2023-01-18net/mlx5: Add hardware extended range support for PTP adjtime and adjphaseRahul Rameshbabu
Capable hardware can use an extended range for offsetting the clock. An extended range of [-200000,200000] is used instead of [-32768,32767] for the delta/phase parameter of the adjtime/adjphase ptp_clock_info callbacks.

2023-01-18net/mlx5: Add adjphase function to support hardware-only offset controlRahul Rameshbabu
The adjtime function supports using hardware to set the clock offset when the delta was supported by the hardware. When the delta is not supported by the hardware, the driver handles adjusting the clock. The newly-introduced adjphase function is similar to the adjtime function, except it guarantees that a provided clock offset will be used directly by the hardware to adjust the PTP clock. When the range is not acceptable by the hardware, an error is returned.

Suppress error logging that can be triggered by userspace upon DEVX UCTX creation. The reason that it's not suppressed today with the uid check to suppress DEVX is that MLX5_CMD_OP_CREATE_UCTX command still doesn't have a uid as it comes to create it..

Steen Hegelund says: ==================== sparx5: Improve locking in the VCAP API This improves the VCAP cache and the VCAP rule list protection against access from different sources. The VCAP Admin lock protects the list of rules for the VCAP instance as well as the cache used for encoding and decoding rules. This series provides dedicated functions for accessing rule statistics, decoding rule content, verifying if a rule exists and getting a rule with the lock held, as well as ensuring the use of the lock when the list of rules or the cache is accessed. ==================== Signed-off-by: David S.

2023-01-18gpiolib: acpi: Add a ignore wakeup quirk for Clevo NL5xRUMario Limonciello
commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable") changed the policy such that I2C touchpads may be able to wake up the system by default if the system is configured as such. However on Clevo NL5xRU there is a mistake in the ACPI tables that the TP_ATTN# signal connected to GPIO 9 is configured as ActiveLow and level triggered but connected to a pull up. As soon as the system suspends the touchpad loses power and then the system wakes up. To avoid this problem, introduce a quirk for this model that will prevent the wakeup capability for being set for GPIO 9.

2023-01-18virtio-net: correctly enable callback during start_xmitJason Wang
Commit a7766ef18b33("virtio_net: disable cb aggressively") enables virtqueue callback via the following statement: do { if (use_napi) virtqueue_disable_cb(sq->vq); free_old_xmit_skbs(sq, false); } while (use_napi && kick && unlikely(!virtqueue_enable_cb_delayed(sq->vq))); When NAPI is used and kick is false, the callback won't be enabled here. And when the virtqueue is about to be full, the tx will be disabled, but we still don't enable tx interrupt which will cause a TX hang. This could be observed when using pktgen with burst enabled. TO be consistent with the logic that tries to disable cb only for NAPI, fixing this by trying to enable delayed callback only when NAPI is enabled when the queue is about to be full.

2023-01-18net: macb: simplify TX timestamp handlingRobert Hancock
This driver was capturing the TX timestamp values from the TX ring during the TX completion path, but deferring the actual packet TX timestamp updating to a workqueue. There does not seem to be much of a reason for this with the current state of the driver. Simplify this to just do the TX timestamping as part of the TX completion path, to avoid the need for the extra timestamp buffer and workqueue.

2023-01-18net: macb: fix PTP TX timestamp failure due to packet paddingRobert Hancock
PTP TX timestamp handling was observed to be broken with this driver when using the raw Layer 2 PTP encapsulation. ptp4l was not receiving the expected TX timestamp after transmitting a packet, causing it to enter a failure state. The problem appears to be due to the way that the driver pads packets which are smaller than the Ethernet minimum of 60 bytes. If headroom space was available in the SKB, this caused the driver to move the data back to utilize it. However, this appears to cause other data references in the SKB to become inconsistent. In particular, this caused the ptp_one_step_sync function to later (in the TX completion path) falsely detect the packet as a one-step SYNC packet, even when it was not, which caused the TX timestamp to not be processed when it should be. Using the headroom for this purpose seems like an unnecessary complexity as this is not a hot path in the driver, and in most cases it appears that there is sufficient tailroom to not require using the headroom anyway. Remove this usage of headroom to prevent this inconsistency from occurring and causing other problems.
