Subject: Re: [PATCH v2] usb: xhci-pci: Add AMD 600 series to xhci-pci-prom21
Date: Sat, 5 Sep 2026 03:35:32 +0200 [thread overview]
Message-ID: <6e81b0fa-de68-4a83-a152-fe26ea7cc359@gmx.de> (raw)
Tested on an MSI MPG X670E Carbon WiFi (Ryzen 9 7950X3D). The board
exposes two 600 series chipset xHCI functions, 1022:43f7 at 13:00.0 and
15:00.0 -- X670E is built from two Promontory 21 dies.
Without the patch neither function creates an auxiliary device, so
prom21-xhci has nothing to bind to and the sensor is unavailable. With
it applied to 7.2.3, both functions bind xhci-pci-prom21, both auxiliary
devices appear, and both dies report:
prom21_xhci-pci-1300 temp1: +57.4 C
prom21_xhci-pci-1500 temp1: +62.8 C
k10temp Tctl read +58.0 C at the same moment, so the conversion derived
on 800 series silicon looks right here too.
USB is unaffected: the devices behind both controllers enumerate
normally and the log shows no new xHCI errors after they moved to the
glue driver.
