函数名称：While checking the dmi string information, just checking the product* serial key should be enough, as this will always have a VMware* specific string when running under VMware hypervisor.* If !boot_cpu_has(X86_FEATURE_HYPERVISOR), vmware_hypercall_mode

函数原型：static uint32_t __init vmware_platform(void)

返回类型：uint32_t

参数：无

234  如果boot_cpu_has(Running on a hypervisor )则
238  cpuid(CPUID_VMWARE_INFO_LEAF, & eax, & hyper_vendor_id[0], & hyper_vendor_id[1], & hyper_vendor_id[2])
240  如果非内存比较则
241  如果eax大于等于CPUID_VMWARE_FEATURES_LEAF则vmware_hypercall_mode等于vmware_select_hypercall()
245  打印信息("hypercall mode: 0x%02x\n", (unsignedint)vmware_hypercall_mode)
248  返回:CPUID_VMWARE_INFO_LEAF
250  否则如果dmi_available且dmi_name_in_serial("VMware")且__vmware_platform()则返回:1
254  返回:0
