2023-04-21pds_core: publish events to the clientsShannon Nelson1-0/+2
When the Core device gets an event from the device, or notices the device FW to be up or down, it needs to send those events on to the clients that have an event handler. Add the code to pass along the events to the clients. The entry points pdsc_register_notify() and pdsc_unregister_notify() are EXPORTed for other drivers that want to listen for these events.

2023-04-21pds_core: add the aux client APIShannon Nelson2-0/+8
Add the client API operations for running adminq commands. The core registers the client with the FW, then the client has a context for requesting adminq services. We expect to add additional operations for other clients, including requesting additional private adminqs and IRQs, but don't have the need yet.

2023-04-21pds_core: add auxiliary_bus devicesShannon Nelson2-0/+15
An auxiliary_bus device is created for each vDPA type VF at VF probe and destroyed at VF remove. The aux device name comes from the driver name + VIF type + the unique id assigned at PCI probe. The VFs are always removed on PF remove, so there should be no issues with VFs trying to access missing PF structures. The auxiliary_device names will look like "pds_core.vDPA.nn" where 'nn' is the VF's uid.

2023-04-21pds_core: set up the VIF definitions and defaultsShannon Nelson1-0/+19
The Virtual Interfaces (VIFs) supported by the DSC's configuration (vDPA, Eth, RDMA, etc) are reported in the dev_ident struct and made visible in debugfs. At this point only vDPA is supported in this driver so we only setup devices for that feature.

2023-04-21pds_core: Add adminq processing and commandsShannon Nelson1-1/+10
Add the service routines for submitting and processing the adminq messages and for handling notifyq events. Signed-off-by: Shannon Nelson <shannon.nelson@amd.com> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2023-04-21pds_core: set up device and adminqShannon Nelson1-0/+638
Set up the basic adminq and notifyq queue structures. These are used mostly by the client drivers for feature configuration. These are essentially the same adminq and notifyq as in the ionic driver. Part of this includes querying for device identity and FW information, so we can make that available to devlink dev info. $ devlink dev info pci/0000:b5:00.0 pci/0000:b5:00.0: driver pds_core serial_number FLM18420073 versions: fixed: asic.id 0x0 asic.rev 0x0 running: fw 1.51.0-73 stored: fw.goldfw 1.15.9-C-22 fw.mainfwa 1.60.0-73 fw.mainfwb 1.60.0-57 Signed-off-by: Shannon Nelson <shannon.nelson@amd.com> Acked-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: David S.

2023-04-21pds_core: add devcmd device interfacesShannon Nelson2-0/+193
The devcmd interface is the basic connection to the device through the PCI BAR for low level identification and command services. This does the early device initialization and finds the identity data, and adds devcmd routines to be used by later driver bits.

2023-04-21pds_core: initial framework for pds_core PF driverShannon Nelson2-0/+585
This is the initial PCI driver framework for the new pds_core device driver and its family of devices. This does the very basics of registering for the new PF PCI device 1dd8:100c, setting up debugfs entries, and registering with devlink.
