[PATCH 2/2] ath10k: add debugfs support to configure fwtest parameters

[Anilkumar Kolli]

From: Sathishkumar Muruganandam <murugana@codeaurora.org>

Added a debugfs file "fw_test" to configure the tx parameters
through WMI_FWTEST_CMD

Usage:
cat /sys/kernel/debug/ieee80211/phy0/ath10k/fw_test
echo <param id> <val> > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_test

Added a debugfs file "fw_test" to configure the tx parameters
through WMI_FWTEST_CMD

Usage:
cat /sys/kernel/debug/ieee80211/phy0/ath10k/fw_test
echo <param id> <val> > /sys/kernel/debug/ieee80211/phy0/ath10k/fw_test

Why is it necessary to have these two values in ath10k_debug? They seem to be 
used only in the context of ath10k_write_fw_test().

Where can we find the documentation of the possible param_id and param_values?

Kind regards,

Yes. it is not reused, will remove this.

All these parameters are for experimentation purpose.

It's too lack of information in commit message.
You should add such what values are acceptable for which purpose by each 
param_id and param_value to make this changes meaningful to community.

i agree. i reviewed the firmware sourcecode to find out what its doing, 
but also within the firmware is almost undocumented. its a bunch of 
undocumented
numeric parameters with undocumented behaviour.
if qca is willig to document this feature it might be included.
