I don't understand,
On the second patch of this series you detect the HVA_IBV_DEVX_OBJ according to:
+ [ 'HAVE_IBV_DEVX_OBJ', 'infiniband/mlx5dv.h',
+ 'mlx5dv_devx_obj_create' ],
Typo?

This commit fixes the logic for searching and allocating a shared
counter in mlx5_flow_verbs.
Now only the shared counters in the counters list are checked for
a match and not all the counters as before.
Fixes: 84c406e74524 ("net/mlx5: add flow translate function")

Moti, don't you forget to update flow_verbs_counter_release() ?
Only shared counters should be removed from the list.
WBR,

+1, thanks slava.
Moti, I have no more comments on this series.

Hi,
Every counter that is created (shared or not) is added to the counters list
Therefore every counter destined for removal (i.e. ref_count == 0) should also be
Removed from this list.
What am I missing ?

This patch adds glue functions for operations:
- dv_open_device.
- devx object create, destroy, query and modify.
- devx general command
The new operations depend on HAVE_IBV_DEVX_OBJ.

From: Mordechay Haimovsky @ 2018-12-27 22:20 UTC (permalink / raw)
To: dev; +Cc: Mordechay Haimovsky
This commit adds counters support when creating flows via direct
verbs. The implementation uses devx interface in order to create
query and delete the counters.
This support requires MLNX_OFED_LINUX-4.5-0.1.0.1 installation.

This patch adds glue functions for operations:
- dv_open_device.
- devx object create, destroy, query and modify.
- devx general command
The new operations depend on HAVE_IBV_DEVX_OBJ.

This commit fixes the logic for searching and allocating a shared
counter in mlx5_flow_verbs.
Now only the shared counters in the counters list are checked for
a match and not all the counters as before.
Fixes: 84c406e74524 ("net/mlx5: add flow translate function")

This commit adds counters support when creating flows via direct
verbs. The implementation uses devx interface in order to create
query and delete the counters.
This support requires MLNX_OFED_LINUX-4.5-0.1.0.1 installation.

Series applied to next-net-mlx, thanks.
Moti - please notice your author name and singed-of name are not aligned.
I fixed it for this series, please update your gitconfig for them to match on the next patches.

This commit fixes the logic for searching and allocating a shared
counter in mlx5_flow_verbs.
Now only the shared counters in the counters list are checked for
a match and not all the counters as before.
Fixes: 84c406e74524 ("net/mlx5: add flow translate function")

This patch adds glue functions for operations:
- dv_open_device.
- devx object create, destroy, query and modify.
- devx general command
The new operations depend on HAVE_IBV_DEVX_OBJ.

This commit adds counters support when creating flows via direct
verbs. The implementation uses devx interface in order to create
query and delete the counters.
This support requires MLNX_OFED_LINUX-4.5-0.1.0.1 installation.
