Currently, the debugfs command for tm map is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "tm_map" for it, and query it by command "cat tm_map", return the result to userspace, rather than record in dmesg. As user can't specify queue id in cat command, driver will return info of all queue id. The display style is below: $ cat tm_map queue_id qset_id pri_id tc_id 0000 0000 00 00 INDEX | TM BP QSET MAPPING: 0000 | 00000000:00000000:00000000:00000000:00000000:00000000:00000000 0256 | 00000000:00000000:00000000:00000000:00000000:00000002:00000000 0512 | 00000000:00000000:00000000:00000004:00000000:00000000:00000000 0768 | 00000000:00000008:00000000:00000000:00000000:00000000:00000000 Signed-off-by: Guangbin Huang <huangguangbin2@huawei.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.
