net/mlx5: Remove the flag MLX5_INTERFACE_STATE_SHUTDOWN

2017-08-30T18:20:43+00:00

MLX5_INTERFACE_STATE_SHUTDOWN is not used in the code. Fixes: 5fc7197d3a25 ("net/mlx5: Add pci shutdown callback") Signed-off-by: Huy Nguyen Reviewed-by: Daniel Jurgens Signed-off-by: Saeed Mahameed

net/mlx5: Skip mlx5_unload_one if mlx5_load_one fails

2017-08-30T18:20:43+00:00

There is an issue where the firmware fails during mlx5_load_one, the health_care timer detects the issue and schedules a health_care call. Then the mlx5_load_one detects the issue, cleans up and quits. Then the health_care starts and calls mlx5_unload_one to clean up the resources that no longer exist and causes kernel panic. The root cause is that the bit MLX5_INTERFACE_STATE_DOWN is not set after mlx5_load_one fails. The solution is removing the bit MLX5_INTERFACE_STATE_DOWN and quit mlx5_unload_one if the bit MLX5_INTERFACE_STATE_UP is not set. The bit MLX5_INTERFACE_STATE_DOWN is redundant and we can use MLX5_INTERFACE_STATE_UP instead.

net/mlx5: FPGA, Add SBU infrastructure

2017-06-27T13:36:47+00:00

Add interface to initialize and interact with Innova FPGA SBU connections. A client driver may use these functions to set up a high-speed DMA connection with its SBU hardware logic, and send/receive messages over this connection. A later patch in this patchset will make use of these functions for Innova IPSec offload in mlx5 Ethernet driver. Add commands to retrieve Innova FPGA SBU capabilities, and to read/write Innova FPGA configuration space registers and memory, over internal I2C. At high level, the FPGA configuration space is divided such: 0x00000000 - 0x007fffff is reserved for the SBU 0x00800000 - 0xffffffff is reserved for the Shell 0x400000000 - ... is DDR memory A later patchset will add support for accessing FPGA CrSpace and memory over a high-speed connection. This is the reason for the ACCESS_TYPE enumeration, which currently only supports I2C. Signed-off-by: Ilan Tayari Signed-off-by: Saeed Mahameed

net/mlx5: Add support for multiple RoCE enable

2017-06-27T13:36:47+00:00

Previously, only mlx5_ib enabled RoCE on the port, but FPGA needs it as well. Add support for counting number of enables, so that FPGA and IB can work in parallel and independently. Program the HW to enable RoCE on the first enable call, and program to disable RoCE on the last disable call. Signed-off-by: Ilan Tayari Reviewed-by: Boris Pismenny Signed-off-by: Saeed Mahameed

net/mlx5: Add reserved-gids support

2017-06-27T13:36:47+00:00

Reserved GIDs are entries in the GID table in use by the mlx5_core and its submodules (e.g. FPGA, SRIOV, E-Swtich, netdev). The entries are reserved at the high indexes of the GID table. A mlx5 submodule may reserve a certain amount of GIDs for its own use during the load sequence by calling mlx5_core_reserve_gids, and must also take care to un-reserve these GIDs when it closes. Reservation is only allowed during the load sequence and before any interfaces (e.g. mlx5_ib or mlx5_en) are up. After reservation, a submodule may call mlx5_core_reserved_gid_alloc/ free to allocate entries from the reserved GIDs pool. Reserve a GID table entry for every supported FPGA QP. A later patch in the patchset will remove them from being reported to IB core. Another such patch will make use of these for FPGA QPs in Innova NIC. Added lib/mlx5.h to serve as a library for mlx5 submodlues, and to expose only public mlx5 API, more mlx5 library files will be added in future submissions.

net/mlx5: Cancel delayed recovery work when unloading the driver

2017-06-27T11:49:57+00:00

Draining the health workqueue will ignore future health works including the one that report hardware failure and thus we can't enter error state Instead cancel the recovery flow and make sure only recovery flow won't be scheduled.

net/mlx5: Expose command polling interface

2017-06-15T21:19:43+00:00

Add a new interface for commands execution that allows the caller to wait for the command's completion in a busy-wait loop (polling mode). This is useful if we want to execute a command in a polling mode while the driver is working in events mode for the rest of the commands. This interface will be used in the downstream patches.
