2015-05-31net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionalityAmir Vadai1-0/+1
This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4 Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver extends the existing mlx5 driver with Ethernet functionality. This patch contains the driver entry points but does not include transmit and receive (see the previous patch in the series) routines. It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the Ethernet functionality. Currently, Kconfig is programmed to make Ethernet and Infiniband functionality mutally exclusive. Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND being selected.

In the event flow, we currently pass only a port number in the void *data argument. Rather than pass a pointer to the event handlers, we should use an "unsigned long" parameter, and pass the port number value directly.

2014-07-31mlx5: Move pci device handling from mlx5_ib to mlx5_coreJack Morgenstein1-2/+15
In preparation for a new mlx5 device which is VPI (i.e., ports can be either IB or ETH), move the pci device functionality from mlx5_ib to mlx5_core. This involves the following changes: 1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev is now an independent structure maintained by mlx5_core. mlx5_ib_dev now has a pointer to that struct. This requires changing a lot of places where the core_dev struct was accessed via mlx5_ib_dev (now, this needs to be a pointer dereference). 2. All PCI initializations are now done in mlx5_core. Thus, it is now mlx5_core which does pci_register_device (and not mlx5_ib, as was previously). 3. mlx5_ib now registers itself with mlx5_core as an "interface" driver. This is very similar to the mechanism employed for the mlx4 (ConnectX) driver. Once the HCA is initialized (by mlx5_core), it invokes the interface drivers to do their initializations. 4. There is a new event handler which the core registers: mlx5_core_event(). This event handler invokes the event handlers registered by the interfaces.

2014-03-07IB/mlx5: Collect signature error completionSagi Grimberg1-0/+4
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).

2014-02-07IB/mlx5: Fix binary compatibility with libmlx5Eli Cohen1-0/+1
Commit c1be5232d21d ("Fix micro UAR allocator") broke binary compatibility between libmlx5 and mlx5_ib since it defines a different value to the number of micro UARs per page, leading to wrong calculation in libmlx5. This patch defines struct mlx5_ib_alloc_ucontext_req_v2 as an extension to struct mlx5_ib_alloc_ucontext_req. The extended size is determined in mlx5_ib_alloc_ucontext() and in case of old library we use uuarn 0 which works fine -- this is acheived due to create_user_qp() falling back from high to medium then to low class where low class will return 0. For new libraries we use the more sophisticated allocation algorithm.

2013-11-09mlx5: Support communicating arbitrary host page size to firmwareEli Cohen1-0/+1
Connect-IB firmware requires 4K pages to be communicated with the driver. This patch breaks larger pages to 4K units to enable support for architectures utilizing larger page size, such as PowerPC. This patch also fixes several places that referred to PAGE_SHIFT instead of explicit 12 which is the inherent page shift on Connect-IB.

2013-11-09IB/mlx5: Multithreaded create MREli Cohen1-2/+15
Use asynchronous commands to execute up to eight concurrent create MR commands. This is to fill memory caches faster so we keep consuming from there. Also, increase timeout for shrinking caches to five minutes. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-10-10IB/mlx5: Fix eq names to display nicely in /proc/interruptsSagi Grimberg1-1/+1
It's helpful for a driver to put the pci slot name in its interrupt names, so /proc/interrupts will show the pci slot of the device. Signed-off-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>

Checksum calculations consume CPU resources and can be significant to the rate of resource creation/destruction. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2013-08-16net/mlx5_core: Support MANAGE_PAGES and QUERY_PAGES firmware command changesMoshe Lazer1-2/+2
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.

Remove this code, per Dave Miller's request, since it is not being used anywhere in the kernel. Signed-off-by: Eli Cohen <eli@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-08-01mlx5_core: Implement new initialization sequenceEli Cohen1-1/+3
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.

2013-07-08mlx5: Add driver for Mellanox Connect-IB adaptersEli Cohen1-0/+769
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.
