Subject: [PATCH 1/2] hw/acpi: arm: bump MADT to revision 5
Date: Tue, 28 Mar 2023 11:59:25 -0400	[thread overview]
Message-ID: <20230328155926.2277-2-eric.devolder@oracle.com> (raw)
In-Reply-To: <20230328155926.2277-1-eric.devolder@oracle.com>

Currently ARM QEMU generates, and reports, MADT revision 4. ACPI 6.3
introduces MADT revision 5.

For MADT revision 5, the GICC structure adds an SPE Overflow Interrupt
field. This new 2-byte field is created from the existing 3-byte
Reserved field. The spec indicates if the SPE overflow interrupt is
not supported, to zero the field.
