| |
I'm merging the per-cpu arrays (local_bh_count, local_irq_count,...) into a cache-line aligned per-cpu array, but I'm stuck in arch/i386/kernel/smpboot.c:
/* * Scan the memory blocks for an SMP configuration block. */ static int __init smp_get_mpf(struct intel_mp_floating *mpf) { [...] if (mpf->mpf_feature1 > 4) { printk("Bus #1 is PCI\n");
/* * Set local APIC version to the integrated form. * It's initialized to zero otherwise, representing * a discrete 82489DX. */ apic_version[0] = 0x10; apic_version[1] = 0x10; } [...] } why only apic_version[{0,1}]? Can I replace it with this line, or will it break on some hardware? for(i=0;i<NR_CPUS;i++) cpu_data[i].apic_version=0x10;
AFAICS, the function is called before the secondary cpu's are started, and the apic_version is overwritten later.
Thanks, Manfred
