Perfcnt samples buffer is not exposed to UM, but we would like to keep a tag on it as a potential debug aid. PRIME imported GEM buffers are UM exposed, but since the usual Panfrost UM driver code path is not followed in their creation, they might remain unlabelled for their entire lifetime, so a generic tag was deemed preferable. The tag is assigned before a UM handle is created so it doesn't contradict the logic about labelling internal BOs.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
