Subject: Re: [PATCH 0/4] drivers/misc: add Goodix GXFP5130 eSPI fingerprint sensor driver
Date: Thu, 23 Jul 2026 03:07:52 -0700 (PDT) [thread overview]
Message-ID: <6a61e7f8.e11288f4.4669c.c3b1@mx.google.com> (raw)
In-Reply-To: <2026071842-timing-distress-ad5a@gregkh>
I am withdrawing this patch series (v1).
After consulting with Void755, who wrote the original out-of-tree driver
this submission was based on, it became clear that the driver is not ready
for mainline inclusion yet. Specifically:
- The kernel module currently handles sensor-specific protocol logic
(MP protocol, Goodix command structures) that belongs in userspace.
This is consistent with the concern you raised about why a kernel
driver is needed at all.
- A sibling sensor (SIL6250) shares the same eSPI mailbox transport
mechanism. A properly refactored, transport-only kernel driver could
support both sensors, which would make a stronger case for mainline.
- The original author prefers out-of-tree maintenance for now while
the architecture is reworked.
I will resubmit once the kernel/userspace boundary is properly designed
and the driver is in a state the original author considers ready.
Thank you for the detailed review of v1.
