RDMA/rxe: Fix coding error in rxe_recv.c · 7d9ae80e

Bob Pearson authored Jan 27, 2021

check_type_state() in rxe_recv.c is written as if the type bits in the
packet opcode were a bit mask which is not correct. This patch corrects
this code to compare all 3 type bits to the required type.

IB/mlx5: Use rdma_for_each_port for port iteration · 13179652

Parav Pandit authored Feb 03, 2021

Instead of open coding the loop for port iteration, use rdma_for_each_port
macro provided by core.

To use such macro, early initialization of phys_port_cnt is needed.
Hence, initialize such constant early enough in the init stage.

Whichever functions are called with port using rdma_for_each_port(),
convert their port type from u8 to unsigned int to match the core API.

RDMA/core: Introduce and use API to read port immutable data · 7416790e

Parav Pandit authored Feb 03, 2021

Currently mlx5 driver caches port GID table length for 2 ports. It is
also cached by IB core as port immutable data.

When mlx5 representor ports are present, which are usually more than 2,
invalid access to port_caps array can happen while validating the GID
table length which is only for 2 ports.

To avoid this, take help of the IB cores port immutable data by exposing
an API to read the port immutable fields.

Remove mlx5 driver's internal cache, thereby reduce code and data.

IB/mlx5: Improve query port for representor port · 7a58779e

Parav Pandit authored Feb 03, 2021

Improve query port functionality for representor port as below.

1. RoCE Qkey violation counters are not applicable for representor port.
2. Avoid setting gid_tbl_len twice for representor port.
3. Avoid setting ip_gids and IB_PORT_CM_SUP property for representor port
as GID table is empty and CM support is not present in representor
mode.

IB/mlx5: Avoid calling query device for reading pkey table length · 2019d70e

Parav Pandit authored Feb 03, 2021

Pkey table length for all the ports of the device is the same. Currently
get_ports_cap() reads and stores it for each port by querying the device
which reads more than just pkey table length.

For representor device ports which can be in range of hundreds, it queries
is for each such port and end up returning same value for all the ports.

When in representor mode, modify QP accesses pkey port caps for a port
index that can be outside of the port_caps table.

Hence, simplify the logic to query the max pkey table length only once
during device initialization sequence.

reduce the scope of it to multiple drivers.

RDMA/rxe: Remove unneeded pool->state · eae5f064

Bob Pearson authored Jan 25, 2021

rxe_pool.c uses the field pool->state to mark a pool as invalid when it is
shut down and checks it in several pool APIs to verify that the pool has
not been shut down. This is unneeded because the pools are not marked
invalid unless the entire driver is being removed at which point no
functional APIs should or could be executing. This patch removes this
field and associated code.

RDMA/rxe: Remove references to ib_device and pool · 6cde3e8e

Bob Pearson authored Jan 25, 2021

rxe_pool.c takes references to the pool and ib_device structs for each
object allocated and also keeps an atomic num_elem count in each
pool. This is more work than is needed. Pool allocation is only called
from verbs APIs which already have references to ib_device and pools are
only diasbled when the driver is removed so no protection of the pool
addresses are needed. The elem count is used to warn if elements are still
present in a pool when it is cleaned up which is useful.

This patch eliminates the references to the ib_device and pool structs.
