2019-05-23cxgb4: use firmware API for validating filter specRaju Rangoju1-0/+1
Adds support for validating hardware filter spec configured in firmware before offloading exact match flows. Use the new fw api FW_PARAM_DEV_FILTER_MODE_MASK to read the filter mode and mask from firmware. If the api isn't supported, then fall-back to older way of reading just the mode from indirect register. Signed-off-by: Raju Rangoju <rajur@chelsio.com> Signed-off-by: David S.

2019-05-22cxgb4: Enable hash filter with offloadVishal Kulkarni1-0/+1
Hash (exact-match) filters used for offloading flows share the same active region resources on the chip with upper layer drivers, like iw_cxgb4, chcr, etc. Currently, only either Hash filters or ULDs can use the active region resources, but not both. Hence, use the new firmware configuration parameters (when available) to allow both the Hash filters and ULDs to share the active region simultaneously.

2019-02-14cxgb4/cxgb4vf: Add support for SGE doorbell queue timerVishal Kulkarni1-1/+9
T6 introduced a Timer Mechanism in SGE called the SGE Doorbell Queue Timer. With this we can now configure TX Queues to get CIDX Updates when: Time(CIDX == PIDX) >= Timer Previously we rely on TX Queue Status Page updates by hardware for DMA completions. This will make Hardware/Firmware actually deliver the CIDX Updates as Ingress Queue messages with commensurate Interrupts. So we now have a new RX Path component for processing CIDX Updates and reclaiming TX Descriptors faster.

{t4/t4_vf}_change_mac() API's were only doing additions to MPS_TCAM. This will fail, when the number of tcam entries is limited particularly in vf's. This fix programs hash region with the mac address, when TCAM addtion fails for {t4/t4vf}_change_mac(). Since the locally maintained driver list for hash entries is shared across mac_{sync/unsync}(), added an extra parameter if_mac to track the address added thorugh {t4/t4vf}_change_mac() Signed-off-by: Arjun Vynipadath <arjun@chelsio.com> Signed-off-by: David S.

2018-10-11cxgb4: fix thermal configuration dependenciesArnd Bergmann1-4/+2
With CONFIG_THERMAL=m, we get a build error: drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c: In function 'cxgb4_thermal_get_trip_type': drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.c:48:11: error: 'struct adapter' has no member named 'ch_thermal' Once that is fixed by using IS_ENABLED() checks, we get a link error against the thermal subsystem when cxgb4 is built-in: drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init': cxgb4_thermal.c:(.text+0x180): undefined reference to `thermal_zone_device_register' drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_remove': cxgb4_thermal.c:(.text+0x1e0): undefined reference to `thermal_zone_device_unregister' Finally, since CONFIG_THERMAL can be =m, the Makefile fails to pick up the extra file into built-in.a, and we get another link failure against the cxgb4_thermal_init/cxgb4_thermal_remove files, so the Makefile has to be adapted as well to work for both CONFIG_THERMAL=y and =m.

The present TX workrequest(FW_ETH_TX_PKT_WR) cant be used for host->vf communication, since it doesn't loopback the outgoing packets to virtual interfaces on the same port. This can be done using FW_ETH_TX_PKT_VM_WR. This fix depends on ethtool_flags to determine what WR to use for TX path. Support for setting this flags by user is added in next commit.

2018-06-22rhashtable: split rhashtable.hNeilBrown1-0/+1
Due to the use of rhashtables in net namespaces, rhashtable.h is included in lots of the kernel, so a small changes can required a large recompilation. This makes development painful. This patch splits out rhashtable-types.h which just includes the major type declarations, and does not include (non-trivial) inline code. rhashtable.h is no longer included by anything in the include/ directory. Common include files only include rhashtable-types.h so a large recompilation is only triggered when that changes.

2018-05-25cxgb4/cxgb4vf: Notify link changes to OS-dependent codeArjun Vynipadath1-0/+3
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.

2017-11-01cxgb4: convert flower table to use rhashtableKumar Sanghvi1-1/+3
T6 supports ~500K hash filters and can theoretically climb up to ~1 million hash filters. Preallocated hash table is not efficient in terms of memory usage. So, use rhashtable instead which gives the flexibility to grow based on usage.
