我在带有 ARM9 内核的嵌入式目标上使用 Linaro 版本的 Linux (Linaro 12.11)。对于特定的分析，我需要使用性能工具。 perf 要求在我的设备上安装 linux-tools-3.15.0。但所有这样做的尝试都是徒劳的。最后我尝试了
sudo wget --no-check-certificate "https://launchpad.net/~canonical-kernel-team/+archive/ppa/+build/5980376/+files/linux-tools-3.15.0-0-generic_3.15.0-0.1_armhf.deb"
但它给出了结果

答案1
这是因为该文件不存在。据我所知，这perf是软件包的一部分。linux-tools
您应该能够通过传统方式apt-get install linux-tools从标准源安装它。如果没有，请发布您尝试时发生的情况以及您使用的内核版本。
