Cool (: I currently only have a small optimization fix for the MX interrupt controller, otherwise I think it's good. Should I send a follow-up patch or respin the whole series? > On 10/16/13, 3:42 PM, Max Filippov wrote: >> >> Hi Chris, >> >> this series adds SMP support for xtensa. >> There's a number of trivial cleanups: >> xtensa: remove NO_IRQ definitions >> xtensa: fix build warning in 64-bit build environment >> xtensa: fix build warning from gcc-4.7.2 >> xtensa: call check_s32c1i after trap_init >> xtensa: move init_mmu declaration to mmu_context.h >> >> a couple of fixes for spinlocks: >> xtensa: fix arch spinlock function names >> xtensa: fix __delay for small loop count >> >> three fixes for the clocksources, with these we get high precision timers >> usable in SMP and IRQ time accounting: >> xtensa: mark ccount as continuous clocksource >> xtensa: update clockevent setup for SMP >> xtensa: enable HAVE_IRQ_TIME_ACCOUNTING >> >> fixes and rearrangement of IRQ handling code and a new driver for MX >> interrupt distributor: >> xtensa: move built-in PIC to drivers/irqchip >> xtensa: clean up do_interrupt/do_IRQ >> xtensa: clear timer IRQ unconditionally in its handler >> xtensa: add MX irqchip >> >> and finally SMP and hotplug CPU support and a sample SMP-capable CPU >> variant: >> xtensa: add SMP support >> xtensa: implement CPU hotplug >> xtensa: add Three Core HiFi-2 MX Variant. >> >> Please review. >> >> You can pull these changes from my git tree, >> the following changes since commit >> 61e6cfa80de5760bbe406f4e815b7739205754d2: >> >> Linux 3.12-rc5 (2013-10-13 15:41:28 -0700) >> >> are available in the git repository at: >> >> git://github.com/jcmvbkbc/linux-xtensa.git tags/xtensa-smp-20131017 >> >> for you to fetch changes up to 4862c5ae570b8a40275f413dfa2e3f184ecfa1d9: >> >> xtensa: implement CPU hotplug (2013-10-17 01:50:17 +0400) >> >> ---------------------------------------------------------------- >> Clean up minor warnings. >> Fix spinlock function names, provide missing definitions. >> Extract PIC into drivers/irqchip. >> Clean up IRQ handling. >> Add MX interrupt distributor. >> Add SMP support. >> Add hotplug CPU support. >> Add SMP-capable core variant. >> >> ---------------------------------------------------------------- >> Baruch Siach (1): >> xtensa: mark ccount as continuous clocksource >> >> Max Filippov (15): >> xtensa: remove NO_IRQ definitions >> xtensa: fix build warning in 64-bit build environment >> xtensa: fix build warning from gcc-4.7.2 >> xtensa: fix arch spinlock function names >> xtensa: fix __delay for small loop count >> xtensa: enable HAVE_IRQ_TIME_ACCOUNTING >> xtensa: update clockevent setup for SMP >> xtensa: call check_s32c1i after trap_init >> xtensa: move init_mmu declaration to mmu_context.h >> xtensa: move built-in PIC to drivers/irqchip >> xtensa: clean up do_interrupt/do_IRQ >> xtensa: clear timer IRQ unconditionally in its handler >> xtensa: add MX irqchip >> xtensa: add SMP support >> xtensa: implement CPU hotplug >> >> Piet Delaney (1): >> xtensa: add Three Core HiFi-2 MX Variant. >> >> arch/xtensa/Kconfig | 54 +- >> arch/xtensa/Makefile | 1 + >> arch/xtensa/include/asm/barrier.h | 4 +- >> arch/xtensa/include/asm/bitops.h | 8 +- >> arch/xtensa/include/asm/cacheflush.h | 40 +- >> arch/xtensa/include/asm/delay.h | 9 +- >> arch/xtensa/include/asm/irq.h | 9 + >> arch/xtensa/include/asm/mmu.h | 10 +- >> arch/xtensa/include/asm/mmu_context.h | 106 ++-- >> arch/xtensa/include/asm/mxregs.h | 46 ++ >> arch/xtensa/include/asm/processor.h | 20 + >> arch/xtensa/include/asm/ptrace.h | 8 + >> arch/xtensa/include/asm/smp.h | 38 +- >> arch/xtensa/include/asm/spinlock.h | 31 +- >> arch/xtensa/include/asm/spinlock_types.h | 20 + >> arch/xtensa/include/asm/timex.h | 14 +- >> arch/xtensa/include/asm/tlbflush.h | 42 +- >> arch/xtensa/include/asm/traps.h | 1 + >> arch/xtensa/include/asm/vectors.h | 4 + >> arch/xtensa/kernel/Makefile | 1 + >> arch/xtensa/kernel/head.S | 181 +++++-- >> arch/xtensa/kernel/irq.c | 207 ++++---- >> arch/xtensa/kernel/mxhead.S | 85 +++ >> arch/xtensa/kernel/setup.c | 92 ++-- >> arch/xtensa/kernel/smp.c | 591 >> +++++++++++++++++++++ >> arch/xtensa/kernel/time.c | 56 +- >> arch/xtensa/kernel/traps.c | 56 +- >> arch/xtensa/kernel/vmlinux.lds.S | 26 + >> arch/xtensa/mm/cache.c | 7 +- >> arch/xtensa/mm/fault.c | 2 +- >> arch/xtensa/mm/misc.S | 4 +- >> arch/xtensa/mm/mmu.c | 4 +- >> arch/xtensa/mm/tlb.c | 37 +- >> .../platforms/xtfpga/include/platform/hardware.h | 6 +- >> arch/xtensa/variants/s6000/include/variant/irq.h | 1 -
