Linux Lab released v0.2-rc2, to support the development of real-time Linux v5.2

Linux Lab  is a real-time laboratory for learning Linux kernel, development and testing, speed can be set up and to use, powerful, it is easy to use!

You can use it to learn efficiently processor architecture, Linux kernel, embedded Linux, C programming language, compilation of Linux, Shell programming.

If you want to learn Linux 0.11 kernel and Linux X86 assembly language, you can also visit another two Lab, namely  Linux 0.11 Lab  and  CS630 Qemu Lab .

new version update

Following the July 23 release  v0.2 rc1  later, Linux Lab released today: v0.2-RC2 , in addition to repair some of the features this version perfect document, but added experimental support for real-time Linux v5.2, adds a docker image tags acquisition tool, a new board-level configuration tools, and allows you to set the number of parallel compiler threads.

This version v0.2 rc1 compared to only 14 pen modify, update mainly as follows:

• New experimental support for real-time Linux v5.2
  • Add  feature/linux/rt/v5.2/, may, like other features, a command to turn on the feature: make f f=rtthe command will be marked with patch and complete kernel configuration. Currently only  i386/pc the verification can be started normally.
  • Reference may add other versions of rt patch.
• Added a docker image tags acquisition tools
  • tools/docker/tags.shThe experimental environment is mainly used in the subsequent Linux Lab offered upgrades.
• Added board-level configuration tool
  • tools/board/config.shAllows simple board configuration updates, without having to manually modify the configuration file: make board-config LINUX=v5.2.
• Godson Godson new plug-education R & D support
  • Loongson plug-ins  to add  loongson/ls232 support.
• It allows you to set the number of parallel compiler threads
  • By  make JOBS=n the number of threads parallel compiler specified, the default is set to the number of processors
• Repair and improve some functions using the document
  • New noVNC occasionally Desktop does not respond to the approach
  • New plug-in support Godson information
• Other minor adjustments
  • examples/c/hello, The new  -Wall -Werror mandatory static checking.
  • New gdb-multiarch debugging support in the docker mirror, avoid installing a gdb for each platform
  • The introduction of board-level repair after the introduction of customized warehouse source path error problem
  • All kernel always use the new version  scripts/config, the old version to fix the problem

Speed ​​experience

In the non-Ubuntu platform, pre-installed on their own good docker:

$ git clone https://gitee.com/tinylab/cloud-lab.git
$ cd cloud-lab
$ tools/docker/run linux-lab

Such as local've downloaded Linux Lab, we recommended back  cloud-lab catalog upgrade docker image and reboot Linux Lab:

$ tools/docker/pull linux-lab
$ tools/docker/rerun linux-lab

Into the future, open the console, type the following command to start a board:

$ make boot

Speed ​​experience Qemu + RealTime Linux v5.2:

$ make BOARD=i386/pc
$ make kernel-download
$ make kernel-patch
$ make kernel-defconfig

// Add real time linux patch and enable it
$ make f f=rt
$ make kernel-olddefconfig

$ make kernel
$ make boot

Key Features

Linux Lab has the following characteristics:

1. Support the three major operating systems (Windows, MacOS, Linux), it can easily be used in these three operating systems.
2. Support 7+ large processor architecture (X86, ARM, MIPS, PPC, Csky, Risc-V, Loongson), which Loongson and Csky for domestic processors.
3. Support 15+ paragraph development board (i386 / pc, x86_64 / pc, arm / versatilepb, arm / vexpress-a9, ppc / g3beige, mips / malta, aarch64 / virt, aarch64 / raspi3, riscv32 / virt, riscv64 / virt, csky / virt, loongson / ls1b, loongson / ls2k, loongson / ls232, loongson / ls3a7a).
4. Supports five landing approach (docker, ssh, vnc, webssh, webvnc), can be accessed locally or remotely accessible.
5. Five integrated components (Qemu, U-boot, Buildroot, Linux, Toolchain), has a pre-compiled version.
6. Built five major platforms, 32-bit and 64-bit total of 10 Hello World assembly language routines, see  examples/assembly.
7. You can learn processor instruction set, Qemu, Shell, Assembler, C, Linux kernel, embedded Linux.
8. Support Debugging and Testing.
