[PATCH 9/9] ath10k: combine txrx and replenish task

Since tx completion and rx indication processing are moved out of txrx tasklet and rx ring lock contention also removed from txrx for rx_ind messages, it would be efficient to combine both replenish and txrx tasks. Refill threshold is adjusted for both AP135 and AP148 (low and high end systems).

[PATCH 5/9] ath10k: speedup htt rx descriptor processing for rx_ind

In follow up patch, htt rx descriptors will be reused instead of dealloc and refill. To achieve that htt rx indication messages should not be deferred and should be processed in pci tasklet itself. Also from rx indication message, mpdu_count alone is used. So it is maintained as atomic variable

[PATCH 6/9] ath10k: register ath10k_htt_htc_t2h_msg_handler

Except qca61x4 family chips (qca6164, qca6174), copy engine 5 is used for receiving target to host htt messages. In follow up patch, CE5 descriptors will be reused. In such case, same API can not be used as htc layer callback where the response messages will be freed at the end. Hence register new

[PATCH 7/9] ath10k: cleanup copy engine receive next completion

The physical address necessary to unmap DMA ('bufferp') is stored in ath10k_skb_cb as 'paddr'. For diag register read and write operations, 'paddr' is stored in transfer context. ath10k doesn't rely on the meta/transfer_id. So the unused output arguments {bufferp, nbytesp and transfer_idp} are

[PATCH 1/9] ath10k: speedup htt rx descriptor processing for tx completion

To optimize CPU usage htt rx descriptors will be reused instead of refilling it for htt rx copy engine (CE5). To support that all htt rx indications should be processed at same context. FIFO queue is used to maintain tx completion status for each msdu. This helps to retain the order of tx

[PATCH 4/9] ath10k: cleanup amsdu processing for rx indication

Make amsdu handlers (i.e amsdu_pop and rx_h_handler) common to both rx_ind and frag_ind htt events. It is sufficient to hold rx_ring lock for amsdu_pop alone and no need to hold it until the packets are delivered to mac80211. This helps to reduce rx_lock contention as well. Signed-off-by:

[PATCH 3/9] ath10k: remove unused fw_desc processing

The fw descriptor was never used and probably never will be. It makes little sense to maintain support for it. Remove it and simplify rx processing. This will make it easier to optimize rx processing later as well. Signed-off-by: Rajkumar Manoharan ---

[PATCH 0/9] ath10k: improve throughput performance

Hi All, In order to reuse HTT Rx descriptor (copy engine 5), HTT response processing should be decoupled from txrx data processing. This change also helps to reduce rx ring lock contention. As txrx tasklet's work load is reduced, rx replenish task can be combined with txrx_task. Refilling
