2022-02-24mt76: mt7915: introduce band_idx in mt7915_phyBo Jiao1-12/+16
The wfsys of MT7986 has only single adie chip for non-dbdc devices, and it binds to band1 by default. Hence this patch adds band_idx to explicitly configure phy accordingly.

2021-06-19mt76: reduce rx buffer size to 2048Lorenzo Bianconi1-7/+5

2021-06-17mt76: mt7915: move mt7915_queue_rx_skb to mac.cFelix Fietkau1-33/+0
It is not really DMA specific, and moving it makes it possible to make some functions in mac.c static Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-04-21mt76: dma: add the capability to define a custom rx napi poll routineLorenzo Bianconi1-1/+1

2021-04-13mt76: mt7915: add mmio.cRyder Lee1-108/+0
Add mmio.c in order to use mt76_bus_ops throughout the driver. It will be also shared with the future APSoC revision. Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-04-12mt76: use threaded NAPIFelix Fietkau1-1/+1
With threaded NAPI, the rx handler function is no longer bound to the CPU that fired the interrupt, which significantly helps to spread the workload over multiple CPUs, especially when multiple devices are using threaded NAPI at the same time. Exclude the tx handler from threaded NAPI by using a separate dummy netdev. The work is small and short-lived enough that it makes more sense to run it in softirq instead of creating a dedicated thread Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-01-27mt76: mt7915: add support for using a secondary PCIe link for gen1Felix Fietkau1-30/+66
For performance reasons, mt7915 supports using 2 PCIE gen1 links on platforms that don't support gen2. Add support for using this to move traffic for a second DBDC band onto a dedicated link Signed-off-by: Felix Fietkau <nbd@nbd.name>
2021-01-27mt76: mt7915: bring up the WA event rx queue for band1Felix Fietkau1-0/+8

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2020-09-24mt76: convert from tx tasklet to tx worker threadFelix Fietkau1-1/+0
This improves performance by allowing the scheduler to move the tx scheduling work to idle CPUs. Since tx scheduling work is very latency sensitive and kept short via AQL, sched_set_fifo_low is used to keep worker priority above normal tasks Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: remove struct mt76_sw_queueFelix Fietkau1-14/+7

2020-09-24mt76: mt7915: add support for accessing mapped registers via bus opsFelix Fietkau1-0/+108

2020-09-24mt76: mt7915: significantly reduce interrupt loadFelix Fietkau1-4/+2
On 7615 and newer, DMA completion only triggers unmap, but not free of queued skbs, since pointers to packets are queued internally. Because of that, there is no need to process the main data queue immediately on DMA completion. To improve performance, mask out the DMA data queue completion interrupt and process the queue only when we receive a txfree event. This brings the number of interrupts under load down to a small fraction. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7915: schedule tx tasklet in mt7915_mac_tx_freeFelix Fietkau1-2/+0
The previous scheduling round may have been limited by AQL. More frames might be available after the tx free run. Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7915: optimize mt7915_mac_sta_pollFelix Fietkau1-1/+0
Since DMA completion does not imply tx completion, it makes more sense to poll for airtime from mt7915_mac_tx_free. Reduce the runtime of the function by moving all items from dev->sta_poll_list to a local list once and process any stations that were added afterwards on the next run Signed-off-by: Felix Fietkau <nbd@nbd.name>
2020-09-24mt76: mt7915: do not do any work in napi poll after calling napi_complete_done()Felix Fietkau1-6/+3
