Used for percpu variable updates. Local atomic operations only guarantee variable modification atomicity wrt the CPU which owns the data and these needs to be executed in a preemption safe way. Here is the design of this patch. Since local_* operations are only need to be atomic to interrupts (IIUC), we have two options. Either replay the "op" if interrupted or replay the interrupt after the "op". Initial patchset posted was based on implementing local_* operation based on CR5 which replay's the "op". Patchset had issues in case of rewinding the address pointor from an array. This make the slow path really slow. Since CR5 based implementation proposed using __ex_table to find the rewind addressr, this rasied concerns about size of __ex_table and vmlinux. https://lists.ozlabs.org/pipermail/linuxppc-dev/2014-December/123115.html But this patch uses, powerpc_local_irq_pmu_save to soft_disable interrupts (including PMIs). After finishing the "op", powerpc_local_irq_pmu_restore() called and correspondingly interrupts are replayed if any occured. patch re-write the current local_* functions to use arch_local_irq_disbale. Base flow for each function is { powerpc_local_irq_pmu_save(flags) load .. store powerpc_local_irq_pmu_restore(flags) } Reason for the approach is that, currently l[w/d]arx/st[w/d]cx. instruction pair is used for local_* operations, which are heavy on cycle count and they dont support a local variant. So to see whether the new implementation helps, used a modified version of Rusty's benchmark code on local_t. https://lkml.org/lkml/2008/12/16/450 Modifications to Rusty's benchmark code: - Executed only local_t test Here are the values with the patch. Time in ns per iteration Local_t Without Patch With Patch _inc 38 10 _add 38 10 _read 4 4 _add_return 38 10 Currently only asm/local.h has been rewritten, and also the entire change is tested only in PPC64 (pseries guest) and PPC64 host (LE) Patch convert the inline asm implementation of the local_t to C. Also removed the local_dec_if_positive since there are no users for this.
