* arch/hotplug: Call into idle with a proper stateThomas Gleixner2016-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Let the non boot cpus call into idle with the corresponding hotplug state, so the hotplug core can handle the further bringup. That's a first step to convert the boot side of the hotplugged cpus to do all the synchronization with the other side through the state machine. For now it'll only start the hotplug thread and kick the full bringup of the cpu.

* sparc: delete __cpuinit/__CPUINIT usage from all usersPaul Gortmaker2013-07-151-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/sparc uses of the __cpuinit macros from C files and removes __CPUINIT from assembly files. Note that even though arch/sparc/kernel/trampoline_64.S has instances of ".previous" in it, they are all paired off against explicit ".section" directives, and not implicitly paired with __CPUINIT (unlike mips and arm were).

* | sparc32: generic clockevent supportTkhai Kirill2012-04-151-20/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel uses l14 timers as clockevents. l10 timer is used as clocksource if platform master_l10_counter isn't constantly zero. The clocksource is continuous, so it's possible to use high resolution timers. l10 timer is also used as clockevent on UP configurations. This realization is for sun4m, sun4d, sun4c, microsparc-IIep and LEON platforms. The appropriate LEON changes was made by Konrad Eisele. In case of sun4m's oneshot mode, profile irq is zeroed in smp4m_percpu_timer_interrupt(). It is maybe needless (double, triple etc overflow does nothing). sun4d is able to have oneshot mode too, but I haven't any way to test it. So code of its percpu timer handler is made as much equal to the current code as possible. The patch is tested on sun4m box in SMP mode by me, and tested by Konrad on leon in up mode (leon smp is broken atm - due to other reasons).

The sun4m has 15 soft-IRQs and three of them is used with this patch, the three IPIs was previously implemented with the cross-call IRQ15 which does not work with locking routines such as spinlocks because IRQ15 is NMI, it may cause deadlock. The IRQ trap handler code assumes (in the same spritit as the old it seems) that hard interrupts will be generated until handled (level), when a IRQ happens the IRQ pending register is checked for pending soft-IRQs. When both hard and soft IRQ happens at the same time only soft-IRQs are handled. The old code implemented a soft-IRQ traphandler at IRQ14 which called smp_reschedule_irq which in turn called set_need_resched. It seems to be an old relic and is replaced with the interrupt traphander exit code RESTORE_ALL, it calls schedule() when appropriate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current sparc32 SMP IPI generation is implemented the cross call function. The cross call function uses IRQ15 the NMI, this is has the effect that IPIs will interrupt IRQ critical areas and hang the system. Typically on/after spin_lock_irqsave calls can be aborted. The cross call functionality must still exist to flush cache/TLBS. This patch provides CPU models a custom way to implement generation of IPIs on the generic code's request. The typical approach is to generate an IRQ for each IPI case. After this patch each sparc32 SMP CPU model needs to implement IPIs in order to function properly.

* sparc: prepare kernel/ for unificationSam Ravnborg2008-12-041-0/+423
o sparc32 files with identical names to sparc64 renamed to <name>_32.S o introduced a few Kconfig helpers to simplify Makefile logic o refactored Makefile to prepare for unification - use obj-$(CONFIG_SPARC32) for sparc32 specific files - use <name>_$(BITS) for files where sparc64 has a _64 variant - sparc64 directly include a few files where sparc32 builds them, refer to these files directly (no BITS) - sneaked in -Werror as used by sparc64 o modified sparc/Makefile to use the new names for head/init_task Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.
