Subject: [PATCH v2 1/2] drivers: fix build warnings when using icx
Date: Wed,  5 Feb 2025 18:29:14 +0000	[thread overview]
Message-ID: <20250205182918.4041268-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20250205182918.4041268-1-bruce.richardson@intel.com>

The Intel oneAPI DPC++/C++ Compiler (icx), issues warnings on build when
the "-march=native", or other configured global "-march" flag, is
overridden to "skylake-avx512", when compiling AVX-512 code.

Allow building with icx with warnings-as-errors flag (werror) enabled by
disabling the warning for the cases where we pass that extra "-march"
flag.

Fixes: e6a6a138919f ("net/i40e: add AVX512 vector path")
Fixes: 31737f2b66fb ("net/iavf: enable AVX512 for legacy Rx")
Fixes: 7f85d5ebcfe1 ("net/ice: add AVX512 vector path")
Fixes: 0fac6a1c44d5 ("common/idpf: add AVX512 for single queue model")
