net: airoha: Remove airoha_dev_stop() in airoha_remove()

2026-03-17T03:06:05Z

Do not run airoha_dev_stop routine explicitly in airoha_remove() since ndo_stop() callback is already executed by unregister_netdev() in __dev_close_many routine if necessary and, doing so, we will end up causing an underflow in the qdma users atomic counters. Rely on networking subsystem to stop the device removing the airoha_eth module.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

net: airoha: npu: Add the capability to read firmware names from dts

2026-01-22T03:17:55Z

Introduce the capability to read the firmware binary names from device-tree using the firmware-name property if available. This patch is needed because NPU firmware binaries are board specific since they depend on the MediaTek WiFi chip used on the board (e.g. MT7996 or MT7992) and the WiFi chip version info is not available in the NPU driver. This is a preliminary patch to enable MT76 NPU offloading if the Airoha SoC is equipped with MT7996 (Eagle) WiFi chipset.

net: airoha_eth: increase max MTU to 9220 for DSA jumbo frames

2026-01-21T02:37:11Z

The industry standard jumbo frame MTU is 9216 bytes. When using the DSA subsystem, a 4-byte tag is added to each Ethernet frame. Increase AIROHA_MAX_MTU to 9220 bytes (9216 + 4) so that users can set a standard 9216-byte MTU on DSA ports. The underlying hardware supports significantly larger frame sizes (approximately 16K). However, the maximum MTU is limited to 9220 bytes for now, as this is sufficient to support standard jumbo frames and does not incur additional memory allocation overhead.

net: airoha: Fix schedule while atomic in airoha_ppe_deinit()

2026-01-08T10:23:20Z

airoha_ppe_deinit() runs airoha_npu_ppe_deinit() in atomic context. airoha_npu_ppe_deinit routine allocates ppe_data buffer with GFP_KERNEL flag. Rely on rcu_replace_pointer in airoha_ppe_deinit routine in order to fix schedule while atomic issue in airoha_npu_ppe_deinit() since we do not need atomic context there.
