An embodiment of the present invention provides an apparatus starting method, which is shown in fig. 1 and includes the following steps:
step 101, acquiring target data corresponding to a hardware device from a first memory of the electronic device based on a starting instruction for starting the hardware device of the electronic device.
Wherein the first memory has a nonvolatile storage function; the target data includes one or more of: start-up data, setting information and drive data.
In other embodiments of the present invention, the step 101 may be implemented by the electronic device, based on a start instruction for starting a hardware device of the electronic device, to acquire target data corresponding to the hardware device from a first memory of the electronic device; the electronic device may be an electronic device capable of installing an operating system or application software. In practical applications, the electronic device is preferably any type of server device. In the above scheme, the hardware device is a generic term referring to various physical devices composed of electronic, mechanical, and optoelectronic components in a computer system; the hardware equipment comprises equipment such as a CPU, a hard disk, a display card and the like.
In other embodiments of the present invention, the first memory has a nonvolatile function; it is understood that the first memory can still store the data of the internal memory after the electronic device is powered off, and the stored content of the first memory does not change according to the external environment. Preferably, the first memory further has a high-speed read-write characteristic, and the delay time of the first memory is in the order of nanoseconds, so that the time for starting the hardware device of the electronic device can be effectively shortened. In addition, the startup data in the above scheme refers to a program required to start up hardware devices in the electronic device, such as a program for initializing internal resources of the CPU and a program for initializing external hardware devices; the setting information may refer to hardware configuration data of the current system, for example, the setting information is to initialize a hard disk in the order from D disk to C disk to E disk; the drive data means a special program that can cause the CPU to communicate with an external device; it is understood to be a hardware interface through which the operating system can control the operation of the hardware device.
In other embodiments of the present invention, before performing step 101, the operation mode of the first memory needs to be set to the preset operation mode. The preset working mode is a mode with persistent storage. It should be noted that the first memory has multiple operation modes, and can perform different storage functions.
And 102, starting the hardware equipment of the electronic equipment based on the target data.
Wherein step 102 is implemented by an electronic device, based on the target data, the hardware device that starts the electronic device. Here, the electronic apparatus executes the startup data and the drive data in accordance with the setting information after acquiring the target data.
The device starting method provided by the embodiment of the invention comprises the steps of firstly, acquiring target data corresponding to hardware equipment from a first memory of the electronic equipment based on a starting instruction for starting the hardware equipment of the electronic equipment; wherein the first memory has a non-volatile storage function; the target data includes one or more of: start data, setting information and drive data; starting the hardware device of the electronic device based on the target data. Therefore, the target data is stored in the first memory with the nonvolatile function, and when the electronic equipment is restarted, the target data is directly taken out of the first memory, so that the problem that the target data needs to be copied from the ROM once when the electronic equipment is restarted in the prior art is solved, the time consumed by starting is reduced, and the working efficiency of the electronic equipment is improved.
Based on the foregoing embodiment, the present invention further provides an apparatus starting method, which, as shown in fig. 2, includes the following steps:
step 201, the electronic device acquires target data corresponding to a hardware device from a first memory of the electronic device based on a start instruction for starting the hardware device of the electronic device.
Wherein the first memory has a non-volatile storage function; the target data includes one or more of: start-up data, setting information and drive data.
In other embodiments of the present invention, the first memory is preferably an Apache channel (AEP) device. Here, the AEP device is a storage device having non-volatility and high-speed read-write characteristics; it is understood that the data stored internally by the AEP device is not lost after power is removed. All data required for starting the hardware device, including start data, setting information, drive data, and the like, can be stored in the AEP device.
Step 202, if the target data is not stored in the first memory, the electronic device obtains the start data and the driving data from the second memory, and stores the start data and the driving data in the first memory.
Wherein the second memory does not have a non-volatile storage function.
In other embodiments of the present invention, the second Memory may be a Read-Only Memory (ROM); the data stored in the ROM is pre-stored data, and the data cannot be changed or deleted once being stored in the ROM; therefore, the ROM usually stores data unique to the electronic device, such as startup data, drive data, and the like. Since the ROM cannot be rewritten, the electronic device needs to copy boot data and drive data from the ROM into a Random Access Memory (RAM) for reading and writing and executing at the time of booting. However, the RAM loses its stored contents when the electronic device is powered off, and therefore, the electronic device needs to copy the boot data and the driving data every time the electronic device is booted, which reduces the booting speed of the electronic device.
In this embodiment, when the electronic device is started, first, target data is acquired from the first memory; if the first memory stores the target data, directly acquiring the target data from the first memory for execution; if the electronic device detects that the target data is not stored in the first storage, the electronic device needs to copy the starting data and the driving data in the target data from the ROM to the first storage for execution. It is worth noting that the electronic device copies the starting data and the driving data from the second memory to the first memory for execution, and the first memory can store the starting data and the driving data, so that the electronic device can directly read the starting data and the driving data from the first memory in the subsequent starting process, and the starting speed is improved.
And step 203, the electronic equipment acquires the setting information from the third memory and stores the setting information in the first memory.
In other embodiments of the present invention, the third memory may be a Complementary Metal Oxide Semiconductor (COMS) memory; in another embodiment, the third Memory may also be a Non-Volatile Random Access Memory (NVRAM). In practical applications, the third memory is generally used to store the hardware configuration data of the current system, i.e. the setting information mentioned above.
In this embodiment, the electronic device first obtains the setting information from the first memory each time the electronic device is started, and if the setting information exists in the first memory, the electronic device directly reads the setting information, and if the setting information is not stored in the first memory, the electronic device copies the setting information from the third memory to the first memory. It is worth noting that the first memory can store the setting information while the electronic device copies the setting information from the third memory to the first memory for execution, so that the electronic device can directly read the setting information from the first memory in the subsequent starting process, and the starting speed is improved.
Step 204, the electronic device obtains the starting data, the setting information and the driving data from the first memory.
Specifically, after steps 202 and 203 are executed, the first memory stores therein start-up data, setting information, and driving data; the electronic equipment only needs to acquire the starting data, the setting information and the driving data from the first memory; in this way, the electronic device only needs to copy the starting data and the driving data from the second memory to the first memory and copy the setting information from the third memory to the first memory at the time of initial starting; therefore, the electronic equipment only needs to directly read the target data from the first equipment in each subsequent starting, and the hardware starting speed of the electronic equipment can be effectively improved.
Step 205, the electronic device starts the hardware device of the electronic device based on the start data, the setting information and the driving data.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
The device starting method provided by the embodiment of the invention comprises the steps of firstly, acquiring target data corresponding to hardware equipment from a first memory of the electronic equipment based on a starting instruction for starting the hardware equipment of the electronic equipment; wherein the first memory has a non-volatile storage function; the target data includes one or more of: start data, setting information and drive data; starting the hardware device of the electronic device based on the target data. Therefore, the target data is stored in the first memory with the nonvolatile function, and when the electronic equipment is restarted, the target data is directly taken out of the first memory, so that the problem that the target data needs to be copied from the ROM once when the electronic equipment is restarted in the prior art is solved, the time consumed by starting is reduced, and the working efficiency of the electronic equipment is improved.
Based on the foregoing embodiments, an embodiment of the present invention provides an apparatus starting method, which is shown in fig. 3 and includes the following steps:
step 301, the electronic device obtains target data corresponding to the hardware device from a first memory of the electronic device based on a start instruction for starting the hardware device of the electronic device.
Step 302, if the target data is not stored in the first memory, the electronic device obtains the start data and the driving data from the second memory, and stores the start data in the first memory and the fourth memory.
Wherein the fourth memory is different from the first and second memories.
In other embodiments of the present invention, the fourth memory may be a RAM; here, if the electronic device detects that the target data is not stored in the first memory, the electronic device may directly copy the boot data and the driving data stored in the second memory (i.e., ROM) to the fourth memory (i.e., RAM) for execution; in the process of copying the start data and the drive data to the fourth memory, the electronic device simultaneously copies the data to the first memory. It is understood that, in the case that the hardware device is started for the first time or the target data is not stored in the first memory, the electronic device copies the target data from the ROM into the RAM to start the hardware device, and simultaneously copies the target data into the AEP device to store the target data.
Step 303, the electronic device obtains the setting information from a third memory, and stores the setting information in the first memory and the fourth memory.
Wherein the fourth memory is different from the third memory; the second memory and the fourth memory do not have a nonvolatile storage function.
In other embodiments of the present invention, the electronic device obtains the setting information from a third memory, and saves the setting information to the first memory and the fourth memory; it is understood that the electronic device copies the setting information from the cmos chip to the RAM for execution, and at the same time, copies the setting information to the AEP.
Step 304, the electronic device obtains the startup data, the setting information and the driving data from the fourth memory.
Specifically, after the electronic device goes through steps 302 and 303, the first memory and the fourth memory already store target data required for starting the hardware device; therefore, when the hardware equipment is started next time, the electronic equipment does not need the process of copying the target data from the ROM, but the electronic equipment directly reads the corresponding data from the AEP and directly executes the corresponding data.
And 305, starting the hardware equipment of the electronic equipment by the electronic equipment based on the target data.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
The device starting method provided by the embodiment of the invention comprises the steps of firstly, acquiring target data corresponding to hardware equipment from a first memory of the electronic equipment based on a starting instruction for starting the hardware equipment of the electronic equipment; wherein the first memory has a non-volatile storage function; the target data includes one or more of: start data, setting information and drive data; starting the hardware device of the electronic device based on the target data. Therefore, the target data is stored in the first memory with the nonvolatile function, and when the electronic equipment is restarted, the target data is directly taken out of the first memory, so that the problem that the target data needs to be copied from the ROM once when the electronic equipment is restarted in the prior art is solved, the time consumed by starting is reduced, and the working efficiency of the electronic equipment is improved.
Based on the foregoing embodiments, an embodiment of the present invention provides an apparatus starting method, which is shown in fig. 4 and includes the following steps:
step 401, the electronic device obtains, based on a start instruction for starting a hardware device of the electronic device, start data and setting information in target data from a first memory at a first stage in a Unified Extensible Firmware Interface (UEFI) start process.
Wherein the first phase is used to indicate the initialization phase of UEFI.
In other embodiments of the present invention, the hardware device comprises a unified extensible firmware interface, UEFI; the hardware starting process is the UEFI starting process. Generally, as shown in fig. 5, the UEFI start-up process has seven stages, including: a Security Phase (SEC) Phase, a Pre-EFI initialization (PEI) Phase, a Driver Execution Environment (DXE) Phase, a Boot Device Selection (BDS) Phase, an operating System Load (TSL) Phase, a Run Time (Run Time) Phase, and an disaster recovery (After Life) Phase.
In other embodiments of the present invention, the first phase in step 401 is referred to as the PEI phase of the UEFI startup process; here, the phase prepares an execution environment for the DXE phase, composes a handover Block (HOB) list of information to be passed to the DXE phase, and finally passes control to the DXE phase. Functionally, PEI can be divided into two parts: the PEI kernel is responsible for PEI basic services and processes; the PEIM dispatcher finds out all PEIMs in the system.
The PEI execution flow is shown in FIG. 6 and includes PEI entry, initializing PEI Core Service (Core Service), scheduling PEI Modules (PEI Modules, PEIMs) in the system, preparing HOB lists, and entering DXE entry. In the PEI module stage of the dispatching system, the electronic equipment can also complete the initialization of the relevant functions of the CPU PEIM, the initialization of the relevant functions of the PEIM platform and the initialization of the memory; the memory initialization includes initialization of a normal RAM.
In this embodiment, after normal RAM initialization, first memory (i.e., AEP device) initialization is performed. Specifically, the electronic device first detects whether the persistent storage area of the AEP has boot data and configuration information stored therein. When the persistent storage area of the AEP has the above-mentioned startup data and setting information, the startup data and setting information are acquired from the AEP.
Additionally, prior to performing step 401, the operational mode of at least one AEP may be set to a mode with persistent storage, such as an App Direct (App Direct) mode.
And step 402, the electronic device acquires the driving data in the target data from the first memory at a second stage in the UEFI starting process.
Wherein the second phase is used for indicating a drive data loading phase of the UEFI; the second stage is performed after the first stage.
Here, the second phase in step 402 refers to the DXE phase of the UEFI boot process. The DXE phase performs most of the system initialization work, and this phase can perform a lot of complex work. The execution flow is shown in fig. 7, and includes: DXE entry, initializing system services according to HOB list, scheduling drivers (drivers) in the system, and entry into BDS entry. The drivers in the scheduling system include all drivers in the traversal firmware, when the resources on which the drivers depend are all satisfied, whether the first memory (i.e., the AEP device) stores the driving data is determined, and when the AEP device stores the driving data, the driving data is directly read from the AEP.
In step 403, the electronic device starts the hardware device of the electronic device based on the start data, the setting information and the driving data.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
In the scheme, the electronic equipment can directly read the data required by UEFI starting in the AEP equipment, reduce the copying times of target data and further improve the UEFI initialization speed; UEFI initialization speed is improved by directly reading UEFI setting information from AEP; and the UEFI initialization speed is improved by reducing the initialization operation of the peripheral.
Based on the foregoing embodiments, an embodiment of the present invention provides an apparatus starting method, as shown in fig. 8, the method includes the following steps:
step 801, the electronic device judges whether target data is stored in the first memory at a first stage in the UEFI starting process based on a starting instruction for starting a hardware device of the electronic device.
And step 802, if the target data is not stored in the first memory, the electronic device acquires the starting data from the second memory at a first stage in the UEFI starting process, and stores the starting data in the first memory.
Specifically, as shown in fig. 6, in the AEP initialization process in the PEI phase, when it is determined that the persistent storage area of the AEP device does not store the setting information and the start data, the electronic device opens up a space in the persistent storage area of the AEP device, and can acquire the start data from the second memory (i.e., ROM) and store the start data into the space opened up by the AEP.
In other embodiments of the present invention, step 802 may further be: and at the first stage in the UEFI starting process, acquiring the starting data from the second memory and storing the starting data into the first memory and the fourth memory.
Specifically, the fourth memory is a RAM. When the electronic device detects that target data is not stored in the AEP in the initialization process of the AEP in the PEI phase, the electronic device can copy starting data in the ROM and simultaneously store the starting data in the RAM and the AEP.
And step 803, the electronic device acquires the setting information from the third memory and stores the setting information in the first memory.
Here, based on the above steps, in the AEP initialization process in the PEI phase, when it is determined that the persistent storage area of the AEP device does not store the setting information and the start-up data, the electronic device may acquire the setting information from the third memory (i.e., COMS or NVRAM) and copy the setting information into the AEP persistent storage area.
In other embodiments of the present invention, step 803 may also be: and acquiring the setting information from the third memory, and saving the setting information to the first memory and the fourth memory.
Specifically, in the AEP initialization process in the PEI phase, when detecting that the setting information is not saved in the AEP, the electronic device may copy the setting information in the COMS and save the setting information in the RAM and the AEP at the same time.
And step 804, the electronic device acquires the driving data from the second memory at a second stage in the UEFI starting process, and stores the driving data in the first memory.
Specifically, as shown in fig. 7, in the process of detecting whether the drive data exists in the DXE phase, when it is determined that the persistent storage area of the AEP device does not store the drive data, the electronic device creates a space in the persistent storage area of the AEP device, acquires the drive data from the second memory (i.e., ROM), and stores the drive data in the persistent storage area of the AEP device.
In addition, step 804 may further be: and at the second stage in the UEFI starting process, acquiring the driving data from the second memory and storing the driving data into the first memory and the fourth memory.
Specifically, in the process of detecting whether the drive data exists in the DXE phase, when detecting that the drive data is not saved in the AEP, the electronic device may copy the drive data in the ROM and save the drive data in the RAM and the AEP at the same time.
Step 805, the electronic device obtains the startup data, the setting information and the driving data from the first memory.
Step 806, the electronic device starts the hardware device of the electronic device based on the start data, the setting information and the driving data.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
In the scheme, the electronic equipment can directly read the data required by UEFI starting in the AEP equipment, reduce the copying times of target data and further improve the UEFI initialization speed; UEFI initialization speed is improved by directly reading UEFI setting information from AEP; and the UEFI initialization speed is improved by reducing the initialization operation of the peripheral.
