ACRN CPUID位域
|

==============
|
||||
|
||||
在ACRN超级管理器上运行的客户虚拟机可以使用CPUID检查其一些功能。
|
||||
|
||||
ACRN的cpuid函数是:
|
||||
|
||||
函数: 0x40000000
|
||||
|
||||
返回::
|
||||
|
||||
eax = 0x40000010
|
||||
ebx = 0x4e524341
|
||||
ecx = 0x4e524341
|
||||
edx = 0x4e524341
|
||||
|
||||
注意,ebx,ecx和edx中的这个值对应于字符串“ACRNACRNACRN”。eax中的值对应于这个叶子
|
||||
中存在的最大cpuid函数,如果将来有更多的函数加入,将被更新。
|
||||
|
||||
函数: define ACRN_CPUID_FEATURES (0x40000001)
|
||||
|
||||
返回::
|
||||
|
||||
ebx, ecx, edx
|
||||
eax = an OR'ed group of (1 << flag)
|
||||
|
||||
其中 ``flag`` 的定义如下:
