2009-11-12mlx4_core: Fix parsing of reserved EQ capYevgeny Petrilin
Value returned by firmware is the actual value, not a log. Signed-off-by: Liran Liss <liranl@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2009-11-12IB/mlx4: Remove limitation on LSO header sizeEli Cohen
Current code has a limitation: an LSO header is not allowed to cross a 64 byte boundary. This patch removes this limitation by setting the WQE RR for large headers thus allowing LSO headers of any size. The extra buffer reserved for MLX4_IB_QP_LSO QPs has been doubled, from 64 to 128 bytes, assuming this is reasonable upper limit for header length. Also, this patch will cause IB_DEVICE_UD_TSO to be set only for HCA FW versions that set MLX4_DEV_CAP_FLAG_BLH; e.g. FW version 2.6.000 and higher.

ConnectX can work more efficiently if the CPU cache line size is passed to it with the INIT_HCA firmware command. Signed-off-by: Eli Cohen <eli@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2008-10-22mlx4_core: Multiple port type supportYevgeny Petrilin
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.

2008-10-22mlx4_core: Get ethernet MTU and default address from firmwareYevgeny Petrilin
Get maximum ethernet MTU and default MAC address from the firmware QUERY_DEV_CAP command. Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-10-22mlx4_core: Support multiple pre-reserved QP regionsYevgeny Petrilin
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.

2008-07-25mlx4: Update/add Mellanox Technologies copyright lines to mlx4 driver filesJack Morgenstein
Update existing Mellanox copyright lines to 2008, and add such lines to files where they are missing. Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-07-23IB/mlx4: Add support for memory management extensions and local DMA L_KeyRoland Dreier
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. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-07-22mlx4_core: Add module parameter to enable QoS supportJack Morgenstein
Add a module parameter "enable_qos" to mlx4_core. If this param is set, enable support for QoS in the INIT_HCA command. By default, the parameter is set to 0 (disabled). Signed-off-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-07-14mlx4_core: Use MOD_STAT_CFG command to get minimal page sizeVladimir Sokolovsky
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.

2008-04-16IB/mlx4: Add IPoIB checksum offload supportEli Cohen
ConnectX devices support checksum generation and verification of TCP and UDP packets for UD IPoIB messages. This patch checks if the HCA supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it does. It implements support for handling the IB_SEND_IP_CSUM send flag and setting the csum_ok field in receive work completions.

2008-02-04mlx4_core: Don't read reserved fields in mlx4_QUERY_ADAPTER()Jack Morgenstein
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.

2008-01-25mlx4_core: Fix max_eqs masking in QUERY_DEV_CAPJack Morgenstein
log_max_eqs is a 4-bit field, not a 3-bit field in the response to the QUERY_DEV_CAP FW command, so we should mask with 0xf instead of 0x7 when reading it. Found by Yossi Leybovitch of Mellanox.

2007-10-21mlx4_core: Increase command timeout for INIT_HCA to 10 secondsJack Morgenstein
The current INIT_HCA firmware command timeout is sufficient for the default number of resources (QPs, CQs, etc) being allocated, but if the HCA profile is modified to increase the amount of resources, then a spurious timeout is detected and HCA initialization fails. Increase the timeout for the INIT_HCA command to 10 seconds, which also brings it into line with all the other command timeouts.

2007-10-09mlx4_core: Change capability decoding: SRC->XRCRoland Dreier
The SRC ("scalable RC") transport has been renamed to XRC ("extended RC"), to avoid having an abbreviation that is so easily confused with an abbreviation for "source." Update the HCA capability decoding output to use the new name. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-06-18IB/mlx4: Handle FW command interface rev 3Roland Dreier
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. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-06-18IB/mlx4: Handle new FW requirement for send request prefetchingRoland Dreier
New ConnectX firmware introduces FW command interface revision 2, which requires that for each QP, a chunk of send queue entries (the "headroom") is kept marked as invalid, so that the HCA doesn't get confused if it prefetches entries that haven't been posted yet. Add code to the driver to do this, and also update the user ABI so that userspace can request that the prefetcher be turned off for userspace QPs (we just leave the prefetcher on for all kernel QPs). Unfortunately, marking send queue entries this way is confuses older firmware, so we change the driver to allow only FW command interface revisions 2. This means that users will have to update their firmware to work with the new driver, but the firmware is changing quickly and the old firmware has lots of other bugs anyway, so this shouldn't be too big a deal. Based on a patch from Jack Morgenstein <jackm@dev.mellanox.co.il>. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-06-07mlx4_core: Check firmware command interface revisionRoland Dreier
HCA firmware with incompatible changes to the FW commmand interface is coming soon. Add a check of the interface revision during initialization and bail out if the firmware advertises a revision that the driver doesn't know about. This will avoid strange failures later if the driver goes on using the wrong interface revision. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2007-05-08IB/mlx4: Add a driver Mellanox ConnectX InfiniBand adaptersRoland Dreier
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.
