Umesh Nerlige Ramappa c61d04c9eb drm/i915/perf: Add engine class instance parameters to perf
One or more engines map to a specific OA unit. All reports from these
engines are captured in the OA buffer managed by this OA unit.

Current i915 OA implementation supports only the OAG unit. OAG primarily
caters to render engine, so i915 OA uses render as the default engine
in the OA implementation. Since there are more OA units on newer
hardware that map to other engines, allow user to pass engine class and
instance to select and program specific OA units.

UMD specific changes for GPUvis support:

README

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 Restructured Text 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.
