/**
|
* DOC: KTrace version history, JM variant
|
*
|
* 1.0:
|
* Original version (implicit, header did not carry version information).
|
*
|
* 2.0:
|
* Introduced version information into the header.
|
*
|
* Some changes of parameter names in header.
|
*
|
* Trace now uses all 64-bits of info_val.
|
*
|
* Non-JM specific parts moved to using info_val instead of refcount/gpu_addr.
|
*
|
* 2.1:
|
* kctx field is no longer a pointer, and is now an ID of the format %d_%u as
|
* used by kctx directories in mali debugfs entries: (tgid creating the kctx),
|
* (unique kctx id).
|
*
|
* ftrace backend now outputs kctx field (as %d_%u format).
