11  * Coresight trace ID allocation API
13  * With multi cpu systems, and more additional trace sources a scalable
14  * trace ID reservation system is required.
26  * Trace ID maps will be created and initialised to prevent architecturally
30  * different sets of cpus trace into different independent sinks.
47  * Read and optionally allocate a CoreSight trace ID and associate with a CPU.
49  * Function will read the current trace ID for the associated CPU,
57  * return: CoreSight trace ID or -EINVAL if allocation impossible.
68  * Release an allocated trace ID associated with the CPU.
70  * This will release the CoreSight trace ID associated with the CPU.
72  * @cpu: The CPU index to release the associated trace ID.
83  * Read the current allocated CoreSight Trace ID value for the CPU.
89  * be changing, when perf starts and event on a core and outputs the Trace ID
109  * Allocate a CoreSight trace ID for a system component.
111  * Unconditionally allocates a Trace ID, without associating the ID with a CPU.
113  * Used to allocate IDs for system trace sources such as STM.
115  * return: Trace ID or -EINVAL if allocation is impossible.
120  * Allocate a CoreSight static trace ID for a system component.
122  * Used to allocate static IDs for system trace sources such as dummy source.
124  * return: Trace ID or -EINVAL if allocation is impossible.
129  * Release an allocated system trace ID.
131  * Unconditionally release a trace ID allocated to a system component.
133  * @id: value of trace ID allocated.
140  * Notify the Trace ID allocator that a perf session is starting.
143  * trace event.
145  * Perf sessions never free trace IDs to ensure that the ID associated with a
155  * zero, then all Trace IDs will be released.
