2005-06-27[PATCH] IB/mthca: Set RDMA/atomic capabilities correctlyRoland Dreier
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.

2005-06-27[PATCH] IB/mthca: Use dma_alloc_coherent instead of pci_alloc_consistentRoland Dreier
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.

2005-04-16[PATCH] IB/mthca: add support for new MT25204 HCARoland Dreier
Decouple table of HCA features from exact HCA device type. Add a current FW version field so we can warn when someone is using old FW. Add support for new MT25204 HCA. Remove the warning about mem-free support, since it should be pretty solid at this point.

2005-04-16[PATCH] IB/mthca: add fast memory region implementationMichael S. Tsirkin
Implement fast memory regions (FMRs), where the driver writes directly into the HCA's translation tables rather than requiring a firmware command. For Tavor, MTTs for FMR are separate from regular MTTs, and are reserved at driver initialization. This is done to limit the amount of virtual memory needed to map the MTTs. For Arbel, there's no such limitation, and all MTTs and MPTs may be used for FMR or for regular MR. Signed-off-by: Michael S.

2005-04-16[PATCH] IB/mthca: fix MTT allocation in mem-free modeRoland Dreier
Fix bug in MTT allocation in mem-free mode. I misunderstood the MTT size value returned by the firmware -- it is really the size of a single MTT entry, since mem-free mode does not segment the MTT as the original firmware did. This meant that our MTT addresses ended up being off by a factor of 8. This meant that our MTT allocations might overlap, and so we could overwrite and corrupt earlier memory regions when writing new MTT entries. We fix this by always using our 64-byte MTT segment size. This allows some simplification of the code as well, since there's no reason to put the MTT segment size in a variable -- we can always use our enum value directly.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
