* hexagon: add async HMX worker Introduce hmx-worker (dedicated thread for HMX compute) to overlap HMX matmul with HVX dequant/DMA stages in the pipeline path, replacing the previous synchronous HMX calls that blocked the main thread. * hexagon: cost-based VTCM chunk search for out-stationary matmul * hexagon: fix futex race in hmx_worker_drain Store the boolean to local variable avoid atomic load twice * hex-mm: hmx optimize scatter/transpose and use HMX intrinsics * hex-vmem: drop vmem limit a touch under 3GB on v73 * hexagon: add fwd declaration of htp_context * hex-hmx: replace hmx-worker with hmx-queue that mimics dma-queue interface Simplifies the overall implemantion, reduces thread wakeup roundtrips. * hex-mm: add debug log to hmx work func called from hmx-queue * Update hmx-queue.h Co-authored-by: Max Krasnyansky <max.krasnyansky@gmail.com> --------- Co-authored-by: Kim-Chyan Gan <kgan@qti.qualcomm.com> Co-authored-by: Max Krasnyansky <maxk@qti.qualcomm.com> Co-authored-by: Max Krasnyansky <max.krasnyansky@gmail.com> |
