* IB/mthca: Fill in vendor_err field in completion with errorMichael S. Tsirkin2006-01-061-5/+7
| | | | | | | Fill vendor_err field in completion with error. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/mthca: Fix SRQ cleanup during QP destroyJack Morgenstein2005-12-151-1/+10
| | | | | | | | When cleaning up a CQ for a QP attached to SRQ, need to free an SRQ WQE only if the CQE is a receive completion. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: fix wraparound handling in mthca_cq_clean()Roland Dreier2005-11-101-10/+6
| | | | | | | | Handle case where prod_index has wrapped around and become less than cq->cons_index by checking that their difference as a signed int is positive rather than comparing directly. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB] mthca: report asynchronous CQ eventsMichael S. Tsirkin2005-10-291-1/+30
| | | | | | | Implement reporting asynchronous CQ events in Mellanox HCA driver. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB: move include files to include/rdmaRoland Dreier2005-08-261-1/+1
| | | | | | | | 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 Dreier2005-08-261-12/+20
| | | | | | | Add mthca support for shared receive queues (SRQs), including userspace SRQs. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB/mthca: Simplify handling of completions with errorRoland Dreier2005-08-261-5/+8
| | | | | | | | 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 Dreier2005-08-261-112/+6
| | | | | | | | 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: sparse endianness cleanupSean Hefty2005-08-261-45/+44
| | | | | | | Fix sparse warnings. Use __be* where appropriate. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB: Add copyright noticesRoland Dreier2005-08-261-0/+2
| | | | | | | Make some lawyers happy and add copyright notices for people who forgot to include them when they actually touched the code. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [IB/mthca]: Fix error CQ entry handling on mem-free HCAsRoland Dreier2005-07-271-1/+5
| | | | | | | | Fix handling of error CQ entries on mem-free HCAs: the doorbell count is never valid so we shouldn't look at it. This fixes problems exposed by new HCA firmware. Signed-off-by: Roland Dreier <rolandd@cisco.com>
* [PATCH] IB uverbs: add mthca user CQ supportRoland Dreier2005-07-071-31/+45
| | | | | | | | Add support for userspace completion queues (CQs) to mthca. Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] IB/mthca: Align FW command mailboxes to 4KRoland Dreier2005-06-271-18/+16
| | | | | | | | | | 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 Dreier2005-06-271-1/+1
| | | | | | | | | | | 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: Use dma_alloc_coherent instead of pci_alloc_consistentRoland Dreier2005-06-271-12/+13
| | | | | | | | | | 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.

* [PATCH] IB/mthca: Clean up CQ debugRoland Dreier2005-06-271-21/+18
| | | | | | | | | Clean up CQ debugging code: make dump_cqe print on one line, and only dump error CQ entries for local operation errors. Signed-off-by: Roland Dreier <roland@topspin.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] IB/mthca: encapsulate mem-free check into mthca_is_memfree()Roland Dreier2005-04-161-6/+6
| | | | | | | | | Clean up mem-free mode support by introducing mthca_is_memfree() function, which encapsulates the logic of deciding if a device is mem-free.

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!
