Declare this function allows us to use customized scanning policy, so each scan takes less time. This is a similar implementation to hw_scan in rtw88, except that we offload more items to firmware and extend the maximum IE length. For backward compatibility, we fallback to sw_scan when firmware does not support this feature. Signed-off-by:

When operating on a mix of DFS and non-DFS channels, the driver only checks the CAC status of the control channel. This causes beacons/tx to fail if the control channel is on a non-DFS channel. Fix this by calling cfg80211_reg_can_beacon to determine the DFS status of all affected channels Signed-off-by:Felix Fietkau <nbd@nbd.name>

By default, mt7915e does not enable thermal management until the default thermal zone does not reach a trip point. If the rest of the system have better cooling than the wireless hardware, then it is possible that the wireless chip can overheat while the rest of the system is fine. Signed-off-by:

The firmware-controlled actual throttle state was previously available by reading the cooling_device, but this confused the thermal subsystem. Add a hwmon attribute to get it instead. Signed-off-by:
-
Nicolas Cavallari authored
mt7915e registers a cooling_device with wrong semantics: 1. cooling_device expect that higher states values should cool more, but mt7915e did the opposite... with the exception of state == 0, which should "disable thermal management", but does not seem to have any effect since the previous state is kept. The result is that when the thermal zone heats up a bit and bumps the cooling_device state from 0 to 1 to cool a bit, the performance is destroyed, and when going back from 1 to 0, the performance stays bad. 2. Reading the cooling_device state does not always return the last written state, but can return the actual hardware throttle state, which is different. This is a problem because the mt7915 firmware actually implement the equivalent of a thermal zone with trip points. Setting the cooling device state actually changes the throttles at each trip point, so the following could occur if the first issue is fixed: - thermal subsystem set state to 100% power (state=0) - mt7915e driver set trip throttles to [100%, 50%, 25%, 12%] - hardware heats up and decides to switch to 50% power - thermal subsystem see that power is 50% (state=50), decide to increase it to 60% (state=40) because the rest of the system is cool. - mt7915e driver set trip throttle to [60%, 30%, 15%, 7%] - hardware thus switches to 30% power [race to the bottom continues...] This patch corrects the semantics of the cooling_device to the one that the thermal subsystem expect it.

Reading through the commit history, it looks like there is no special need why we must skip the first 4 bytes in this trace call: trace_ath10k_htt_rx_desc(ar, (void*)rx_desc + sizeof(u32), hw->rx_desc_ops->rx_desc_size - sizeof(u32)); found in the function ath10k_htt_rx_amsdu_pop in the file htt_rx.c i think the original author (who is also the one who added rx_desc tracing capabilities in a0883cf7) just wanted to trace the rx_desc contents, ignoring the fw_rx_desc_base info field (which is the part being skipped over). But the trace_ath10k_htt_rx_desc later added don't care about skipping it, so it may be good to uniform this call to the others in the file. But this would change the output of the trace and thus it may be a problem for tools that rely on it. Therefore I propose until further discussion to just keep it as it is and just fix the pointer arithmetic bug. Add missing void* cast to rx descriptor pointer in order to properly skip the initial 4 bytes of the rx descriptor when passing it to trace_ath10k_htt_rx_desc trace function. This fixes the pointer arithmetic error detected by Dan Carpenter's static analysis tool.

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

Target copies spectral report and CFR report through dbring to host for further processing. This mechanism involves ring and buffer management in the Host, FW, and uCode, where improper tail pointer update issues are seen. This dbring debug support help to debug such issues by tracking head and tail pointer movement along with the timestamp at which each buffer is received and replenished. Provide a debugfs interface to enalbe/disable dbring debug support and dump the dbring debug entries. Also introduced a new hardware param to add dbring debugfs support for few hardwares which are using dbings. Usage: echo <dbr_id> <val> > /sys/kernel/debug/ath11k/ipq8074_2/ mac0/enable_dbr_debug dbr_id: 0 for spectral and 1 for CFR val: 0 - disable, 1 - enable.
