laptops and mobile devices offer features like instant-on and swift resume from sleep mode, ensuring a seamless and responsive user experience. this technology enhances portability, making your device an efficient companion on the go. how does acpi handle system sleep states, and what are their im...
There's a short series of error messages that occurs when there's no driver registered to handle an ACPI region that was called. In this example, we can see that it was the power_meter driver which caused the access to the IPMI region from the end of the "ACPI Exception" line. ...
驱动加载probe()函数,同检测ACPI_HANDLE或者of_node, 详细参见驱动实现章节。 设备枚举 Device descriptions in ACPI should use standard recognized ACPI interfaces. These may contain less information than is typically provided via a Device Tree description for the same device. This is also one of the re...
數據:包含裝置 PEPHANDLE 之PEP_ACPI_UNREGISTER_DEVICE結構的指標。從PEP 取消 ACPI 服務的指定裝置註冊。為了回應此通知,PEP 可以在先前的PEP_NOTIFY_ACPI_REGISTER_DEVICE通知中終結 PEP 為這個裝置建立的 PEPHANDLE。若要傳送PEP_NOTIFY_ACPI_UNREGISTER_DEVICE通知,PoFx 會呼叫 PEP 的 AcceptAcpiNotification 回呼...
データ:デバイスの PEPHANDLE を含むPEP_ACPI_UNREGISTER_DEVICE構造へのポインター。 PEP から ACPI サービスの指定したデバイスの登録を取り消します。 この通知に応答して、PEP は前のPEP_NOTIFY_ACPI_REGISTER_DEVICE通知でこのデバイス用に作成された PEPHANDLE を破棄できます。 PEP_NOTIFY_ACP...
Note this is not#455, since the first line doesn’t appear in this case. This issue has often been seen as an issue with ACPI, either with the acpi-handle-hack in bbswitch and the corresponding issue upstream. I think next step is to try with nouveau. ...
SwContext.SwSmiInputValue = (UINTN) PcdGet8 (PcdAcpiEnableSwSmi);Status = SwDispatch->Register (SwDispatch,EnableAcpiCallback,&SwContext,&SwHandle); 同理,Bios为了支持windows开启ACPI,也会以同样的方式注册SMI处理函数。对于VMware,它注册的值...
PEP_ACPI_EVALUATE_CONTROL_METHOD 结构指定要计算的 ACPI 控制方法、要提供给此方法的输入参数,以及计算结果的输出缓冲区。语法C++ 复制 typedef struct _PEP_ACPI_EVALUATE_CONTROL_METHOD { PEPHANDLE DeviceHandle; ULONG RequestFlags; union { ULONG MethodName; ANSI_STRING MethodNameString; };...
