Hi Gaurav, Thank you for the patch! Yet something to improve: [auto build test ERROR on tip/irq/core] [also build test ERROR on v5.5-rc1 next-20191209] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Gaurav-Kohli/irqchip-gic-v3-Avoid-check-of-lpi-configuration-for-non-existent-cpu/20191207-092729 base: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git 407e62f52aadd8124dcba407f18a03aedce9b86a config: arm-multi_v7_defconfig (attached as .config) compiler: arm-linux-gnueabi-gcc (GCC) 7.5.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree GCC_VERSION=7.5.0 make.cross ARCH=arm If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All errors (new ones prefixed by >>): drivers//irqchip/irq-gic-v3.c: In function 'gic_iterate_rdists': >> drivers//irqchip/irq-gic-v3.c:801:30: error: 'INVALID_HWID' undeclared (first use in this function); did you mean 'INVALID_HWIRQ'? cpu_logical_map(cpu) != INVALID_HWID); ^~~~~~~~~~~~ INVALID_HWIRQ drivers//irqchip/irq-gic-v3.c:801:30: note: each undeclared identifier is reported only once for each function it appears in vim +801 drivers//irqchip/irq-gic-v3.c 764 765 static int gic_iterate_rdists(int (*fn)(struct redist_region *, void __iomem *)) 766 { 767 int ret = -ENODEV; 768 int i; 769 int cpu = 0; 770 771 for (i = 0; i < gic_data.nr_redist_regions; i++) { 772 void __iomem *ptr = gic_data.redist_regions[i].redist_base; 773 u64 typer; 774 u32 reg; 775 776 reg = readl_relaxed(ptr + GICR_PIDR2) & GIC_PIDR2_ARCH_MASK; 777 if (reg != GIC_PIDR2_ARCH_GICv3 && 778 reg != GIC_PIDR2_ARCH_GICv4) { /* We're in trouble... */ 779 pr_warn("No redistributor present @%p\n", ptr); 780 break; 781 } 782 783 do { 784 cpu++; 785 typer = gic_read_typer(ptr + GICR_TYPER); 786 ret = fn(gic_data.redist_regions + i, ptr); 787 if (!ret) 788 return 0; 789 790 if (gic_data.redist_regions[i].single_redist) 791 break; 792 793 if (gic_data.redist_stride) { 794 ptr += gic_data.redist_stride; 795 } else { 796 ptr += SZ_64K * 2; /* Skip RD_base + SGI_base */ 797 if (typer & GICR_TYPER_VLPIS) 798 ptr += SZ_64K * 2; /* Skip VLPI_base + reserved page */ 799 } 800 } while (!(typer & GICR_TYPER_LAST) && > 801 cpu_logical_map(cpu) != INVALID_HWID); 802 } 803 804 return ret ? -ENODEV : 0; 805 } 806 --- 0-DAY kernel test infrastructure Open Source Technology Center https://lists.01.org/hyperkitty/list/kbuild-all@xxxxxxxxxxxx Intel Corporation
