Subject: [PATCH V2 1/6] cxl: Remove unused values in bare-metal environment.
Date: Tue, 14 Mar 2017 12:08:37 +0100 [thread overview]
Message-ID: <1489489722-935-2-git-send-email-clombard@linux.vnet.ibm.com> (raw)
In-Reply-To: <1489489722-935-1-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.
