Kernel Call Trace是指内核调用跟踪,它是用于诊断Linux内核崩溃和故障的一种技术。当Linux内核遇到严重的错误或异常时,它会打印出一条Call Trace,它是一个函数调用链,显示了内核在出现错误之前执行的函数序列。
Call Trace通常包括函数名称、函数地址和调用堆栈信息。这些信息可以帮助内核开发人员追踪并诊断内核崩溃和故障的根本原因。使用Call Trace可以快速确定内核中出现问题的代码段,并找到相应的解决方案。
要查看Call Trace,您可以访问内核日志,通常位于/var/log/messages或/var/log/syslog。在日志中搜索"Call Trace"或"Kernel Oops"等关键字,以找到内核错误的详细信息和Call Trace。
总之,Kernel Call Trace是一个非常有用的工具,用于诊断Linux内核错误和故障。通过分析Call Trace,内核开发人员可以找到内核故障的根本原因并采取适当的措施加以解决。

CUDA kernel errors might be asynchronously reported at some other API call,so the stacktrace belo
CUDA kernel errors可能会在其他API调用时以异步方式报告,因此下面的堆栈跟踪可能不正确。为了调试,可以考虑传递CUDA_LAUNCH_BLOCKING=1。这意味着在GPU上运行程序时可能会出现报错:RuntimeError:CUDA error。由于代码在主机和设备之间是异步执行的,当设备抛出错误时,主机可能正在执行一些其他操作,这可能导致堆栈跟踪不准确。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

Copy info from "Call trace..." to a file(eg. dump.txt), and run command in your U-Boot project: ./scripts/stacktrace.sh dump.txt
As an AI language model, I don't have access to any specific project or file. But I can provide you with some general information on how to copy and run a command in U-Boot.
To copy information from "Call trace..." to a file (e.g., dump.txt), you can use any text editor or command-line utility. For example, you can use the following command in Linux:
```
dmesg > dump.txt
```
This will redirect the output of the "dmesg" command (which displays kernel messages) to a file named "dump.txt." You can also copy-paste the information manually from the console.
Once you have the dump.txt file, you can run the stacktrace.sh script in your U-Boot project. This script will analyze the call trace and provide a detailed stack trace report. To run the script, navigate to the U-Boot project directory and run the following command:
```
./scripts/stacktrace.sh dump.txt
```
This will run the stacktrace.sh script on the dump.txt file and generate a report. Make sure that you have the necessary permissions to run the script and that the dump.txt file is located in the correct directory.
