| | | | | | | | | | | | | | | | Make sure that the P_Key index passed into mthca_modify_qp() is within the device's P_Key table. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* | [PATCH] fix missing includesTim Schmielau2005-10-30
|/ | | | | | | | | | | | | | | | | | | | | I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

* [IB] mthca: correct modify QP attribute masks for UCRoland Dreier2005-10-25
| | | | | | | | The UC transport does not support RDMA reads or atomic operations, so we shouldn't require or even allow the consumer to set attributes relating to these operations for UC QPs. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: Better limit checking and reportingJack Morgenstein2005-10-17
| | | | | | | | | Check the sizes of CQs, QPs and SRQs when creating objects, and fail instead of creating too-big queues. Also return real limits instead of just plausible-sounding values from mthca_query_device(). Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Fix device removal memory leakMichael S. Tsirkin2005-09-20

* [PATCH] IB/mthca: fix posting of first work requestRoland Dreier2005-09-19
| | | | | | | | | | | Fix posting first WQE for mem-free HCAs: we need to link to previous WQE even in that case. While we're at it, simplify code for Tavor-mode HCAs. We don't really need the conditional test there either; we can similarly always link to the previous WQE. Based on Michael S. Tsirkin's analogous fix for userspace libmthca.

* [PATCH] IB/mthca: assign ACK timeout field correctlyRoland Dreier2005-09-19
| | | | | | | | | The hardware reads the ACK timeout field from the most significant 5 bits of struct mthca_qp_path's ackto field, not the least significant bits. This fix has the driver put the timeout in the right place. Without this, we get a timeout that is 2^8 times too small. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB: Initialize qp->waitMichael S. Tsirkin2005-09-07

* [PATCH] IB: really reset QPsRoland Dreier2005-09-07
| | | | | | | When we modify a QP to the RESET state, completely clean up the QP so that it is really and truly reset. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB: move include files to include/rdmaRoland Dreier2005-08-26
| | | | | | | | Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Add SRQ implementationRoland Dreier2005-08-26
| | | | | | | Add mthca support for shared receive queues (SRQs), including userspace SRQs. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Move WQE structures into their own headerRoland Dreier2005-08-26
| | | | | | | | Move the definitions of the WQE structures from mthca_qp.c into mthca_wqe.h, so that we'll be able to share them when we add the SRQ code in mthca_srq.c. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Simplify handling of completions with errorRoland Dreier2005-08-26
| | | | | | | | Mem-free HCAs never generate error CQEs that complete multiple WQEs, so just skip the call to mthca_free_err_wqe() for them rather than having logic to handle the mem-free case in mthca_free_err_wqe(). Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Factor out common queue alloc codeRoland Dreier2005-08-26
| | | | | | | | Clean up the allocation of memory for queues by factoring out the common code into mthca_buf_alloc() and mthca_buf_free(). Now CQs and QPs share the same queue allocation code, which we'll also use for SRQs. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Use correct port width capability valueRoland Dreier2005-08-26
| | | | | | | | | When we call the INIT_IB firmware command to bring up a port, use the actual port width capability returned by the QUERY_DEV_LIM command instead of always trying to enable both 1X and 4X. This fixes breakage seen when the firmware is build to allow 4X only. Signed-off-by: Roland Dreier <rolandd@cisco.com>

* [PATCH] IB/mthca: Align FW command mailboxes to 4KRoland Dreier2005-06-27
| | | | | | | | | | Future versions of Mellanox HCA firmware will require command mailboxes to be aligned to 4K. Support this by using a pci_pool to allocate all mailboxes. This has the added benefit of shrinking the source and text of mthca.

* [PATCH] IB/mthca: Move mthca_is_memfree checksRoland Dreier2005-06-27
| | | | | | | | | | | Make mthca_table_put() and mthca_table_put_range() NOPs if the device is not mem-free, so that we don't have to have "if (mthca_is_memfree())" tests in the callers of these functions. This makes our code more readable and maintainable, and saves a couple dozen bytes of text in ib_mthca.ko as well.

* [PATCH] IB/mthca: Set RDMA/atomic capabilities correctlyRoland Dreier2005-06-27
| | | | | | | | | | | | | mthca apparently had the meanings of the max_rd_atomic and max_dest_rd_atomic QP attributes backwards. max_rd_atomic limits the maximum number of outstanding RDMA/atomic requests as an initiator (on a send queue), and max_dest_rd_atomic specifies the resources allocated to handle RMDA/atomic requests from the remote end of the connection. We were programming our QP context with these values swapped.

* [PATCH] IB/mthca: Use dma_alloc_coherent instead of pci_alloc_consistentRoland Dreier2005-06-27
| | | | | | | | | | Switch all allocations of coherent memory from pci_alloc_consistent() to dma_alloc_coherent(), so that we can pass GFP_KERNEL. This should help when the system is low on memory.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
