Current MD file explains this port of BLIS to Apple's matrix coprocessor.
- Here is the original BLIS README.
As of Jul., 2021, the coprocessor is undocumented but not protected either. (Any user / program is allowed to invoke this coprocessor and it's supposed to be safe.) This work is based on Dougall Johnson's effort on analyzing the related instructions.
Known issues:
- Generic-strided is not supported by our microkernels for the destination matrix. Program would
assert(false)upon encountering such a situation. - TRSM might fail. Try commenting out function call to
bli_cntx_set_packm_kersinconfig/aaplmx/bli_cntx_init_aaplmx.cif your need TRSM to work.
Performance:
