Subject: [PATCH v5 5/7] ptp: ptp_vmclock: add 'VMCLOCK' to ACPI device match
Date: Wed, 7 Jan 2026 13:26:12 +0000 [thread overview]
Message-ID: <20260107132514.437-6-bchalios@amazon.es> (raw)
In-Reply-To: <20260107132514.437-1-bchalios@amazon.es>
From: David Woodhouse <dwmw@amazon•co.uk>
As we finalised the spec, we spotted that vmgenid actually says that the
_HID is supposed to be hypervisor-specific. Although in the 13 years
since the original vmgenid doc was published, nobody seems to have cared
about using _HID to distinguish between implementations on different
hypervisors, and we only ever use the _CID.
For consistency, match the _CID of "VMCLOCK" too.
