Typed out the message in slack and github was a pain to reformat so sorry for the image. |

Hi, I think it would be beneficial if you could post the signature of the ppollFunc (I presume you took pollFunc and adapted it accordingly) |

So far I took the normal pollFunc and adapted it into a ppollFunc. With that being said, I am not sure yet what should go inside so whole function call yet. As of now I am just trying to get it to accept the function declaration and hopefullly get past the Below is what I have made for the ppolFunc so far I do get that the function is most likley very incomplete but even with that when I go to recompile gem5 I get errors with the ABI In my se_workload.cc file within src/arch/arm/linux I have also attached the functions call, |

So is the ABI something I will also have to implement myself or did I already do something wrong with implementing the ppolfunc. Once again I get that the function contents may be very much missing but right now it seems like my functions parameters are not being accepted due to the abi? |

Hey, so I found a temporary solution — you can use ignoreFunc within the se_workload.cc file to handle certain syscall issues. For example, in my Rust code I needed to read files, and while the open and read syscalls worked, the statx syscall was causing problems. Even though statxFunc was implemented in syscall_emul.cc, it wasn’t linked in se_workload.cc. When I tried to link it like the other syscalls, it caused errors. As a workaround, I used ignoreFunc for statx, and then my Rust code ran successfully. So, if others are running into similar issues with Rust syscalls in gem5, especially with file-related operations, try using ignoreFunc as a workaround. |
