The
mlx5_rxtx.cfile contains a lot of Tx burst functions, each of those is performance-optimized for the specific set of requested offloads.
These ones are generated on the basis of the template function and it takes significant time to compile, just due to a large number of giant functions generated in the same file and this compilation is not being done in parallel with using multithreading.Therefore, in this series we split the
mlx5_rxtx.cfile into several separate files to allow different functions to be compiled simultaneously.

Please fix the indentation in meson.build updates. Out of curiosity, what is the gain in compilation time?
Om my development setup, with this patch the partial compilation (for example if we changed the mlx5.h header) takes just several seconds, before one (especially with full debug option) - up to 1 minute - all this this time was eaten by mlx5_rxtx.c.
Also this patch is the preparation step for mlx5 Rx datapath consolidation, we aare thing about implementing the rx_burst template routine as we done for the tx_burst, so - it would be nice to resolve the compilation time issue at early stage.
With best regards,

These ones are generated on the basis of the template function and it takes significant time to compile, just due to a large number of giant functions generated in the same file and this compilation is not being done in parallel with using multithreading.
Therefore we can split the mlx5_rxtx.c file into several separate files to allow different functions to be compiled simultaneously. In this patch, we separate Rx function declarations to different header file in preparation for removing them from the source file and as an optional preparation step for further consolidation of Rx burst functions.

Subject: [PATCH v2 0/6] net/mlx5: reduce Tx datapath compile timeThe
mlx5_rxtx.cfile contains a lot of Tx burst functions, each of those is performance-optimized for the specific set of requested offloads. These ones are generated on the basis of the template function and it takes significant time to compile, just due to a large number of giant functions generated in the same file and this compilation is not being done in parallel with using multithreading.Therefore, in this series we split the
mlx5_rxtx.cfile into several separate files to allow different functions to be compiled simultaneously.v2: fix compilation error + rebase
