Arc processors may have DSP extension which is optional. In this patch series we: * Handle issues caused by DSP extension presence in HW * Add optional support for DSP-enabled applications in userspace (with optional AGU extension support) * Do minor cleanups Eugeniy Paltsev (5): ARC: pt_regs: remove hardcoded registers offset ARC: add helpers to sanitize config options ARC: handle DSP presence in HW ARC: add support for DSP-enabled userspace applications ARC: allow userspace DSP applications to use AGU extensions arch/arc/Kconfig | 39 +++++++- arch/arc/include/asm/arcregs.h | 26 ++++++ arch/arc/include/asm/dsp-impl.h | 141 +++++++++++++++++++++++++++++ arch/arc/include/asm/dsp.h | 50 ++++++++++ arch/arc/include/asm/entry-arcv2.h | 14 ++- arch/arc/include/asm/processor.h | 4 + arch/arc/include/asm/ptrace.h | 4 + arch/arc/include/asm/switch_to.h | 2 + arch/arc/kernel/asm-offsets.c | 16 ++++ arch/arc/kernel/head.S | 4 + arch/arc/kernel/setup.c | 47 +++++++--- 11 files changed, 329 insertions(+), 18 deletions(-) create mode 100644 arch/arc/include/asm/dsp-impl.h create mode 100644 arch/arc/include/asm/dsp.h -- 2.21.0 _______________________________________________ linux-snps-arc mailing list linux-snps-arc@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/linux-snps-arc
