Implement netdev_queue_mgmt_ops for bnxt added in [1]. Two bnxt_rx_ring_info structs are allocated to hold the new/old queue memory. Queue memory is copied from/to the main bp->rx_ring[idx] bnxt_rx_ring_info. Queue memory is pre-allocated in bnxt_queue_mem_alloc() into a clone, and then copied into bp->rx_ring[idx] in bnxt_queue_mem_start(). Similarly, when bp->rx_ring[idx] is stopped its queue memory is copied into a clone, and then freed later in bnxt_queue_mem_free(). I tested this patchset with netdev_rx_queue_restart(), including inducing errors in all places that returns an error code. In all cases, the queue is left in a good working state. Rx queues are created/destroyed using bnxt_hwrm_rx_ring_alloc() and bnxt_hwrm_rx_ring_free(), which issue HWRM_RING_ALLOC and HWRM_RING_FREE commands respectively to the firmware. By the time a HWRM_RING_FREE response is received, there won't be any more completions from that queue. Thanks to Somnath for helping me with this patch. With their permission I've added them as Acked-by. [1]: https://lore.kernel.org/netdev/20240501232549.1327174-2-shailend@google.com/Acked-by:

Johan Jonker says: ==================== cleanup arc emac The Rockchip emac binding for rk3036/rk3066/rk3188 has been converted to YAML with the ethernet-phy node in a mdio node. This requires some driver fixes by someone that can do hardware testing. In order to make a future fix easier make the driver 'Rockchip only' by removing the obsolete part of the arc emac driver. ==================== Signed-off-by: -

In the combined DT of rk3066a/rk3188 the emac node uses as place holder the compatible string "snps,arc-emac". The last real user nSIM_700 of the "snps,arc-emac" compatible string in a driver was removed in 2019. Rockchip emac nodes don't make use of this common fall back string. In order to removed unused driver code replace this string with "rockchip,rk3066-emac". As we are there remove the blank lines and sort. Signed-off-by:

Need only 1 irq by check MPC8313 spec. - Move Reference clock context under clk,sel. - Interrupts is not required property. - Use low case for hex value. - Check reference manual of MPC8313, p1010 and so on, which dts use more than 1 irqs.

Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_devices from struct mt76_dev by converting them into pointers, and allocating them dynamically. Use the leverage alloc_netdev_dummy() to allocate the net_device object at mt76_dma_init(). The free of the device occurs at mt76_dma_cleanup().

The ACPI IDs used in the CS35L56 HDA drivers are all handled by the serial multi-instantiate driver which starts multiple Linux device instances from a single ACPI Device() node. As serial multi-instantiate is not an optional part of the system add it as a dependency in Kconfig so that it is not overlooked. Signed-off-by:

Shannon Nelson says: ==================== ionic: rework fix for doorbell miss A latency test in a scaled out setting (many VMs with many queues) has uncovered an issue with our missed doorbell fix from commit b69585bf ("ionic: missed doorbell workaround") As a refresher, the Elba ASIC has an issue where once in a blue moon it might miss/drop a queue doorbell notification from the driver. This can result in Tx timeouts and potential Rx buffer misses. The basic problem with the original solution is that we're delaying things with a timer for every single queue, periodically using mod_timer() to reset to reset the alarm, and mod_timer() becomes a more and more expensive thing as there are more and more VFs and queues each with their own timer. A ping-pong latency test tends to exacerbate the effect such that every napi is doing a mod_timer() in every cycle. An alternative has been worked out to replace this using periodic workqueue items outside the napi cycle to request a napi_schedule driven by a single delayed-workqueue per device rather than a timer for every queue. Also, now that newer firmware is actually reporting its ASIC type, we can restrict this to the appropriate chip. The testing scenario used 128 VFs in UP state, 16 queues per VF, and latency tests were done using TCP_RR with adaptive interrupt coalescing enabled, running on 1 VF. We would see 99th percentile latencies of up to 900us range, with some max fliers as much as 4ms. With these fixes the 99th percentile latencies are typically well under 50us with the occasional max under 500us. v1: https://lore.kernel.org/netdev/20240610230706.34883-1-shannon.nelson@amd.com/ ==================== Link: https://lore.kernel.org/r/20240619003257.6138-1-shannon.nelson@amd.comSigned-off-by:

If the doorbell workaround isn't required for a certain asic_type then there is no need to run the associated code. Since newer FW versions are finally reporting their asic_type we can use a flag to determine whether or not to do the workaround. Signed-off-by:

We only support (u16)-1 size for rx_copybreak, so we can reduce the field size and move a couple other fields around to save a little space in the ionic_lif struct.

Add a work item for each queue that will be run on the queue's preferred cpu and will schedule another napi. This napi is run in case the device missed a doorbell and didn't process a packet. This is a problem for the Elba asic that happens very rarely. Signed-off-by:

Add the first queued work for checking on the missed doorbell. This is a delayed work item that reschedules itself every cycle starting at probe. Signed-off-by:

Instead of using the system's default workqueue, add a private workqueue for the device to use for its little jobs. This is to better support the new work items we will be adding in the next patches for PF and VF specific jobs, without inundating the system workqueue in a couple of customer cases where our devices get scaled out to 100-200 VFs.

Currently the driver either sets the initial interrupt affinity for its adminq and tx/rx queues on probe or resets it on various down/up/reconfigure flows. If any user and/or user process (i.e. irqbalance) changes IRQ affinity for any of the driver's interrupts that will be reset to driver defaults whenever any down/up/reconfigure operation happens. This is incorrect and is fixed by making 2 changes: 1. Allocate an array of cpumasks that's only allocated on probe and destroyed on remove. 2. Update the cpumask(s) for interrupts that are in use by registering for affinity notifiers. Signed-off-by:
