Linux kernel source tree
e2fb373038
Unlike earlier silicon variants, OcteonTx2 98xx silicon has 2 NIX blocks and each of the CGX is mapped to either of the NIX blocks. Each NIX block supports 100G. Mapping btw NIX blocks and CGX is done by firmware based on CGX speed config to have a maximum possible network bandwidth. Since the mapping is not fixed, it's difficult for a user to figure out. Hence added a debugfs entry which displays mapping between CGX LMAC, NIX block and RVU PF. Sample result of this entry :: ~# cat /sys/kernel/debug/octeontx2/rvu_pf_cgx_map PCI dev RVU PF Func NIX block CGX LMAC 0002:02:00.0 0x400 NIX0 CGX0 LMAC0 Signed-off-by: Rakesh Babu <rsaladi2@marvell.com> Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: Subbaraya Sundeep <sbhatta@marvell.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 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.
