32  * Hardware Tracing framework.
34  *    The framework manages hardware tracing units that collect information
44  * calls to allow user to manage CPU (hardware) tracing units.
50  *                  Allocates kernel tracing context CTX based on requested mode
57  *        Maps tracing buffers of the corresponding thread to userspace.
61  *                  Enables tracing unit for a given context.
82  *    Some architectures may have different tracing units supported, so user

98  * 5. User mmaps tracing buffers of each thread to userspace (using
111  * 2. Kernel verifies the set of CPU and allocates tracing context, creates
