From f40aaf6da14a4043d6361e0c7d74ada18e866059 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Tue, 10 Jan 2012 17:44:39 +0900 Subject: ARM: mach-shmobile: r8a7779 SMP support V3 This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm Signed-off-by: Paul Mundt --- arch/arm/mach-shmobile/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arm/mach-shmobile/Makefile') diff --git a/arch/arm/mach-shmobile/Makefile b/arch/arm/mach-shmobile/Makefile index 997bd2bcd5f6..7ad6954c46cd 100644 --- a/arch/arm/mach-shmobile/Makefile +++ b/arch/arm/mach-shmobile/Makefile @@ -18,6 +18,7 @@ smp-y := platsmp.o headsmp.o smp-$(CONFIG_HOTPLUG_CPU) += hotplug.o smp-$(CONFIG_LOCAL_TIMERS) += localtimer.o smp-$(CONFIG_ARCH_SH73A0) += smp-sh73a0.o +smp-$(CONFIG_ARCH_R8A7779) += smp-r8a7779.o # Pinmux setup pfc-y := -- cgit v1.2.3
