mainline inclusion from mainline-master commit 7679f28e category: feature bugzilla: 173966 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7679f28e32a48461be4d4c30c14d7be06300cd5d ---------------------------------------------------------------------- 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: NGuangbin Huang <huangguangbin2@huawei.com> Signed-off-by: NHuazhong Tan <tanhuazhong@huawei.com> Signed-off-by: NDavid S.
