[PATCH 0/2] Add simd optimization with function buffer_is_zero

Posted by Bibo Mao 5 months, 3 weeks ago

On some loongarch machines, simd FPU such lsx/lasx is supported. Here
function buffer_is_zero is optimized with simd FPU supported. 

Bibo Mao (2):
  util: Add lasx cpuinfo for loongarch64
  util/bufferiszero: Add simd acceleration for loongarch64
