Set the max_msg_sz port property correctly in mthca's port_query function. Also zero out the attr struct so that we don't leave any other members uninitialized. Signed-off-by:

Add support for mmap() method to mthca, so that userspace can get access to doorbell registers. This allows userspace to get direct access to the HCA for data path operations. Each userspace context gets its own copy of the doorbell registers and is only allowed to use resources that the kernel has given it access to. In other words, this is safe. Signed-off-by:

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. Signed-off-by:

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:

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!
