2022-11-22tsnep: Fix rotten packetsGerhard Engleder1-1/+56
If PTP synchronisation is done every second, then sporadic the interval is higher than one second: ptp4l[696.582]: master offset -17 s2 freq -1891 path delay 573 ptp4l[697.582]: master offset -22 s2 freq -1901 path delay 573 ptp4l[699.368]: master offset -1 s2 freq -1887 path delay 573 ^^^^^^^ Should be 698.582! This problem is caused by rotten packets, which are received after polling but before interrupts are enabled again. This can be fixed by checking for pending work and rescheduling if necessary after interrupts has been enabled again.

2022-11-22ice: fix handling of burst Tx timestampsJacob Keller2-16/+16
Commit 1229b33973c7 ("ice: Add low latency Tx timestamp read") refactored PTP timestamping logic to use a threaded IRQ instead of a separate kthread. This implementation introduced ice_misc_intr_thread_fn and redefined the ice_ptp_process_ts function interface to return a value of whether or not the timestamp processing was complete. ice_misc_intr_thread_fn would take the return value from ice_ptp_process_ts and convert it into either IRQ_HANDLED if there were no more timestamps to be processed, or IRQ_WAKE_THREAD if the thread should continue processing. This is not correct, as the kernel does not re-schedule threaded IRQ functions automatically. IRQ_WAKE_THREAD can only be used by the main IRQ function. This results in the ice_ptp_process_ts function (and in turn the ice_ptp_tx_tstamp function) from only being called exactly once per interrupt. If an application sends a burst of Tx timestamps without waiting for a response, the interrupt will trigger for the first timestamp. However, later timestamps may not have arrived yet. This can result in dropped or discarded timestamps. Worse, on E822 hardware this results in the interrupt logic getting stuck such that no future interrupts will be triggered. The result is complete loss of Tx timestamp functionality. Fix this by modifying the ice_misc_intr_thread_fn to perform its own polling of the ice_ptp_process_ts function. We sleep for a few microseconds between attempts to avoid wasting significant CPU time. The value was chosen to allow time for the Tx timestamps to complete without wasting so much time that we overrun application wait budgets in the worst case. The ice_ptp_process_ts function also currently returns false in the event that the Tx tracker is not initialized. This would result in the threaded IRQ handler never exiting if it gets started while the tracker is not initialized. Fix the function to appropriately return true when the tracker is not initialized. Note that this will not reproduce with default ptp4l behavior, as the program always synchronously waits for a timestamp response before sending another timestamp request.

2022-11-19iavf: Do not restart Tx queues after reset task failureIvan Vecera1-1/+15
After commit aa626da947e9 ("iavf: Detach device during reset task") the device is detached during reset task and re-attached at its end. The problem occurs when reset task fails because Tx queues are restarted during device re-attach and this leads later to a crash. To resolve this issue properly close the net device in cause of failure in reset task to avoid restarting of tx queues at the end. Also replace the hacky manipulation with IFF_UP flag by device close that clears properly both IFF_UP and __LINK_STATE_START flags. In these case iavf_close() does not do anything because the adapter state is already __IAVF_DOWN.

Recent commit aa626da947e9 ("iavf: Detach device during reset task") removed netif_tx_stop_all_queues() with an assumption that Tx queues are already stopped by netif_device_detach() in the beginning of reset task. This assumption is incorrect because during reset task a potential link event can start Tx queues again. Revert this change to fix this issue. Reproducer: 1.

You'd think people know that the internal 100BASE-TX PHY on the SJA1110 responds only to clause 22 MDIO transactions, but they don't :) When a clause 45 transaction is attempted, sja1105_base_tx_mdio_read() and sja1105_base_tx_mdio_write() don't expect "reg" to contain bit 30 set (MII_ADDR_C45) and pack this value into the SPI transaction buffer. But the field in the SPI buffer has a width smaller than 30 bits, so we see this confusing message from the packing() API rather than a proper rejection of C45 transactions: Call trace: dump_stack+0x1c/0x38 sja1105_pack+0xbc/0xc0 [sja1105] sja1105_xfer+0x114/0x2b0 [sja1105] sja1105_xfer_u32+0x44/0xf4 [sja1105] sja1105_base_tx_mdio_read+0x44/0x7c [sja1105] mdiobus_read+0x44/0x80 get_phy_c45_ids+0x70/0x234 get_phy_device+0x68/0x15c fwnode_mdiobus_register_phy+0x74/0x240 of_mdiobus_register+0x13c/0x380 sja1105_mdiobus_register+0x368/0x490 [sja1105] sja1105_setup+0x94/0x119c [sja1105] Cannot store 401d2405 inside bits 24-4 (would truncate) Fixes: 5a8f09748ee7 ("net: dsa: sja1105: register the MDIO buses for 100base-T1 and 100base-TX") Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

If at this point the external PHY is still initialising, no valid PHY ID will be read and on phy_find_first() the bind() function will fail.

2022-11-16platform/x86: ideapad-laptop: Fix interrupt storm on fn-lock toggle on some ↵Arnav Rawat1-0/+17
Yoga laptops Commit 3ae86d2d4704 ("platform/x86: ideapad-laptop: Fix Legion 5 Fn lock LED") uses the WMI event-id for the fn-lock event on some Legion 5 laptops to manually toggle the fn-lock LED because the EC does not do it itself. However, the same WMI ID is also sent on some Yoga laptops. Here, setting the fn-lock state is not valid behavior, and causes the EC to spam interrupts until the laptop is rebooted. Add a set_fn_lock_led_list[] DMI-id list and only enable the workaround to manually set the LED on models on this list.

Add device nodes to enable support for battery and charger status, the ACPI platform profile, as well as internal and type-cover HID devices (including sensors, touchpad, keyboard, and other miscellaneous devices) on the Surface Pro 9. This does not include support for a tablet-mode switch yet, as that is now handled via the POS subsystem (unlike the Surface Pro 8, where it is handled via the KIP subsystem) and therefore needs further changes. While we're at it, also add the missing comment for the Surface Pro 8.

2022-11-15platform/surface: aggregator: Do not check for repeated unsequenced packetsMaximilian Luz1-4/+20
Currently, we check any received packet whether we have already seen it previously, regardless of the packet type (sequenced / unsequenced). We do this by checking the sequence number. This assumes that sequence numbers are valid for both sequenced and unsequenced packets. However, this assumption appears to be incorrect. On some devices, the sequence number field of unsequenced packets (in particular HID input events on the Surface Pro 9) is always zero. As a result, the current retransmission check kicks in and discards all but the first unsequenced packet, breaking (among other things) keyboard and touchpad input. Note that we have, so far, only seen packets being retransmitted in sequenced communication. In particular, this happens when there is an ACK timeout, causing the EC (or us) to re-send the packet waiting for an ACK. Arguably, retransmission / duplication of unsequenced packets should not be an issue as there is no logical condition (such as an ACK timeout) to determine when a packet should be sent again. Therefore, remove the retransmission check for unsequenced packets entirely to resolve the issue.
