raspberry pi官网的编译手册写的简洁有力,照着操作即可 https://www.raspberrypi.org/documentation/linux/kernel/building.md CROSS-COMPILING First you are going to require a suitable Linux cross-compilation host. We tend to use Ubuntu; since Raspbian is also a Debian distrib…

How to emulate a Raspberry Pi on your PC I am very interested in trying simulators and emulators for popular IoT devices. One of those is the Raspberry Pi. As I was searching for simulators, I found that one of the best ones is QEMU. I found lots of…

  Compiling custom kernel has its own advantages and disadvantages. However, new Linux user / admin find it difficult to compile Linux kernel. Compiling kernel needs to understand few things and then just type couple of commands. This step by step ho…

How to compile and install Linux Kernel 5.1.2 from source code Compiling a custom kernel has its advantages and disadvantages. However, new Linux user/admin find it difficult to compile Linux kernel. Compiling kernel needs to understand few things an…

Over the last few months I’ve been playing with MultiPath TCP and in this post I will show how I use it to leverage my humble True ADSL line at home. For performance and security reasons, I tunnel all my traffic thru a VPN. This is not necessarily to…

Kernel Building https://www.raspberrypi.org/documentation/linux/kernel/building.md There are two main methods for building the kernel. You can build locally on a Raspberry Pi which will take a long time; or you can cross-compile, which is much quicke…

Computer Shader是什么? Computer shader是一段运行在GPU上的一段程序. 什么时候用Computer shader? 假如我们把一个cube当作单独的点,用许多个(cube)点来组成一个变换矩阵. 每帧cpu都需要对矩阵的点进行排序,批处理,将每个点位置复制给GPU,URP每帧需要执行两次,DRP必须执行至少三遍. 当100*100个点时,也许我们的cpu可以轻松应对,但如果我们想组成分辨率更高的图形,1000 * 1000,一百万个点时,CPU和GPU的工作量会大…

Compiling a kernel module for the raspberry pi 2 via Ubuntu host Normally compiling a kernel module for a linux distribution is rather straight forward, but on the raspberry pi however it's a little more involved. That's why in this article I am goin…

ABSTRACT There are two main methods for building the kernel. You can build locally on a Raspberry Pi which will take a long time; or you can cross-compile, which is much quicker.There is an introduction about cross-compilation as follows. You need ub…
