Subject: [PATCH v2 05/14] ppc/xive2: Dump more NVP state with 'info pic'
Date: Mon,  9 Sep 2024 16:10:29 -0500	[thread overview]
Message-ID: <20240909211038.27440-6-kowal@linux.ibm.com> (raw)
In-Reply-To: <20240909211038.27440-1-kowal@linux.ibm.com>

From: Frederic Barrat <fbarrat@linux.ibm.com>

The 'PGoFirst' field of a Notify Virtual Processor tells if the NVP
belongs to a VP group.

Also, print the Reporting Cache Line address, if defined.
