2024-07-01RDMA/mlx5: Support per-plane port IB counters by querying PPCNT registerMark Zhang1-11/+58

2024-07-01RDMA/mlx5: Support plane device and driver APIs to add and delete itMark Zhang1-1/+1
This patch supports driver APIs "add_sub_dev" and "del_sub_dev", to add and delete a plane device respectively. A mlx5 plane device is a rdma SMI device; It provides the SMI capability through user MAD for it's parent, the logical multi-plane aggregated device. For a plane port: - It supports QP0 only; - When adding a plane device, all plane ports are added; - For some commands like mad_ifc, both plane_index and native portnum is needed; - When querying or modifying a plane port context, the native portnum must be used, as the query/modify_hca_vport_context command doesn't support plane port.

2021-03-26RDMA: Support more than 255 rdma portsMark Bloch1-8/+8
Current code uses many different types when dealing with a port of a RDMA device: u8, unsigned int and u32. Switch to u32 to clean up the logic. This allows us to make (at least) the core view consistent and use the same type. Unfortunately not all places can be converted. Many uverbs functions expect port to be u8 so keep those places in order not to break UAPIs. HW/Spec defined values must also not be changed. With the switch to u32 we now can support devices with more than 255 ports. U32_MAX is reserved to make control logic a bit easier to deal with. As a device with U32_MAX ports probably isn't going to happen any time soon this seems like a non issue. When a device with more than 255 ports is created uverbs will report the RDMA device as having 255 ports as this is the max currently supported. The verbs interface is not changed yet because the IBTA spec limits the port size in too many places to be u8 and all applications that relies in verbs won't be able to cope with this change. At this stage, we are extending the interfaces that are using vendor channel solely Once the limitation is lifted mlx5 in switchdev mode will be able to have thousands of SFs created by the device. As the only instance of an RDMA device that reports more than 255 ports will be a representor device and it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other ULPs aren't effected by this change and their sysfs/interfaces that are exposes to userspace can remain unchanged.

Hence, initialize such constant early enough in the init stage.

2021-02-05IB/mlx5: Avoid calling query device for reading pkey table lengthParav Pandit1-1/+1
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.

2019-07-03IB/mlx5: Fixed reporting counters on 2nd port for Dual port RoCEParav Pandit1-24/+36
Currently during dual port IB device registration in below code flow, ib_register_device() ib_device_register_sysfs() ib_setup_port_attrs() add_port() get_counter_table() get_perf_mad() process_mad() mlx5_ib_process_mad() mlx5_ib_process_mad() fails on 2nd port when both the ports are not fully setup at the device level (because 2nd port is unaffiliated). As a result, get_perf_mad() registers different PMA counter group for 1st and 2nd port, namely pma_counter_ext and pma_counter. However both ports have the same capability and counter offsets. Due to this when counters are read by the user via sysfs in below code flow, counters are queried from wrong location from the device mainly from PPCNT instead of VPORT counters. show_pma_counter() get_perf_mad() process_mad() mlx5_ib_process_mad() process_pma_cmd() This shows all zero counters for 2nd port. To overcome this, process_pma_cmd() is invoked, and when unaffiliated port is not yet setup during device registration phase, make the query on the first port. while at it, only process_pma_cmd() needs to work on the native port number and underlying mdev, so shift the get, put calls to where its needed inside process_pma_cmd().

2015-06-12IB/mad: Add support for additional MAD info to/from driversIra Weiny1-1/+8
In order to support alternate sized MADs (and variable sized MADs on OPA devices) add in/out MAD size parameters to the process_mad core call. In addition, add an out_mad_pkey_index to communicate the pkey index the driver wishes the MAD stack to use when sending OPA MAD responses. The out MAD size and the out MAD PKey index are required by the MAD stack to generate responses on OPA devices. Furthermore, the in and out MAD parameters are made generic by specifying them as ib_mad_hdr rather than ib_mad. Drivers are modified as needed and are protected by BUG_ON flags if the MAD sizes passed to them is incorrect.

2015-06-04IB/mlx5: Avoid using the MAD_IFC command under ISSI > 0 modeMajd Dibbiny1-0/+297
In ISSI > 0 mode, most of the MAD_IFC command features are deprecated, and can't be used. Therefore, when in that mode, we replace all of them with other commands that provide the required functionality.

2015-06-02IB/core cleanup: Add const on args - device->process_madIra Weiny1-4/+4
The process_mad device function declares some parameters as "in". Make those parameters const and adjust the call tree under process_mad in the various drivers accordingly.

2015-05-30net/mlx5_core: New device capabilities handlingSaeed Mahameed1-1/+1
- 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.

Rearrange struct mlx5_caps so it has a "gen" field to represent the current capabilities configured for the device. Max capabilities can also be queried from the device. Also update capabilities struct to contain more fields as per the latest revision if firmware specification. Signed-off-by: Eli Cohen <[email protected]> Signed-off-by: David S.

2014-07-30mlx5: minor fixes (mainly avoidance of hidden casts)Jack Morgenstein1-1/+1
There were many places where parameters which should be u8/u16 were integer type. Additionally, in 2 places, a check for a non-null pointer was added before dereferencing the pointer (this is actually a bug fix).
