Or Gerlitz says: ==================== mlx5e-pedit 2017-03-28 This series adds support for offloading modifications of packet headers using ConnectX-5 HW header re-write as an action applied during packet steering. The offloaded SW mechanism is TC's pedit action. The offloading is supported for E-Switch steering of VF traffic in the SRIOV switchdev mode and for NIC (non eswitch) RX. One use-case for this offload on virtual networks, is when the hypervisor implements flow based router such as Open-Stack's DVR, where L2 headers of guest packets re-written with routers' MAC addresses and the IP TTL is decremented. Another use case (which can be applied in parallel with routing) is stateless NAT where guest L3/L4 headers are re-written. The series is built as follows: the 1st six patches are preperations which don't yet add new functionality, patches 7-8 add the FW APIs (data-structures and commands) for header re-write, and patch nine allows offloading driver to access pedit keys. The 10th patch is somehow the core of the series, where we translate from the pedit way to represent set of header modification elements to the FW API for that same matter. Once a set of HW modification is established, we register it with the FW and get a modify header ID. When this ID is used with an action during packet steering, the HW applies the header modification on the packet. Patches 11 and 12 implement the above logic as an offload for pedit action for the NIC and E-Switch use-cases. I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing and helping me testing this functionality on HW simulator, before it could be done with FW. ==================== Signed-off-by:David S.

mdio-boardinfo contains code that is helpful for platforms to register specific MDIO bus devices independent of how CONFIG_MDIO_DEVICE or CONFIG_PHYLIB will be selected (modular or built-in). In order to make that possible, let's do the following: - descend into drivers/net/phy/ unconditionally - make mdiobus_setup_mdiodev_from_board_info() take a callback argument which allows us not to expose the internal MDIO board info list and mutex, yet maintain the logic within the same file - relocate the code that creates a MDIO device into drivers/net/phy/mdio_bus.c - build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is defined (y or m) Fixes: 90eff909 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Fixes: 648ea013 ("net: phy: Allow pre-declaration of MDIO devices") Signed-off-by:

Andrew Lunn says: ==================== break include loop and dsa devlink support These two patches add very basic support for devlink to DSA, in preparation for playing with dpipe. The first patch is needed to break an include loop between netdevice.h, dsa.h and devlink.h. We need to remove dsa.h from netdevice.h. As a result, some files fail to compile, because they require includes pulled in via dsa.h. So this patch adds a number of includes in various places. The majority is within the network subsystem, but cifs also needs a few fixes. 0-day has been chewing on this for over a day now, and not found any breakage. But Arnd's randconfig might uncover something. ==================== Signed-off-by: -

There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.

Refactor interrupt moderation code for flexibility because parameters are different for 10G and 25G cards. Currently parameters (for 10G only) come from macros compiled-in to the PF and VF drivers; fix it so that parameters suitable for the card (10G or 25G) come from the NIC firmware via response to a command. Also bump up driver version to 1.5.1 to match newer NIC firmware version. Signed-off-by:

Yuval Mintz says: ==================== qed: load/unload mfw series This series correct the unload flow and greatly enhances its initialization flow in regard to interactions between driver and management firmware. Patch #1 makes sure unloading is done under management-firmware's 'criticial section' protection. Patches #2 - #4 move driver into using a newer scheme for loading in regard to the MFW; This newer scheme would help cleaning the device in case a previous instance has dirtied it [preboot, PDA, etc.]. Patches #5 - #6 let driver inform management-firmware on number of resources which are dependent on the non-management firmware used. Patch #7 then uses a new resource [BDQ] instead of some set value. ==================== Signed-off-by: -

Management firmware is used as an arbiter between the various PFs in matters of resources, but some of the resources that need to be divided are dependent on the non-management firmware used, so management firmware first needs to be told how many resources there are before trying to divide them. As part of the initialization sequence, driver would first inform the management firmware of the available resources under a dedicated resource lock, and afterwards request for various resources which might be based on the previous set values.

Global locking can't properly be used to synchronize between different PFs in all scenarios, as those instances might reside in different logical partitions [e.g., when a PF is assigned via PDA to some VM]. The management firmware provides a generic infrastructure for device locks. For each 'resource', it's guaranteed it could be acquired by at most a single PF at any given time [or by management firmware]. This patch adds the necessary logic in qed for utilizing said infrastructure, implementing lock/unlock internal APIs. Signed-off-by:

During HW initialization, driver would set various registers to their needed values - but it assumes all registers start at their reset-value, so there's no need to re-configure a register's default value. This assumption might be incorrect, e.g., in case of preboot driver running and initializing the driver prior to our driver. To overcome this, we now ask management firmware to initiate a PF-flr early during the initialization sequence. That would return everything in the PF's scope back to default and prevent previous configurations from still being applied. Signed-off-by:

Management firmware is used as an arbiter between the various PFs in regard to loading - it causes the various PFs to load/unload sequentially and informs each of its appropriate rule in the init. But the existing flow is too weak to handle some scenarios where PFs aren't properly cleaned prior to loading. The significant scenarios falling under this criteria: a. Preboot drivers in some environment can't properly unload. b. Unexpected driver replacement [kdump, PDA]. Modern management firmware supports a more intricate loading flow, where the driver has the ability to overcome previous limitations. This moves qed into using this newer scheme. Notice new scheme is backward compatible, so new drivers would still be able to load properly on top of older management firmwares and vice versa. Signed-off-by:

Management firmware is used as arbiter between different PFs which are loading/unloading, but in order to use the synchronization it offers the contending configurations need to be applied either between their LOAD_REQ <-> LOAD_DONE or UNLOAD_REQ <-> UNLOAD_DONE management firmware commands. Existing HW stop flow utilizes 2 different functions: qed_hw_stop() and qed_hw_reset() which don't abide this requirement; Most of the closure is doing outside the scope of the unload request. This patch removes qed_hw_reset() and places the relevant stop functionality underneath the management firmware protection. Signed-off-by:

Parthasarathy Bhuvaragan says: ==================== tipc: subscription refcount simplifications The first patch makes the subscription refcount cleanup lockless and the second updates the subscription refcount policy. ==================== Signed-off-by: -
Ying Xue authored
When a new subscription object is inserted into name_seq->subscriptions list, it's under name_seq->lock protection; when a subscription is deleted from the list, it's also under the same lock protection; similarly, when accessing a subscription by going through subscriptions list, the entire process is also protected by the name_seq->lock. Therefore, if subscription refcount is increased before it's inserted into subscriptions list, and its refcount is decreased after it's deleted from the list, it will be unnecessary to hold refcount at all before accessing subscription object which is obtained by going through subscriptions list under name_seq->lock protection.

After a subscription object is created, it's inserted into its subscriber subscrp_list list under subscriber lock protection, similarly, before it's destroyed, it should be first removed from its subscriber->subscrp_list. Since the subscription list is accessed with subscriber lock, all the subscriptions are valid during the lock duration. Hence in tipc_subscrb_subscrp_delete(), we remove subscription get/put and the extra subscriber unlock/lock. After this change, the subscriptions refcount cleanup is very simple and does not access any lock. Acked-by:

By moving these client drivers to use RPMSG instead of the direct SMD API we can reuse them ontop of the newly added GLINK wire-protocol support found in the 820 and 835 Qualcomm platforms. As the new (RPMSG-based) and old SMD implementations are mutually exclusive we have to change all client drivers in one commit, to make sure we have a working system before and after this transition.

Jiri Pirko says: ==================== Add support for pipeline debug (dpipe) Arkadi says: While doing the hardware offloading process much of the hardware specifics cannot be presented. An example for such is the routing LPM algorithm which differ in hardware implementation from the kernel software implementation. The only information the user receives is whether specific route is offloaded or not, but he cannot really understand the underlying implementation nor get the specific statistics related to that process. Another example is ACL offload using TC which is commonly implemented using TCAM memory. Currently there is no capability to gain visibility into the TCAM structure and to debug suboptimal resource allocation. This patchset introduces capability for exporting the ASICs pipeline abstraction via devlink infrastructure, which should serve as an complementary tool. This infrastructure allows the user to get visibility into the ASIC by modeling it as a set of match/action tables. The main objects defined: Table - abstraction for a single pipeline stage. Contains the available match/actions and counter availability. Entry - entry in a specific table with specific matches/actions values and dedicated counter. Header/field - tuples which describes the tables behavior. As an example one of the ASIC's L3 blocks will be modeled. The egress rif (router interface) table is the final step in the L3 pipeline processing which does match on the internal rif index which was determined before by the routing logic. The erif table determines whether to forward or drop the packet and updates the corresponding rif L3 statistics. To expose this internal resources a special metadata header will be introduced that describes the internal information gathered by the ASIC's pipeline and contains the following fields: rif_port_index, forward and drop. Some internal hardware resources have direct mapping to kernel objects. For example the rif_port_index is mapped to the net-devices ifindex. By providing this mapping the users gains visibility into the offloading process. Follow-up work will include exporting more L3 tables which will give visibility into the routing process. First stage is adding support for dpipe in devlink. Next add support in spectrum driver. Finally implement egress router interface (erif) table for spectrum ASIC as an example. --- v1->v2: Please see individual patches ==================== Signed-off-by:
