针对1:在kernel config中,Kernel Hacking这个大项中,enable跟lock/mutex相关的config,比如CONFIG_DEBUG_MUTEX,以及CONFIG_DETECT_HUNG_TASKS, 这样当死锁发生时,稍微等待一段时间(默认120秒),kernel就会检测到死锁,同时打印出调用栈。在kernel hacking里面,包含了大量的有利于调试的config,可以一项一项都看一遍,总有一款...

I'm getting kernel panics while running linux application on my custom hardware design(iMAX6Q processor based). But another custom hardware which is similar to this can run this linux application without any problem. I did the memory calibration and stress app test for this boa...
how to use for Linux kernel debug Michi Yama Guru10030points Hi, I have one question regarding XDS560. I heard that the I-cache/D-cache must be disabled when debugging the kernel of Linux. If you stop the execution of the code at brreakpoint without the cache d...
如果你已经有了一段代码想要放到内核树里,但是需要某种形式的帮助,那么kernel-mentors项目就可以帮你的忙了。这是一个邮件列表,可以在下面找到: http://selenic.com/mailman/listinfo/kernel-mentors 在你对Linux内核代码作任何实际的改动之前,必须要了解相关的代码是如何工作的。为了达到这个目的,没有比直接读它(很...
Recently, I've encounterd a kernel oops on a embedded linux system based on I.MX6ULL and 5.10.9 version of kernel. This issue has bothered me for
In order to activate debug messages during the boot process, even before userspace anddebugfsexist, use the kernel's command-line parameter:dyndbg For instance, the kernelbootargscan be modified in the following ways: Mount a boot partition from theLinuxkernel console, and then update the extl...
There are several ways to automatically configure networks in Linux-based systems. The most widely used option on desktops and notebooks is NetworkManager. Other network configuration management systems are mainly targeted for smaller embedded systems, such as OpenWRT’s netifd,Android’s ConnectivityManag...

Linux系统上的大多数系统配置文件都存放在/etc目录下。 从历史上看,每个程序都有一个或多个配置文件存放在这里,由于Unix系统上有很多软件包,/etc目录下的文件会很快积累起来。 There were two problems with this approach: It was hard to find particular configuration files on a running system, and it was...
