net: ionic: Provide doorbell and CMB region information

2025-09-11T06:18:36Z

The RDMA device needs information of controller memory bar and doorbell capability to share with user context. Discover CMB regions and express doorbell capabilities on device init.

net: ionic: Create an auxiliary device for rdma driver

2025-09-11T06:18:35Z

To support RDMA capable ethernet device, create an auxiliary device in the ionic Ethernet driver. The RDMA device is modeled as an auxiliary device to the Ethernet device.

ionic: cancel delayed work earlier in remove

2025-06-13T09:31:06Z

Cancel any entries on the delayed work queue before starting to tear down the lif to be sure there is no race with any other events. Signed-off-by: Shannon Nelson Reviewed-by: Simon Horman Reviewed-by: Joe Damato Signed-off-by: David S. Miller

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12Z

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree over and remove the historical wrapper inlines. Conversion was done with coccinelle plus manual fixups where necessary. Signed-off-by: Thomas Gleixner Signed-off-by: Ingo Molnar

drivers: net: ionic: add missed debugfs cleanup to ionic_probe() error path

2024-11-07T19:40:50Z

The ionic_setup_one() creates a debugfs entry for ionic upon successful execution. However, the ionic_probe() does not release the dentry before returning, resulting in a memory leak. To fix this bug, we add the ionic_debugfs_del_dev() to release the resources in a timely manner before returning.

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: advertise 52-bit addressing limitation for MSI-X

2024-06-05T22:53:22Z

Current ionic devices only support 52 internal physical address lines. This is sufficient for x86_64 systems which have similar limitations but does not apply to all other architectures, notably IBM POWER (ppc64). To ensure that MSI/MSI-X vectors are not set outside the physical address limits of the NIC, set the no_64bit_msi value of the pci_dev structure during device probe.

ionic: check before releasing pci regions

2024-02-27T12:03:32Z

AER recovery handler can trigger a PCI Reset after tearing down the device setup in the error detection handler. The PCI Reset handler will also attempt to tear down the device setup, and this second tear down needs to know that it doesn't need to call pci_release_regions() a second time. We can clear num_bars on tear down and use that to decide later if we need to clear the resources. This prevents a harmless but disturbing warning message resource: Trying to free nonexistent resource <0xXXXXXXXXXX-0xXXXXXXXXXX> Fixes: c3a910e1c47a ("ionic: fill out pci error handlers") Reviewed-by: Brett Creeley Signed-off-by: Shannon Nelson Signed-off-by: Paolo Abeni
