net/mlx5: fix RETA update without stopping device

The global redirection table is used to create the default flow
rules for the ingress traffic with the lowest priority. It is also
used to create the default RSS rule in the destination table when
there is a tunnel offload.

To update the RETA in-flight, there is no restriction in the ethdev
API. In the previous implementation of mlx5, a port restart was
needed to make the new configuration take effect.

The restart is heavy, e.g., all the queues will be released and
reallocated, users' rules will be flushed. Since the restart is
internal, there is a risk to crash the application when some change
in the ethdev is introduced but no workaround is done in mlx5 PMD.

The users' rules, including the default miss rule for tunnel
offload, should not be impacted by the RETA update. It is improper
to flush all rules when updating RETA.

With this patch, only the default rules will be flushed and
re-created with the new table configuration.

The purpose of this list is to provide a buffer in CPU memory visible
from the GPU that can be treated as a circular buffer
to let the CPU provide fondamental info of received packets to the GPU.

CPU:
- Trigger some task on the GPU
- in a loop:
    - receive a number of packets
    - provide packets info to the GPU

GPU:

- Wait to receive a new set of packet to be processed

  - as regular cached memory, the variable is either missing or set to

    register writing latency and requires an explicit memory write
    barrier to mitigate this issue and prevent write combining.

  - as non-cached memory, the variable is present and set to not "0"
    value. This type of mapping may cause performance impact under
    heavy loading conditions but the explicit write memory barrier is
    not required and it may improve core performance.

The UAR creation function maps a doorbell in one of the above ways
according to the system. In run time, it always adds an explicit memory
barrier after writing to.
In cases where the doorbell was mapped as non-cached memory, the
explicit memory barrier is unnecessary and may impair performance.

The commit [1] solved this problem for a Tx queue. In run time, it
checks the mapping type and provides the memory barrier after writing to
a Tx doorbell register if it is needed. The mapping type is extracted
directly from the uar_mmap_offset field in the queue properties.

common/mlx5: make multi-process MR management port-agnostic

In the multi-process mechanism, there are things that the secondary
process does not perform itself but asks the primary process to perform
for it.
There is a special API for communication between the processes that
receives parameters necessary for the specific action required as well
as a special structure called mp_id that contains the port number of the
processes through which the initial process finds the relevant ETH
device for the processes.

One of the operations performed through this mechanism is the creation
of a memory region, where the secondary process sends the virtual
address as a parameter and the mp_id structure with the port number
inside it.
However, once the memory area management is shared between the drivers
and either port number or ETH device is no longer relevant to them, it
seems unnecessary to continue communicating between the processes
through the mp_id variable.

In this patch we will remove the use of the above structure for all MR
management, and add to the specific parameter of operations a pointer to
the common device that contains everything needed to create/register MR.

3 years agocommon/mlx5: remove redundant parameter in MR search

common/mlx5: remove redundant parameter in MR search

Memory region management has recently been shared between drivers,
including the search for caches in the data plane.
The initial search in the local linear cache of the queue, usually
yields a result and one should not continue searching in the next level
caches.

The function that searches in the local cache gets the pointer to a
device as a parameter, that is not necessary for its operation
but for subsequent searches (which, as mentioned, usually do not
happen).
Transferring the device to a function and maintaining it, takes some
time and causes some impact on performance.

Add the pointer to the device as a field of the mr_ctrl structure. The
field will be updated during control path and will be used only when
needed in the search.
