net: ionic: Export the APIs from net driver to support device commands

2025-09-11T06:18:35Z

RDMA driver needs to establish admin queues to support admin operations. Export the APIs to send device commands for the RDMA driver.

ionic: add asic codes to firmware interface file

2024-12-12T11:06:32Z

Now that the firmware has learned how to properly report the asic type id, add the values to our interface file. The sharp-eyed reviewers will catch that the CAPRI value changed here from 0 to 1. This comes with the FW actually defining it correctly. This is safe for us to change as nothing actually uses that value yet.

ionic: Only run the doorbell workaround for certain asic_type

2024-06-20T01:31:49Z

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.

ionic: add work item for missed-doorbell check

2024-06-20T01:31:48Z

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: Shannon Nelson Link: https://lore.kernel.org/r/20240619003257.6138-5-shannon.nelson@amd.com Signed-off-by: Jakub Kicinski

ionic: add private workqueue per-device

2024-06-20T01:31:48Z

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.

ionic: Keep interrupt affinity up to date

2024-06-20T01:31:33Z

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.

ionic: remove the cq_info to save more memory

2024-03-08T11:54:34Z

With a little simple math we don't need another struct array to find the completion structs, so we can remove the ionic_cq_info altogether. This doesn't really save anything in the ionic_cq since it gets padded out to the cacheline, but it does remove the parallel array allocation of 8 * num_descriptors, or about 8 Kbytes per queue in a default configuration.

ionic: Use cached VF attributes

2023-12-06T04:49:50Z

Each time a VF attribute is set via iproute a call to get the VF configuration is also made. This is currently problematic because for each VF configuration call there are multiple commands sent to the device. Unfortunately, this doesn't scale well. Fix this by reporting the cached VF attributes. The original change to query the device for getting the VF attributes f16f5be31009 ("ionic: Query FW when getting VF info via ndo_get_vf_config") was made to remain consistent with device set VF attributes. However, after further investigation there is no need to query the device.
