linux-stable.git/include/linux/soc/airoha, branch v6.18.2 Linux kernel stable tree net: airoha: npu: Add a NPU callback to initialize flow stats 2025-09-27T00:29:54+00:00 Lorenzo Bianconi lorenzo@kernel.org 2025-09-24T21:14:53+00:00 105ce7ad57e492b75ab40f2dc591db645fadbaa2 Introduce a NPU callback to initialize flow stats and remove NPU stats initialization from airoha_npu_get routine. Add num_stats_entries to airoha_npu_ppe_stats_setup routine. This patch makes the code more readable since NPU statistic are now initialized on demand by the NPU consumer (at the moment NPU statistic are configured just by the airoha_eth driver). Moreover this patch allows the NPU consumer (PPE module) to explicitly enable/disable NPU flow stats.
