Pull request overview
Adds a server-side workaround to default MOE_USE_MICRO_GEMM_PREFILL=0 when not already set, intended to mitigate a Qwen3 MoE concurrency issue (noted as iGPU-related) during OVMS startup.
Changes:
- Set
MOE_USE_MICRO_GEMM_PREFILLto"0"at process start if the variable is not present. - Apply the workaround in the CLI startup path (
Server::start(argc, argv)).
