Discussion

If this is a relatively large or complex change, feel free to start a discussion by explaining why you chose the solution you did and what alternatives you considered

Please note that 2 function call to the flatmm will result in duplicated call to buffer load matrix A, which will reduce the overall performance. This will be a temporary solution to unblock gate+up, but as a production I think need carefully consider change the flatmm inline asm block to support both gate+up and gate before merge into the mainline
