2023-01-10igc: Fix PPS delta between two synchronized end-pointsChristopher S Hall2-4/+8
This patch fix the pulse per second output delta between two synchronized end-points. Based on Intel Discrete I225 Software User Manual Section 4.2.15 TimeSync Auxiliary Control Register, ST0[Bit 4] and ST1[Bit 7] must be set to ensure that clock output will be toggles based on frequency value defined. This is to ensure that output of the PPS is aligned with the clock. How to test: 1) Running time synchronization on both end points. Ex: ptp4l --step_threshold=1 -m -f gPTP.cfg -i <interface name> 2) Configure PPS output using below command for both end-points Ex: SDP0 on I225 REV4 SKU variant ./testptp -d /dev/ptp0 -L 0,2 ./testptp -d /dev/ptp0 -p 1000000000 3) Measure the output using analyzer for both end-points Fixes: 87938851b6ef ("igc: enable auxiliary PHC functions for the i225") Signed-off-by: Christopher S Hall <[email protected]> Signed-off-by: Muhammad Husaini Zulkifli <[email protected]> Acked-by: Sasha Neftin <[email protected]> Tested-by: Naama Meir <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>

The current code always does the accounting using the stats from the parent interface (linked in the rq). This doesn't work when there are child interfaces configured. Fix this behavior by always using the stats from the child interface priv. This will also work for parent only interfaces: the child (netdev) and parent netdev (rq->netdev) will point to the same thing.

2023-01-09net/mlx5e: IPoIB, Block PKEY interfaces with less rx queues than parentDragos Tatulea1-0/+9
A user is able to configure an arbitrary number of rx queues when creating an interface via netlink. This doesn't work for child PKEY interfaces because the child interface uses the parent receive channels. Although the child shares the parent's receive channels, the number of rx queues is important for the channel_stats array: the parent's rx channel index is used to access the child's channel_stats. So the array has to be at least as large as the parent's rx queue size for the counting to work correctly and to prevent out of bound accesses. This patch checks for the mentioned scenario and returns an error when trying to create the interface. The error is propagated to the user.

2023-01-09net/mlx5e: IPoIB, Block queue count configuration when sub interfaces are ↵Dragos Tatulea4-7/+62
present PKEY sub interfaces share the receive queues with the parent interface. While setting the sub interface queue count is not supported, it is currently possible to change the number of queues of the parent interface. Thus we can end up with inconsistent queue sizes between the parent and its sub interfaces. This change disallows setting the queue count on the parent interface when sub interfaces are present. This is achieved by introducing an explicit reference to the parent netdev in the mlx5i_priv of the child interface. An additional counter is also required on the parent side to detect when sub interfaces are attached and for proper cleanup. The rtnl lock is taken during the ethtool op and the sub interface ndo_init/uninit ops. There is no race here around counting the sub interfaces, reading the sub interfaces and setting the number of channels. The ASSERT_RTNL was added to document that.

2023-01-05net: ethernet: ti: am65-cpsw: Add support for SERDES configurationSiddharth Vadapalli2-0/+69
Use PHY framework APIs to initialize the SERDES PHY connected to CPSW MAC. Define the functions am65_cpsw_disable_phy(), am65_cpsw_enable_phy(), am65_cpsw_disable_serdes_phy() and am65_cpsw_enable_serdes_phy(). Add new member "serdes_phy" to struct "am65_cpsw_slave_data" to store the SERDES PHY for each port, if it exists. Use it later while disabling the SERDES PHY for each port. Power on and initialize the SerDes PHY in am65_cpsw_nuss_init_slave_ports() by invoking am65_cpsw_enable_serdes_phy(). Power off the SerDes PHY in am65_cpsw_nuss_remove() by invoking am65_cpsw_disable_serdes_phy(). Signed-off-by: Siddharth Vadapalli <[email protected]> Signed-off-by: Paolo Abeni <[email protected]>

2023-01-04qed: allow sleep in qed_mcp_trace_dump()Caleb Sander1-8/+20
By default, qed_mcp_cmd_and_union() delays 10us at a time in a loop that can run 500K times, so calls to qed_mcp_nvm_rd_cmd() may block the current thread for over 5s. We observed thread scheduling delays over 700ms in production, with stacktraces pointing to this code as the culprit. qed_mcp_trace_dump() is called from ethtool, so sleeping is permitted. It already can sleep in qed_mcp_halt(), which calls qed_mcp_cmd(). Add a "can sleep" parameter to qed_find_nvram_image() and qed_nvram_read() so they can sleep during qed_mcp_trace_dump(). qed_mcp_trace_get_meta_info() and qed_mcp_trace_read_meta(), called only by qed_mcp_trace_dump(), allow these functions to sleep. I can't tell if the other caller (qed_grc_dump_mcp_hw_dump()) can sleep, so keep b_can_sleep set to false when it calls these functions. An example stacktrace from a custom warning we added to the kernel showing a thread that has not scheduled despite long needing resched: [ 2745.362925,17] ------------[ cut here ]------------ [ 2745.362941,17] WARNING: CPU: 23 PID: 5640 at arch/x86/kernel/irq.c:233 do_IRQ+0x15e/0x1a0() [ 2745.362946,17] Thread not rescheduled for 744 ms after irq 99 [ 2745.362956,17] Modules linked in: ...

2023-01-03igc: Remove reset adapter task for i226 during disable tsn configMuhammad Husaini Zulkifli3-12/+7
I225 have limitation when programming the BaseTime register which required a power cycle of the controller. This limitation already lifted in I226. This patch removes the restriction so that when user configure/remove any TSN mode, it would not go into power cycle reset adapter. How to test: Schedule any gate control list configuration or delete it. Example: 1) BASE_TIME=$(date +%s%N) tc qdisc replace dev $interface_name parent root handle 100 taprio \ num_tc 4 \ map 3 1 0 2 3 3 3 3 3 3 3 3 3 3 3 3 \ queues 1@0 1@1 1@2 1@3 \ base-time $BASE_TIME \ sched-entry S 0F 1000000 \ flags 0x2 2) tc qdisc del dev $intername_name root Signed-off-by: Muhammad Husaini Zulkifli <[email protected]> Tested-by: Naama Meir <[email protected]> Signed-off-by: Tony Nguyen <[email protected]>

Make reset task only executes for i225 and Qbv disabling to allow i226 configure for 2nd GCL without resetting the adapter. In i226, Tx won't hang if there is a GCL is already running, so in this case we don't need to set FutScdDis bit.

2023-01-03igc: remove I226 Qbv BaseTime restrictionMuhammad Husaini Zulkifli5-16/+65
Remove the Qbv BaseTime restriction for I226 so that the BaseTime can be scheduled to the future time. A new register bit of Tx Qav Control (Bit-7: FutScdDis) was introduced to allow I226 scheduling future time as Qbv BaseTime and not having the Tx hang timeout issue. Besides, according to datasheet section 7.5.2.9.3.3, FutScdDis bit has to be configured first before the cycle time and base time. Indeed the FutScdDis bit is only active on re-configuration, thus we have to set the BASET_L to zero and then only set it to the desired value. Please also note that the Qbv configuration flow is moved around based on the Qbv programming guideline that is documented in the latest datasheet.
