Add mt76u_alloc_mcu_queue utility routine to allocate mcu hw rx queue. This is a preliminary patch to support new devices (e.g. mt7663u) that rely on a hw queue for mcu messages Co-developed-by: Sean Wang <sean.wang@xxxxxxxxxxxx> Signed-off-by: Sean Wang <sean.wang@xxxxxxxxxxxx> Signed-off-by: Lorenzo Bianconi <lorenzo@xxxxxxxxxx> --- drivers/net/wireless/mediatek/mt76/mt76.h | 1 + drivers/net/wireless/mediatek/mt76/usb.c | 6 ++++++ 2 files changed, 7 insertions(+) diff --git a/drivers/net/wireless/mediatek/mt76/mt76.h b/drivers/net/wireless/mediatek/mt76/mt76.h index 217f8c5ad201..d58d76e31a84 100644 --- a/drivers/net/wireless/mediatek/mt76/mt76.h +++ b/drivers/net/wireless/mediatek/mt76/mt76.h @@ -889,6 +889,7 @@ void mt76u_single_wr(struct mt76_dev *dev, const u8 req, const u16 offset, const u32 val); int mt76u_init(struct mt76_dev *dev, struct usb_interface *intf); void mt76u_deinit(struct mt76_dev *dev); +int mt76u_alloc_mcu_queue(struct mt76_dev *dev); int mt76u_alloc_queues(struct mt76_dev *dev); void mt76u_stop_tx(struct mt76_dev *dev); void mt76u_stop_rx(struct mt76_dev *dev); diff --git a/drivers/net/wireless/mediatek/mt76/usb.c b/drivers/net/wireless/mediatek/mt76/usb.c index d85268c6df70..4e0a115c6fd2 100644 --- a/drivers/net/wireless/mediatek/mt76/usb.c +++ b/drivers/net/wireless/mediatek/mt76/usb.c @@ -629,6 +629,12 @@ mt76u_alloc_rx_queue(struct mt76_dev *dev, enum mt76_rxq_id qid) return mt76u_submit_rx_buffers(dev, qid); } +int mt76u_alloc_mcu_queue(struct mt76_dev *dev) +{ + return mt76u_alloc_rx_queue(dev, MT_RXQ_MCU); +} +EXPORT_SYMBOL_GPL(mt76u_alloc_mcu_queue); + static void mt76u_free_rx_queue(struct mt76_dev *dev, struct mt76_queue *q) { -- 2.21.1
