Choong Yong Liang says: ==================== Enable SGMII and 2500BASEX interface mode switching for Intel platforms During the interface mode change, the 'phylink_major_config' function will be triggered in phylink. The modification of the following functions will support the switching between SGMII and 2500BASE-X interface modes for the Intel platform: - xpcs_switch_interface_mode: Re-initiates clause 37 auto-negotiation for the SGMII interface mode to perform auto-negotiation. - mac_finish: Configures the SerDes according to the interface mode. With the above changes, the code will work as follows during the interface mode change. The PCS will reconfigure according to the pcs_neg_mode and the selected interface mode. Then, the MAC driver will perform SerDes configuration in 'mac_finish' based on the selected interface mode. During the SerDes configuration, the selected interface mode will identify TSN lane registers from FIA and then send IPC commands to the Power Management Controller (PMC) through the PMC driver/API. The PMC will act as a proxy to program the PLL registers. ==================== Link: https://patch.msgid.link/20250227121522.1802832-1-yong.liang.choong@linux.intel.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.
