Can you test |
Compiling suitable kernel for testing |

The kernel is still being tested. Most of the current tests have passed, but there are still some problems. It will be submitted after all the tests are passed. |

Thank you very much for this effort! |

Are you on a 6.8-rc kernel? Anyway, you just need to rebase on master since this: #1632 was just merged yesterday. |

While testing the kmo module, I found some problems with the execution of the test case that makes the splice system call, but I'm not sure if it's consistent in other architectures error log: I looked up PPM_SPLICE_F_MOVE macro definition as follows: |
I found the reason... #1181 (comment) The currently problematic test case: |
The reason has been found, since the schema should be defined as __loongarch64 instead of loongarch |
|
@FedeDP The current good news is that the kmod module has all passed the test |
|
@yzewei no problem sir! And thank for the great effort you are putting into this! |
Thanks for your understanding! There is another news, I almost forgot, the bpf and modern-bpf modules based on loongarch architecture are also on the way. |
|
@FedeDP We are currently migrating and adapting the ebpf module and have found a problem that may not exist in other architectures, as described below: |
|
Argh, not really an expert in this area. Summoning @Andreagit97 :) |
Thanks！ |

In the current pr, commit loongarch's support for the driver module |
|
@FedeDP Due to some problems with the bpf module, we are still communicating with the llvm community and may continue to submit relevant PR in the future. |
|
You are welcome (also, you did a great great job btw!) |

Out of curiosity, can you share the errors you were having here?
We are having a very similar issue in the open related test cases for ppc64le: #1739

Also, i'd use ifndef in this case and leave a comment explaining the issues on the arch ;)

I'm adding a judgment here because there is no fstat syscall call under the loongarch architecture. Let's take a look at the error situation without adding a judgment
There was a problem hiding this comment.
@FedeDP A compile error occurred because fstat could not be found.
I found fstat in the ppc64 system call table, so this shouldn't be a problem
#ifndef __NR_fstat
#define __NR_fstat 108
#endif
