* mlx4_core: Multiple port type supportYevgeny Petrilin2008-10-221-0/+1
| | | | | | | | | | | | Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

* mlx4_core: Get ethernet MTU and default address from firmwareYevgeny Petrilin2008-10-221-1/+3

* mlx4_core: Support multiple pre-reserved QP regionsYevgeny Petrilin2008-10-221-0/+2
| | | | | | | | | | | | | For ethernet support, we need to reserve QPs for the ethernet and fibre channel driver. The QPs are reserved at the end of the QP table. (This way we assure that they are aligned to their size) We need to consider these reserved ranges in bitmap creation, so we extend the mlx4 bitmap utility functions to allow reserved ranges at both the bottom and the top of the range.

* IB/mlx4: Add support for memory management extensions and local DMA L_KeyRoland Dreier2008-07-231-1/+1
| | | | | | | | | | | | | Add support for the following operations to mlx4 when device firmware supports them: - Send with invalidate and local invalidate send queue work requests; - Allocate/free fast register MRs; - Allocate/free fast register MR page lists; - Fast register MR send queue work requests; - Local DMA L_Key.

* mlx4_core: Use MOD_STAT_CFG command to get minimal page sizeVladimir Sokolovsky2008-07-141-0/+6
| | | | | | | | | | | | | | | | | | | | | There was a bug in some versions of the mlx4 driver in mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to be 12. However, new ConnectX firmware can support a minimum page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with old drivers, ib_fmr_alloc() would fail for ULPs using the device minimum when creating FMRs. To preserve firmware compatibility with released mlx4 drivers, the firmware will continue to return 12 as before for log_page_sz in QUERY_DEV_CAP for these drivers. However, to enable new drivers to take advantage of the available smaller page size, the mlx4 driver now first sets the log_pg_sz to the device minimum by setting a log_page_sz value to 0 via the MOD_STAT_CFG command and then reading the real minimum via QUERY_DEV_CAP.

* mlx4_core: Don't read reserved fields in mlx4_QUERY_ADAPTER()Jack Morgenstein2008-02-041-3/+0
| | | | | | | | | | | The firmware QUERY_ADAPTER command does not return vendor_id, device_id, and revision_id; eliminate these fields from the query. Initialize the rev_id field of the mlx4 device via init_node_data (MAD IFC query), as is done in the query_device verb implementation.

* IB/mlx4: Handle FW command interface rev 3Roland Dreier2007-06-181-5/+5
| | | | | | | | | | | Upcoming firmware introduces command interface revision 3, which changes the way port capabilities are queried and set. Update the driver to handle both the new and old command interfaces by adding a new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware interface revision and then using the correct interface based on the setting of the flag.

* IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier2007-05-081-0/+167
Add an InfiniBand driver for Mellanox ConnectX adapters. Because these adapters can also be used as ethernet NICs and Fibre Channel HBAs, the driver is split into two modules: mlx4_core: Handles low-level things like device initialization and processing firmware commands. Also controls resource allocation so that the InfiniBand, ethernet and FC functions can share a device without stepping on each other. mlx4_ib: Handles InfiniBand-specific things; plugs into the InfiniBand midlayer.
