Subject: [dpdk-dev] [PATCH v2] eal/cpuflags: add x86 based cpu flags
Date: Wed, 25 Mar 2020 11:10:16 +0000
Message-ID: <20200325111016.29163-1-kevin.laatz@intel.com> (raw)
In-Reply-To: <20200324114921.7184-1-kevin.laatz@intel.com>

This patch adds CPU flags which will enable the detection of ISA
features available on more recent x86 based CPUs.

The CPUID leaf information can be found in Section 1.7 of this
document:
https://software.intel.com/sites/default/files/managed/c5/15/architecture-instruction-set-extensions-programming-reference.pdf

The following CPU flags are added in this patch:
    - AVX-512 doubleword and quadword instructions.
    - AVX-512 integer fused multiply-add instructions.
    - AVX-512 conflict detection instructions.
    - AVX-512 byte and word instructions.
    - AVX-512 vector length instructions.
    - AVX-512 vector bit manipulation instructions.
    - AVX-512 vector bit manipulation 2 instructions.
    - Galois field new instructions.
    - Vector AES instructions.
    - Vector carry-less multiply instructions.
    - AVX-512 vector neural network instructions.
    - AVX-512 for bit algorithm instructions.
    - AVX-512 vector popcount instructions.
    - Cache line demote instructions.
    - Direct store instructions.
    - Direct store 64B instructions.
    - AVX-512 two register intersection instructions.
