Tariq Toukan says: ==================== net/mlx5e: Add support for PCIe congestion events Dragos says: PCIe congestion events are events generated by the firmware when the device side has sustained PCIe inbound or outbound traffic above certain thresholds. The high and low threshold are hysteresis thresholds to prevent flapping: once the high threshold has been reached, a low threshold event will be triggered only after the bandwidth usage went below the low threshold. This series adds support for receiving and exposing such events as ethtool counters. 2 new pairs of counters are exposed: pci_bw_in/outbound_high/low. These should help the user understand if the device PCI is under pressure. Planned followup patches: - Allow configuration of thresholds through devlink. - Add ethtool counter for wakeups which did not result in any state change. ==================== Link: https://patch.msgid.link/1752589821-145787-1-git-send-email-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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.
