e5f31552674e88bff3a4e3ca3e5357668b5f2973 - ethernet: fix PTP_1588_CLOCK dependencies

Thu, 12 Aug 2021 20:33:58 +0200

ethernet: fix PTP_1588_CLOCK dependenciesThe 'imply' keyword does not do what most people think it does, it onlypolitely asks Kconfig to turn on another symbol, but does not preventit from being disabled manually or built as a loadable module when theuser is built-in. In the ICE driver, the latter now causes a link failure:aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl':ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config'ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config'aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config'ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config'aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset':ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release'ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release'aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild':This is a recurring problem in many drivers, and we have discussedit several times befores, without reaching a consensus. I'm providinga link to the previous email thread for reference, which discussessome related problems.To solve the dependency issue better than the 'imply' keyword, introduce aseparate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any drivercan depend on if it is able to use PTP support when available, but worksfine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers arethen prevented from being built-in, the same way as with a 'depends onPTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick,but that can be rather confusing when you first see it.Since this should cover the dependencies correctly, the IS_REACHABLE()hack in the header is no longer needed now, and can be turned backinto a normal IS_ENABLED() check. Any driver that gets the dependencywrong will now cause a link time failure rather than being unable to usePTP support when that is in a loadable module.However, the two recently added ptp_get_vclocks_index() andptp_convert_timestamp() interfaces are only called from builtin code withethtool and socket timestamps, so keep the current behavior by stubbingthose out completely when PTP is in a loadable module. This should beaddressed properly in a follow-up.As Richard suggested, we may want to actually turn PTP support into a'bool' option later on, preventing it from being a loadable modulealtogether, which would be one way to solve the problem with the ethtoolinterface.Fixes: 06c16d89d2cb ("ice: register 1588 PTP clock device object for E810 devices")Link: https://lore.kernel.org/netdev/20210804121318.337276-1-arnd@kernel.org/Link: https://lore.kernel.org/netdev/CAK8P3a06enZOf=XyZ+zcAwBczv41UuCTz+=0FMf2gBz1_cOnZQ@mail.gmail.com/Link: https://lore.kernel.org/netdev/CAK8P3a3=eOxE-K25754+fB_-i_0BZzf9a9RfPTX3ppSwu9WZXw@mail.gmail.com/Link: https://lore.kernel.org/netdev/20210726084540.3282344-1-arnd@kernel.org/Acked-by: Shannon Nelson Acked-by: Jacob Keller Acked-by: Richard Cochran Reviewed-by: Vladimir Oltean Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20210812183509.1362782-1-arnd@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/ethernet/qlogic/Kconfig

eda1bc65b0dc1b03006e427430ba23746ec44714 - Merge branch 'QED-NVMeTCP-Offload'

Thu, 03 Jun 2021 23:04:18 +0200

Merge branch 'QED-NVMeTCP-Offload'Shai Malin says:====================QED NVMeTCP OffloadIntro:======This is the qed part of Marvell’s NVMeTCP offload series, shared asRFC series "NVMeTCP Offload ULP and QEDN Device Drive".This part is a standalone series, and is not dependent on other partsof the RFC.The overall goal is to add qedn as the offload driver for NVMeTCP,alongside the existing offload drivers (qedr, qedi and qedf for rdma,iscsi and fcoe respectively).In this series we are making the necessary changes to qed to enable thisby exposing APIs for FW/HW initializations.The qedn series (and required changes to NVMe stack) will be sent to thelinux-nvme mailing list.I have included more details on the upstream plan under section with thesame name below.The Series Patches:===================1. qed: Add TCP_ULP FW resource layout – replacing iSCSI when common with NVMeTCP.2. qed: Add NVMeTCP Offload PF Level FW and HW HSI.3. qed: Add NVMeTCP Offload Connection Level FW and HW HSI.4. qed: Add support of HW filter block – enables redirecting NVMeTCP traffic to the dedicated PF.5. qed: Add NVMeTCP Offload IO Level FW and HW HSI.6. qed: Add NVMeTCP Offload IO Level FW Initializations.7. qed: Add IP services APIs support –VLAN, IP routing and reserving TCP ports for the offload device.The NVMeTCP Offload:====================With the goal of enabling a generic infrastructure that allows NVMe/TCPoffload devices like NICs to seamlessly plug into the NVMe-oF stack, thispatch series introduces the nvme-tcp-offload ULP host layer, which willbe a new transport type called "tcp-offload" and will serve as anabstraction layer to work with vendor specific nvme-tcp offload drivers.NVMeTCP offload is a full offload of the NVMeTCP protocol, this includesboth the TCP level and the NVMeTCP level.The nvme-tcp-offload transport can co-exist with the existing tcp andother transports. The tcp offload was designed so that stack changes arekept to a bare minimum: only registering new transports.All other APIs, ops etc. are identical to the regular tcp transport.Representing the TCP offload as a new transport allows clear and manageabledifferentiation between the connections which should use the offload pathand those that are not offloaded (even on the same device).The nvme-tcp-offload layers and API compared to nvme-tcp and nvme-rdma:* NVMe layer: * [ nvme/nvme-fabrics/blk-mq ] | (nvme API and blk-mq API) | |* Vendor agnostic transport layer: * [ nvme-rdma ] [ nvme-tcp ] [ nvme-tcp-offload ] | | | (Verbs) | | | | (Socket) | | | | | (nvme-tcp-offload API) | | | | | |* Vendor Specific Driver: * | | | [ qedr ] | | [ qede ] | [ qedn ]Performance:============With this implementation on top of the Marvell qedn driver (using theMarvell FastLinQ NIC), we were able to demonstrate the following CPUutilization improvement:On AMD EPYC 7402, 2.80GHz, 28 cores:- For 16K queued read IOs, 16jobs, 4qd (50Gbps line rate): Improved the CPU utilization from 15.1% with NVMeTCP SW to 4.7% with NVMeTCP offload.On Intel(R) Xeon(R) Gold 5122 CPU, 3.60GHz, 16 cores:- For 512K queued read IOs, 16jobs, 4qd (25Gbps line rate): Improved the CPU utilization from 16.3% with NVMeTCP SW to 1.1% with NVMeTCP offload.In addition, we were able to demonstrate the following latency improvement:- For 200K read IOPS (16 jobs, 16 qd, with fio rate limiter): Improved the average latency from 105 usec with NVMeTCP SW to 39 usec with NVMeTCP offload. Improved the 99.99 tail latency from 570 usec with NVMeTCP SW to 91 usec with NVMeTCP offload.The end-to-end offload latency was measured from fio while running againstback end of null device.The Marvell FastLinQ NIC HW engine:====================================The Marvell NIC HW engine is capable of offloading the entire TCP/IPstack and managing up to 64K connections per PF, already implemented andupstream use cases for this include iWARP (by the Marvell qedr driver)and iSCSI (by the Marvell qedi driver).In addition, the Marvell NIC HW engine offloads the NVMeTCP queue layerand is able to manage the IO level also in case of TCP re-transmissionsand OOO events.The HW engine enables direct data placement (including the data digest CRCcalculation and validation) and direct data transmission (including datadigest CRC calculation).The Marvell qedn driver:========================The new driver will be added under "drivers/nvme/hw" and will be enabledby the Kconfig "Marvell NVM Express over Fabrics TCP offload".As part of the qedn init, the driver will register as a pci device driverand will work with the Marvell fastlinQ NIC.As part of the probe, the driver will register to the nvme_tcp_offload(ULP) and to the qed module (qed_nvmetcp_ops) - similar to other"qed_*_ops" which are used by the qede, qedr, qedf and qedi devicedrivers.Upstream Plan:=============The RFC series "NVMeTCP Offload ULP and QEDN Device Driver"https://lore.kernel.org/netdev/20210531225222.16992-1-smalin@marvell.com/was designed in a modular way so that part 1 (nvme-tcp-offload) andpart 2 (qed) are independent and part 3 (qedn) depends on both parts 1+2.- Part 1 (RFC patch 1-8): NVMeTCP Offload ULP The nvme-tcp-offload patches, will be sent to 'linux-nvme@lists.infradead.org'.- Part 2 (RFC patches 9-15): QED NVMeTCP Offload The qed infrastructure, will be sent to 'netdev@vger.kernel.org'.Once part 1 and 2 are accepted:- Part 3 (RFC patches 16-27): QEDN NVMeTCP Offload The qedn patches, will be sent to 'linux-nvme@lists.infradead.org'.====================Signed-off-by: David S.
