alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces deprecated create_singlethread_workqueue(). This is the identity conversion. The workqueue "mcast_wq" queues work item &group->work. It has been identity converted. WQ_MEM_RECLAIM has been set to ensure forward progress under memory pressure. Signed-off-by:

When LAG is active, port up/down events should be triggered by tracking the LAG master, and not one of the two slave netdevs. In the same manner, ib_query_port() should return the details of the LAG master. Signed-off-by:

Aviv Heller authored
This is done in two steps: 1) Issuing CREATE_VPORT_LAG in order to have Ethernet traffic from both ports arriving on PF0 root flowtable, so we will be able to catch all raw-eth traffic on PF0. 2) Creation of LAG demux flowtable in order to direct all non-raw-eth traffic back to its source port, assuring that normal Ethernet traffic "jumps" to the root flowtable of its RX port (non-LAG behavior).

Since ib_query_port() in RoCE returns the state of its netdev as the port state, it makes sense to propagate the port up/down events to ib_core when the netdev port state changes, instead of relying on traditional core events. This also keeps both the event and ib_query_port() synchronized. Signed-off-by:

Flow steering specifications structures were implemented as in an extensible way that allows one to add new filters and new fields to existing filters. These specifications have never been extended, therefore the kernel flow specifications size and the user flow specifications size were must to be equal. In downstream patch, the IPv4 flow specifications type is extended to support TOS and TTL fields. To support an extension we change the flow specifications size condition test to be as following: * If the user flow specifications is bigger than the kernel specifications, we verify that all the bits which not in the kernel specifications are zeros and the flow is added only with the kernel specifications fields. * Otherwise, we add flow rule only with the user specifications fields. User space filters must be aligned with 32bits. Signed-off-by:

Counters weren't updated due to raw packet QPs' traffic since the counter-id was not associated with the QP. Added support for associating the q-counter-id with the raw packet QP. The attachment is done only when changing RQ raw packet QP state from RST to INIT in modify-RQ command. FW support is required for the above, without this support raw packet QP counters will not count. Signed-off-by:

Expose RSS related capabilities on both IB and vendor channels. In addition to the IB capabilities the driver reports some extra capabilities on its vendor channel: - Bit mask of the supported types of hash functions. - Bit mask of the supported RX fields that can participate in the RX hashing. Those capabilities are applicable only when the link layer is Ethernet. Signed-off-by:

We now only use it from ib_alloc_pd to create a local DMA lkey if the device doesn't provide one, or a global rkey if the ULP requests it. This patch removes ib_get_dma_mr and open codes the functionality in ib_alloc_pd so that we can simplify the code and prevent abuse of the functionality. As a side effect we can also simplify things by removing the valid access bit check, and the PD refcounting. In the future I hope to also remove the per-PD global MR entirely by shifting this work into the HW drivers, as one step towards avoiding the struct ib_mr overload for various different use cases.

Instead of exposing ib_get_dma_mr to ULPs and letting them use it more or less unchecked, this moves the capability of creating a global rkey into the RDMA core, where it can be easily audited. It also prints a warning everytime this feature is used as well. Signed-off-by:

Christoph Hellwig authored
This has two reasons: a) to clearly mark that drivers don't have any business using it, and b) because we're going to use it for the (dangerous) global rkey soon, so that drivers don't create on themselves. Signed-off-by:

This patch is meant to add support of ACPI to the Hisilicon RoCE driver. Changes done are primarily meant to detect the type and then either use DT specific or ACPI spcific functions. Where ever possible, this patch tries to make use of Unified Device Property Interface APIs to support both DT and ACPI through single interface. This patch depends upon HNS ethernet driver to Reset RoCE. This function within HNS ethernet driver has also been enhanced to support ACPI and is part of other accompanying patch with this patch-set. NOTE: The changes in this patch are done over below branch, https://github.com/dledford/linux/tree/hns-roceSigned-off-by:

In the Hip06 SoC, the RoCE Engine is part of the Hisilicon Network Subsystem and is dependent upon DSAF module. Therefore, certain functions like RESET are exposed through the common registers of HNS DSAF module which are memory-mapped by the HNS driver and currently can only be accessed through DT/syscon interface. This patch adds the support of ACPI to the existing RoCE reset function in the HNS driver(please refer NOTE 2). Hisilicon RoCE driver (please refer NOTE 1) shall call this reset function during probe time to reset the RoCE Engine. The HNS Reset function indirectly ends up in calling the _DSM() function part of the DSDT ACPI Table. Actual reset functionality for ACPI is implemented within the ACPI DSDT Table which also has been enhanced to support this change. Support of ACPI in the HNS RoCE driver shall be pushed through a different accompanying below patch: "IB/hns: Add support of ACPI to the Hisilicon RoCE Driver" NOTE 1: HNS RoCE driver has already been accepted by its maintainer Doug Ledford<dledford@redhat.com>. Please refer below link: https://www.spinics.net/lists/linux-rdma/msg38850.html NOTE 2: RoCE reset function patch has been accepted and now is part of the net-next: https://www.mail-archive.com/netdev@vger.kernel.org/msg123867.htmlSigned-off-by:
