The regdomain is self-managed type for ath11k, the regdomain info is
reported from firmware, it is not from wireless regdb. Firmware fetch
the regdomain info from board data file before. Currently most of the
regdomain info has moved to another file regdb.bin from board data
file for some chips such as QCA6390 and WCN6855, so the regdomain info
left in board data file is not enough to support the feature which need
more reg rules such as 6 GHz LPI, SP and VLP.
But for the latter, you are also missing the patch to support the
WMI_REG_CHAN_LIST_CC_EXT_EVENTID (with the 6GHz specific fields in the struct
wmi_reg_chan_list_cc_ext_event)? Otherwise it should not be possible to
get the 6GHz reg rules (which you showed in your commit message).
struct wmi_reg_chan_list_cc_event (for WMI_REG_CHAN_LIST_CC_EVENTID) supports
only 2.4GHz and 5GHz.
WMI_REG_CHAN_LIST_CC_EVENTID also support 6 GHz, But it dose not support
6 GHz LPI, SP and VLP.
I did test with the board-2.bin/m3.bin/amss.bin(without regdb.bin) of this commit
https://github.com/kvalo/ath11k-firmware/commit/0b1d1b2e10f9839ee0675a2ac496bfeb87c304c1.
It only support country US. After added regdb.bin, it support many country.
So regdb.bin is needed now.
Kind regards,
