net: hns3: refactor queue info of debugfs
mainline inclusion from mainline-master commit e44c495d category: feature bugzilla: 173966 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e44c495d95e0dd3a5513f72a830639a72b4c14f1 ---------------------------------------------------------------------- Currently, the debugfs command for queue info is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create two files "rx_queue_info" and "tx_queue_info" for it, and query it by command "cat rx_queue_info" and "cat tx_queue_info", return the result to userspace, rather than record in dmesg. The display style is below: $ cat rx_queue_info QUEUE_ID BD_NUM BD_LEN TAIL HEAD FBDNUM PKTNUM ... 0 0 0 0 0 0 0 ... 1 0 0 0 0 0 0 ... 2 0 0 0 0 0 0 ... $ cat tx_queue_info QUEUE_ID BD_NUM TC TAIL HEAD FBDNUM OFFSET PKTNUM ... 0 0 0 0 0 0 0 0 ... 1 0 0 0 0 0 0 0 ... 2 0 0 0 0 0 0 0 ...
