Subject: [dpdk-dev] [PATCH v5 7/9] bus/mlx5_pci: register a PCI driver
Date: Thu,  9 Jul 2020 10:34:50 +0300
Message-ID: <20200709073452.948894-8-parav@mellanox.com> (raw)
In-Reply-To: <20200709073452.948894-1-parav@mellanox.com>

Create a mlx5 bus driver framework for invoking drivers of
multiple classes who have registered with the mlx5_pci bus
driver.

Validate user class arguments for supported class combinations.

Changelog:
v3->v4:
 - Fixed dma_map error unwinding flow to follow same order for unmap
v2->v3:
 - Addressed comments from Asaf
 - Using full names in function names
 - Added new line before function name in multiple functions
 - Added example string to parse for multiple classes
 - Dropped mlx5 prefix from static function
 - Addressed comments from Matan.
 - Renamed mlx5_valid_class_combo to mlx5_class_combinations
 - Added cross check for class drivers to support only 3 flags for now
 - Added full stop at the end of comment block.
 - Removed empty lines
 - Fixed issue to remove multiple classes for a driver
 - Using define for drv_flags at multiple places
 - Maintaining class driver list to keep load/unload order symmetric and
   mirror of each other.
 - Deriving drv_flags based on the class drivers
 - Using PCI address comparision helper instead of pointer comparision
 - Fixed alignment for id_table
 - Continue to probe_err if device is already probed
 - Perform dma map on best effort basis for all supported drivers
 - Removed drv_flags check
 - Dynamically build pci id table
 - Using PCI to mlx5 device helper routines
v1->v2:
 - Address comments from Thomas and Gaetan
 - Enhanced driver to honor RTE_PCI_DRV_PROBE_AGAIN drv_flag
 - Use anonymous structure for class search and code changes around it
 - Define static for class comination array
 - Use RTE_DIM to find array size
 - Added OOM check for strdup()
 - Renamed copy variable to nstr_orig
 - Returning negagive error code
 - Returning directly if match entry found
 - Use compat condition check
 - Avoided cutting error message string
 - USe uint32_t datatype instead of enum mlx5_class
 - Changed logic to parse device arguments only once during probe()
 - Added check to fail driver probe if multiple classes register with
   DMA ops
 - Renamed function to parse_class_options
