Antoine Tenart says: ==================== net: mvpp2: improve the interrupt usage This series aims to improve the interrupts descriptions and usage in the Marvell PPv2 driver. - Before the series interrupts were named after their s/w usage, which in fact can be configured. The series rename all those interrupts and add a description of the ones left over. - In PPv2 the interrupts are mapped to vectors. Those vectors were directly mapped to a given CPU, and per-cpu accesses were done. While this worked on our cases, the registers accesses mapped to the vectors are not actually linked to a given CPU. They instead are linked to what is called a "s/w thread". The series modify this so that the s/w threads are used instead of the CPU numbers, by adding an indirection. This means we now can have systems with more CPUs than s/w threads. This is based on today's net-next, and was tested on various boards using both versions of the PPv2 engine. Two more patches will be coming, to update the device trees describing a PPv2 engine. The patches are ready, but will go through a different tree. I'll send them once this series will be accepted. This is not an issue as the PPv2 driver keeps the dt bindings backward compatibility. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
