Second, the +GPEs without these methods (like GPEs listed by _PRW objects for +wakeup devices) need to be enabled directly by the code that is +going to use them (e.g. ACPI power management or device drivers). + +In the former case, if the status of a given GPE is set to start +with, its handler method (either _Lxx or _Exx) needs to be invoked +to take care of the events (possibly) signaled before the GPE was +enabled. In the latter case, however, the first caller of +acpi_enable_gpe() for a given GPE should not be expected to care +about any events that might be signaled through it earlier. In +that case, it is better to clear the status of the GPE before +enabling it, to prevent stale events from triggering unwanted +actions (like spurious system resume, for example). + +For this reason, modify acpi_ev_add_gpe_reference() to take an +additional boolean argument indicating whether or not the GPE +status needs to be cleared when its reference counter changes from +zero to one and make acpi_enable_gpe() pass TRUE to it through +that new argument. + +Fixes: 18996f2db918 ("ACPICA: Events: Stop unconditionally clearing ACPI IRQs during suspend/resume") +Reported-by: Furquan Shaikh +Tested-by: Furquan Shaikh +Tested-by: Mika Westerberg +Signed-off-by: Rafael J.

In the event +that the remote side requests to change the connection interval, the Linux +kernel currently only validates that the desired value is within the +acceptable range in the Bluetooth specification (6 - 3200, corresponding to +7.5ms - 4000ms). There is currently no validation that the desired value +requested by the remote device is within the min/max limits specified in +the conn_min_interval/conn_max_interval configurations.

If the desired value is outside of the +current connection min/max values, then the connection parameter update +request is rejected and the negative response is returned to the remote +device. Recall that the initial connection is established using the local +conn_min_interval/conn_max_interval values, so this allows the Linux +administrator to retain control over the BLE connection interval. + +The one downside that I see is that the current default Linux values for +conn_min_interval and conn_max_interval typically correspond to 30ms and +50ms respectively. If this change were accepted, then it is feasible that +some devices would no longer be able to negotiate to their desired +connection interval values. This might be remedied by setting the default +Linux conn_min_interval and conn_max_interval values to the widest +supported range (6 - 3200 / 7.5ms - 4000ms).

This was reported as a +kworker always at 100% of CPU usage, which was narrowed down to be +bnx2x ptp_task. + +By following the ioctl handler, we could narrow down the problem to +an NTP tool (chrony) requesting HW timestamping from bnx2x NIC with +RX filter zeroed; this isn't reproducible for example with ptp4l +(from linuxptp) since this tool requests a supported RX filter. +It seems NIC FW timestamp mechanism cannot work well with +RX_FILTER_NONE - driver's PTP filter init routine skips a register +write to the adapter if there's not a supported filter request. + +This patch addresses the problem of bnx2x ptp thread's everlasting +reschedule by retrying the register read 10 times; between the read +attempts the thread sleeps for an increasing amount of time starting +in 1ms to give FW some time to perform the timestamping. If it still +fails after all retries, we bail out in order to prevent an unbound +resource consumption from bnx2x. + +The patch also adds an ethtool statistic for accounting the skipped +TX timestamp packets and it reduces the priority of timestamping +error messages to prevent log flooding.

Let's fix this by +ignoring any pending edge interrupts for saved_datain. + +This issue affects only idle states where the GPIO module internal +wake-up path is operational. For deeper idle states where the GPIO +module gets powered off, Linux generic wakeirqs must be used for +the padconf wake-up events with pinctrl-single driver.
