How bylaws/libadrenotools works

Adreno Tools is a developer library for rootless Adreno driver modifications, not an end-user driver installer. An app calls the library to load a custom Vulkan driver and optionally enable file redirection or GPU mapping; the library configures and loads hook components, while a separate API applies BCn patches. The tree also contains Vulkan acceleration and Qualcomm mapper shims. Source excerpts do not establish how those standalone shims are consumed, so their integration links are omitted.
