* net/mlx5_core: Remove unused dev cap enum fieldsEli Cohen2014-12-081-8/+0
| | | | | | | These enumerations are not used so remove them. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net/mlx5_core: use set/get macros in device capsEli Cohen2014-10-031-92/+0
| | | | | | | | Transform device capabilities related commands to use set/get macros to manipulate command mailboxes. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net/mlx5_core: Use hardware registers description header fileEli Cohen2014-10-031-0/+44
| | | | | | | | | | | | | Add an auto generated header file that describes hardware registers along with set of macros that set/get values. The macros do static checks to avoid overflow, handle endianess, and overall provide a clean way to code commands. Currently the header file is small and we will add structs as we make use of the macros. A few commands were removed from the commands enum since they are not supported currently and will be added when support is available.

* net/mlx5_core: Update device capabilities handlingEli Cohen2014-10-031-9/+15
| | | | | | | | | | Rearrange struct mlx5_caps so it has a "gen" field to represent the current capabilities configured for the device. Max capabilities can also be queried from the device. Also update capabilities struct to contain more fields as per the latest revision if firmware specification. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: David S.

* mlx5: minor fixes (mainly avoidance of hidden casts)Jack Morgenstein2014-07-301-4/+0
| | | | | | | | | | | | There were many places where parameters which should be u8/u16 were integer type. Additionally, in 2 places, a check for a non-null pointer was added before dereferencing the pointer (this is actually a bug fix).

* IB/mlx5: Add block multicast loopback supportEli Cohen2014-04-101-0/+1
| | | | | | | | | Add support for the block multicast loopback QP creation flag along the proper firmware API for that. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
* IB/mlx5: Collect signature error completionSagi Grimberg2014-03-071-0/+18
| | | | | | | | | | | | | | | | | | | This commit takes care of the generated signature error CQE generated by the HW (if happened). The underlying mlx5 driver will handle signature error completions and will mark the relevant memory region as dirty. Once the consumer gets the completion for the transaction, it must check for signature errors on signature memory region using a new lightweight verb ib_check_mr_status(). In case the user doesn't check for signature error (i.e. doesn't call ib_check_mr_status() with status check IB_MR_CHECK_SIG_STATUS), the memory region cannot be used for another signature operation (REG_SIG_MR work request will fail).

* mlx5: Implement create_mr and destroy_mrSagi Grimberg2014-03-071-0/+25
| | | | | | | | | | | | | | | Support create_mr and destroy_mr verbs. Creating ib_mr may be done for either ib_mr that will register regular page lists like alloc_fast_reg_mr routine, or indirect ib_mrs that can register other (pre-registered) ib_mrs in an indirect manner. In addition user may request signature enable, that will mean that the created ib_mr may be attached with signature attributes (BSF, PSVs). Currently we only allow direct/indirect registration modes.

* mlx5_core: Fix PowerPC supportEli Cohen2014-01-221-1/+2

* IB/mlx5: Add support for resize CQEli Cohen2014-01-221-0/+2

* IB/mlx5: Implement modify CQEli Cohen2014-01-221-0/+15
| | | | | | | | Modify CQ is used by ULPs like IPoIB to change moderation parameters. This patch adds support in mlx5. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
* IB/mlx5: Fix micro UAR allocatorEli Cohen2014-01-141-3/+4
| | | | | | | | | | | | | | The micro UAR (uuar) allocator had a bug which resulted from the fact that in each UAR we only have two micro UARs avaialable, those at index 0 and 1. This patch defines iterators to aid in traversing the list of available micro UARs when allocating a uuar. In addition, change the logic in create_user_qp() so that if high class allocation fails (high class means lower latency), we revert to medium class and not to the low class.

* mlx5: Use enum to indicate adapter page sizeEli Cohen2013-11-081-0/+4
| | | | | | | | | The Connect-IB adapter has an inherent page size which equals 4K. Define an new enum that equals the page shift and use it instead of using the value 12 throughout the code. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
* mlx5: Clear reserved area in set_hca_cap()Eli Cohen2013-11-081-2/+7
| | | | | | | | | | | | Firmware spec requires reserved fields to be cleared when calling set_hca_cap. Current code queries and copy to the set area, possibly resulting in reserved bits not cleared. This patch copies only writable fields to the set area. Fix also typo - msx => max Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

* net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer2013-08-151-12/+10
| | | | | | | | | | | | | | | | | | | | | | | In the previous QUERY_PAGES command version we used one command to get the required amount of boot, init and post init pages. The new version uses the op_mod field to specify whether the query is for the required amount of boot, init or post init pages. In addition the output field size for the required amount of pages increased from 16 to 32 bits. In MANAGE_PAGES command the input_num_entries and output_num_entries fields sizes changed from 16 to 32 bits and the PAS tables offset changed to 0x10. In the pages request event the num_pages field also changed to 32 bits. In the HCA-capabilities-layout the size and location of max_qp_mcg field has been changed to support 24 bits. This patch isn't compatible with firmware versions < 5; however, it turns out that the first GA firmware we will publish will not support previous versions so this should be OK.

* mlx5_core: Implement new initialization sequenceEli Cohen2013-07-311-0/+20
| | | | | | | | | | | | | | | | | Introduce enbale_hca and disable_hca commands to signify when the driver starts or ceases to operate on the device. In addition the driver will use boot and init pages count; boot pages is required to allow firmware to complete boot commands and the other to complete init hca. Command interface revision is bumped to 4 to enforce using supported firmware. This patch breaks compatibility with old versions of firmware (< 4); however, the first GA firmware we will publish will support version 4 so this should not be a problem.

Fix the declaration of this field to be __be16 (which is what is in the firmware spec), renaming the field to log_uar_pg_size to conform to the spec, which fixes the endianness bug reported by sparse.

* mlx5: Add driver for Mellanox Connect-IB adaptersEli Cohen2013-07-081-0/+893
The driver is comprised of two kernel modules: mlx5_ib and mlx5_core. This partitioning resembles what we have for mlx4, except that mlx5_ib is the pci device driver and not mlx5_core. mlx5_core is essentially a library that provides general functionality that is intended to be used by other Mellanox devices that will be introduced in the future. mlx5_ib has a similar role as any hardware device under drivers/infiniband/hw.
