Ido Schimmel says: ==================== mlxsw: Support for shared buffers in Spectrum-2 Petr says: Spectrum-2 will be configured with a different set of pools than Spectrum-1, their sizes will be larger, and the individual quotas will be different as well. It is therefore necessary to make the shared buffer module aware of this dependence on chip type, and adjust the individual tables. In patch #1, introduce a structure for keeping per-chip immutable and default values. In patch #2, structures for keeping current values of SBPM and SBPR (pool configuration and port-pool quota) are allocated dynamically to support varying pool counts. In patches #3 to #7, uses of individual shared buffer configuration tables are migrated from global definitions to fields in struct mlxsw_sp_sb_vals, which was introduced above. Up until this point, the actual configuration is still the one suitable for Spectrum-1. In patch #8 Spectrum-2 configuration is added. In patch #9, port headroom configuration is changed to take into account current recommended value for a 100-Gbps port, and the split factor. In patch #10, requests for overlarge headroom are rejected. This avoids potential chip freeze should such overlarge requests be made. ==================== Signed-off-by: David S.

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.
