Subject: [PATCH 2/9] ARM: mach-ux500: use SGI0 to wake up the other core
Date: Tue, 20 Nov 2012 20:58:26 -0600 [thread overview]
Message-ID: <1353466713-18967-3-git-send-email-robherring2@gmail.com> (raw)
In-Reply-To: <1353466713-18967-1-git-send-email-robherring2@gmail.com>
From: Srinidhi Kasagar <srinidhi.kasagar@stericsson.com>
The commit 7d28e3eaa1a8e951251b942e7220f97114bd73b9
("ARM: ux500: wake secondary cpu via resched") makes use
of schedule IPI to wake up the secondary core which seems
incorrect. Rather use SGI0.
