8 daysnet: airoha: Remove airoha_dev_stop() in airoha_remove()Lorenzo Bianconi
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.

2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
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 <kees@kernel.org>
2026-01-21net: airoha: npu: Add the capability to read firmware names from dtsLorenzo Bianconi
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.

2026-01-20net: airoha_eth: increase max MTU to 9220 for DSA jumbo framesSayantan Nandy
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.

Rely on airoha_eth struct in airoha_ppe_flow_offload_cmd routine signature and in all the called subroutines. This is a preliminary patch to introduce flowtable offload for traffic received by the wlan NIC and forwarded to the ethernet one.

2025-08-21net: airoha: ppe: Do not invalid PPE entries in case of SW hash collisionLorenzo Bianconi
SW hash computed by airoha_ppe_foe_get_entry_hash routine (used for foe_flow hlist) can theoretically produce collisions between two different HW PPE entries. In airoha_ppe_foe_insert_entry() if the collision occurs we will mark the second PPE entry in the list as stale (setting the hw hash to 0xffff). Stale entries are no more updated in airoha_ppe_foe_flow_entry_update routine and so they are removed by Netfilter. Fix the problem not marking the second entry as stale in airoha_ppe_foe_insert_entry routine if we have already inserted the brand new entry in the PPE table and let Netfilter remove real stale entries according to their timestamp. Please note this is just a theoretical issue spotted reviewing the code and not faced running the system.

Read all NPU wlan IRQ lines from the NPU device-tree node. NPU module fires wlan irq lines when the traffic to/from the WiFi NIC is not hw accelerated (these interrupts will be consumed by the MT76 driver in subsequent patches).
