Currently, the debugfs command for fd tcam is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "fd_tcam" for it, and query it by command "cat fd_tcam", return the result to userspace, rather than record in dmesg. The display style is below: $ cat fd_tcam read result tcam key x(31): 00000000 00000000 00000000 08000000 00000600 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 read result tcam key y(31): 00000000 00000000 00000000 f7ff0000 0000f900 00000000 00000000 00000000 00000000 00000000 00000000 00000000 0000fff8 Signed-off-by: Hao Chen <chenhao288@hisilicon.com> Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> 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.
