The following changes since commit 2f0968a030f2a5dd4897a0151c8395bf5babe5b0: net: gso_test: fix build with gcc-12 and earlier (2023-10-12 15:34:08 +0200) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux.git tags/mlx5-updates-2023-10-10 for you to fetch changes up to 8c18eaea290b1f4d9fc784703aaec3b3cdb7eab9: net/mlx5e: Allow IPsec soft/hard limits in bytes (2023-10-12 12:19:17 -0700) ---------------------------------------------------------------- mlx5-updates-2023-10-10 1) Adham Faris, Increase max supported channels number to 256 2) Leon Romanovsky, Allow IPsec soft/hard limits in bytes 3) Shay Drory, Replace global mlx5_intf_lock with HCA devcom component lock 4) Wei Zhang, Optimize SF creation flow During SF creation, HCA state gets changed from INVALID to IN_USE step by step. Accordingly, FW sends vhca event to driver to inform about this state change asynchronously. Each vhca event is critical because all related SW/FW operations are triggered by it. Currently there is only a single mlx5 general event handler which not only handles vhca event but many other events. This incurs huge bottleneck because all events are forced to be handled in serial manner. Moreover, all SFs share same table_lock which inevitably impacts each other when they are created in parallel. This series will solve this issue by: 1. A dedicated vhca event handler is introduced to eliminate the mutual impact with other mlx5 events. 2. Max FW threads work queues are employed in the vhca event handler to fully utilize FW capability. 3. Redesign SF active work logic to completely remove table_lock. With above optimization, SF creation time is reduced by 25%, i.e. from 80s to 60s when creating 100 SFs. Patches summary: Patch 1 - implement dedicated vhca event handler with max FW cmd threads of work queues. Patch 2 - remove table_lock by redesigning SF active work logic. ---------------------------------------------------------------- Adham Faris (5): net/mlx5e: Refactor rx_res_init() and rx_res_free() APIs net/mlx5e: Refactor mlx5e_rss_set_rxfh() and mlx5e_rss_get_rxfh() net/mlx5e: Refactor mlx5e_rss_init() and mlx5e_rss_free() API's net/mlx5e: Preparations for supporting larger number of channels net/mlx5e: Increase max supported channels number to 256 Jinjie Ruan (1): net/mlx5: Use PTR_ERR_OR_ZERO() to simplify code Leon Romanovsky (1): net/mlx5e: Allow IPsec soft/hard limits in bytes Lukas Bulwahn (1): net/mlx5: fix config name in Kconfig parameter documentation Shay Drory (3): net/mlx5: Avoid false positive lockdep warning by adding lock_class_key net/mlx5: Refactor LAG peer device lookout bus logic to mlx5 devcom net/mlx5: Replace global mlx5_intf_lock with HCA devcom component lock Wei Zhang (2): net/mlx5: Parallelize vhca event handling net/mlx5: Redesign SF active work to remove table_lock Yu Liao (1): net/mlx5e: Use PTR_ERR_OR_ZERO() to simplify code Yue Haibing (1): net/mlx5: Remove unused declaration .../ethernet/mellanox/mlx5/kconfig.rst | 2 +- drivers/net/ethernet/mellanox/mlx5/core/dev.c | 105 ++------------- drivers/net/ethernet/mellanox/mlx5/core/en.h | 5 +- drivers/net/ethernet/mellanox/mlx5/core/en/fs.h | 1 - drivers/net/ethernet/mellanox/mlx5/core/en/rqt.c | 32 +++-- drivers/net/ethernet/mellanox/mlx5/core/en/rqt.h | 9 +- drivers/net/ethernet/mellanox/mlx5/core/en/rss.c | 144 ++++++++++++++++----- drivers/net/ethernet/mellanox/mlx5/core/en/rss.h | 20 ++- .../net/ethernet/mellanox/mlx5/core/en/rx_res.c | 105 ++++++++------- .../net/ethernet/mellanox/mlx5/core/en/rx_res.h | 12 +- .../ethernet/mellanox/mlx5/core/en_accel/ipsec.c | 23 ++-- .../mellanox/mlx5/core/en_accel/ipsec_fs.c | 24 ++-- .../mellanox/mlx5/core/en_accel/ipsec_rxtx.h | 1 - .../net/ethernet/mellanox/mlx5/core/en_ethtool.c | 2 +- drivers/net/ethernet/mellanox/mlx5/core/en_fs.c | 8 +- drivers/net/ethernet/mellanox/mlx5/core/en_main.c | 32 ++--- drivers/net/ethernet/mellanox/mlx5/core/en_rep.c | 27 ++-- drivers/net/ethernet/mellanox/mlx5/core/en_tc.c | 16 ++- drivers/net/ethernet/mellanox/mlx5/core/events.c | 5 - .../net/ethernet/mellanox/mlx5/core/ipoib/ipoib.c | 24 ++-- drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c | 47 +++++-- drivers/net/ethernet/mellanox/mlx5/core/lag/lag.h | 1 + .../net/ethernet/mellanox/mlx5/core/lag/mpesw.c | 9 +- .../net/ethernet/mellanox/mlx5/core/lag/port_sel.c | 10 +- .../net/ethernet/mellanox/mlx5/core/lib/devcom.c | 25 ++++ .../net/ethernet/mellanox/mlx5/core/lib/devcom.h | 5 + drivers/net/ethernet/mellanox/mlx5/core/lib/eq.h | 1 - drivers/net/ethernet/mellanox/mlx5/core/main.c | 25 ++++ .../net/ethernet/mellanox/mlx5/core/mlx5_core.h | 14 +- .../net/ethernet/mellanox/mlx5/core/sf/dev/dev.c | 86 +++++++----- .../ethernet/mellanox/mlx5/core/sf/vhca_event.c | 69 +++++++++- .../ethernet/mellanox/mlx5/core/sf/vhca_event.h | 3 + .../mellanox/mlx5/core/steering/dr_types.h | 4 - include/linux/mlx5/driver.h | 16 +-- 34 files changed, 544 insertions(+), 368 deletions(-)
