2006-03-20IB/mthca: Implement query_ah methodJack Morgenstein
Implement query_ah (except for AVs which are in HCA memory). This is needed to implement RMPP duplicate session detection on sending side (extraction of DGID/DLID and GRH flag from address handle). Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-03-20IB/mthca: Support for query QP and SRQEli Cohen
Implement the query_qp and query_srq methods in mthca. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-03-20IB/mthca: Add modify_device method to set node descriptionRoland Dreier
Add a modify_device method to mthca, which implements setting the node description. This makes the writable "node_desc" sysfs attribute work for Mellanox HCAs. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-03-20IB/mthca: Whitespace cleanupsRoland Dreier

2006-03-20IB/mthca: Add device-specific support for resizing CQsRoland Dreier
Add low-level driver support for resizing CQs (both kernel and userspace) to mthca. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-01-30IB/mthca: Semaphore to mutex conversionsRoland Dreier
Convert semaphores to mutexes in mthca. Leave firmware command interface poll_sem and event_sem as semaphores. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-01-12IB/mthca: Fix memory leaks in error handlingJack Morgenstein
Fix memory leaks in mthca_create_qp() and mthca_create_srq() error handling. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-01-10IB: Add node_guid to struct ib_deviceSean Hefty
Add a node_guid field to struct ib_device. It is the responsibility of the low-level driver to initialize this field before registering a device with the midlayer. Convert everyone to looking at this field instead of calling ib_query_device() when all they want is the node GUID, and remove the node_guid field from struct ib_device_attr.

2006-01-09IB/mthca: Factor common MAD initialization codeRoland Dreier
Factor out common code for initializing MAD packets, which is shared by many query routines in mthca_provider.c, into init_query_mad(). add/remove: 1/0 grow/shrink: 0/4 up/down: 16/-44 (-28) function old new delta init_query_mad - 16 +16 mthca_query_port 521 518 -3 mthca_query_pkey 301 294 -7 mthca_query_device 648 641 -7 mthca_query_gid 453 426 -27 Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-01-09IB/mthca: fix page shift calculation in mthca_reg_phys_mr()Michael S. Tsirkin
For all pages except possibly the last one, the byte beyond the buffer end must be page aligned. Therefore, when computing the page shift to use, OR the end addresses of the buffers as well as the start addresses into the mask we check. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-10[IB] uverbs: have kernel return QP capabilitiesJack Morgenstein
Move the computation of QP capabilities (max scatter/gather entries, max inline data, etc) into the kernel, and have the uverbs module return the values as part of the create QP response. This keeps precise knowledge of device limits in the low-level kernel driver. This requires an ABI bump, so while we're making changes, get rid of the max_sge parameter for the modify SRQ command -- it's not used and shouldn't be there.

2005-11-04[IB] mthca: report page size capabilityJack Morgenstein
Report the device's real page size capability in mthca_query_device(). Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-11-02[IB] mthca: fix format of FW versionRoland Dreier
Mellanox has decided that the components of the firmware version are really meant to be displayed in decimal, e.g. 0x000400070190 is version 4.7.400. Change the format we use from "%x.%x.%x" to "%d.%d.%d" to match this convention. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-27[IB] mthca: first pass at catastrophic error reportingRoland Dreier
Add some initial support for detecting and reporting catastrophic errors reported by Mellanox HCAs. We start a periodic timer which polls the catastrophic error reporting buffer in device memory. If an error is detected, we dump the contents of the buffer for port-mortem debugging, and report a fatal asynchronous error to higher levels. In the future we can try to recover from these errors by resetting the device, but this will require some work in higher-level code as well. Let's get this in now, so that we at least get catastrophic errors reported in logs. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IB] uverbs: Add a mask of device methods allowed for userspaceRoland Dreier
Give each device a uverbs_cmd_mask, so that a low-level driver can control which methods may be called on behalf of userspace. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IB] mthca: Better limit checking and reportingJack Morgenstein
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>
2005-10-17[IB] mthca: SRQ limit reached eventsRoland Dreier
Our hardware supports generating an event when the number of receives posted to a shared receive queue (SRQ) falls below a user-specified limit. Implement mthca_modify_srq() to arm the limit, and add code to handle dispatching SRQ events when they occur. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IB] mthca: Fill in more fields in query_port methodJack Morgenstein
Add code to fill in the bad_pkey_cntr, max_mtu, active_mtu and subnet_timeout fields in mthca_query_port(). Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-10-17[IB] uverbs: Add device-specific ABI version attributeRoland Dreier

2005-09-27[IB] mthca: fix hw_ver value returned from mthca_query_deviceJack Morgenstein
The IB spec defines the field to be 32 bits, not 16 bits. Signed-off-by: Jack Morgenstein <jackm@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IB: move include files to include/rdmaRoland Dreier
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>
2005-08-26[PATCH] IB/mthca: Add SRQ implementationRoland Dreier
Add mthca support for shared receive queues (SRQs), including userspace SRQs. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IB/mthca: Report correct max_msg_szRoland Dreier
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: Roland Dreier <rolandd@cisco.com>

2005-07-07[PATCH] IB uverbs: add mthca mmap supportRoland Dreier
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.

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.

2005-04-16Linux-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!
