Subject: [PATCH net-next 0/4] net: mana: Add support for the CDX bus
Date: Thu, 24 Sep 2026 17:30:50 +0000	[thread overview]
Message-ID: <20260924173054.589291-1-mawasthi@linux.microsoft.com> (raw)

This series adds CDX bus support to the MANA driver.

The shared GDMA and Ethernet code currently builds together with the PCI
transport. To add another bus without duplicating the driver or adding
configuration checks throughout the shared code, this series separates the
bus-specific operations and builds each transport independently.

Patch 1 introduces gdma_bus_ops and routes bus-specific interrupt, reset,
service, and setup operations through it.

Patch 2 moves the PCI-specific code from gdma_main.c into gdma_pci.c
without changing PCI behavior.

Patch 3 builds the shared code as gdma_core.ko and the PCI transport as
mana.ko. The PCI module keeps its existing name, device table, and
mana.eth/mana.rdma auxiliary-device identities.

Patch 4 adds the CDX transport as mana_cdx.ko for device ID 0x00C2.

  net: mana: Move PCI transport code into gdma_pci.c
  net: mana: Build the PCI transport as a separate module
