2018-10-23octeontx2-af: Install ucast and bcast pkt forwarding rulesSunil Goutham4-0/+375
Upon NIXLF_ALLOC install a unicast forwarding rule in NPC MCAM like below - Match pkt DMAC with NIXLF attached PF/VF's MAC address. - Ingress channel - Action is UCAST - Forward to PF_FUNC of this NIXLF And broadcast pkt forwarding rule as - Match L2B bit in MCAM search key - Ingress channel - Action is UCAST, for now, later it will be changed to MCAST. Only PFs can install this rule Upon NIXLF_FREE disable all MCAM entries in use by that NIXLF. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-10-23octeontx2-af: Add LMAC channel info to NIXLF_ALLOC responseStanislaw Kardach4-0/+18
Add LMAC channel info like Rx/Tx channel base and count to NIXLF_ALLOC mailbox message response. This info is used by NIXLF attached RVU PF/VF to configure SQ's default channel, TL3_TL2_LINKX_CFG and to install MCAM rules in NPC based on matching ingress channel number.

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: Enable packet length and csum validationSunil Goutham2-0/+28
Config NPC layer info from KPU profile into protocol checker to identify outer L2/IPv4/TCP/UDP headers in a packet. And enable IPv4 checksum validation. L3/L4 and L4 CSUM validation will be enabled by PF/VF drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox i.e 'nix_lf_alloc_req->rx_cfg' Also enable setting of NPC_RESULT_S[L2B] when an outer L2 broadcast address is detected. This will help in installing NPC MCAM rules for broadcast packets. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-10-23octeontx2-af: Broadcast packet replication supportSunil Goutham2-0/+220
Allocate memory for mcast/bcast/mirror replication entry contexts, replication buffers (used by HW) and config HW with corresponding memory bases. Added support for installing MCEs via NIX AQ mbox. For now support is restricted to broadcast pkt replication, hence MCE table size and number of replication buffers allocated are less. Each CGX LMAC mapped RVU PF is assigned a MCE table of size 'num VFs of that PF + PF'. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This patch configures all 16 KPUs and iKPU (pkinds) with the KPU parser profile defined in npc_profile.h. Each KPU engine has a 128 entry CAM, only CAM entries which are listed in the profile are enabled and rest are left disabled. Also - Memory is allocated for pkind's bitmap and PFFUNC, interface channel mapping. - Added all CSR offsets of NPC HW block.

2018-10-23octeontx2-af: Add NPC KPU profileHao Zheng2-0/+5852
NPC block is responsible for parsing and forwarding packets to different NIXLFs. NPC has 16 KPU engines (Kangaroo parse engine) and one iKPU which represents pkinds. Each physical port either CGX/LBK is assigned a pkind and upon receiving a packet HW takes that port's pkind and starts parsing as per the KPU engines config. This patch adds header files which contain configuration profile/array for each of the iKPU and 16 KPU engines.

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.

2018-10-23octeontx2-af: NIX Tx scheduler queues alloc/freeSunil Goutham4-4/+265
Added support for a PF/VF to allocate or free NIX transmit scheduler queues via mbox. 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. Upon receiving NIX_TXSCH_FREE mbox msg all scheduler queues allocated to sending PFFUNC (PF/VF) will be freed. Selective free is not supported.

2018-10-20netpoll: allow cleanup to be synchronousDebabrata Banerjee3-6/+4
This fixes a problem introduced by: commit 2cde6acd49da ("netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lock") When using netconsole on a bond, __netpoll_cleanup can asynchronously recurse multiple times, each __netpoll_free_async call can result in more __netpoll_free_async's. This means there is now a race between cleanup_work queues on multiple netpoll_info's on multiple devices and the configuration of a new netpoll. For example if a netconsole is set to enable 0, reconfigured, and enable 1 immediately, this netconsole will likely not work. Given the reason for __netpoll_free_async is it can be called when rtnl is not locked, if it is locked, we should be able to execute synchronously. It appears to be locked everywhere it's called from. Generalize the design pattern from the teaming driver for current callers of __netpoll_free_async.
