Tony Nguyen says: ==================== Jake Keller says: ==================== 100GbE Intel Wired LAN Driver Updates 2021-06-11 Extend the ice driver to support basic PTP clock functionality for E810 devices. This includes some tangential work required to setup the sideband queue and driver shared parameters as well. This series only supports E810-based devices. This is because other devices based on the E822 MAC use a different and more complex PHY. The low level device functionality is kept within ice_ptp_hw.c and is designed to be extensible for supporting E822 devices in a future series. This series also only supports very basic functionality including the ptp_clock device and timestamping. Support for configuring periodic outputs and external input timestamps will be implemented in a future series. There are a couple of potential "what? why?" bits in this series I want to point out: 1) the PTP hardware functionality is shared between multiple functions. This means that the same clock registers are shared across multiple PFs. In order to avoid contention or clashing between PFs, firmware assigns "ownership" to one PF, while other PFs are merely "associated" with the timer. Because we share the hardware resource, only the clock owner will allocate and register a PTP clock device. Other PFs determine the appropriate PTP clock index to report by using a firmware interface to read a shared parameter that is set by the owning PF. 2) the ice driver uses its own kthread instead of using do_aux_work. This is because the periodic and asynchronous tasks are necessary for all PFs, but only one PF will allocate the clock. The series is broken up into functional pieces to allow easy review. ==================== 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.
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.
