Then the tx completes will take over +the scheduling. When amsdu and ampdu is used the frames are +transferred wireless in a very bulky fashion, in combination +with this scheduling algorithm and buffer limiters in the stack +this can result in limited throughput. This change causes the +flow worker to be scheduled more frequently from tx. + +Reviewed-by: Arend Van Spriel <arend@broadcom.com> +Reviewed-by: Franky (Zhenhui) Lin <frankyl@broadcom.com> +Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> +Reviewed-by: Daniel (Deognyoun) Kim <dekim@broadcom.com> +Signed-off-by: Hante Meuleman <meuleman@broadcom.com> +Signed-off-by: Arend van Spriel <arend@broadcom.com> +Signed-off-by: Kalle Valo <kvalo@codeaurora.org> +--- + +--- a/drivers/net/wireless/brcm80211/brcmfmac/flowring.c ++++ b/drivers/net/wireless/brcm80211/brcmfmac/flowring.c +@@ -249,8 +249,8 @@ void brcmf_flowring_delete(struct brcmf_ + } + + +-void brcmf_flowring_enqueue(struct brcmf_flowring *flow, u8 flowid, +- struct sk_buff *skb) ++u32 brcmf_flowring_enqueue(struct brcmf_flowring *flow, u8 flowid, ++ struct sk_buff *skb) + { + struct brcmf_flowring_ring *ring; + +@@ -271,6 +271,7 @@ void brcmf_flowring_enqueue(struct brcmf + if (skb_queue_len(&ring->skblist) < BRCMF_FLOWRING_LOW) + brcmf_flowring_block(flow, flowid, false); + } ++ return skb_queue_len(&ring->skblist); + } + + +--- a/drivers/net/wireless/brcm80211/brcmfmac/flowring.h ++++ b/drivers/net/wireless/brcm80211/brcmfmac/flowring.h +@@ -64,8 +64,8 @@ u32 brcmf_flowring_create(struct brcmf_f + void brcmf_flowring_delete(struct brcmf_flowring *flow, u8 flowid); + void brcmf_flowring_open(struct brcmf_flowring *flow, u8 flowid); + u8 brcmf_flowring_tid(struct brcmf_flowring *flow, u8 flowid); +-void brcmf_flowring_enqueue(struct brcmf_flowring *flow, u8 flowid, +- struct sk_buff *skb); ++u32 brcmf_flowring_enqueue(struct brcmf_flowring *flow, u8 flowid, ++ struct sk_buff *skb); + struct sk_buff *brcmf_flowring_dequeue(struct brcmf_flowring *flow, u8 flowid); + void brcmf_flowring_reinsert(struct brcmf_flowring *flow, u8 flowid, + struct sk_buff *skb); +--- a/drivers/net/wireless/brcm80211/brcmfmac/msgbuf.c ++++ b/drivers/net/wireless/brcm80211/brcmfmac/msgbuf.c +@@ -73,7 +73,7 @@ + #define BRCMF_MSGBUF_TX_FLUSH_CNT1 32 + #define BRCMF_MSGBUF_TX_FLUSH_CNT2 96 + +-#define BRCMF_MSGBUF_DELAY_TXWORKER_THRS 64 ++#define BRCMF_MSGBUF_DELAY_TXWORKER_THRS 96 + #define BRCMF_MSGBUF_TRICKLE_TXWORKER_THRS 32 + + struct msgbuf_common_hdr { +@@ -797,6 +797,8 @@ static int brcmf_msgbuf_txdata(struct br + struct brcmf_flowring *flow = msgbuf->flow; + struct ethhdr *eh = (struct ethhdr *)(skb->data); + u32 flowid; ++ u32 queue_count; ++ bool force; + + flowid = brcmf_flowring_lookup(flow, eh->h_dest, skb->priority, ifidx); + if (flowid == BRCMF_FLOWRING_INVALID_ID) { +@@ -804,8 +806,9 @@ static int brcmf_msgbuf_txdata(struct br + if (flowid == BRCMF_FLOWRING_INVALID_ID) + return -ENOMEM; + } +- brcmf_flowring_enqueue(flow, flowid, skb); +- brcmf_msgbuf_schedule_txdata(msgbuf, flowid, false); ++ queue_count = brcmf_flowring_enqueue(flow, flowid, skb); ++ force = ((queue_count % BRCMF_MSGBUF_TRICKLE_TXWORKER_THRS) == 0); ++ brcmf_msgbuf_schedule_txdata(msgbuf, flowid, force); + + return 0; + } |
