Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The application discloses a system starting method, a flow chart of which is shown in fig. 1, comprising the following steps:
step S11, in the system starting process, controlling the first boot loader to run;
step S12, when the first boot loader outputs the running data, the first processor determines whether a preset parameter is a first preset value, where the preset parameter is used to indicate whether the first boot loader is in a state to be debugged;
step S13, if the preset parameter is the first preset value, in the process of controlling the first boot loader to run, storing running data of the first boot loader during running, so as to debug the first boot loader based on the running data.
The bootloader is a program which runs before the kernel of the operating system runs, and can initialize hardware equipment and establish a mapping map of a memory space through the bootloader, so that the software and hardware environment of the system reaches an adaptive state.
In the system starting process, when a first boot loader bootloader in a Basic Input Output System (BIOS) loads and runs, no matter a problem occurs in a first stage shim or a problem occurs in a second stage grub, debugging information related to the abnormality cannot be completely output to a serial port, so that the debugging information cannot be received by a debugger, and the system cannot be normally started.
Based on this, in the scheme, in the process of running the first boot loader, if it is determined that the first boot loader is in the state to be debugged, the running data in the running process of the first boot loader is stored, so that the first boot loader can be debugged based on the stored running data.
Specifically, in the system starting process, when the first processor BIOS is started, the first boot loader runs, and in the running process of the first boot loader, the first processor determines whether a certain preset parameter is a first preset value, and if the certain preset parameter is the first preset value, it indicates that the first boot loader is in a state to be debugged and needs to store running data of the first boot loader; if the current first boot loader program is not the first preset value, the current first boot loader program does not need to be debugged, the first boot loader program normally runs, and the subsequent system starting process is continuously started.
The preset parameter is a variable DEBUG added in the unified extensible firmware interface UEFI, and default values may be set for the variable, for example: false, when the variable is a default value, the variable is a non-first preset value, and the running data of the first boot loader does not need to be stored; when the variable is the first preset value, the first preset value is as follows: true, at this time, the running data of the first boot loader needs to be stored.
It should be noted that the storage of the running data of the first boot loader is not necessarily performed only when the first boot loader runs abnormally, but is necessarily performed only when the preset parameter is the first preset value, and the storage of the running data of the first boot loader is performed as long as the preset parameter is the first preset value.
As shown in fig. 2, includes: a first boot loader 21, a first processor 22 and a second processor 23.
The first boot loader Bootloader is partially stored in the first processor BIOS, and the rest is stored in the second processor CPU. The method comprises the following steps that a first stage shim and a second stage grub can be executed in the running process of a first boot loader, a debugging switch is arranged in each of the first stage shim and the second stage grub, the first boot loader can be debugged only when the two debugging switches are both in an open state, and the embodiment disclosed by the scheme is realized when the two debugging switches are both in the open state; in addition, a preset parameter Debug needs to be set in the first boot loader, and whether the running data of the first boot loader needs to be stored is determined according to the value of the preset parameter.
Further, a Write module Write handler may be further added to the first boot loader Bootloader, and the Write module Write handler is configured to check whether a value of the preset parameter is the first preset value. The write module may be located in a portion of the first boot loader that is located in the BIOS of the first processor, i.e., the write module is located in a portion of the first boot loader that is stored in the first processor.
The embodiment discloses a system starting method, wherein in the system starting process, a first boot loader is controlled to run, when the first boot loader outputs running data, a first processor determines whether a preset parameter is a first preset value, and the preset parameter is used for indicating whether the first boot loader is in a state to be debugged; if the preset parameter is a first preset value, storing running data of the first boot loader during running in the process of controlling the first boot loader to run so as to debug the first boot loader based on the running data. In the scheme, in the starting process of the system, when the first processor determines that the first boot loader is in the state to be debugged, the running data of the first boot loader during running is stored, so that a debugger can debug the first boot loader directly based on the stored running data, and the problem that the system cannot be started normally is avoided.
The embodiment discloses a system starting method, a flow chart of which is shown in fig. 3, and the method comprises the following steps:
step S31, in the system starting process, controlling the first boot loader to run;
step S32, when the first boot loader outputs the running data, the first processor determines whether a preset parameter is a first preset value, where the preset parameter is used to indicate whether the first boot loader is in a state to be debugged;
step S33, if the preset parameter is the first preset value, in the process of controlling the first boot loader to run, storing running data of the first boot loader during running, so as to debug the first boot loader based on the running data;
and step S34, the control system restarts, and the first processor or the second processor reads and outputs the stored running data of the first boot loader during running, so as to debug the first boot loader based on the output running data.
The first processor is different from the second processor, and the second processor is used for controlling the operation of the system after the system is started.
If the preset parameter is determined to be the first preset value, the first boot loader is in a to-be-debugged state, and the running data of the first boot loader during running is stored based on the first boot loader being in the to-be-debugged state, and the running data is stored, so that the first boot loader can be debugged based on reading of the stored running data.
After the running data of the first boot loader is stored, the system is controlled to restart, so that the stored running data can be read in the restarting process, and the first boot loader is not executed again.
The method includes that a first boot loader is directly operated in a starting process of a system when running data is stored, the first boot loader is determined to be in a to-be-debugged state in the operating process, then, after the running data is read, the first boot loader cannot be controlled to operate again according to the previous flow in a restarting process, and if the first boot loader is controlled to operate again, the first boot loader still can be in the to-be-debugged state, and the system cannot be normally started. Therefore, after the running data of the first boot loader is stored, in the process of restarting the first boot loader, the running data is directly read so as to be adjusted based on the running data, only after the first boot loader is debugged based on the running data, the preset parameter can be adjusted back to the non-first preset value, at this time, the system is restarted, the detected preset parameter is the non-first preset value when the first boot loader is controlled to run, the normal starting process of the first boot loader can be completed, and the normal starting of the system is realized.
When the control system is restarted, the first processor may read the stored operation data, or the second processor may read the stored operation data, and the first processor may be: the second processor may be a central processing unit CPU, that is, the second processor may read and output the running data of the first boot loader stored in the last boot process in the system boot process, or may read and output the running data after the system boot is completed.
The first processor or the second processor outputs the stored operation data, which may be: the first processor or the second processor reads the running data of the first boot loader in the last system starting process stored in the memory and outputs the running data through the display screen of the electronic device, so that an operator can determine which part of the first boot loader is to be debugged based on the running data output by the display screen, or what state the first boot loader needs to be debugged to, and the like.
The operating data of the first boot loader during operation is stored, and may be sent to the platform management system through the first processor for storage, or may be stored in the non-volatile memory for storage.
The first processor sends the running data of the first boot loader to the BMC end through an interface connected with the BMC, the BMC end completes storage, and the BMC end can directly display the relevant running data.
The non-volatile memory is in the electronic device, and the interface for the first processor to write the operation data into the non-volatile memory may multiplex a Serialization Action in a specific specification defined by the ACPI specification, where the specific specification may be: the ERST table mechanism, which can define what devices the back-end word group is. The specific data writing can call the method corresponding to EXECUTE _ OPERATION, and the method completes the unloading of the OPERATION data.
The specific unloading method may be different according to a position of the Error Log Address Range defined in the ACPI, and the first processor may store the running data in the non-volatile random access memory NVRAM or the random access memory RAM.
If the operation data is stored in the NVRAM, the operation data of the first boot loader is directly stored in the nonvolatile memory; if the operation data is stored in the RAM, since the RAM is only an intermediate cache, the first processor may transfer and store the operation data from the RAM to other nonvolatile memories, such as: the hard disk or the hard disk is stored through a network, namely, the hard disk or the hard disk is stored to the cloud.
The embodiment discloses a system starting method, wherein in the system starting process, a first boot loader is controlled to run, when the first boot loader outputs running data, a first processor determines whether a preset parameter is a first preset value, and the preset parameter is used for indicating whether the first boot loader is in a state to be debugged; if the preset parameter is a first preset value, storing running data of the first boot loader during running in the process of controlling the first boot loader to run so as to debug the first boot loader based on the running data. In the scheme, in the starting process of the system, when the first processor determines that the first boot loader is in the state to be debugged, the running data of the first boot loader during running is stored, so that a debugger can debug the first boot loader directly based on the stored running data, and the problem that the system cannot be started normally is avoided.
The embodiment discloses a system starting method, a flow chart of which is shown in fig. 4, and the method comprises the following steps:
step S41, in the system starting process, controlling the first boot loader to run;
step S42, when the first boot loader outputs the running data, the first processor determines whether a preset parameter is a first preset value, where the preset parameter is used to indicate whether the first boot loader is in a state to be debugged;
step S43, if the preset parameter is the first preset value, in the process of controlling the first boot loader to run, storing running data of the first boot loader during running, so as to debug the first boot loader based on the running data;
step S44, controlling the system to restart, wherein in the system restarting process, the first processor adjusts the preset parameter to a second preset value and controls a second boot loader to run;
and step S45, when the system is started to finish running, the second processor reads and outputs the stored running data.
After the running data of the first boot loader is stored, if the stored running data is to be read, the system needs to be controlled to restart, in the restarting process of the system, the first processor runs firstly, and when the first processor runs, the first processor adjusts the preset parameter to the second preset value, namely the first preset value, so that the normal running of the boot loader is facilitated, and the problem that the boot loader cannot run normally due to the fact that the preset parameter is the first preset value is solved.
After the preset parameter is adjusted to the second preset value, the first boot loader is still in a state to be debugged, and therefore, in order to ensure normal startup of the system, the first processor controls running of the second boot loader, which is a boot loader capable of running normally without debugging except the first boot loader.
The first processor controls the second boot loader to run so as to ensure the smooth start of the system, when the system is in a running state after the system is started, the second processor, namely the CPU controls the running of the system, so that under the condition of ensuring the normal running of the system, the second processor can directly read the running data of the first boot loader stored in the process of starting the system last time from the memory or the BMC and display the running data after reading the running data, thereby realizing that the running data of the first boot loader in a state to be debugged can be read and displayed in the process of ensuring the normal running of the system, so as to debug the first boot loader and ensure that the first boot loader is in a state which does not need to be debugged and can run normally.
When the second processor reads the stored running data of the first boot loader, the stored running data can be displayed in a file form through the pstore architecture. Specifically, in the process of starting the operating system, according to an operation defined in an ERST table mechanism of the ACPI, it is determined whether there is running data of the first boot loader stored in the last system starting process, and if so, a GET _ RECORD _ IDENTIFIER operation sending instruction is sent to the first processor, so that the first processor reads the running data of the first boot loader from the rear-end nonvolatile memory specified by the Error Log Address Range.
Further, when the control system is restarted, the first processor or the second processor reads and outputs the stored running data of the first boot loader during running, and the step may further be:
in the process of restarting the system, the first processor reads the stored running data through the reading module, outputs the running data to the serial port terminal, and stores the running data in the first boot loader running log.
When the system is restarted, the system is not directly enabled to read the running data of the first boot loader in the last system starting process in the running state, but the running data is read in the starting state.
Specifically, when the system is started, the first processor firstly reads stored running data through the Read handler of the reading module, and when the reading module determines that the running data is not stored in the last system starting process, the first processor can determine that the current first boot loader does not need to be debugged, and starts the first boot loader according to a normal flow of system starting to enable the first boot loader to run normally and enable the operating system to run;
when the reading module determines that the running data is stored in the nonvolatile memory or the BMC in the last system starting process, the first boot loader is not controlled to be started any more, and the running data is called.
That is, in the system starting process, the schematic diagram of the normal starting flow is shown in fig. 5, and includes: the method comprises the steps that a first processor BIOS runs, a reading module Read handler in the first processor runs, the reading module determines whether running data of a first boot loader stored in the last system starting process is stored in a nonvolatile memory or not, if the running data of the first boot loader stored in the last system starting process is not stored in the nonvolatile memory, the reading module sends an instruction to a writing module Write handler in the first boot loader, at the moment, the first boot loader Bootloader runs, and the writing module judges whether a preset parameter Debug is a first preset value or not;
if the preset parameter is not the first preset value, namely the second preset value, the first boot loader normally runs, and then the second processor CPU runs, namely the operating system OS normally runs; if the preset parameter is a first preset value, storing running data of the first boot loader during running so as to read and output the running data of the first boot loader stored during last system starting when the system is restarted;
if the read module Readhandler in the first processor runs and determines that the nonvolatile memory stores the running data of the first boot loader stored in the last system starting process, the stored running data is read and output to the serial port terminal, so that an operator can debug the first boot loader based on the running data output to the serial port terminal and store the running data into the first boot loader running log.
That is to say, in the system starting method disclosed in this embodiment, when the control system is restarted and the stored data in the running of the first boot loader is read and output, the data can be read in the above two ways, that is, the second boot loader capable of running normally can be used for running, and after the system is started, the stored running data is read and output by the second processor; or, in the system restarting process, the first processor first determines whether the running data is stored through the reading module, and if the running data is stored, the running data is output to the serial port terminal, so that the debugging of the first boot loader is performed based on the running data. In the scheme, the stored running data can be read by any one of the above modes, one mode can be randomly selected for the system in the restarting process, the reading can also be performed based on a preset optimal mode, and the reading is performed by another mode when the optimal mode cannot be realized or does not have the execution condition.
The embodiment discloses a system starting method, wherein in the system starting process, a first boot loader is controlled to run, when the first boot loader outputs running data, a first processor determines whether a preset parameter is a first preset value, and the preset parameter is used for indicating whether the first boot loader is in a state to be debugged; if the preset parameter is a first preset value, storing running data of the first boot loader during running in the process of controlling the first boot loader to run so as to debug the first boot loader based on the running data. In the scheme, in the starting process of the system, when the first processor determines that the first boot loader is in the state to be debugged, the running data of the first boot loader during running is stored, so that a debugger can debug the first boot loader directly based on the stored running data, and the problem that the system cannot be started normally is avoided.
The embodiment discloses a system starting method, a flow chart of which is shown in fig. 6, and the method comprises the following steps:
step S61, in the system starting process, controlling the first boot loader to run;
step S62, when the first boot loader outputs the running data, the first processor determines whether a preset parameter is a first preset value, where the preset parameter is used to indicate whether the first boot loader is in a state to be debugged;
step S63, if the preset parameter is a second preset value, controlling the first boot loader to run; if the first boot loader runs abnormally, adjusting the preset parameters from the second preset value to the first preset value;
step S64, if the preset parameter is the first preset value, in the process of controlling the first boot loader to run, storing running data of the first boot loader during running, so as to debug the first boot loader based on the running data.
When the preset parameter is a second preset value, namely not the first preset value, at this time, based on the value of the preset parameter, the first boot loader can be determined to be in a normal state, debugging is not needed, and the first boot loader can normally run, so that the first processor controls the first boot loader to run, and the system can be in a normal running state after being started;
if the preset parameter is the first preset value, based on the value of the preset parameter, it may be determined that the first boot loader is in a state to be debugged and cannot normally run, and at this time, running data during running of the first boot loader may be stored, so that the first boot loader may be debugged based on the running data.
If the first processor determines that the preset parameter is the second preset value, the first boot loader is controlled to run, and in the running process of the first boot loader or when the preset parameter is determined, it is detected that the preset parameter is switched from the second preset value to the first preset value, it is indicated that the first boot loader runs abnormally, the first boot loader needs to be debugged, the starting and running of the first boot loader are stopped, and the running data of the first boot loader is stored.
The preset parameter is a first preset value or a second preset value, which may be determined based on whether the first boot loader can operate normally, that is, the system automatically adjusts the value of the preset parameter, and when the first boot loader is abnormal, the value of the preset parameter is set to the first preset value; and when the first boot loader can normally run, setting the value of the preset parameter as a second preset value.
In addition, the following may be also possible:
and obtaining an adjusting instruction output by the first processor or the second processor, and adjusting the preset parameter to be a first preset value or a second preset value based on the adjusting instruction.
That is, in this embodiment, the adjustment of the preset parameter value may be automatically implemented based on the judgment of whether the first boot loader can normally operate by the system, or may be manually set by an operator, that is, whether the manual setting requires setting whether the first boot loader is in a state to be debugged, or may be determined based on whether the first boot loader can normally operate, or may be implemented by debugging the first boot loader to update the system version based on design requirements or experimental requirements.
The manual setting of the value of the preset parameter may be performed on the first processor, that is, obtaining the adjustment instruction output by the first processor, or may be performed on the second processor, that is, obtaining the adjustment instruction output by the second processor.
The adjusting instruction output by the first processor is obtained, that is, in the system starting process, the first processor receives the adjusting operation of the operator, and the first processor outputs the adjusting instruction corresponding to the adjusting operation, as shown in Settings in fig. 5, that is, the operator inputs the first processor to adjust the preset parameter Debug, where the preset parameter Debug may be manually adjusted to a first preset value or manually adjusted to a second preset value.
The adjustment instruction output by the second processor is obtained, that is, in the system operation process, the second processor receives the adjustment operation of the operator, and the second processor outputs the adjustment instruction corresponding to the adjustment operation to the preset parameter stored in the first processor, as shown in Utility in fig. 5, that is, the input of the operator on the second processor, so as to adjust the preset parameter Debug, where the preset parameter may be manually adjusted to the first preset value, or the preset parameter may be manually adjusted to the second preset value.
Further, when the first processor determines that the preset parameter is the first preset value, no matter whether the first preset value is achieved by automatic adjustment of the system or manual operation of an operator, as long as the preset parameter is determined to be the first preset value, the system is controlled to restart, so that in the system starting process, when the first processor determines that the preset parameter is the first preset value, in the process of controlling the first boot loader to run, running data of the first boot loader during running are stored.
