From: Daniel Jurgens Date: Fri, 12 Jul 2024 00:33:07 +0000 (-0700) Subject: net/mlx5: IFC updates for SF max IO EQs X-Git-Tag: io_uring-6.11-20240722~71^2~30^2~3 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=63c6e08eac8e7e2ad2e883c968e58e23e1dc8c70;p=linux-2.6-block.git net/mlx5: IFC updates for SF max IO EQs Expose a new cap sf_eq_usage. The vhca_resource_manager can write this cap, indicating the SF driver should use max_num_eqs_24b to determine how many EQs to use. Will be used in the next patch, to indicate to the SF driver from the PF that the user has set the max io eqs via devlink. So the SF driver can later query the proper max eq value from the new cap. devlink port function set pci/0000:08:00.0/32768 max_io_eqs 32 Signed-off-by: Daniel Jurgens Reviewed-by: William Tu Signed-off-by: Tariq Toukan Signed-off-by: Saeed Mahameed Link: https://patch.msgid.link/20240712003310.355106-2-saeed@kernel.org Signed-off-by: Jakub Kicinski --- diff --git a/include/linux/mlx5/mlx5_ifc.h b/include/linux/mlx5/mlx5_ifc.h index fdad0071d599..360d42f041b0 100644 --- a/include/linux/mlx5/mlx5_ifc.h +++ b/include/linux/mlx5/mlx5_ifc.h @@ -1994,7 +1994,9 @@ struct mlx5_ifc_cmd_hca_cap_2_bits { u8 migration_tracking_state[0x1]; u8 reserved_at_ca[0x6]; u8 migration_in_chunks[0x1]; - u8 reserved_at_d1[0xf]; + u8 reserved_at_d1[0x1]; + u8 sf_eq_usage[0x1]; + u8 reserved_at_d3[0xd]; u8 cross_vhca_object_to_object_supported[0x20];
