Fri, 23 Jul 2021 22:31:32 +0000

Upgrade ENA to v2.4.1ena: Remove redundant declaration of ena_log_level.GCC6 raises a -Wredundant-decl error due to duplicate declarationsin ena_fbsd_log.h and ena_plat.h.Sponsored by: Chelsio Communications(cherry picked from commit 8843787aa1bdbd10de6ba47a04489179ec2d2d3c)ena: Avoid unnecessary mbuf collapses for LLQ conditionIn case of Low-latency Queue, one small enough descriptor can be pusheddirectly to the ENA hw, thus saving one fragment. Check for thiscondition before performing collapse.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit c81f8c26115a64b9a97ecdb2a64e824dd839ee73)ena: Trigger reset on ena_com_prepare_tx failureAll ena_com_prepare_tx errors other than ENA_COM_NO_MEM are fatal andrequire device reset.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 36130d2979d695dd439bc607feb00dcdb9a1937b)ena: Prevent reset after device destructionCheck for ENA_FLAG_TRIGGER_RESET inside a locked context in order toavoid potential race conditions with ena_destroy_device. This aligns thereset task logic with the Linux driver.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 433ab9b6987b42b3e5b25b8b5dc7e5178c7ef9bb)ena: Add extra log messagesStay aligned with the Linux driver by adding the following logs:* inform the user about retrying queue creation* warn on non-empty ena_tx_buffer.mbuf prior to ena_tx_map_mbufObtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 77160654a162b5faa8ad7a02e18d2bef2589f868)ena: Add locking assertionsENA silently assumed that ena_up, ena_down and ena_start_xmit routinesshould be called within locked context. Driver's logic heavily assumeson concurrent access to those routines, so for safety and betterdocumentation about this assumption, the locking assertions were addedto the above functions.The assertion was added only for the main steps (skipping the helperfunctions) which can be called from multiple places including the kerneland the driver itself.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit cb98c439d66c303353a9f4abbbe9ddb51559c638)ena: Move RSS logic into its own source filesDelegate RSS related functionality into separate .c/.h files inpreparation for the full RSS support.While at it, reorder functions and remove prototypes for ones withinternal linkage.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 986e7b9227668caf9620f207e3c1d708c87b634d)ena: Disable meta descriptor caching for netmapIf LLQ is being used, `ena_tx_ctx.meta_valid` must stay enabled. Thisfixes netmap support on latest generation ENA HW and aligns it with thecore driver behavior.As netmap doesn't support any csum offloads, the`adapter->disable_meta_caching` value can be simply passed to the HW.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit a831466830de6ab55fc03170290b313157196e81)ena: Share ena_global_lock between driver instancesIn order to use `ena_global_lock` in sysctl context, it must be keptoutside the driver instance's software context, as sysctls can be calledbefore attach and after detach, leading to lock use before sx_init andafter sx_destroy otherwise.Solve this issue by turning `ena_global_lock` into a file scopevariable, shared between all instances of the driver and associatedsysctl context, and in turn initialized/destroyed in dedicatedSYSINIT/SYSUNINIT functions.As a side effect, this change also fixes existing race in the resetroutine, when simultaneously accessing sysctl exposed properties.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 07aff471c0de2de9a1dc5c7749c46b525bdd0201)ena: Add missing statisticsProvide the following sysctl statistics in order to stay aligned withthe Linux driver:* rx_ring.csum_good* tx_ring.unmask_interrupt_numAlso rename the 'bad_csum' statistic name to 'csum_bad' for alignment.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 223c8cb12e951c63807300a0cbdc4a1569520b4b)ena: Implement full RSS reconfigurationBind RX/TX queues and MSI-X vectors to matching CPUs based on the RSSbucket entries.Introduce sysctls for the following RSS functionality:- rss.indir_table: indirection table mapping- rss.indir_table_size: indirection table size- rss.key: RSS hash key (if Toeplitz used)Said sysctls are only available when compiled without `option RSS`, askernel-side RSS support currently doesn't offer RSS reconfiguration.Migrate the hash algorithm from CRC32 to Toeplitz and change the initialhash value to 0x0 in order to match the standard Toeplitz implementation.Provide helpers for hash key inversion required for HW operations.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 6d1ef2abd330fac4057f092abbbdc28a568b4327)ena: fix building in-kernel driverWhen building ENA as compiled into the kernel, the driver would fail tobuild. Resolve the problem by introducing the following changes:1. Add missing `ena_rss.c` entry in `sys/conf/files`.2. Prevent SYSCTL_ADD_INT from throwing an assert due to an extraCTLTYPE_INT flag.Fixes: 986e7b92276 ("ena: Move RSS logic into its own source files")Fixes: 6d1ef2abd33 ("ena: Implement full RSS reconfiguration")Obtained from: SemihalfSponsored by: Amazon, Inc.MFC after: 1 week(cherry picked from commit a3f0d18237bdcf272461d3b4b682de384c572144)ena: Update driver version to v2.4.1Some of the changes in this release:* Hardware RSS hash key reconfiguration and indirection tablereconfiguration support.* Full kernel RSS support.* Extra statistic counters.* Netmap support for ENAv3.* Locking assertions.* Extra log messages.* Reset handling fixes.Obtained from: SemihalfMFC after: 2 weeksSponsored by: Amazon, Inc.(cherry picked from commit 42c7760be3ea420668f625f2064ae347aa7e818e) List of files: /freebsd-13.1/sys/modules/ena/Makefile

0835cc78 - Add SPDX license tag to the ENA driver files

Wed, 18 Nov 2020 15:07:34 +0000

Add SPDX license tag to the ENA driver filesRefering to guide: https://wiki.freebsd.org/SPDX the SPDX tag should notreplace the standard license text, however it should be added over thestandard license text to make the automation easier.Because of that, the old license was kept, but the SPDX tag was addedon top of every ENA driver file.Submited by: Michal Krawczyk Obtained from: SemihalfSponsored by: Amazon, IncMFC after: 1 weekDifferential revision: https://reviews.freebsd.org/D27117 List of files: /freebsd-13.1/sys/modules/ena/Makefile

d17b7d87 - Introduce NETMAP support in ENA

Thu, 31 Oct 2019 15:51:18 +0000

Introduce NETMAP support in ENAMock implementation of NETMAP routines is located in ena_netmap.c/.hfiles. All code is protected under the DEV_NETMAP macro. Makefile wasupdated with files and flag.As ENA driver provide own implementations of (un)likely it must beundefined before including NETMAP headers.ena_netmap_attach function is called on the end of NIC attach. It fillsstructure with NIC configuration and callbacks. Then provides it tonetmap_attach. Similarly netmap_detach is called during ena_detach.Three callbacks are used.nm_register is implemented by ena_netmap_reg. It is called when userspace application open or close NIC in NETMAP mode. Current action isrecognized based on onoff parameter: true means on and false off. AsNICs rings need to be reconfigured ena_down and ena_up are reused.When user space application wants to receive new packets from NICnm_rxsync is called, and when there are new packets ready for Txnm_txsync is called.Differential Revision: https://reviews.freebsd.org/D21934Submitted by: Rafal Kozik Michal Krawczyk Obtained from: SemihalfSponsored by: Amazon, Inc.

9b8d05b8 - Add support for Amazon Elastic Network Adapter (ENA) NIC

Mon, 22 May 2017 14:46:13 +0000

Add support for Amazon Elastic Network Adapter (ENA) NICENA is a networking interface designed to make good use of modern CPUfeatures and system architectures.The ENA device exposes a lightweight management interface with aminimal set of memory mapped registers and extendable command setthrough an Admin Queue.The driver supports a range of ENA devices, is link-speed independent(i.e., the same driver is used for 10GbE, 25GbE, 40GbE, etc.), and hasa negotiated and extendable feature set.Some ENA devices support SR-IOV. This driver is used for both theSR-IOV Physical Function (PF) and Virtual Function (VF) devices.ENA devices enable high speed and low overhead network trafficprocessing by providing multiple Tx/Rx queue pairs (the maximum numberis advertised by the device via the Admin Queue), a dedicated MSI-Xinterrupt vector per Tx/Rx queue pair, and CPU cacheline optimizeddata placement.The ENA driver supports industry standard TCP/IP offload features suchas checksum offload and TCP transmit segmentation offload (TSO).Receive-side scaling (RSS) is supported for multi-core scaling.The ENA driver and its corresponding devices implement healthmonitoring mechanisms such as watchdog, enabling the device and driverto recover in a manner transparent to the application, as well asdebug logs.Some of the ENA devices support a working mode called Low-latencyQueue (LLQ), which saves several more microseconds. This feature willbe implemented for driver in future releases.Submitted by: Michal Krawczyk Jakub Palider Jan Medala Obtained from: SemihalfSponsored by: Amazon.com Inc.Differential revision: https://reviews.freebsd.org/D10427 List of files: /freebsd-13.1/sys/modules/ena/Makefile
