[Fix] Capability for Realtek WiFi TX power tables load and report from RFE (RF front end) parameters is needed. Multiple commits from vanilla kernel. [Test Case] ``` $ sudo iw reg set CN # manually connect to 5G ap : center channel 155 bw 80 M $ sudo cat /sys/kernel/debug/ieee80211/phy0/rtw89/txpwr_table | grep -E 'MCS_2TX_80M_0|Regulatory' ``` The expected output s ``` Regulatory: CN MCS_2TX_80M_0 - NON_BF BF | 10, 9, dbm ``` And verification fail output: ``` Regulatory: CN MCS_2TX_80M_0 - NON_BF BF | 15, 10, dbm ``` [Where problems could occur] This updates the behaviors and constraints of radio device power transmission for rtw89 driver, and must be done for regulatory compliance. [Other Info] As needed for oem-6.5/jammy, nominate only for Noble and oem-6.5/jammy. ========== original bug report ========== New China SRRC compliance readiness check Proposed Change: - China SRRC updates the testing requirement for 2.4/5GHz, the major changes are the in-band RSE limit, and EIRP limits. - The SRRC updates impact both WLAN modules and platforms. The WLAN modules need to complete the new SRRC testing then platform can start to apply / renew the new SRRC cert. If platform took several WLAN modules but not all of the modules have completed the new SRRC testing updates, platform cannot renew/apply the new SRRC cert. - The platforms which apply/renew SRRC new standards need to ensure the TX power can meet the new RSE/EIRP limits. IHV confirmed below driver version can support these requirements. Realtek: The upstream driver can support SRRC compliance. https://lore.kernel.org/linux-wireless/20230927072156.26336-1-pks...@realtek.com/T/#m4d8acb2697ff2bc07485a6119839e1f96a822340 [lore.kernel.org] To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2043964/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
