Some ath10k firmware versions allow to access the chip internal a temperature sensor and allow to reduce the amount of the time when the card is allowed to send. The latter is required on devices which tend to overheat. An userspace service has to read /sys/class/ieee80211/phy*/device/hwmon/hwmon*/temp1_input regularly and then decide how much the device has to be throttled. This can be done by writing to /sys/class/ieee80211/phy*/device/cooling_device/cur_state. By default it is not throttled (0) but it can be throttled up to 100(%).

Subject: [PATCH 2/2] ath10k: move spectral scan support under a separate
|
|
config symbol
|
|
|
|
At the moment, spectral scan support, and with it RELAY, is always enabled
|
|
with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
|
|
RELAY in ath10k, and it unconditionally reserves a relay channel.
|
|
|
|
Having debugfs support in ath10k is often useful even on very small
|
|
embedded routers, where we'd rather like to avoid the code size and RAM
|
|
usage of the relay support. While ath10k-based devices usually have more
|
|
resources than ath9k-based ones, it makes sense to keep the configuration
|
|
symmetric to ath9k, so the same base kernel without RELAY can be used for
|
|
both ath9k and ath10k hardware.
