2011-08-11mlx4: Move the Mellanox driverJeff Kirsher1-944/+0
Moves the Mellanox driver into drivers/net/ethernet/mellanox/ and make the necessary Kconfig and Makefile changes. CC: Roland Dreier <roland@kernel.org> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2011-07-18mlx4_core: Add network flow countersOr Gerlitz1-1/+11
ConnectX devices support a set of flow counters that can be attached to a set containing one or more QPs. Each such counter tracks receive and transmit packets and bytes of these QPs. This patch queries the device to check support for counters, handles initialization of the HCA to enable counters, and initializes a bitmap allocator to control counter allocations.

2011-07-18mlx4_core: Read extended capabilities into the flags fieldOr Gerlitz1-13/+11
Query another dword containing up to 32 extended device capabilities and merge it into struct mlx4_caps.flags. Update the code that handles the current extended device capabilities (e.g UDP RSS, WoL, vep steering, etc) to use the extended device cap flags field instead of a field per extended capability.

2011-07-18mlx4_core: Extend capability flags to 64 bitsOr Gerlitz1-4/+5

2011-03-23mlx4_en: Enabling new steeringYevgeny Petrilin1-0/+3
The mlx4_en module now uses the new steering mechanism. The RX packets are now steered through the MCG table instead of Mac table for unicast, and default entry for multicast. The feature is enabled through INIT_HCA Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-01-10mlx4_core: Remove warning message about firmware bugRoland Dreier1-3/+1
The kernel warning message added in commit 58d74bb1d9f7 ("mlx4_core: Workaround firmware bug in query dev cap") about mlx4 reporting the wrong number of "blue flame registers" doesn't really help anyone, since the firmware bug is known and fixed and the bug is pretty much harmless to users. So just get rid of the warning. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2010-12-01mlx4_core: Workaround firmware bug in query dev capEli Cohen1-0/+4
ConnectX firmware is supposed to report the number blue flame registers per page as log2 of the value. However, due to a firmware bug, it reports actual number. This patch works around this by checking if the number of registers calculated fits within a page. If it does not, we use 8 registers per page.

2009-11-12IB/mlx4: Remove limitation on LSO header sizeEli Cohen1-0/+1
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.

2008-10-22mlx4_core: Multiple port type supportYevgeny Petrilin1-0/+4
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: Support multiple pre-reserved QP regionsYevgeny Petrilin1-0/+5
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.

2008-07-14mlx4_core: Use MOD_STAT_CFG command to get minimal page sizeVladimir Sokolovsky1-0/+28
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 Cohen1-0/+4
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 Morgenstein1-6/+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.

2008-01-25mlx4_core: Fix max_eqs masking in QUERY_DEV_CAPJack Morgenstein1-1/+1
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 Morgenstein1-1/+1
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.

2007-06-18IB/mlx4: Handle FW command interface rev 3Roland Dreier1-37/+73
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 Dreier1-1/+1
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 Dreier1-2/+23
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 Dreier1-0/+775
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.
