[Xen-devel] Xen support for i386/core and i386/core2?

[Markus Armbruster <armbru@xxxxxxxxxx>]

Xen's oprofile code is derived from Linux.  Linux's version knows
core, Xen's doesn't.

Linux code (arch/i386/oprofile/nmi_int.c):

static int __init ppro_init(char ** cpu_type)
{
        __u8 cpu_model = boot_cpu_data.x86_model;

        if (cpu_model == 14)
                *cpu_type = "i386/core";
        else if (cpu_model == 15)
                *cpu_type = "i386/core_2";
        else if (cpu_model > 0xd)
                return 0;
        else if (cpu_model == 9) {
                *cpu_type = "i386/p6_mobile";
        } else if (cpu_model > 5) {
                *cpu_type = "i386/piii";
        } else if (cpu_model > 2) {
                *cpu_type = "i386/pii";
        } else {
                *cpu_type = "i386/ppro";
        }

        model = &op_ppro_spec;
        return 1;
}

Current Xen code:

static int __init ppro_init(char *cpu_type)
{
        __u8 cpu_model = current_cpu_data.x86_model;

        if (cpu_model > 0xd) {
                printk("xenoprof: Initialization failed. "
                       "Intel processor model %d for P6 class family is not "
                       "supported\n", cpu_model);
                return 0;
        }

        if (cpu_model == 9) {
                strncpy (cpu_type, "i386/p6_mobile", XENOPROF_CPU_TYPE_SIZE - 
1);
        } else if (cpu_model > 5) {
                strncpy (cpu_type, "i386/piii", XENOPROF_CPU_TYPE_SIZE - 1);
        } else if (cpu_model > 2) {
                strncpy (cpu_type, "i386/pii", XENOPROF_CPU_TYPE_SIZE - 1);
        } else {
                strncpy (cpu_type, "i386/ppro", XENOPROF_CPU_TYPE_SIZE - 1);
        }

        model = &op_ppro_spec;
        return 1;
}

Andrew Theurer posted a patch back in October[*], which makes the Xen
code match the Linux code.  What happened to it?
