Subject: [PATCH v2 0/2] Support clean reboot after hibernate on Arm64
Date: Mon, 11 Mar 2024 12:19:14 +0000 [thread overview]
Message-ID: <20240412073530.2222496-1-dwmw2@infradead.org> (raw)
When the hardware signature in the ACPI FACS changes, the OS is supposed
to perform a clean reboot instead of attempting to resume on a changed
platform.
Although these patches have a functional dependency, they could be merged
separately. The second patch just won't *see* a FACS table if the ACPICA
fix isn't present.
v2: Now that the ACPICA patch is merged upstream, note its commit ID
David Woodhouse (2):
ACPICA: Detect FACS even for hardware reduced platforms
arm64: acpi: Honour firmware_signature field of FACS, if it exists
