Insteadof calculating everytime, read directly from eswitch.Additionally, host PF's SF vport information is available usingQUERY_HCA_CAP command. It is not available through HCA_CAP of theeswitch manager PF.Hence, this patch prepares the return total eswitch vport count from theexisting eswitch struct.This further helps to keep eswitch port counting macros and logic withineswitch.Signed-off-by: Parav Pandit Reviewed-by: Roi Dayan Signed-off-by: Saeed Mahameed List of files: /linux-6.15/include/linux/mlx5/vport.h

net/mlx5: E-Switch, Assign a different position for uplink rep and vportIn offloads mode, the current implementation puts the uplinkrepresentor at index zero of the vport reps array. It is not "natural"to place it at index 0 since we want to put the representor for vport0 at index 0 with the introduction of SmartNIC. A separate patch willhandle the case whether a rep is needed for vport 0 (PF vport).So, we want to have a different placeholder for uplink vport andrepresentor. It was placed at the end of vport and rep array. Sincevport number can no longer act as an index into the vport orrepresentors arrays, use functions to map vport numbers to indiceswhen accessing the vports or representors arrays, and vice versa.Signed-off-by: Bodong Wang Signed-off-by: Eli Cohen Reviewed-by: Or Gerlitz Signed-off-by: Saeed Mahameed List of files: /linux-6.15/include/linux/mlx5/vport.h

c9b99abc - net/mlx5: E-Switch, Split VF and special vports for offloads mode

Thu, 31 Jan 2019 20:40:53 +0000

net/mlx5: E-Switch, Split VF and special vports for offloads modeWhen driver is entering offloads mode, there are two major tasks todo: initialize flow steering and create representors. Flow steeringshould make sure enough flow table/group spaces are reserved for allreps. Representors will be created in a group, all or none.With the introduction of ECPF, flow steering should still reserve thesame spaces. But, the representors are not always loaded/unloaded in asingle piece. Once ECPF is in offloads mode, it will get the numberof VF changing event from host PF. In such scenario, only the VF repsshould be loaded/unloaded, not the reps for special vports (such asthe uplink vport).Thus, when entering offloads mode, driver should specify the totalnumber of reps, and the number of VF reps separately. When leavingoffloads mode, the cleanup should use the information self-containedin eswitch such as number of VFs.This patch doesn't change any functionality.Signed-off-by: Bodong Wang Reviewed-by: Or Gerlitz Signed-off-by: Saeed Mahameed List of files: /linux-6.15/include/linux/mlx5/vport.h

Fri, 01 Feb 2019 23:34:55 +0000

net/mlx5: E-Switch, Properly refer to host PF vport as other vportCommands referring to vports use the following scheme:1. When referring to my own vport, put 0 in vport and 0 in other_vport.2. When referring to another vport, put the vport number of the referred vport and put 1 in other_vport. It was assumed that driver is accessing other vport when vport number is greater than 0.With the above scheme, the case that ECPF eswitch manager is tryingto access host PF vport will fall over with scheme 1 as the vportnumber is 0. This is apparently wrong as driver is trying to referother vport.As such usage can only happen in the eswitch context, change relevantfunctions to provide other vport input properly.Signed-off-by: Bodong Wang Signed-off-by: Eli Cohen Signed-off-by: Saeed Mahameed List of files: /linux-6.15/include/linux/mlx5/vport.h

net/mlx5: E-Switch, Avoid magic numbers when initializing offloads modeWhen dealing with the offloads mode initialization, driver refers tothe number of VFs and add magic number one (1) to take account of theuplink. This is not clear and will make the code less readable afteradding other vports (e.g. host PF). As these are special vportscompared to VF vports, add a helper macro to denote such specialvports and eliminate the use of magic number.Moreover, when creating offloads flow table and groups, the driverreserves two more slots for UC and MC miss rules.
