Once packets are submitted to MDQ, hardware picks all active MDQs using strict priority, and MDQs having the same priority level are chosen using round robin. Each packet will traverse MDQ, TL4 to TL1 levels. Each level contains an array of queues to support scheduling and shaping. As HTB supports classful queuing mechanism by supporting rate and ceil and allow the user to control the absolute bandwidth to particular classes of traffic the same can be achieved by configuring shapers and schedulers on different transmit levels. This series of patches adds support for HTB offload, Patch1: Allow strict priority parameter in HTB offload mode. Patch2: Rename existing total tx queues for better readability Patch3: defines APIs such that the driver can dynamically initialize/ deinitialize the send queues. Patch4: Refactors transmit alloc/free calls as preparation for QOS offload code. Patch5: Adds actual HTB offload support. Patch6: Add documentation about htb offload flow in driver Hariprasad Kelam (3): octeontx2-pf: Rename tot_tx_queues to non_qos_queues octeontx2-pf: Refactor schedular queue alloc/free calls docs: octeontx2: Add Documentation for QOS Naveen Mamindlapalli (2): sch_htb: Allow HTB priority parameter in offload mode octeontx2-pf: Add support for HTB offload Subbaraya Sundeep (1): octeontx2-pf: qos send queues management ----- v1 -> v2 : ensure other drivers won't affect by allowing 'prio' a parameter in htb offload mode. v2 -> v3 : 1. discard patch supporting devlink to configure TL1 round robin priority 2. replace NL_SET_ERR_MSG with NL_SET_ERR_MSG_MOD 3. use max3 instead of using max couple of times and use a better naming convention in send queue management code. v3 -> v4: 1. fix sparse warnings. 2. release mutex lock in error conditions. v4 -> v5: 1. fix pahole reported issues 2. add documentation for htb offload flow. v5 -> v6: 1. fix synchronization issues w.r.t hlist accessing from ndo_select_queue with rcu lock. 2. initialize qos related resources in device init. .../ethernet/marvell/octeontx2.rst | 39 + .../ethernet/marvell/octeontx2/af/common.h | 2 +- .../marvell/octeontx2/af/rvu_debugfs.c | 5 + .../ethernet/marvell/octeontx2/af/rvu_nix.c | 45 + .../ethernet/marvell/octeontx2/nic/Makefile | 2 +- .../marvell/octeontx2/nic/otx2_common.c | 120 +- .../marvell/octeontx2/nic/otx2_common.h | 53 +- .../marvell/octeontx2/nic/otx2_ethtool.c | 31 +- .../ethernet/marvell/octeontx2/nic/otx2_pf.c | 114 +- .../ethernet/marvell/octeontx2/nic/otx2_reg.h | 13 + .../ethernet/marvell/octeontx2/nic/otx2_tc.c | 7 +- .../marvell/octeontx2/nic/otx2_txrx.c | 24 +- .../marvell/octeontx2/nic/otx2_txrx.h | 3 +- .../ethernet/marvell/octeontx2/nic/otx2_vf.c | 14 +- .../net/ethernet/marvell/octeontx2/nic/qos.c | 1469 +++++++++++++++++ .../net/ethernet/marvell/octeontx2/nic/qos.h | 69 + .../ethernet/marvell/octeontx2/nic/qos_sq.c | 296 ++++ .../net/ethernet/mellanox/mlx5/core/en/qos.c | 7 +- include/net/pkt_cls.h | 1 + net/sched/sch_htb.c | 7 +- 20 files changed, 2216 insertions(+), 105 deletions(-) create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/qos.c create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/qos.h create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/qos_sq.c --- 2.17.1
