module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

RDMA/mana_ib: use the correct page size for mapping user-mode doorbell page

2024-09-02T07:32:08Z

When mapping doorbell page from user-mode, the driver should use the system page size as this memory is allocated via mmap() from user-mode.

RDMA/mana_ib: use the correct page table index based on hardware page size

2024-09-02T07:32:08Z

MANA hardware uses 4k page size. When calculating the page table index, it should use the hardware page size, not the system page size.

RDMA/mana_ib: Set correct device into ib

2024-07-14T07:49:53Z

Add mana_get_primary_netdev_rcu helper to get a primary netdevice for a given port. When mana is used with netvsc, the VF netdev is controlled by an upper netvsc device. In a baremetal case, the VF netdev is the primary device. Use the mana_get_primary_netdev_rcu() helper in the mana_ib to get the correct device for querying network states.

RDMA: Pass entire uverbs attr bundle to create cq function

2024-06-27T19:28:21Z

Changes the create_cq verb signature by sending the entire uverbs attr bundle as a parameter. This allows drivers to send driver specific attrs through ioctl for the create_cq verb and access them in their driver specific code. Also adds a new enum value for driver specific ioctl attributes for methods already supporting UHW.

net: mana: Allow variable size indirection table

2024-06-12T18:08:42Z

Allow variable size indirection table allocation in MANA instead of using a constant value MANA_INDIRECT_TABLE_SIZE. The size is now derived from the MANA_QUERY_VPORT_CONFIG and the indirection table is allocated dynamically.
