Linux kernel source tree
39c1202fa9
As a specific function (mdev) is chosen to send MTPPSE command to firmware, the event is generated only on that function. When that function is unloaded, the PPS event can't be forward to PTP device, even when there are other functions in the group, and PTP device is not destroyed. To resolve this problem, need to send MTPPSE again from new function, and dis-arm the event on old function after that. PPS events are handled by EQ notifier. The async EQs and notifiers are destroyed in mlx5_eq_table_destroy() which is called before mlx5_cleanup_clock(). During the period between mlx5_eq_table_destroy() and mlx5_cleanup_clock(), the events can't be handled. To avoid event loss, add mlx5_clock_unload() in mlx5_unload() to arm the event on other available function, and mlx5_clock_load in mlx5_load() for symmetry.

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.
