commit 96a720db59ab330c8562b2437153faa45dac705f upstream.
There was a mistake in the SNR uncore spec. The counter increments for
every 32 bytes of data sent from the IO agent to the SOC, not 4 bytes
which was documented in the spec.
The event list has been updated:
"EventName": "UNC_IIO_BANDWIDTH_IN.PART0_FREERUN",
"BriefDescription": "Free running counter that increments for every 32
bytes of data sent from the IO agent to the SOC",
Update the scale of the IIO bandwidth in free running counters as well.
Fixes: 210cc5f9db ("perf/x86/intel/uncore: Add uncore support for Snow Ridge server")

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.
