Gordon Fossum	bb2f52844b	powerpc: Optimized ZGEMM kernel for POWER10 This patch introduces new optimized version of ZGEMM kernel using power10 Matrix-Multiply Assist (MMA) feature introduced in POWER ISA v3.1. This patch makes use of new POWER10 compute instructions for matrix multiplication operation. Tested on simulator and there are no new test failures. Cycles count reduced by 30-50% compared to POWER9 version depending on M/N/K sizes.	6 years ago
