Subject: [PATCH net-next,rdma-next v2 0/5][pull request] Prepare for Intel IPU E2000 (GEN3)
This is the first part in introducing RDMA support for idpf.
This shared pull request targets both net-next and rdma-next branches
and is based on tag v6.15-rc1.
v2:
- Free cdev_info and iidc_priv in ice_deinit_rdma() (patch 5)
v1: https://lore.kernel.org/all/20250505212037.2092288-1-anthony.l.nguyen@intel.com/

iidc/ice/irdma: Update IDC to support multiple consumers (2025-05-09 11:35:43 -0700)
----------------------------------------------------------------
Tatyana Nikolova says:
To align with review comments, the patch series introducing RDMA
RoCEv2 support for the Intel Infrastructure Processing Unit (IPU)
E2000 line of products is going to be submitted in three parts:
1. Modify ice to use specific and common IIDC definitions and
pass a core device info to irdma.
2. Add RDMA support to idpf and modify idpf to use specific and
common IIDC definitions and pass a core device info to irdma.
3. Add RDMA RoCEv2 support for the E2000 products, referred to as
GEN3 to irdma.
This first part is a 5 patch series based on the original
"iidc/ice/irdma: Update IDC to support multiple consumers" patch
to allow for multiple CORE PCI drivers, using the auxbus.
Patches:
1) Move header file to new name for clarity and replace ice
specific DSCP define with a kernel equivalent one in irdma
2) Unify naming convention
3) Separate header file into common and driver specific info
4) Replace ice specific DSCP define with a kernel equivalent
one in ice
5) Implement core device info struct and update drivers to use it
