤其是在 Raspberry PI 2 等多核 ARM 系统上）。为了防止运行时测试失败，您可能需要降低线程堆栈限制
% ulimit -s 1024 # set the thread stack limit to 1mb
% ulimit -s # check that it worked
1024
有关详细信息，请参阅 Dave Cheney 关于在 Raspberry Pi 上构建 Go 的博客文章。
由于内存不足导致的构建失败
Go 工具在安装包时（在 make.bash 期间）会尝试让所有 CPU 内核保持忙碌状态，这在内存充足的 PC 上通常是首选。但是，一些功能强大的多核 ARM 机器没有足够的内存来支持利用所有可用内核的并行构建，您可以使用 taskset(1) 实用程序将 Go 限制为仅使用一个内核来解决此问题，而无需使用交换空间。
taskset 1 ./make.bash # use 3 if you want to use two cores
注意：此处的 1 是 CPU 亲缘性的位掩码，它不是您愿意使用的 CPU 内核数，有关详细信息，请参阅 taskset(1) 手册。
已知问题
ARMv5 上缺少浮点硬件
ARMv5 的主要问题是常见 ARMv5 硬件† 缺少浮点支持。当使用 GOARM=5 环境变量进行编译时，5l 链接器会在任何浮点指令块之前插入对 _sfloat 的调用，以分支到浮点模拟器。这意味着使用已使用软浮点支持编译的 Go 安装生成的二进制文件将在所有受支持的架构上工作，但没有软浮点支持编译的构建将无法在 ARMv5 上工作。
† 这并不完全正确，存在具有 VFP1 浮点的 ARMv5 实现。但是编译器尚不支持 VFP1。
html/template 和 test/nilptr.go 测试在 HTC Android 上失败
已知 html/template 测试和 test/nilptr.go 在 HTC 的 Android 内核上失败 (参考)，因为内核将在 10 次段错误后终止应用程序。
QNAP 219P 上 2.6.32-5-kirkwood 中潜在的内核错误
有关详细信息，请参阅 问题 5466。更新到 3.2.0-4-kirkwood 解决了该问题。
成功案例
ARM 硬件有多种形状和大小。如果您在您的 Arm 系统上构建和运行 Go 获得了成功，请在此处详细说明您的结果。
Netgear Stora
架构：ARMv5
操作系统：Debian Sid
Netgear Stora 是一个 ARMv5（Marvell Kirkwood）平台。我用 Debian Sid 发行版刷过我的 Stora，在 Go1 之前，它一直是 Go 开发的可靠平台。主要缺点是 Stora 只有 128MB 的 RAM，这对于运行 ./all.bash 来说还不够，因为 5l 在链接某些命令时可能会使用超过 100MB 的 RAM。
有关在您的 Stora 上安装 Debian 的说明，请参阅 OpenStora 网站：http://www.openstora.com/wiki/index.php?title=How_to_install_Debian_Linux_on_NETGEAR_Stora。

Qnap TS-119P II
架构：ARMv5
操作系统：Debian Squeeze
Qnap TS 系列 NAS 是极好的可破解的小型 Linux 主机。TS-11P9 II 是一个 2GHz Marvell Kirkwood ARMv5 处理器，具有 512MB 的 RAM 和一个 SATA 驱动器托架。
kirkwood 平台受原生 Debian 安装程序支持。 http://www.cyrius.com/debian/kirkwood/qnap/ts-119/install.html

Pandaboard
架构：ARMv7
操作系统：Ubuntu 12.04LTS (armhf)
Pandaboard 是基于 Texas Instruments OMAP4 SoC 平台的双核 ARMv7 开发板。我在我的 Pandaboard 上运行 Ubuntu 12.04 LTS 服务器，这是一个非常适合 Arm 开发的发行版。Pandaboard 有 1GB 的 RAM，这使其非常适合开发和基准测试。
有关说明和 SD 卡映像，请参阅 Ubuntu wiki：https://wiki.ubuntu.com/ARM/Server/Install#Installing_pre-installed_OMAP4_Precise_.2812.04.29_Server_Images。

BeagleBone
架构：ARMv7 单核，Cortex-A8，256MB RAM，720 MHz
操作系统：Angstrom Linux
BeagleBone 类似于 Beagleboard，但没有视频组件。Angstrom 是一个非常小的基于 ARM 的系统的 Linux 发行版。它构建在 Yocto 和 OpenEmbedded 之上，并带有额外的工具和配方，使其更容易构建发行版。您可以将 Angstrom 视为 Ubuntu，将 OpenEmbedded/Yocto 视为 Debian。与 Ubuntu 相比，Angstrom 非常轻量级且快速。它使用 systemd 而不是 sys5 脚本，这有助于提供几秒钟的快速启动时间。
BeagleBone 可能比 RaspberryPI 更快，因为它具有更新的 Cortex-A8 双发行超标量架构，但 PI 具有 GPU，理论上可以使用 OpenCL 等工具来真正超越 BeagleBone。但是，对于嵌入式应用程序，BeagleBone 更易于使用，因为它开箱即用，具有 GPIO 连接。
我已从 Mac 使用 5g 交叉编译到 ARM，到目前为止，我还没有遇到任何问题。您可以在 BeagleBone 上构建，但使用 Go 进行交叉编译非常容易，因此最好节省闪存驱动器的磨损，只需在其他地方进行编译即可。

架构：ARM5 平台：Debian Wheeze
成功构建了默认分支，将使用 golang 为该设备编写风扇控制守护进程。

AppliedMicro X-Gene (ARMv8)
架构：ARMv8（64 位）8 核，2.4GHz，16GB RAM
操作系统：Linux，Fedora 21
您需要使用 bootstrap.bash 交叉编译工具链。将它复制到 arm64 系统并设置 GOROOT_BOOTSTRAP 后，您就可以本地构建 go 了。
96Boards HiKey (ARMv8)
架构：ARMv8（64 位）8 核，1.2GHz，1GB RAM
操作系统：Linux (Linaro)
Go版本：1.5 Beta1
特别说明：启用交换分区（<=1GB 即可）。构建过程会占用大量 CPU，可能导致内部温度超过 90°C 的阈值 - 在构建过程中保持 HiKey 冷却。
如上所述，使用 bootstrap.sh（例如在 Ubuntu AMD64 上）用于 ARM64，然后传输 bootstrap tbx 文件，解压缩它，并将其用作 GOROOT_BOOTSTRAP。将 Go 源代码检出到单独的 GOROOT 中，然后构建。

Jetson Nano
英伟达® 的 Jetson Nano™ 是一款高性能低功耗单板计算机，专为边缘人工智能计算而构建。它拥有基于 ARM57 的四核 CPU，主频为 1.43 Ghz，基于 Maxwell 的 128 核 GPU 以及 4GB 的 LPDDR4 内存，带宽为 25.6 GB/s。
架构：ARMv8-A
操作系统：Jetson Nano 开发套件（Ubuntu 18.04 LTS），带有 JetPack 4.2
内核：我使用了一个自定义编译的官方内核，其中包含启用 Zswap 和将根文件系统放在 USB SSD 上的补丁。执行此操作的步骤在Syonyk 的博客中详细介绍。

苹果硅
交叉编译 Go 应用程序
主机/构建：macOS/x86_64 目标：macOS/arm64 在主机上
Xcode：安装支持苹果硅的最新 Xcode
Go：在 macOS/x86_64 上安装 go*.darwin-amd64.pkg（或从源代码构建 Go）
在 PATH 中设置 go 可执行文件
在交叉编译用于 macOS/arm64 的 Go 应用程序之前，导出以下环境变量
export SDK_NAME=macosx
export SDK_PATH=$(xcrun --show-sdk-path --sdk $SDK_NAME)
export CGO_ENABLED=1
export GOOS=darwin
export GOARCH=arm64
export CC="$(xcrun -sdk $SDK_PATH --find clang) -arch $GOARCH -isysroot $SDK_PATH"
export CFLAGS="-isysroot $SDK_PATH -arch $GOARCH -I$SDK_PATH/usr/include"
export LD_LIBRARY_PATH="$SDK_PATH/usr/lib"
export CGO_CFLAGS="-isysroot $SDK_PATH -arch $GOARCH"
export CGO_LDFLAGS="-isysroot $SDK_PATH -arch $GOARCH"
Compile the app as below:
$ GOOS=darwin GOARCH=arm64 go build <app>
将生成的 arm64 可执行文件复制到目标机器（macOS/arm64）并运行
