+ *
+ * Hardware captures timestamps which contain only 32 bits of nominal
+ * nanoseconds, as opposed to the 64bit timestamps that the stack expects.
+ *
+ * Extend the 32bit nanosecond timestamp using the following algorithm and
+ * assumptions:
+ *
+ * 1) have a recently cached copy of the PHC time
+ * 2) assume that the in_tstamp was captured 2^31 nanoseconds (~2.1
+ * seconds) before or after the PHC time was captured.
+ * 3) calculate the delta between the cached time and the timestamp
+ * 4) if the delta is smaller than 2^31 nanoseconds, then the timestamp was
+ * captured after the PHC time. In this case, the full timestamp is just
+ * the cached PHC time plus the delta.
+ * 5) otherwise, if the delta is larger than 2^31 nanoseconds, then the
+ * timestamp was captured *before* the PHC time, i.e. because the PHC
+ * cache was updated after the timestamp was captured by hardware. In this
+ * case, the full timestamp is the cached time minus the inverse delta.
+ *
+ * This algorithm works even if the PHC time was updated after a Tx timestamp
+ * was requested, but before the Tx timestamp event was reported from

- * ice_cfg_fw_log - configure FW logging
- * @hw: pointer to the HW struct
- * @enable: enable certain FW logging events if true, disable all if false
- *
- * This function enables/disables the FW logging via Rx CQ events and a UART
- * port based on predetermined configurations. FW logging via the Rx CQ can be
- * enabled/disabled for individual PF's. However, FW logging via the UART can
- * only be enabled/disabled for all PFs on the same device.
- *
- * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
- * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
- * before initializing the device.
- *
- * When re/configuring FW logging, callers need to update the "cfg" elements of
- * the hw->fw_log.evnts array with the desired logging event configurations for
- * modules of interest. When disabling FW logging completely, the callers can
- * just pass false in the "enable" parameter. On completion, the function will
- * update the "cur" element of the hw->fw_log.evnts array with the resulting
- * logging event configurations of the modules that are being re/configured. FW
- * logging modules that are not part of a reconfiguration operation retain their
- * previous states.
- *
- * Before resetting the device, it is recommended that the driver disables FW
- * logging before shutting down the control queue. When disabling FW logging
- * ("enable" = false), the latest configurations of FW logging events stored in
- * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
- * a device reset.
- *
- * When enabling FW logging to emit log messages via the Rx CQ during the
- * device's initialization phase, a mechanism alternative to interrupt handlers
- * needs to be used to extract FW log messages from the Rx CQ periodically and
- * to prevent the Rx CQ from being full and stalling other types of control
- * messages from FW to SW. Interrupts are typically disabled during the device's
- * initialization phase.

+ * the current driver will not have to download the package again.
+ *
+ * The local package contents will be used to query default behavior and to
+ * update specific sections of the HW's version of the package (e.g. to update
+ * the parse graph to understand new protocols).
+ *
+ * This function stores a pointer to the package buffer memory, and it is
+ * expected that the supplied buffer will not be freed immediately. If the

+ *
+ * If a given index has a valid timestamp, perform the following steps:
+ *
+ * 1) check that the timestamp request is not stale
+ * 2) check that a timestamp is ready and available in the PHY memory bank
+ * 3) read and copy the timestamp out of the PHY register
+ * 4) unlock the index by clearing the associated in_use bit
+ * 5) check if the timestamp is stale, and discard if so
+ * 6) extend the 40 bit timestamp value to get a 64 bit timestamp value
+ * 7) send this 64 bit timestamp to the stack
+ *
+ * Note that we do not hold the tracking lock while reading the Tx timestamp.
+ * This is because reading the timestamp requires taking a mutex that might
+ * sleep.
+ *
+ * The only place where we set in_use is when a new timestamp is initiated
+ * with a slot index. This is only called in the hard xmit routine where an
+ * SKB has a request flag set. The only places where we clear this bit is this
+ * function, or during teardown when the Tx timestamp tracker is being
+ * removed. A timestamp index will never be re-used until the in_use bit for
+ * that index is cleared.
+ *
+ * If a Tx thread starts a new timestamp, we might not begin processing it
+ * right away but we will notice it at the end when we re-queue the task.
+ *
+ * If a Tx thread starts a new timestamp just after this function exits, the
+ * interrupt for that timestamp should re-trigger this function once
+ * a timestamp is ready.
+ *
+ * In cases where the PTP hardware clock was directly adjusted, some
+ * timestamps may not be able to safely use the timestamp extension math. In
+ * this case, software will set the stale bit for any outstanding Tx
+ * timestamps when the clock is adjusted. Then this function will discard
+ * those captured timestamps instead of sending them to the stack.
+ *
+ * If a Tx packet has been waiting for more than 2 seconds, it is not possible
+ * to correctly extend the timestamp using the cached PHC time. It is
+ * extremely unlikely that a packet will ever take this long to timestamp. If
+ * we detect a Tx timestamp request that has waited for this long we assume
+ * the packet will never be sent by hardware and discard it without reading
+ * the timestamp register.

- * ice_ptp_tx_tstamp_work - Process Tx timestamps for a port
- * @work: pointer to the kthread_work struct
- *
- * Process timestamps captured by the PHY associated with this port. To do
- * this, loop over each index with a waiting skb.
- *
- * If a given index has a valid timestamp, perform the following steps:
- *
- * 1) copy the timestamp out of the PHY register
- * 4) clear the timestamp valid bit in the PHY register
- * 5) unlock the index by clearing the associated in_use bit.
- * 2) extend the 40b timestamp value to get a 64bit timestamp
- * 3) send that timestamp to the stack
- *
- * After looping, if we still have waiting SKBs, then re-queue the work. This
- * may cause us effectively poll even when not strictly necessary. We do this
- * because it's possible a new timestamp was requested around the same time as
- * the interrupt. In some cases hardware might not interrupt us again when the
- * timestamp is captured.
- *
- * Note that we only take the tracking lock when clearing the bit and when
- * checking if we need to re-queue this task. The only place where bits can be
- * set is the hard xmit routine where an SKB has a request flag set. The only
- * places where we clear bits are this work function, or the periodic cleanup
- * thread. If the cleanup thread clears a bit we're processing we catch it
- * when we lock to clear the bit and then grab the SKB pointer. If a Tx thread
- * starts a new timestamp, we might not begin processing it right away but we
- * will notice it at the end when we re-queue the work item. If a Tx thread
- * starts a new timestamp just after this function exits without re-queuing,
- * the interrupt when the timestamp finishes should trigger. Avoiding holding
- * the lock for the entire function is important in order to ensure that Tx
- * threads do not get blocked while waiting for the lock.
