Commit Message

Dixit Parmar June 5, 2025, 12:54 p.m. UTC 
Added testcase to validate kernel-module-split.bbclass functionality
based on the KERNEL_SPLIT_MODULES option values[enabled/disabled].
The test cases validates the generation of the kernel module
autoload/modconf .conf files.
Introduces two testcases:
kernel_module_split.KernelSplitAutoloadTest.test_split_modules_disabled
kernel_module_split.KernelSplitAutoloadTest.test_split_modules_enabled
