MIPS: SMP: Remove plat_smp_ops cpus_done method.

2014-05-27T09:06:42+00:00

Nothing was using the method and there isn't any need for this hook. This leaves smp_cpus_done() empty for the moment. As suggested by Paul Bolle . Signed-off-by: Ralf Baechle

MIPS: Fix warning when including smp-ops.h with CONFIG_SMP=n

2014-03-31T16:17:13+00:00

The gic_send_ipi_mask function declared in smp-ops.h takes a struct cpumask argument, but linux/cpumask.h is only included within an #ifdef CONFIG_SMP. Move the gic_ function declarations within that #ifdef too to fix warnings during build such as: In file included from arch/mips/fw/arc/init.c:15:0: /mnt/buildbot/kernel/mips/slave/mips-linux__allno_/build/arch/mips/include/asm/smp-ops.h:62:44: warning: 'struct cpumask' declared inside parameter list [enabled by default] extern void gic_send_ipi_mask(const struct cpumask *mask, unsigned int action); Reported-by: Markos Chandras Signed-off-by: Paul Burton Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/6655/ Signed-off-by: Ralf Baechle

MIPS: Malta: Make use of generic CM support

MIPS: Coherent Processing System SMP implementation

2014-03-26T22:00:12+00:00

This patch introduces a new SMP implementation for systems implementing the MIPS Coherent Processing System architecture. The kernel will make use of the Coherence Manager, Cluster Power Controller & Global Interrupt Controller in order to detect, bring up & make use of other cores in the system. SMTC is not supported, so only a single TC per VPE in the system is used. That is, this option enables an SMVP style setup but across multiple cores.

MIPS: Move GIC IPI functions out of smp-cmp.c

2014-03-06T20:25:22+00:00

The GIC IPI functions aren't necessarily specific to the "CMP framework" SMP implementation, and will be used elsewhere in a subsequent commit. This patch adds cleaned up GIC IPI functions to a separate file which is compiled when a new CONFIG_MIPS_GIC_IPI Kconfig symbol is selected, and selects that symbol for CONFIG_MIPS_CMP.

MIPS: Malta: Fix crash in SMP kernel on non-CMP systems.

2011-07-20T22:12:10+00:00

Since 6be63bbbdab66b9185dc6f67c8b1bacb6f37f946 (lmo) rsp. af3a1f6f4813907e143f87030cde67a9971db533 (kernel.org) the Malta code does no longer probe for presence of GCMP if CMP is not configured. This means that the variable gcmp_present well be left at its default value of -1 which normally is meant to indicate that GCMP has not yet been mmapped. This non-zero value is now interpreted as GCMP being present resulting in a write attempt to a GCMP register resulting in a crash. Reported and a build fix on top of my fix by Rob Landley .

cpumask: arch_send_call_function_ipi_mask: mips

2009-09-24T00:04:45+00:00

We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(), and by defining it, the old arch_send_call_function_ipi is defined by the core code. We also take the chance to wean the implementations off the obsolescent for_each_cpu_mask(): making send_ipi_mask take the pointer seemed the most natural way to ensure all implementations used for_each_cpu.

MIPS: Add arch generic CPU hotplug

2009-06-24T17:34:40+00:00

Each platform has to add support for CPU hotplugging itself by providing suitable definitions for the cpu_disable and cpu_die of the smp_ops methods and setting SYS_SUPPORTS_HOTPLUG_CPU. A platform should only set SYS_SUPPORTS_HOTPLUG_CPU once all it's smp_ops definitions have the necessary changes. This patch contains the changes to the dummy smp_ops definition for uni-processor systems. Parts of the code contributed by Cavium Inc. Signed-off-by: Ralf Baechle
