Subject: [PATCH 2/7] cxl: Remove unused values in bare-metal environment.
Date: Wed, 1 Feb 2017 18:30:08 +0100 [thread overview]
Message-ID: <1485970213-25532-3-git-send-email-clombard@linux.vnet.ibm.com> (raw)
In-Reply-To: <1485970213-25532-1-git-send-email-clombard@linux.vnet.ibm.com>
The two fields pid and tid of the structure cxl_irq_info are only used
in the guest environment. To avoid confusion, it's not necessary
to fill the fields in the bare-metal environment.
The PSL Process and Thread Identification Register is only used when
attaching a dedicated process for PSL8 only.
