This commit introduces a number of infrastructures in ena-com, some of which are being used as of ENA v2.7.0 while other certain infrastructure assets have been made available for potential future application. Upgrade ena-com to include the following changes: * Introduce customer metrics infrastructures * Introduce SRD metrics infrastructures * Remove unused fields from ena_com_io_cq and ena_com_io_sq structs * Minor rework of ena_com_fill_hash_function * Introduce PHC infrastructures * Update the licenses for ena-com files * Delete duplicate *_defs.h found in ena-com and ena_defs directories * Add validation for completion descriptors consistency * Move ena_fbsd_log.h file to ena_plat.h Approved by: cperciva (mentor) Sponsored by: Amazon, Inc.

ena-com: add NUMA allocations macros

2022-01-21T18:57:04Z

Add implementation for the ENA_MEM_ALLOC_NODE and ENA_MEM_ALLOC_COHERENT_NODE_* macros. Also the signature of ena_dma_alloc() function was updated, for which the implementation will be updated in ENA driver's patch.

ena-com: remove CSUM_OFFLOAD from the plat file

2022-01-21T18:57:04Z

CSUM_OFFLOAD is a constant which is used only by the core driver code. Because of that it shouldn't be defined in the platform file, as it's not the platform specific code which is used only by the ena_com layer.

ena-com: restructure the ENA logging system

2021-06-24T13:48:26Z

Introduce a new logging system, which replaces the old logging method. All logs are now displayed in `device_printf` format, requiring `adapter->pdev` to be passed down to `ena_log`. Whenever that's impossible, a `printf` wrapped `ena_log_raw` is provided. For netmap logs, `ena_log_nm` is available, prepending "[nm] " to an `ena_log` formatted message. Tx/Rx data path logs are now printed via `ena_log_io`. This allows them to be conditionally compiled out, depending on the presence of ENA_LOG_IO_ENABLE compilation flag. By default this flag is disabled. All `ena_trc_*` ena_com level messages are now also wrapped around `ena_log` and require `ena_dev->dmadev` to be present. There are four log levels: * 0 - ENA_ERR - enable driver error messages and ena_com error logs, * 1 - ENA_WARN - enable logs for non-critical errors, * 2 - ENA_INFO - make the driver more verbose about its actions, * 3 - ENA_DBG - enable debug logs Please see `ena_fbsd_log.h` for implementation details.

ena-com: Fix ena-com to allocate cdesc aligned to 4k

2020-11-18T14:30:59Z

The latest generation hardware requires IO CQ (completion queue) descriptors memory to be aligned to a 4K. It needs that feature for the best performance. Allocating unaligned descriptors will have a big performance impact as the packet processing in a HW won't be optimized properly. It's a critical fix, especially for the arm64 EC2 instances.

Upgrade ENA HAL to the version from 20.04.2020

2020-05-26T15:04:49Z

This version of the HAL supports newest generation ENA HW, random RSS generation upon device initialization and also includes bug fixes in the platform file, like fix for IO write/read macros regarding using barriers. Submitted by: Michal Krawczyk Obtained from: Semihalf Sponsored by: Amazon, Inc.

Update ena-com for the ENAv2 version

2019-05-30T12:27:55Z

The new ena-com is required for the ENAv2 release of the driver. Genmask macro was fixed in the platform file. The GENMASK macro is intended to work on 32-bit values. Before this patch the, calling GENMASK(31, 0) would cause 32-bit value to be shifted by 32. This could lead to unexpected behavior, as shifting by the number greater or equal to word length is undefined operation.
