feat: BTF struct/offset support for KernelPatch and KPMs - #284
Conversation
|
I implemented this feature quite some time ago; BTF support is only enabled on kernels A13 and later (so I don't think it's suitable for the mainline, though it could serve as a feature branch). Additionally, BTF parsing can be performed during the kernel_init phase; for details, you can refer to my branch: https://github.com/niqiuqiux/KernelPatchUltra |

Looks good but i don't prefer using symbols to recognize position of the btf blob, since i know some kernels to strip rodata, it's preferable to let kptools search for it, similarly to how ikconfig works. |

The kernel's own BTF parsing also relies on symbols; additionally, since the BTF data is embedded in the boot image, it can be scanned during the kernel_init phase. I believe my branch offers the most convenient approach; you can check the relevant commit changes for details. |

well, as long as it works that's what's needed : D |
