Section numbering has been updated, and there doesn't seem to be a stable link to a specific version of the doc, recommend to refer to table name instead? Table 1-2. "Information Returned by CPUID Instruction" > 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. > > Signed-off-by: Kevin Laatz <[email protected]> Required a git am --3way due to some file movements in master, but applied cleanly on auto-merge. Add a VNNI documentation line wrap on new line: RTE_CPU_FLAG_AVX512VNNI, /**< AVX512 Vector ... */ With the above changes/updates; Acked-by: Harry van Haaren <[email protected]>
