The next patch will add the ability to share nexthop counters among mlxsw nexthops backed by the same core nexthop. To have a place to store reference count, the counter should be kept in a dedicated structure. In this patch, introduce the structure together with the related helpers, sans the refcount, which comes in the next patch. Signed-off-by:

mlxsw_sp_nexthop_counter_disable() decays to a nop when called on a disabled counter, but mlxsw_sp_nexthop_counter_enable() can't similarly be called on an enabled counter. This would be useful in the following patches. Add the missing condition. Signed-off-by:

For the report_delta-like interface like a previous patch has added for collection of NH group statistics, it's easiest to read the counter and have the HW clear it right away. Thus, change mlxsw_sp_flow_counter_get() to take a bool indicating whether this should be done. Signed-off-by:

The function mlxsw_sp_nexthop_counter_alloc() doesn't directly allocate anything, and mlxsw_sp_nexthop_counter_free() doesn't directly free. For the following patches, we will need names for functions that actually do those things. Therefore rename to mlxsw_sp_nexthop_counter_enable() and mlxsw_sp_nexthop_counter_disable() to free up the namespace. Signed-off-by:

When sending the notifications to collect NH statistics for resilient groups, the driver will need to know the nexthop IDs in individual buckets to look up the right counter. To that end, move the nexthop ID from struct nh_notifier_grp_entry_info to nh_notifier_single_info. Signed-off-by:

The NEXTHOP_EVENT_RES_TABLE_PRE_REPLACE notifier currently keeps the group ID unset. That makes it impossible to look up the group for which the notifier is intended. This is not an issue at the moment, because the only client is netdevsim, and that just so that it veto replacements, which is a static property not tied to a particular group. But for any practical use, the ID is necessary. Set it. Signed-off-by:

Add a space (' ') prefix to every userdata line to match docs for dev-kmsg. To account for this extra character in each userdata entry, reduce userdata entry names (directory name) from 54 characters to 53.

Handling case err == 0 in the other branch allows to simplify the code. In addition I assume in "err & phydev->eee_cfg.tx_lpi_enabled" it should have been a logical and operator. It works as expected also with the bitwise and, but using a bitwise and with a bool value looks ugly to me. Signed-off-by:

Disable LEDs just before resetting the MT7530 to avoid situations where the ESW_P4_LED_0 and ESW_P3_LED_0 pin states may cause an unintended external crystal frequency to be selected. The HT_XTAL_FSEL (External Crystal Frequency Selection) field of HWTRAP (the Hardware Trap register) stores a 2-bit value that represents the state of the ESW_P4_LED_0 and ESW_P4_LED_0 pins (seemingly) sampled just after the MT7530 has been reset, as: ESW_P4_LED_0 ESW_P3_LED_0 Frequency ----------------------------------------- 0 1 20MHz 1 0 40MHz 1 1 25MHz The value of HT_XTAL_FSEL is bootstrapped by pulling ESW_P4_LED_0 and ESW_P3_LED_0 up or down accordingly, but: if a 40MHz crystal has been selected and the ESW_P3_LED_0 pin is high during reset, or a 20MHz crystal has been selected and the ESW_P4_LED_0 pin is high during reset, then the value of HT_XTAL_FSEL will indicate that a 25MHz crystal is present. By default, the state of the LED pins is PHY controlled to reflect the link state. To illustrate, if a board has: 5 ports with active low LED control, and HT_XTAL_FSEL bootstrapped for 40MHz. When the MT7530 is powered up without any external connection, only the LED associated with Port 3 is illuminated as ESW_P3_LED_0 is low. In this state, directly after mt7530_setup()'s reset is performed, the HWTRAP register (0x7800) reflects the intended HT_XTAL_FSEL (HWTRAP bits 10:9) of 40MHz: mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007dcf >>> bin(0x7dcf >> 9 & 0b11) '0b10' But if a cable is connected to Port 3 and the link is active before mt7530_setup()'s reset takes place, then HT_XTAL_FSEL seems to be set for 25MHz: mt7530-mdio mdio-bus:1f: mt7530_read: 00007800 == 00007fcf >>> bin(0x7fcf >> 9 & 0b11) '0b11' Once HT_XTAL_FSEL reflects 25MHz, none of the ports are functional until the MT7621 (or MT7530 itself) is reset. By disabling the LED pins just before reset, the chance of an unintended HT_XTAL_FSEL value is reduced.

Running the page-pool sample on production machines under moderate networking load shows recycling rate higher than 100%: $ page-pool eth0[2] page pools: 14 (zombies: 0) refs: 89088 bytes: 364904448 (refs: 0 bytes: 0) recycling: 100.3% (alloc: 1392:2290247724 recycle: 469289484:1828235386) Note that outstanding refs (89088) == slow alloc * cache size (1392 * 64) which means this machine is recycling page pool pages perfectly, not a single page has been released. The extra 0.3% is because sample ignores allocations from the ptr_ring. Treat those the same as alloc_fast, the ring vs cache alloc is already captured accurately enough by recycling stats. With the fix: $ page-pool eth0[2] page pools: 14 (zombies: 0) refs: 89088 bytes: 364904448 (refs: 0 bytes: 0) recycling: 100.0% (alloc: 1392:2331141604 recycle: 473625579:1857460661) Signed-off-by: -

Saeed Mahameed says: ==================== Support Multi-PF netdev (Socket Direct) This series adds support for combining multiple devices (PFs) of the same port under one netdev instance. Passing traffic through different devices belonging to different NUMA sockets saves cross-numa traffic and allows apps running on the same netdev from different numas to still feel a sense of proximity to the device and achieve improved performance. We achieve this by grouping PFs together, and creating the netdev only once all group members are probed. Symmetrically, we destroy the netdev once any of the PFs is removed. The channels are distributed between all devices, a proper configuration would utilize the correct close numa when working on a certain app/cpu. We pick one device to be a primary (leader), and it fills a special role. The other devices (secondaries) are disconnected from the network in the chip level (set to silent mode). All RX/TX traffic is steered through the primary to/from the secondaries. Currently, we limit the support to PFs only, and up to two devices (sockets). * tag 'mlx5-socket-direct-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: Documentation: networking: Add description for multi-pf netdev net/mlx5: Enable SD feature net/mlx5e: Block TLS device offload on combined SD netdev net/mlx5e: Support per-mdev queue counter net/mlx5e: Support cross-vhca RSS net/mlx5e: Let channels be SD-aware net/mlx5e: Create EN core HW resources for all secondary devices net/mlx5e: Create single netdev per SD group net/mlx5: SD, Add debugfs net/mlx5: SD, Add informative prints in kernel log net/mlx5: SD, Implement steering for primary and secondaries net/mlx5: SD, Implement devcom communication and primary election net/mlx5: SD, Implement basic query and instantiation net/mlx5: SD, Introduce SD lib net/mlx5: Add MPIR bit in mcam_access_reg ==================== Link: https://lore.kernel.org/r/20240307084229.500776-1-saeed@kernel.orgSigned-off-by:
