* net: ipa: repurpose CLOCK_HELD flagAlex Elder2020-09-182-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous patch causes a system resume to be triggered when a packet is available for receipt on a suspended RX endpoint. The CLOCK_HELD flag was previously used to indicate that an extra clock reference was held, preventing suspend. But we no longer need such a flag: - We take an initial reference in ipa_config(). - That reference is held until ipa_suspend() releases it. - A subsequent system resume leads to a reference getting re-acquired in ipa_resume(). - This can repeat until ultimately the module is removed, where ipa_remove() releases the reference. We no longer need a special flag to determine whether this extra reference is held--it is, provided probe has completed successfully and the driver is not suspended (or removed). On the other hand, once suspended, it's possible for more than one endpoint to trip the IPA SUSPEND interrupt, and we only want to trigger the system resume once. So repurpose the Boolean CLOCK_HELD flag to record whether the IPA SUSPEND handler should initiate a system resume. The flag will be be cleared each time ipa_suspend() is called, *before* any endpoints are suspended. And it will be set inside the IPA SUSPEND interrupt handler exactly once per suspend. Rename the flag IPA_FLAG_RESUMED to reflect its new purpose. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: ipa: use device_init_wakeup()Alex Elder2020-09-182-26/+18
| | | | | | | | | | | | | | | | | | | | | | | The call to wakeup_source_register() in ipa_probe() does not do what it was intended to do. Call device_init_wakeup() in ipa_setup() instead, to set the IPA device as wakeup-capable and to initially enable wakeup capability. When we receive a SUSPEND interrupt, call pm_wakeup_dev_event() with a zero processing time, to simply call for a resume without any other processing. The ipa_resume() call will take care of waking things up again, and will handle receiving the packet. Note that this gets rid of a clock reference counting bug that occurred when handling an IPA SUSPEND interrupt. Specifically, ipa_suspend_handler() took an IPA clock reference *in addition* to the one taken by ipa_resume(). There is no need to back-port this fix however, because it only affects code that was not previously working (this patch is part of fixing that).

* net: ipa: manage endpoints separate from clockAlex Elder2020-09-182-10/+12
| | | | | | | | | | | | | | | | Currently, when (before) the last IPA clock reference is dropped, all endpoints are suspended. And whenever the first IPA clock reference is taken, all endpoints are resumed (or started). In most cases there's no need to start endpoints when the clock starts. So move the calls to ipa_endpoint_suspend() and ipa_endpoint_resume() out of ipa_clock_put() and ipa_clock_get(), respectiely. Instead, only suspend endpoints when handling a system suspend, and only resume endpoints when handling a system resume.

* dpaa2-eth: support PTP Sync packet one-step timestampingYangbo Lu2020-09-183-16/+209
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add PTP sync packet one-step timestamping support. Before egress, one-step timestamping enablement needs, - Enabling timestamp and FAS (Frame Annotation Status) in dpni buffer layout. - Write timestamp to frame annotation and set PTP bit in FAS to mark as one-step timestamping event. - Enabling one-step timestamping by dpni_set_single_step_cfg() API, with offset provided to insert correction time on frame. The offset must respect all MAC headers, VLAN tags and other protocol headers accordingly. The correction field update can consider delays up to one second. So PTP frame needs to be filtered and parsed, and written timestamp into Sync frame originTimestamp field. The operation of API dpni_set_single_step_cfg() has to be done when no one-step timestamping frames are in flight. So we have to make sure the last one-step timestamping frame has already been transmitted on hardware before starting to send the current one. The resolution is, - Utilize skb->cb[0] to mark timestamping request per packet. If it is one-step timestamping PTP sync packet, queue to skb queue. If not, transmit immediately. - Schedule a work to transmit skbs in skb queue. - mutex lock is used to ensure the last one-step timestamping packet has already been transmitted on hardware through TX confirmation queue before transmitting current packet.

| | | | | | | | | | | | | | | | | This patch is a preparation for next hardware one-step timestamping support. For DPAA2, the one step timestamping configuration on hardware registers has to be done when there is no one-step timestamping packet in flight. So we will have to use workqueue and skb queue for such packets transmitting, to make sure waiting the last packet has already been sent on hardware, and starting to transmit the current one. So the tx timestamping flag in private data may not reflect the actual request for the one-step timestamping packets of skb queue. This also affects skb headroom allocation. Let's use skb->cb[0] to mark the timestamping request for each skb. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* ionic: add devlink firmware updateShannon Nelson2020-09-185-9/+239
| | | | | | | | | | | | | | | | | Add support for firmware update through the devlink interface. This update copies the firmware object into the device, asks the current firmware to install it, then asks the firmware to select the new firmware for the next boot-up. The install and select steps are launched as asynchronous requests, which are then followed up with status request commands. These status request commands will be answered with an EAGAIN return value and will try again until the request has completed or reached the timeout specified.

* mlxsw: spectrum_qdisc: Disable port buffer autoresize with qdiscsPetr Machata2020-09-171-1/+33
| | | | | | | | | | | | | | | There are two interfaces to configure ETS: qdiscs and DCB. Historically, DCB ETS configuration was projected to ingress as well, and configured port buffers. Qdisc was not. Keep qdiscs behaving this way, and if an offloaded qdisc is configured on a port, move this port's headroom to a manual mode, thus allowing configuration of port buffers through dcbnl_setbuffer.
