Here's a short summary of what my plans for 2.6.22 are. For reference, everything is in my git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git
Please let me know if you have any thoughts on these plans, or if there is something that you feel is missing from this list.
* mlx4 driver for new Mellanox ConnectX HCAs. This is the connectx branch in git. I will merge this soon, after a few more cleanups and one final posting for review. There are actually two parts here:
- "IB/uverbs: Export ib_umem_get()/ib_umem_release() to modules" This touches the core and all drivers, but I think it is a better design and actually helps other drivers too in addition to being a prerequisite for the mlx4 driver. I haven't heard anyone speak out against it so I plan to go ahead and merge it.
- "IB/mlx4: Add driver for Mellanox ConnectX HCAs" I'll fold all the mlx4_core and mlx4_ib code into this patch and merge it.
- "mlx4_eth: Add 10 gigabit ethernet driver for Mellanox ConnectX" This will NOT be merged for 2.6.22 at least. For one thing it is pretty much just a stub that doesn't do anything useful. When there is working 10 gig support, I'll post this to lkml and netdev for review, but this is 2.6.23 stuff at the soonest.
* IPoIB NAPI work. This is the ipoib branch in git. Again, there are really two parts here:
- "IB: Return "maybe missed event" hint from ib_req_notify_cq()" This extends the API in a way that lets us implement NAPI, but may be useful for other things too. It touches all the drivers, and I still need to finish updating cxgb3 to work correctly. I haven't heard anything negative about this, so I'll fix it up, post it one more time for review, and plan on merging it.
- "IPoIB: Convert to NAPI" This is the actual conversion of IPoIB to use NAPI, based on the previous extension to ib_req_notify_cq(). There seems to be a need to merge this, based on people's experiences with congestion collapse under high load. So I'm planning on merging this too.
* I also have the following bunch of more minor patches queued, and I will ask Linus to pull them soon. The majority of them are ipath fixes (and I hope Qlogic will send fixes for the two other bugs that I know of, namely corrupting the list of pending mmaps if an object is destroyed before userspace mmaps it, and doing spin_lock_irq() from interrupt context). There are a few other cleanups and minor fixes scattered around. Here's the shortlog of the for-2.6.22 branch:
Arthur Jones (2): IB/ipath: Call free_irq() on chip specific initialization failure IB/ipath: Force PIOAvail update entry point

Hal Rosenstock (3): IB/umad: Fix declaration of dev_map[] IB/mad: Change SMI to use enums rather than magic return codes IB/umad: Clarify documentation of transaction ID
Joachim Fenkes (2): IB/ehca: Implement modify_port IB: Set class_dev->dev in core for nice device symlink
Mark Debbage (1): IB/ipath: Allow receive ports mapped into userspace to be shared
Michael Albaugh (1): IB/ipath: Fix driver crash (in interrupt or during unload) after chip reset
Ralph Campbell (8): IB/ipath: Don't initialize port memory for subports IB/ipath: Fix SRQ limit event causing dropped CQ entry IB/ipath: NMI cpu lockup if local loopback used IB/ipath: Support larger IB_QP_MAX_DEST_RD_ATOMIC and IB_QP_MAX_QP_RD_ATOMIC IB/ipath: Fix QP error completion queue entries IB/ipath: Fix PSN update for RC retries IB/ipath: Fix port sharing on powerpc IB/ipath: Fix RDMA reads of length zero and error handling
Robert Walsh (4): IB/ipath: Check reserved memory keys IB/ipath: Remove duplicate stuff from ipath_verbs.h IB/ipath: Check that a UD work request's address handle is valid IB/ipath: Fix WC format drift between user and kernel space
Roland Dreier (6): IB: Remove reference to obsolete CONFIG_IPATH_CORE IPoIB: Remove pointless opcode field from debugging output IB/mthca: Update HCA firmware revisions IB/mthca: Fix mthca_write_mtt() on HCAs with hidden memory IB/mthca: Simplify CQ cleaning in mthca_free_qp() IPoIB/cm: spin_lock_irqsave() -> spin_lock_irq() replacements
Sean Hefty (5): RDMA/ucma: Simplify ucma_get_event() IB/ucm: Simplify ib_ucm_event() IB/sa: Set src_path_bits correctly in ib_init_ah_from_path() IB/ipoib: Use ib_init_ah_from_path to initialize ah_attr IB/umad: Implement GRH handling for sent/received MADs - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
