From e2a39697fb0a382c3503460d9fb41ca72ca05bae Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Wed, 15 Jan 2020 11:58:53 +0100 Subject: [PATCH] mt76: mt76u: introduce mt76u_alloc_mcu_queue utility routine 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 Signed-off-by: Sean Wang Signed-off-by: Lorenzo Bianconi Signed-off-by: Felix Fietkau --- mt76.h | 1 + usb.c | 6 ++++++ 2 files changed, 7 insertions(+) diff --git a/mt76.h b/mt76.h index 8abc4a51..e8d7e5e9 100644 --- a/mt76.h +++ b/mt76.h @@ -885,6 +885,7 @@ 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/usb.c b/usb.c index d85268c6..4e0a115c 100644 --- a/usb.c +++ b/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) {
