void * | _cx |
111 | cstate_type等于address右移MWAIT_SUBSTATE_SIZE位按位与MWAIT_CSTATE_MASK的值加1 |
116 | retval等于0 |
118 | 如果num_cstate_subtype恒等于0则 |
119 | 打印警告信息(FW_BUG* Add this to a message where you are sure the firmware is buggy or behaves* really stupid or out of spec"ACPI MWAIT C-state 0x%x not supported by HW (0x%x)\n", address, edx_part) |
121 | retval等于负1 |
