2018-10-30net: mvpp2: Fix affinity hint allocationMarc Zyngier2-4/+15
The mvpp2 driver has the curious behaviour of passing a stack variable to irq_set_affinity_hint(), which results in the kernel exploding the first time anyone accesses this information. News flash: userspace does, and irqbalance will happily take the machine down. Great stuff. An easy fix is to track the mask within the queue_vector structure, and to make sure it has the same lifetime as the interrupt itself.

2018-10-23octeontx2-af: Support for NIXLF's UCAST/PROMISC/ALLMULTI modesSunil Goutham4-1/+105
By default NIXLF is set in UCAST mode. This patch adds a new mailbox message which when sent by a RVU PF changes this default mode. When promiscuous mode is needed, the reserved promisc entry for each of RVU PF is setup to match against ingress channel number only, so that all pkts on that channel are accepted and forwarded to the mode change requesting PF_FUNC's NIXLF. PROMISC and ALLMULTI modes are supported only for PFs, for VFs only UCAST mode is supported. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-10-23octeontx2-af: Support for changing RSS algorithmSunil Goutham4-1/+108
This patch adds support for a RVU PF/VF to change NIX Rx flowkey algorithm index in NPC RX RSS_ACTION. eg: a ethtool command changing RSS algorithm for a netdev interface would trigger this change in NPC. If PF/VF doesn't specify any MCAM entry index then default UCAST entry of the NIXLF attached to PF/VF will be updated with RSS_ACTION and flowkey index.

2018-10-23octeontx2-af: NIX Rx flowkey configuration for RSSSunil Goutham3-0/+187
Configure NIX RX flowkey algorithm configuration to support RSS (receive side scaling). Currently support for only L3/L4 2-tuple and 4-tuple hash of IPv4/v6/TCP/UDP/SCTP is added. HW supports upto 32 different flowkey algorithms which SW can define, this patch defines 9. NPC RX ACTION has to point to one of these flowkey indices for RSS to work. The configuration is dependent on NPC parse result's layer info. So if NPC KPU profile changes suchthat LID/LTYPE values of above said protocols change then this configuration will most likely be effected.

2018-10-23octeontx2-af: NPC MCAM and LDATA extract minimal configurationSunil Goutham4-0/+181
This patch adds some minimal configuration for NPC MCAM and LDATA extraction which is sufficient enough to install ucast/bcast/promiscuous forwarding rules. Below is the config done - LDATA extraction config to extract DMAC from pkt to offset 64bit in MCAM search key. - Set MCAM lookup keysize to 224bits - Set MCAM TX miss action to UCAST_DEFAULT - Set MCAM RX miss action to DROP Also inorder to have guaranteed space in MCAM to install ucast forwarding rule for each of RVU PF/VF, reserved one MCAM entry for each of NIXLF for ucast rule. And two entries for each of RVU PF. One for bcast pkt replication and other for promiscuous mode which allows all pkts received on a HW CGX/LBK channel.

2018-10-23octeontx2-af: NIX Tx scheduler queue config supportSunil Goutham5-5/+199
This patch adds support for a PF/VF driver to configure NIX transmit scheduler queues via mbox. Since PF/VF doesn't know the absolute HW index of the NIXLF attached to it, AF traps the register config and overwrites with the correct NIXLF index. HW supports shaping, colouring and policing of packets with these multilevel traffic scheduler queues. Instead of introducing different mbox message formats for different configurations and making both AF & PF/VF driver implementation cumbersome, access to the scheduler queue's CSRs is provided via mbox. AF checks whether the sender PF/VF has the corresponding queue allocated or not and dumps the config to HW. With a single mbox msg 20 registers can be configured.

For setting up pkt transmission priorities between queues, the scheduler queues have to be contiguous w.r.t their HW indices. So both contiguous and non-contiguous allocations are supported.

2018-10-10octeontx2-af: Add Marvell OcteonTX2 CGX driverSunil Goutham4-2/+133
This patch adds basic template for Marvell OcteonTX2's CGX ethernet interface driver. Just the probe. RVU AF driver will use APIs exported by this driver for various things like PF to physical interface mapping, loopback mode, interface stats etc. Hence marged both drivers into a single module.

2018-10-10octeontx2-af: Reconfig MSIX base with IOVAGeetha sowjanya2-3/+32
HW interprets RVU_AF_MSIXTR_BASE address as an IOVA, hence create a IOMMU mapping for the physcial address configured by firmware and reconfig RVU_AF_MSIXTR_BASE with IOVA.

2018-10-10octeontx2-af: Configure block LF's MSIX vector offsetSunil Goutham4-3/+357
Firmware configures a certain number of MSIX vectors to each of enabled RVU PF/VF. When a block LF is attached to a PF/VF, number of MSIX vectors needed by that LF are set aside (out of PF/VF's total MSIX vectors) and LF's msix_offset is configured in HW. Also added support for a RVU PF/VF to retrieve that block LF's MSIX vector offset information from AF via mbox. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2018-10-10octeontx2-af: Add RVU block LF provisioning supportSunil Goutham4-10/+523
Added support for a RVU PF/VF to request AF via mailbox to attach or detach NPA/NIX/SSO/SSOW/TIM/CPT block LFs. Also supports partial detachment and modifying current LF attached count of a certian block type. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S.

2018-10-10octeontx2-af: Scan blocks for LFs provisioned to PF/VFSunil Goutham3-2/+178
Scan all RVU blocks to find any 'LF to RVU PF/VF' mapping done by low level firmware. If found any, mark them as used in respective block's LF bitmap and also save mapped PF/VF's PF_FUNC info. This is done to avoid reattaching a block LF to a different RVU PF/VF. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-10-10octeontx2-af: Convert mbox msg id check to a macroAleksey Makarov1-6/+38
With 10's of mailbox messages expected to be handled in future, checking for message id could become a lengthy switch case. Hence added a macro to auto generate the switch case for each msg id.

2018-10-10octeontx2-af: Add mailbox IRQ and msg handlersSunil Goutham4-3/+309
This patch adds support for mailbox interrupt and message handling. Mapped mailbox region and registered a workqueue for message handling. Enabled mailbox IRQ of RVU PFs and registered a interrupt handler. When IRQ is triggered work is added to the mbox workqueue for msgs to get processed.
