Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The X86 architecture processor is the most mature architecture, is also a server architecture commonly adopted by the Internet industry and data centers, and is widely adopted by various industries because of stability, maturity and comprehensive support system application. One of the X86 architecture processor core functions is to support a hyper-threading function, i.e., one physical processor core may support 2 logical threads, and if the hyper-threading function is turned off, one physical processor core may support only 1 logical thread. With the improvement of chip process and chip technology level, one chip of the x86 architecture processor can support 64 physical cores, 128 logic threads can be supported when the hyper-threading is started or enabled, 128 physical cores and 256 logic threads can be supported at maximum in two paths, the early capacity of the overall performance is improved by 8 times, and the performance is improved in a crossing mode.
At present, most of operating systems used by terminal clients are free and open-source centos versions are old and versions of system kernels are old, when the system versions and the system kernel versions are not replaced, new functions cannot be supported or partial functional characteristics of the latest x86 architecture processor are supported, and when the hyper-threading functions of the processor are started, normal starting cannot be achieved and downtime occurs.
Therefore, the application correspondingly provides a basic input/output system hyper-threading operation scheme which can realize the basic input/output system hyper-threading operation under the condition that the system version and the system kernel version do not need to be replaced.
Referring to fig. 1, the embodiment of the application discloses a method for operating a basic input/output system hyper-threading, which comprises the following steps:
step S11: and starting the basic input/output system to judge whether the hyper-threading function is started or not.
In this embodiment, the client does not accept the system version upgrade or the system kernel version upgrade, and does not agree to modify the system boot startup parameters but has to support the x86 architecture 64 core processor, so the support can only be performed by the basic input output system (Basic Input Output System, i.e. BIOS). When the hyper-threading function is not started according to the 64-core dual-path processor, the system can be started normally and all functions are normal under the system, and the problem that the system is down and cannot enter the system can occur when the hyper-threading function of the processor in the basic input/output system is started and 256-core threads are arranged under the system, so that the BIOS starts the hyper-threading function, and whether the hyper-threading function is started needs to be judged first is solved.
Step S12: if so, the local advanced programmable interrupt mode is set to the target interrupt mode and the total number of first threads of all hyper threads is determined.
It will be appreciated that if turned on, it is necessary to further determine the total number of first threads for all hyper threads, and thus set the local advanced programmable interrupt mode to the target interrupt mode, i.e., set the local APIC (Advanced Programmable Interrupt Controller) mode to X2APIC.
Step S13: and judging whether the total number of the first threads is larger than a preset threshold value, and if so, determining a target hyper-thread from all the hyper-threads.
It can be understood that, only after the hyper thread function related to the processor in the basic input/output system is turned on, when the total number of the first threads exceeds 255, that is, 256 hyper threads, the system is down and the system cannot be accessed, so that it needs to be determined whether the total number of the first threads is greater than a preset threshold, that is, whether the total number of the first threads is greater than 255, and if so, the target hyper thread is determined from all the hyper threads, for example, the 256 th hyper thread is determined to be the target hyper thread.
In this embodiment, after determining whether the total number of the first threads is greater than a preset threshold, the method further includes: if the total number of the first threads is not larger than the preset threshold value, a plurality of advanced programmable interrupt controller description tables are created according to the total number of the first threads, and all the hyper threads are adjusted to be in an on state. It should be noted that if the total number of first threads is determined to be not greater than the preset threshold, i.e. the total number of first threads is not greater than 255, a plurality of advanced programmable interrupt controller description (Multiple APIC Description Table, i.e. MADT) tables may be created directly according to the actual number of threads, i.e. the total number of first threads, i.e. the actual number of threads is 100, and then the MADT tables may be created according to 100, and the hyper-threading function of each core number may be enabled, i.e. all hyper-threads may be adjusted to be in an on state.
Step S14: and adjusting the target hyper-thread to be in a closed state, and entering a corresponding operating system so that the operating system runs the hyper-thread in an open state.
In this embodiment, when it is determined that the total number of the first threads is not greater than the preset threshold, the corresponding operating system is entered so that the operating system runs all the hyper threads, so that all the hyper threads at this time are in an on state, and the operating system can run all the hyper threads.
In this embodiment, the adjusting the target hyper-thread to be in the off state and entering the corresponding operating system so that the operating system runs the hyper-thread in the on state includes: adjusting the target hyper-threads to be in a closed state, and determining the total number of second threads of all the hyper-threads except the target hyper-threads; and creating a plurality of advanced programmable interrupt controller instruction tables according to the total number of the second threads, and entering a corresponding operating system so that the operating system runs the hyper-threads in an on state. When the total number of the hyper threads exceeds a preset threshold, for example, more than 255, and is 256 hyper threads, the enable bit and the on-line capability bit of the core information of the CPU (Central Processing Unit, namely, the central processing unit) of the last hyper thread are set to 0, namely, the enable bit and the on-line capability bit of the central processing unit core of the target hyper thread are set to be low, so that the central processing unit core of the target hyper thread is adjusted to be in a closed state, namely, the 256 hyper thread function of the processor is closed when the system is entered, and a plurality of high-level programmable interrupt controller description tables are created according to the total number of the second threads.
The application has the beneficial effects that: starting a basic input/output system to judge whether a hyper-threading function is started or not; if the current thread is started, setting a local advanced programmable interrupt mode as a target interrupt mode, and determining the total number of first threads of all the hyper threads; judging whether the total number of the first threads is larger than a preset threshold value, and if so, determining a target hyper-thread from all the hyper-threads; and adjusting the target hyper-thread to be in a closed state, and entering a corresponding operating system so that the operating system runs the hyper-thread in an open state. Therefore, if the hyper-threading function is started, after the local advanced programmable interrupt mode is set to the target interrupt mode, whether the total number of the first threads of all the hyper-threading is larger than a preset threshold value is judged, if so, the target hyper-threading is closed, so that the operating system runs the hyper-threading in the starting state, namely, the basic input/output system hyper-threading can be realized under the condition that the system version and the system kernel version are not required to be replaced.
Referring to fig. 2, the embodiment of the application discloses a specific method for operating a hyper-threading of a basic input/output system, which comprises the following steps:
step S21: and starting the basic input/output system to judge whether the hyper-threading function is started or not.
Step S22: if so, the local advanced programmable interrupt mode is set to the target interrupt mode and the total number of first threads of all hyper threads is determined.
Step S23: if the hyper-threading function is judged not to be started, the corresponding operating system is accessed, so that the operating system runs the hyper-threading.
It can be understood that, only the hyper thread function of the processor in the basic input/output system is turned on, and when the total number of the first threads exceeds 255 or 256 hyper threads, the system is down and cannot enter the system, so if it is determined that the hyper thread function is not turned on, no processing is needed, and after entering the corresponding operating system, the operating system can run the hyper thread.
Step S24: and judging whether the total number of the first threads is larger than a preset threshold value, and if so, determining a target hyper-thread from all the hyper-threads.
Step S25: and adjusting the target hyper-thread to be in a closed state, and entering a corresponding operating system so that the operating system runs the hyper-thread in an open state.
In this embodiment, the enable bit and the online capability bit of the central processing unit kernel of the target hyper-thread are set to be low, and all hyper-threads except the target hyper-thread in the hyper-threads are adjusted to be in an on state; and entering a corresponding operating system so that the operating system runs the hyper-threading in the starting state.
Adjusting the target hyper-threads to be in a closed state, and determining the total number of second threads of all the hyper-threads except the target hyper-threads; and creating a plurality of advanced programmable interrupt controller instruction tables according to the total number of the second threads, and entering a corresponding operating system so that the operating system runs the hyper-threads in an on state.
Therefore, the method and the device firstly judge whether the hyper-threading function is started or not, if the hyper-threading function is not started, no processing is needed, if the hyper-threading function is started, whether the total number of the first threads of all the hyper-threading is larger than the preset threshold value is further judged, if the total number of the first threads of all the hyper-threading is larger than the preset threshold value, the target hyper-threading is closed, so that the operating system runs the hyper-threading in the starting state, and the basic input/output system hyper-threading operation can be realized under the condition that the system version and the system kernel version are not needed to be replaced.
Referring to fig. 3, the embodiment of the application discloses another specific method for operating a hyper-threading of a basic input/output system, which comprises the following steps:
step S31: and starting the basic input/output system to judge whether the hyper-threading function is started or not.
When the user does not accept the system version upgrade or the system kernel version upgrade, nor does the user agree to modify the system boot startup parameters, but has to support the x86 architecture 64 core processor, support can only be provided through the bios aspect. When the hyper-threading function is not started according to the 64-core dual-path processor, the system can be started normally and all functions are normal under the system, and the problem that the system is down and cannot enter the system can occur when the hyper-threading function of the processor in the basic input/output system is started and 256-core threads are arranged under the system, so that the BIOS starts the hyper-threading function, and whether the hyper-threading function is started needs to be judged first is solved.
Step S32: if so, the local advanced programmable interrupt mode is set to the target interrupt mode and the total number of first threads of all hyper threads is determined.
Step S33: and judging whether the total number of the first threads is larger than a preset threshold value, and if so, determining a target hyper-thread from all the hyper-threads.
Step S34: and adjusting the central processor core of the target hyper-thread to be in a closed state, and adjusting all the hyper-threads except the target hyper-thread to be in an open state.
In this embodiment, the adjusting the central processor core of the target hyper-threading to be in a closed state includes: and setting the enable bit and the online capability bit of the central processor core of the target hyper-threading to be low. For example, when the total number of hyper threads exceeds 255, i.e., 256 hyper threads, then the enable bit and the on-line capability bit of the CPU core information of the last hyper thread are set to 0 to be turned off, i.e., the 256 th hyper thread function of the processor is turned off when entering the system, and a MADT table is created.
Step S35: and entering a corresponding operating system so that the operating system runs the hyper-threading in the starting state.
Therefore, if the hyper-threading function is started, the application sets the local advanced programmable interrupt mode as the target interrupt mode to judge whether the total number of the first threads of all the hyper-threading is larger than the preset threshold, if so, the enable bit and the online capacity bit of the central processing unit kernel of the target hyper-threading are set to be low potential, so that the operating system can operate the hyper-threading in the starting state, i.e. the basic input/output system hyper-threading operation can be realized under the condition that the system version and the system kernel version are not required to be replaced.
The following describes the present application by taking a specific basic input/output system hyper-threading operation schematic diagram as an example shown in fig. 4.
1) And starting the basic input/output system to judge whether the hyper-threading function is started or not. Since the problem that the system is down and cannot enter the system occurs when the hyper thread function of the processor is exclusively started in the basic input/output system and the total number of the first threads exceeds 255 or 256 hyper threads is solved, if the hyper thread function is not started, no processing is needed, and the operating system can run the hyper thread after entering the corresponding operating system.
2) If the current thread is started, setting a local advanced programmable interrupt mode as a target interrupt mode, and determining the total number of first threads of all the hyper threads;
if the thread is not started, no processing is needed, and the corresponding operating system is only needed to be accessed, so that the operating system runs the hyper-threading.
3) And judging whether the total number of the first threads is larger than a preset threshold value, and if so, determining the target hyper-thread from all the hyper-threads.
When the total number of hyper-threads exceeds 255, then the last hyper-thread is determined to be the target hyper-thread.
For example, when the total number of hyper threads does not exceed 255, the MADT table is created according to the actual number of threads and the hyper thread function of each core is enabled to enter the corresponding operating system so that the operating system runs all the hyper threads.
4) And adjusting the target hyper-thread to be in a closed state, and entering a corresponding operating system so that the operating system runs the hyper-thread in an open state. The CPU kernel of the target hyper-threading is adjusted to be in a closed state, and hyper-threading except the target hyper-threading in all the hyper-threading is adjusted to be in an open state; and entering a corresponding operating system so that the operating system runs the hyper-thread in an on state. The adjusting the central processor core of the target hyper-threading to be in a closed state specifically comprises the following steps: the enable bit and the online capability bit of the central processor core of the target hyper-threading are set to low. It should be noted that after the target hyper-thread is adjusted to be in the off state, the total number of second threads of the hyper-threads except the target hyper-thread in all the hyper-threads needs to be determined; and creating a plurality of high-level programmable interrupt controller instruction tables according to the total number of the second threads, and entering a corresponding operating system so that the operating system runs the hyper-threads in an on state, and starting and guiding the basic input output system into the operating system, wherein the number of the processor threads under the current system can be checked to be 255 by using an lscpu command under the system.
