* ionic: add support for ethtool extended stat link_down_countNitya Sunkad2023-06-123-0/+12
| | | | | | | | | | | | | | | | Following the example of 'commit 9a0f830f8026 ("ethtool: linkstate: add a statistic for PHY down events")', added support for link down events. Add callback ionic_get_link_ext_stats to ionic_ethtool.c to support link_down_count, a property of netdev that gets reported exclusively on physical link down events. Run ethtool -I <devname> to display the device link down count. Signed-off-by: Nitya Sunkad <nitya.sunkad@amd.com> Signed-off-by: Shannon Nelson <shannon.nelson@amd.com> Signed-off-by: David S.

First, a new custom enumerated return value is used instead of a boolean for ice_ptp_process_ts(). This significantly reduces the cognitive burden when reviewing the logic for this function, as the expected action is clear from the return value name. Second, the unconditional loop in ice_misc_intr_thread_fn() is removed, replacing it with a write to the Other Interrupt Cause register. This causes the MAC to trigger the Tx timestamp interrupt again. This makes it possible to safely use the ice_misc_intr_thread_fn() to handle other tasks beyond just the Tx timestamps. It is also easier to reason about since the thread function will exit cleanly if we do something like disable the interrupt and call synchronize_irq(). Third, refactor the handling for external timestamp events to use the miscellaneous thread function. This resolves an issue with the external time stamps getting blocked while processing the periodic work function task. Fourth, a simplification of the ice_misc_intr() function to always return IRQ_WAKE_THREAD, and schedule the ice service task in the ice_misc_intr_thread_fn() instead. Finally, the Other Interrupt Cause is kept disabled over the thread function processing, rather than immediately re-enabled. Special thanks to Michal Schmidt for the careful review of the series and pointing out my misunderstandings of the kernel IRQ code. It has been determined that the race outlined as being fixed in previous series was actually introduced by this series itself, which I've since corrected. ==================== Signed-off-by: David S.

| * ice: do not re-enable miscellaneous interrupt until thread_fn completesJacob Keller2023-06-081-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ice driver uses threaded IRQ for managing Tx timestamps via the devm_request_threaded_irq() interface. The ice_misc_intr() handler function is responsible for processing the hard interrupt context, and can wake the ice_misc_intr_thread_fn() by returning IRQ_WAKE_THREAD. The request_threaded_irq() function comment says: @handler is still called in hard interrupt context and has to check whether the interrupt originates from the device. If yes, it needs to disable the interrupt on the device and return IRQ_WAKE_THREAD which will wake up the handler thread and run the @thread_fn. We currently re-enable the Other Interrupt Cause Register (OCIR) at the end of ice_misc_intr(). In practice, this seems to be ok, but it can make communicating between the handler function and the thread function difficult. This is because the interrupt can trigger again while the thread function is still processing. Move the OICR update to the end of the thread function, leaving the other interrupt cause disabled in hardware until we complete one pass of the thread function. This prevents the miscellaneous interrupt from firing until after we finish the thread function.

| * ice: trigger PFINT_OICR_TSYN_TX interrupt instead of pollingJacob Keller2023-06-081-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In ice_misc_intr_thread_fn(), if we do not complete all Tx timestamp work, the thread function will poll continuously forever. For E822 hardware, this wastes time as the return value from ice_ptp_process_ts() is accurate and always reports correctly that the PHY actually has new timestamp data. In addition, if we receive enough timestamps with the right pacing, we may never exit this polling. Should this occur, other tasks handled by the ice_misc_intr_thread_fn() will never be processed. Fix this by instead writing to PFINT_OICR, causing an emulated interrupt to be triggered immediately. This does take slightly more processing than just re-checking the timestamps. However, it allows all of the other interrupt causes a chance to be processed first in the hard IRQ function. Note that the OICR interrupt is configured to be throttled to no more than once every 124 microseconds. This gives an effective interrupt rate of ~8000 interrupts per second. This should thus not cause a significant increase in overall CPU usage when compared to sleeping.

| * ice: introduce ICE_TX_TSTAMP_WORK enumerationJacob Keller2023-06-083-22/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ice_ptp_process_ts() function and its various helper functions return a boolean value indicating whether any work is remaining. This use of a boolean has grown confusing as we have multiple helpers that pass status between each other. Readers must be aware of what "true" and "false" mean, and it is very easy to get their meaning inverted. The names of the functions are not standard "yes/no" questions, which is the best practice for boolean returns. Replace this use of an enumeration with a custom type, enum ice_tx_tstamp_work. This enumeration clearly indicates whether all work is done, or if more work is pending. To aid in readability, factor the actual list iteration and processing out into ice_ptp_process_tx_tstamp(), making it void. Then call this in ice_ptp_tx_tstamp() ensuring that we always check the Tracker list at the end when determining the appropriate return value. Now the return value is an explicit name instead of the true or false value. This is easier to follow and makes reading the resulting callers much simpler. In addition, this paves the way for future work to allow E822 hardware to process timestamps for all functions using a single interrupt on the clock owning PF.

| * ice: handle extts in the miscellaneous interrupt threadKarol Kolacinski2023-06-084-19/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ice_ptp_extts_work() and ice_ptp_periodic_work() functions are both scheduled on the same kthread worker, pf.ptp.kworker. The ice_ptp_periodic_work() function sends to the firmware to interact with the PHY, and must block to wait for responses. This can cause delay in responding to the PFINT_OICR_TSYN_EVNT interrupt cause, ultimately resulting in disruption to processing an input signal of the frequency is high enough. In our testing, even 100 Hz signals get disrupted. Fix this by instead processing the signal inside the miscellaneous interrupt thread prior to handling Tx timestamps. Use atomic bits in a new pf->misc_thread bitmap in order to safely communicate which tasks require processing within the ice_misc_intr_thread_fn(). This ensures the communication of desired tasks from the ice_misc_intr() are correctly processed without racing even in the event that the interrupt triggers again before the thread function exits.

In this case, we still offload the flow rule, but with its action-set-list ID pointing at a "fallback" action which simply delivers the packet to its default destination (as though no flow rule had matched), thus allowing software TC to handle it. Later, when we receive a neighbouring update that allows us to construct the encap header, the rule will become "ready" and we will update its action-set-list ID in hardware to point at the actual offloaded actions.

The warning is valid, as during normal operation the rsi_config_wowlan() should only ever be called with non-NULL wowlan_config. In shutdown this rsi_config_wowlan() should only ever be called if WoWlan was configured before by the user. Add checks for non-NULL wowlan_config into the shutdown hook.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In brcmf_chip_recognition(), the return value from an MMIO read is interpreted as various fields without checking if it failed, which is harmless today, as the interpreted fields are checked for validity a few lines below. However, in corner cases (on my MacbookPro 14,1, sometimes after waking from sleep or soft reboot), when this happens, it causes the logging to be misleading, because the message indicates an unsupported chip type ("brcmfmac: brcmf_chip_recognition: chip backplane type 15 is not supported"). This patch detects this case slightly earlier and logs an appropriate message, with the same return result as is the case today.

Before entity is active, we restrict TX power from being set by outside callers, e.g. SAR/regulatory. We mark entity as inactive when powering off MAC. Then, we will mark it as active when we initialize HW channel stuffs after MAC power on. Although we can get an active entity after leaving idle phase, TX power doesn't be set well for default channel until stack set target channel for connection. It causes that RF things cannot use better TX power during this interval. Below are some cases which may encounter this or a similar situation. * hw scan process before connection As described above. * right after restart hardware process (SER L2) HW stuffs of target channel is initialized after mac80211 restart hardware, but we unexpectedly need to wait one more command to set channel again or to set TX power. To fix it and improve RF behavior in that interval, during setting channel, we don't need to check entity state before setting TX power, which actually is used to restrict outside callers. It means we call chip ops directly to replace the wrapper call. Then, TX power can be initialized as long as we initialize/setup HW stuffs on one channel. Besides, all chips should configure ops of setting TX power, so we remove trivial check on pointer.
