net/mlx5e: Add HW cacheline start padding

2015-06-11T22:55:25+00:00

Enable HW cacheline start padding and align RX WQE size to cacheline
while considering HW start padding. Also, fix dma_unmap call to use
the correct SKB data buffer size.

net/mlx5_core: Add new query HCA vport commands

2015-06-04T23:41:01+00:00

Added the implementation for the following commands:

1. QUERY_HCA_VPORT_GID
2. QUERY_HCA_VPORT_PKEY
3. QUERY_HCA_VPORT_CONTEXT

They will be needed when we move to work with ISSI > 0 in the IB driver too.

net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionality

2015-05-31T01:24:51+00:00

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.

net/mlx5_core: New device capabilities handling

2015-05-31T01:23:22+00:00

- Query all supported types of dev caps on driver load.
- Store the Cap data outbox per cap type into driver private data.
- Introduce new Macros to access/dump stored caps (using the auto
  generated data types).
- Obsolete SW representation of dev caps (no need for SW copy for each
  cap).
- Modify IB driver to use new macros for checking caps.

net/mlx5_core: HW data structs/types definitions cleanup

2015-05-31T01:23:11+00:00

mlx5_ifc.h was heavily modified here since it is now generated by a
script from the device specification (PRM rev 0.25). This specification
is backward compatible to existing hardware.

Some structures/fields were added here in order to enable the Ethernet
functionality of the driver.

IB/mlx5: Add mlx5_ib_update_mtt to update page tables after creation

2014-12-16T02:19:02+00:00

The new function allows updating the page tables of a memory region
after it was created. This can be used to handle page faults and page
invalidations.

Since mlx5_ib_update_mtt will need to work from within page invalidation,
so it must not block on memory allocation. It employs an atomic memory
allocation mechanism that is used as a fallback when kmalloc(GFP_ATOMIC) fails.

In order to reuse code from mlx5_ib_populate_pas, the patch splits
this function and add the needed parameters.

IB/mlx5: Changes in memory region creation to support on-demand paging

2014-12-16T02:19:02+00:00

This patch wraps together several changes needed for on-demand paging support
in the mlx5_ib_populate_pas function, and when registering memory regions.

* Instead of accepting a UMR bit telling the function to enable all
  access flags, the function now accepts the access flags themselves.
* For on-demand paging memory regions, fill the memory tables from the
  correct list, and enable/disable the access flags per-page according
  to whether the page is present.
* A new bit is set to enable writing of access flags when using the
  firmware create_mkey command.
* Disable contig pages when on-demand paging is enabled.

In addition the patch changes the UMR code to use PTR_ALIGN instead of
our own macro.

mlx5_core: Add support for page faults events and low level handling

2014-12-16T02:18:59+00:00

* Add a handler function pointer in the mlx5_core_qp struct for page
  fault events. Handle page fault events by calling the handler
  function, if not NULL.
* Add on-demand paging capability query command.
* Export command for resuming QPs after page faults.
* Add various constants related to paging support.

mlx5_core: Re-add MLX5_DEV_CAP_FLAG_ON_DMND_PG flag

2014-12-16T02:18:58+00:00

In commit 0c7aac854f52 ("net/mlx5_core: Remove unused dev cap enum
fields"), the flag MLX5_DEV_CAP_FLAG_ON_DMND_PG was removed.
Unfortunately the on-demand paging changes actually use it, so re-add
the missing flag.
