Subject: [PATCH v3 2/3] ACPI/table: Print MADT Wake table information
Date: Sun, 25 Apr 2021 19:39:40 -0700 [thread overview]
Message-ID: <20210426023941.729334-3-sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
In-Reply-To: <20210426023941.729334-1-sathyanarayanan.kuppuswamy@linux.intel.com>
When MADT is parsed, print MADT Wake table information as
debug message. It will be useful to debug CPU boot issues
related to MADT wake table.
