wifi: ath11k: Use dma_alloc_noncoherent for rx_tid buffer allocation

2025-05-29T09:13:45+00:00

[ Upstream commit eeadc6baf8b3dcd32787cc84f0473dc2a2850370 ]

Currently, the driver allocates cacheable DMA buffers for the rx_tid
structure using kzalloc() and dma_map_single(). These buffers are
long-lived and can persist for the lifetime of the peer, which is not
advisable. Instead of using kzalloc() and dma_map_single() for allocating
cacheable DMA buffers, utilize the dma_alloc_noncoherent() helper for the
allocation of long-lived cacheable DMA buffers, such as the peer's rx_tid.
Since dma_alloc_noncoherent() returns unaligned physical and virtual
addresses, align them internally before use within the driver. This
ensures proper allocation of non-coherent memory through the kernel
helper.

wifi: ath12k: report station mode transmit rate

2025-05-29T09:13:44+00:00

[ Upstream commit 8a9c06b40882ebea45563059ddc5d57acdec9dda ]

Currently, the transmit rate of "iw dev xxx station dump" command
always show an invalid value.

To address this issue, ath12k parse the info of transmit complete
report from firmware and indicate the transmit rate to mac80211.

This patch affects the station mode of WCN7850 and QCN9274.

After that, "iw dev xxx station dump" show the correct transmit rate.
Such as:

wifi: ath12k: report station mode receive rate for IEEE 802.11be

2025-05-29T09:13:44+00:00

[ Upstream commit 5e73276c814fc1a5a1bce6be743e1a07baa6d4bc ]

Currently, the receive rate of EHT of "iw dev xxx station dump" command
always show an invalid value.

This is because ath12k does not pass information about the rx_status of EHT
to mac80211. So, mac80211 not calculate the receive rate.

To address this issue, add logic for handling rx_status of EHT to the
ath12k_dp_rx_h_rate() function.

After that, "iw dev xxx station dump" show the correct receive rate.
Such as:

Station 00:03:7f:12:03:03 (on wlo1)
        inactive time:  48 ms

wifi: ath12k: Fix end offset bit definition in monitor ring descriptor

2025-05-29T09:13:44+00:00

[ Upstream commit 6788a666000d600bd8f2e9f991cad9cc805e7f01 ]

End offset for the monitor destination ring descriptor is defined as
16 bits, while the firmware definition specifies only 12 bits.
The remaining bits (bit 12 to bit 15) are reserved and may contain
junk values, leading to invalid information retrieval. Fix this issue
by updating the correct genmask values.

wifi: ath9k: return by of_get_mac_address

[ Upstream commit dfffb317519f88534bb82797f055f0a2fd867e7b ]

When using nvmem, ath9k could potentially be loaded before nvmem, which
loads after mtd. This is an issue if DT contains an nvmem mac address.

If nvmem is not ready in time for ath9k, -EPROBE_DEFER is returned. Pass
it to _probe so that ath9k can properly grab a potentially present MAC
address.

flags to tcl_ext_cmd->info1, we initialize + override. This will be needed
in the future to make broadcast frames work with ethernet encapsulation.

wifi: ath12k: Avoid napi_sync() before napi_enable()

2025-05-29T09:13:40+00:00

[ Upstream commit 268c73d470a5790a492a2fc2ded084b909d144f3 ]

In case of MHI error a reset work will be queued which will try
napi_disable() after napi_synchronize().

As the napi will be only enabled after qmi_firmware_ready event,
trying napi_synchronize() before napi_enable() will result in
indefinite sleep in case of a firmware crash in QMI init sequence.

To avoid this, introduce napi_enabled flag to check if napi is enabled
or not before calling napi_synchronize().

Currently, peer id get reported in the PPDU end user TLV tag. But the
monitor status handler is inherited from ath11k, but it was not updated
to incorporate the changes made to ath12k 802.11be hardware architecture.
Therefore, update the peer id from the PPDU end user TLV data to get latest
peer id update, it helps to populate accurate peer information on the
statistics data.
