Subject: Re: [PATCH v2] usb: dwc3: tell xHCI that it lost its state when the core is powered off
Date: Sun, 15 Nov 2026 08:05:58 -0000	[thread overview]
Message-ID: <179472995896.3849457.7552548813153786316@gmail.com> (raw)
In-Reply-To: <20261112141512.1840-1-26rote@gmail.com>

Tested on an Orange Pi 5 (RK3588S, dwc3 not wakeup-capable), 7.3-based
kernel with KASAN and a local dwc3 s2idle change set to keep today's
power-off: 10/10 s2idle cycles reset the controller ("root hub lost
power") and brought a USB 3 disk back; a cycle with the core kept
powered kept its state. No xHC resume error or splat.
