Thomas Richter says: ==================== The PAI PMUs pai_crypto and pai_ext both operate on memory mapped counters supported by z16 and follow on machines. These memory mapped counters have a lot in common, like: - validation, installing and removing events - starting and stopping events - retrieving counter values - collecting sample data. However both PMU drivers have slightly different parameters, for example: - different mapped memory size - different number of supported counters - different counter numbers and names - different bits in the CR0 register - different anchor address in lowcore Due to these different parameters, two independent PMUs have been developed. However both PMU drivers have very much in common and most of the PMU call back functions look very similar and are sometimes identical. This patch set combines both independent PMU device drivers perf_pai_crypto.c and per_pai_ext.c into one device driver. The new device driver operations on a table which contains the different parameters and uses common functions for event operations. Result is one PAI PMU driver which supports both PMUs. It is also extendable to support new PAI PMUs. ==================== Signed-off-by: Heiko Carstens <hca@linux.ibm.com> |

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.
