thermal/drivers/cxgb4: Use generic thermal_zone_get_trip() function The thermal framework gives the possibility to register the trip points with the thermal zone. When that is done, no get_trip_* ops are needed and they can be removed. Convert ops content logic into generic trip points and register them with the thermal zone.

cxgb4/ch_ktls: creating skbs causes panic Creating SKB per tls record and freeing the original one causes panic. There will be race if connection reset is requested. By freeing original skb, refcnt will be decremented and that means, there is no pending record to send, and so tls_dev_del will be requested in control path while SKB of related connection is in queue. Better approach is to use same SKB to send one record (partial data) at a time. We still have to create a new SKB when partial last part of a record is requested. This fix introduces new API cxgb4_write_partial_sgl() to send partial part of skb. Present cxgb4_write_sgl can only provide feasibility to start from an offset which limits to header only and it can write sgls for the whole skb len. But this new API will help in both. It can start from any offset and can end writing in middle of the skb. v4->v5: - Removed extra changes.

The packet goes until the Multi Port Switch (MPS) just before the MAC and based on the specified channel number, it either goes outside the wire on one of the physical ports or looped back to Rx path by MPS. In this case, we're specifying loopback channel, instead of physical ports, so the packet gets looped back to Rx path, instead of getting transmitted on the wire. v3: - Modify commit message to include test details. v2: - Add only loopback self-test.

cxgb4/chcr: update SGL DMA unmap for USO The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO) requests expects the headers to be part of the descriptor and the payload to be part of the SGL containing the DMA mapped addresses. Hence, the DMA address in the first entry of the SGL can start after the packet headers. Currently, unmap_sgl() tries to unmap from this wrong offset, instead of the originally mapped DMA address. So, use existing unmap_skb() instead, which takes originally saved DMA addresses as input. Update all necessary Tx paths to save the original DMA addresses, so that unmap_skb() can unmap them properly. v2: - No change.

cxgb4: check rule prio conflicts before offload Only offload rule if it satisfies both of the following conditions: 1. The immediate previous rule has priority <= current rule's priority. 2. The immediate next rule has priority >= current rule's priority. Also rework free entry fetch logic to search from end of TCAM, instead of beginning, because higher indices have lower priority than lower indices. This is similar to how TC auto generates priority values. v5: - Fixed commit message and comment to include comparison for equal priority. v4: - Patch added in this version.

cxgb4: add TC-MATCHALL classifier egress offload Add TC-MATCHALL classifier offload with TC-POLICE action applied for all outgoing traffic on the underlying interface. Split flow block offload to support both egress and ingress classification. For example, to rate limit all outgoing traffic to 1 Gbps: $ tc qdisc add dev enp2s0f4 clsact $ tc filter add dev enp2s0f4 egress matchall skip_sw \ action police rate 1Gbit burst 8Kbit Note that skip_sw is important. Otherwise, both stack and hardware will end up doing policing. Policing can't be shared across flow blocks. Only 1 egress matchall rule can be active at a time on the underlying interface. v5: - No change. v4: - Removed check to reject police offload if prio is not 1. - Moved TC_SETUP_BLOCK code to separate function. v3: - Added check to reject police offload if prio is not 1. - Assign block_shared variable only for TC_SETUP_BLOCK. v2: - Added check to reject flow block sharing for policers.

cxgb4: add FLOWC based QoS offload Rework SCHED API to allow offloading TC-MQPRIO QoS configuration. The existing QUEUE based rate limiting throttles all queues sharing a traffic class, to the specified max rate limit value. So, if multiple queues share a traffic class, then all the queues get the aggregate specified max rate limit. So, introduce the new FLOWC based rate limiting, where multiple queues can share a traffic class with each queue getting its own individual specified max rate limit. For example, if 2 queues are bound to class 0, which is rate limited to 1 Gbps, then 2 queues using QUEUE based rate limiting, get the aggregate output of 1 Gbps only. In FLOWC based rate limiting, each queue gets its own output of max 1 Gbps each; i.e. 2 queues * 1 Gbps rate limit = 2 Gbps.

cxgb4/cxgb4vf: Notify link changes to OS-dependent code We have a confusion of two different abstractions in the Common Code: Physical Link (Port) and Logical Network Interface (Virtual Interface), and we haven't been properly managing the state of the intersection of those two abstractions. On the one hand we have the Physical state of the Link -- up or down -- and on the other we have the logical state of the VI, enabled or not. {ethN} refers to both the Physical and Logical State. In this case, ifconfig only affects/interrogates the Logical State of a VI, and ethtool only deals with the Physical State. And these are different. So, just because we disable the VI, we don't really want to change the Physical Link Up/Down state. Thus, the previous hack to set "lc->link_ok = 0" when we disable a VI is completely incorrect. Where we get into trouble is where the Physical Link State and the Logical VI State cross swords. And that happens in t4_handle_get_port_info() where we need to manage/safe the Physical Link State, but we also need to know when the Logical VI State has changed and pass that back up to the OS-dependent Driver routine t4_os_link_changed() which is concerned about the Logical Interface. So we enable a VI and that causes Firmware to send us a new Port Information message, but if none of the Physical Link State particulars have changed, we don't call t4_os_link_changed(). This fix uses the existing OS Contract APIs for the Common Code to inform the OS-dependent portion of the Host Driver when the "Link" (really Logical Network Interface) is "up" or "down". A new API t4_enable_pi_params() is added which calls t4_enable_vi_params() and, if that is successful, then calls back to the OS Contract API t4_os_link_changed() notifying the OS-dependent layer of the potential Link State change.

Allocate SMT/L2T entries if DMAC-rewrite/SMAC-rewrite is requested. Allocate CLIP entry in case of IPv6 filter. Use cpl_act_open_req[6] to send hash filter create request to hw. Also, the filter tuple is calculated as part of sending this request. Hash-filter reply is processed on getting cpl_act_open_rpl. In case of success, various bits/fields in filter-tcb are set per filter requirement, such as enabling filter hitcnts, and/or various header rewrite operations, such as VLAN-rewrite, NAT or (L3/L4)-rewrite, and SMAC/DMAC-rewrite. In case of failure, clear the filter entry and release any hw resources occupied by it.

treewide: use kv[mz]alloc* rather than opencoded variants There are many code paths opencoding kvmalloc. Let's use the helper instead. The main difference to kvmalloc is that those users are usually not considering all the aspects of the memory allocator. E.g. allocation requests <= 32kB (with 4kB pages) are basically never failing and invoke OOM killer to satisfy the allocation. This sounds too disruptive for something that has a reasonable fallback - the vmalloc. On the other hand those requests might fallback to vmalloc even when the memory allocator would succeed after several more reclaim/compaction attempts previously. There is no guarantee something like that happens though. This patch converts many of those places to kv[mz]alloc* helpers because they are more conservative.

cxgb4: Shutdown adapter if firmware times out or errors out Perform an emergency shutdown of the adapter and stop it from continuing any further communication on the ports or DMA to the host. This is typically used when the adapter and/or firmware have crashed and we want to prevent any further accidental communication with the rest of the world. This will also force the port Link Status to go down -- if register writes work -- which should help our peers figure out that we're down.

cxgb4: Synchronize access to mailbox The issue comes when there are multiple threads attempting to use the mailbox facility at the same time. When DCB operations and interface up/down is run in a loop for every 0.1 sec, we observed mailbox collisions. And out of the two commands one would fail with the present code, since we don't queue the second command. To overcome the above issue, added a queue to access the mailbox. Whenever a mailbox command is issued add it to the queue. If its at the head issue the mailbox command, else wait for the existing command to complete. Usually command takes less than a milli-second to complete. Also timeout from the loop, if the command under execution takes long time to run. In reality, the number of mailbox access collisions is going to be very rare since no one runs such abusive script. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S.

One such case involved the Firmware sending a "Flush Token" through the ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to make sure there weren't any remaining TX Work Requests in the pipeline. But the return path was stalled by Ingress Data unable to be delivered to the Host because those Ingress Queues were no longer being serviced.

cxgb4: Rename t4_link_start() to t4_link_l1cfg t4_link_start() was completely misnamed. It does _not_ start up the link. It merely does the L1 Configuration for the link. The Link Up process is started automatically by the firmware when the number of enabled Virtual Interfaces on a port goes from 0 to 1. So renaming this routine to t4_link_l1cfg() for better documentation. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

cxgb4/cxgb4vf: function and argument name cleanup This patch changes variable name 'fn' to 'pf' of structure adapter. A 'fn' usually stands for PCI function which could be a PF or a VF. However, the use of this particular variable is explicitly limited to PF only. So, be specific about it in the variable name. Also corrects arguments passed for fn t4_ofld_eq_free, t4_ctrl_eq_free, t4_eth_eq_free, t4_iq_free, t4_alloc_vi, t4_fw_hello, t4_wr_mbox and t4_cfg_pfvf function. Also renames cxgb4_t4_bar2_sge_qregs to t4_bar2_sge_qregs and renames the latter function name in cxgb4vf driver to t4vf_bar2_sge_qregs to avoid conflicts. Also fixes alignment for these function.

cxgb4: Allocate dynamic mem. for egress and ingress queue maps QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END. For eg, in the first load eqid can be from 100 to 300. In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is 1000). The driver was assuming them to always start from EQ(IQFLINT)_START till MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash. Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for these structures.

cxgb4/iw_cxgb4: use firmware ord/ird resource limits Advertise a larger max read queue depth for qps, and gather the resource limits from fw and use them to avoid exhaustinq all the resources. Design: cxgb4: Obtain the max_ordird_qp and max_ird_adapter device params from FW at init time and pass them up to the ULDs when they attach. If these parameters are not available, due to older firmware, then hard-code the values based on the known values for older firmware. iw_cxgb4: Fix the c4iw_query_device() to report these correct values based on adapter parameters. ibv_query_device() will always return: max_qp_rd_atom = max_qp_init_rd_atom = min(module_max, max_ordird_qp) max_res_rd_atom = max_ird_adapter Bump up the per qp max module option to 32, allowing it to be increased by the user up to the device max of max_ordird_qp. 32 seems to be sufficient to maximize throughput for streaming read benchmarks. Fail connection setup if the negotiated IRD exhausts the available adapter ird resources. So the driver will track the amount of ird resource in use and not send an RI_WR/INIT to FW that would reduce the available ird resources below zero.

Set up PCI-E Memory Window registers using the true values programmed into BAR registers. When the PF4 "Master Function" is exported to a Virtual Machine, the values returned by pci_resource_start() will be for the synthetic PCI-E Configuration Space and not the real addresses.

iw_cxgb4: Allocate and use IQs specifically for indirect interrupts Currently indirect interrupts for RDMA CQs funnel through the LLD's RDMA RXQs, which also handle direct interrupts for offload CPLs during RDMA connection setup/teardown. The intended T4 usage model, however, is to have indirect interrupts flow through dedicated IQs. IE not to mix indirect interrupts with CPL messages in an IQ. This patch adds the concept of RDMA concentrator IQs, or CIQs, setup and maintained by the LLD and exported to iw_cxgb4 for use when creating CQs. RDMA CPLs will flow through the LLD's RDMA RXQs, and CQ interrupts flow through the CIQs. Design: cxgb4 creates and exports an array of CIQs for the RDMA ULD. These IQs are sized according to the max available CQs available at adapter init. In addition, these IQs don't need FL buffers since they only service indirect interrupts. One CIQ is setup per RX channel similar to the RDMA RXQs. iw_cxgb4 will utilize these CIQs based on the vector value passed into create_cq(). The num_comp_vectors advertised by iw_cxgb4 will be the number of CIQs configured, and thus the vector value will be the index into the array of CIQs.

cxgb4/iw_cxgb4: Doorbell Drop Avoidance Bug Fixes The current logic suffers from a slow response time to disable user DB usage, and also fails to avoid DB FIFO drops under heavy load. This commit fixes these deficiencies and makes the avoidance logic more optimal. This is done by more efficiently notifying the ULDs of potential DB problems, and implements a smoother flow control algorithm in iw_cxgb4, which is the ULD that puts the most load on the DB fifo. Design: cxgb4: Direct ULD callback from the DB FULL/DROP interrupt handler. This allows the ULD to stop doing user DB writes as quickly as possible. While user DB usage is disabled, the LLD will accumulate DB write events for its queues. Then once DB usage is reenabled, a single DB write is done for each queue with its accumulated write count. This reduces the load put on the DB fifo when reenabling. iw_cxgb4: Instead of marking each qp to indicate DB writes are disabled, we create a device-global status page that each user process maps. This allows iw_cxgb4 to only set this single bit to disable all DB writes for all user QPs vs traversing the idr of all the active QPs. If the libcxgb4 doesn't support this, then we fall back to the old approach of marking each QP. Thus we allow the new driver to work with an older libcxgb4. When the LLD upcalls iw_cxgb4 indicating DB FULL, we disable all DB writes via the status page and transition the DB state to STOPPED. As user processes see that DB writes are disabled, they call into iw_cxgb4 to submit their DB write events. Since the DB state is in STOPPED, the QP trying to write gets enqueued on a new DB "flow control" list. As subsequent DB writes are submitted for this flow controlled QP, the amount of writes are accumulated for each QP on the flow control list. So all the user QPs that are actively ringing the DB get put on this list and the number of writes they request are accumulated. When the LLD upcalls iw_cxgb4 indicating DB EMPTY, which is in a workq context, we change the DB state to FLOW_CONTROL, and begin resuming all the QPs that are on the flow control list. This logic runs on until the flow control list is empty or we exit FLOW_CONTROL mode (due to a DB DROP upcall, for example). QPs are removed from this list, and their accumulated DB write counts written to the DB FIFO. Sets of QPs, called chunks in the code, are removed at one time. The chunk size is 64. So 64 QPs are resumed at a time, and before the next chunk is resumed, the logic waits (blocks) for the DB FIFO to drain. This prevents resuming to quickly and overflowing the FIFO. Once the flow control list is empty, the db state transitions back to NORMAL and user QPs are again allowed to write directly to the user DB register. The algorithm is designed such that if the DB write load is high enough, then all the DB writes get submitted by the kernel using this flow controlled approach to avoid DB drops. As the load lightens though, we resume to normal DB writes directly by user applications. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: David S. Miller <davem@davemloft.net>

cxgb4: Add support for T4 configuration file Starting with T4 firmware version 1.3.11.0 the firmware now supports device configuration via a Firmware Configuration File. The Firmware Configuration File was primarily developed in order to centralize all of the configuration, resource allocation, etc. for Unified Wire operation where multiple Physical / Virtual Function Drivers would be using a T4 adapter simultaneously. The Firmware Configuration file can live in three locations as shown below in order of precedence. 1) User defined configuration file: /lib/firmware/cxgb4/t4-config.txt 2) Factory Default configuration file written to FLASH within the manufacturing process. 3) Hardwired driver configuration.

cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File support This patch adds new enums and macros to enable T4 configuration file support. It also removes duplicate macro definitions. It fixes the build failure in cxgb4vf driver introduced because of old macro definition removal. It also performs SGE initialization based on T4 configuration file is provided or not. If it is provided then it uses the parameters provided in it otherwise it uses hard coded values.

cxgb4: Add functions to read memory via PCIE memory window This patch implements two new functions t4_mem_win_read and t4_memory_read. These new functions can be used to read memory via the PCIE memory window. Please note, for proper execution of these functions PCIE_MEM_ACCESS_BASE_WIN registers must be setup correctly like how setup_memwin in the cxgb4 driver does it.

cxgb4: DB Drop Recovery for RDMA and LLD queues recover LLD EQs for DB drop interrupts. This includes adding a new db_lock, a spin lock disabling BH too, used by the recovery thread and the ring_tx_db() paths to allow db drop recovery. Clean up initial DB avoidance code. Add read_eq_indices() - this allows the LLD to use the PCIe mw to efficiently read hw eq contexts. Add cxgb4_sync_txq_pidx() - called by iw_cxgb4 to sync up the sw/hw pidx value. Add flush_eq_cache() and cxgb4_flush_eq_cache(). This allows iw_cxgb4 to flush the sge eq context cache before beginning db drop recovery. Add module parameter, dbfoifo_int_thresh, to allow tuning the db interrupt threshold value. Add dbfifo_int_thresh to cxgb4_lld_info so iw_cxgb4 knows the threshold. Add module parameter, dbfoifo_drain_delay, to allow tuning the amount of time delay between DB FULL and EMPTY upcalls to iw_cxgb4.

cxgb4: Common platform specific changes for DB Drop Recovery Add platform-specific callback functions for interrupts. This is needed to do a single read-clear of the CAUSE register and then call out to platform specific functions for DB threshold interrupts and DB drop interrupts. Add t4_mem_win_read_len() - mem-window reads for arbitrary lengths. This is used to read the CIDX/PIDX values from EC contexts during DB drop recovery. Add t4_fwaddrspace_write() - sends addrspace write cmds to the fw. Needed to flush the sge eq context cache.
