Subject: [PATCH 0/2] wifi: rtw89: fix RF calibration for USB transport
Date: Fri, 10 Apr 2026 10:00:15 +0200 [thread overview]
Message-ID: <20260410080017.82946-1-loukot@gmail.com> (raw)
In-Reply-To: <795a8567fdbe48babc5cf0f2b5e10c0a@realtek.com>
RF calibration on USB adapters (RTL8922AU) fails frequently because the
timeout values in rtw89_phy_rfk_report_wait() are designed for PCIe and
too tight for USB H2C/C2H round-trip latency.
Patch 1 applies a 4x timeout multiplier for USB devices, based on
measured calibration times from two independent testers across 2.4GHz,
5GHz, and 6GHz bands.
Patch 2 makes calibration timeouts non-fatal on USB, since the radio
continues to operate correctly despite occasional incomplete
calibrations. PCIe error handling is unchanged.
This is based on Ping-Ke's suggestion in the RTL8922AU support thread:
