classabbyamp 98f0d74792 dkms: depend on pahole ... CONFIG_DEBUG_INFO_BTF_MODULES is enabled on most/all void kernels, and thus pahole is used when generating BTF information during compilation of external modules. on cross-built kernels, the absence of pahole will remove CONFIG_DEBUG_INFO_BTF_MODULES from /usr/src/kernel-headers-$version/include/generated/autoconf.h when the dkms kernel.d hook runs for the first time (because cross-built kernels have their host tools removed). When this is removed, part of the module struct in include/linux/module.h is missing, resulting in a mismatch in the size of the __this_module struct (.gnu.link_once.this_module section of the .ko) in external modules of exactly 64 bytes. struct module { // ... #ifdef CONFIG_DEBUG_INFO_BTF_MODULES unsigned int btf_data_size; void *btf_data; #endif // ... } fixes #51005		2024-06-26 13:02:54 -04:00
