* wifi: mt76: mt7921: fix a potential association failure upon resumingLeon Yen2024-02-221-0/+2
| | | | | | | | | | | | In multi-channel scenarios, the granted channel must be aborted before suspending. Otherwise, the firmware will be put into a wrong state, resulting in an association failure after resuming. With this patch, the granted channel will be aborted before suspending if necessary.

* wifi: mt76: mt7921s: fix workqueue problem causes STA association failWang Zhao2023-12-071-1/+3
| | | | | | | | | | | | | | | | | | The ieee80211_queue_work function queues work into the mac80211 local->workqueue, which is widely used for mac80211 internal work processes. In the mt76 driver, both the mt76-sido-status and mt76-sdio-net threads enqueue workers to the workqueue with this function. However, in some cases, when two workers are enqueued to the workqueue almost simultaneously, the second worker may not be scheduled immediately and may get stuck for a while. This can cause timing issues. To avoid these timing conflicts caused by worker scheduling, replace the worker with an independent thread.

* wifi: mt76: mt7921: introduce chanctx supportSean Wang2022-12-011-0/+7
| | | | | | | | | | | | | | | | | | | | The firmware can have the capability to manage the channel context scheduling on multiple roles running on the device including Station, AP and P2P GC/GO mode (will be extended based on the future patchset) to help users sharing the network with others on a single device. The firmware is able to support the channel chanctx up to 2 interface simultaneously running on the different channels. Another thing to be noted is that before the driver is going sent out the management frames, the driver has to get the privilege from the firmware to occupy the current channel context until the frame handshake is completed and then get the privilege back to the firmware.

* wifi: mt76: mt7921s: fix race issue between reset and suspend/resumeSean Wang2022-09-151-4/+9
| | | | | | | | | | | | | | | | | | | It is unexpected that the reset work is running simultaneously with the suspend or resume context and it is possible that reset work is still running even after mt7921 is suspended if we don't fix the race issue. Thus, the suspend procedure should be waiting until the reset is completed at the beginning and ignore the subsequent the reset requests. In case there is an error that happens during either suspend or resume handler, we will schedule a reset task to recover the error before returning the error code to ensure we can immediately fix the error there.

* mt76: sdio: honor the largest Tx buffer the hardware can supportSean Wang2022-02-031-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | We don't have to create a separate sdio.xmit_buf buffer for each queue. Instead, we just need to create one, reuse it across all queues to reduce memory consumption further. And then we should take it into account the actual the host and the device MMC capability to determine what the appropriate xmit_buf_size can be. Both MT7921S and MT7663 can support up to Tx FIFO size of 0x3fe00 which means the device can receive 511 blocks of block size 512 in a row from the host. So if the driver aggregates the frames as many as possible the the device can support, we can merge multiple MMC requests into a single one to get rid of the overhead of the handling and synchronizing in those unnecessary MMC requests and reduce the SDIO lock contention with the Bluetooth concurrent traffic and finally to have the higher bus utilization with less idle cycle. With the patch, it is helpful for WiFi to have steady throughput performance especially while running Bluetooth concurrently.
