Subject: [PATCHv4 12/14] x86/acpi: Rename fields in acpi_madt_multiproc_wakeup structure
Date: Tue, 5 Dec 2023 03:45:08 +0300 [thread overview]
Message-ID: <20231205004510.27164-13-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20231205004510.27164-1-kirill.shutemov@linux.intel.com>
To prepare for the addition of support for MADT wakeup structure version
1, it is necessary to provide more appropriate names for the fields in
the structure.
The field 'mailbox_version' renamed as 'version'. This field signifies
the version of the structure and the related protocols, rather than the
version of the mailbox. This field has not been utilized in the code
thus far.
The field 'base_address' renamed as 'mailbox_address' to clarify the
kind of address it represents. In version 1, the structure includes the
reset vector address. Clear and distinct naming helps to prevent any
confusion.
