Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The invention provides a method and a system for improving the operation efficiency of a Loongson platform system disk.
As shown in fig. 1, in a first embodiment of a method for improving the operation efficiency of a Loongson platform system disk provided by the present invention, the method for improving the operation efficiency of the Loongson platform system disk is applied to a Loongson platform; as shown in fig. 2, the Loongson platform comprises a Loongson processor, a PMON module, a memory, a bridge piece and a first solid state disk; the memory is in communication connection with the Loongson processor; the PMON module is in communication connection with the Loongson processor through an SPI interface; the first solid state disk is in communication connection with the Loongson processor through NVME protocol, and specifically: the bridge piece is in communication connection with the Loongson processor through an HT bus; the first solid state disk adopts NVME protocol and is in communication connection with the bridge chip through a PCIE (fully called PCI-Express, peripheral component interconnect Express, serial high-speed interface device) interface; the embodiment comprises the following steps:
Step S110: and after the Loongson platform is powered on, the PMON module loads an NVME driver.
Specifically, the current PMON module defaults to support a hard disk (i.e., a mechanical hard disk) adopting a SATA interface, namely, corresponding drivers are automatically loaded; according to the method, the first solid state disk is used as a system disk, and the first solid state disk is a hard disk adopting an NVME protocol, so that an NVME driver needs to be loaded, and preparation is made for starting from the NVME later; namely, by loading the NVME driver, the PMON module can identify and guide the operating system in the first solid state disk.
Step S120: the PMON module identifies whether an operating system file (e.g., an operating system file for a kylin operating system) exists in the first solid state disk through an NVME driver.
Step S130: if the operating system file exists in the first solid state disk (i.e. the first solid state disk is used as a system disk at this time), the PMON module checks whether the operating system file in the first solid state disk has completed correct configuration corresponding to the NVME driver.
Specifically, besides loading the NVME driver on the PMON module, the invention also needs to add the function of the PMON module for identifying the file driver in the first solid state disk; so that the operating system files have completed the correct configuration corresponding to the NVME driver, specific examples are:
1. Ensuring that the PMON module can identify the first solid state disk:
the PMON module operates to send a command devls to the processing chip of the first solid state disk, and if the nvme0 is detected by the command devls, the PMON module determines that the first solid state disk is identified, the step S120 and the following steps can be continued.
If the command devls does not detect nvme0, the PMON module determines that the first solid state disk is not recognized, namely the first solid state disk is not recognized; the following code needs to be executed:
1. the Bonito.3a4000_7a-d file in the PMON module is annotated, if the Bonito.3a4000_7a-d file is not in the PMON module, the value is directly changed into Bonito.3a4000_7a, and the specific codes are as follows:
/run/media/eric/28e04387-2553-43d3-a3e3-f2b6981df873/3A4000/2149/pmon-loongson3-2149/Targets/Bonito3a4000_7a/conf/Bonito.3a4000_7a

2. and then annotating all PCIE interfaces according to preset description codes, wherein the preset description codes are as follows:
/run/media/eric/28e04387-2553-43d3-a3e3-f2b6981df873/3A4000/2149/pmon-loongson3-2118/pmon/arch/mips/ls7a/ls7a_init.S
# if 0// needs to change 1 to 0 in this place, this file needs to modify 5 places in total, meaning that this function of turning off all PCIE's, if not turned off, no NVME disk can be identified under the system,
if it is desired to identify the disc under PMON, the following 2 notes should be removed under/run/media/eric/28 e04387-2553-43d3-a3e3-f2b6981df873/3A4000/2149/PMON-loongson 3-2149/Targets/bonito3a4000_7a/conf/bonito.3a4000_7a:
//pcinvme

//nvme
at pcinvme?
3. After the steps are executed, the PMON module sends a command devls to the processing chip of the first solid state disk again, whether the first solid state disk is identified is judged by judging whether nvme0 is detected by the command devls, if not, the first solid state disk cannot be identified, and if the first solid state disk is identified, the problem of the first solid state disk is solved, the PMON module determines that the first solid state disk fails, and an engineer designing the first solid state disk is required to configure the disk.
After the first solid state disk is normally identified and an operating system (e.g., a kylin system) is already installed in the first solid state disk, the kylin system can be manually started:
the following 3 commands for manual system start-up under pmon
load /dev/fs/ext2@nvme0/boot/vmlinuz-3.10.0
initrd /dev/fs/ext2@nvme0/boot/initramfs-3.10.0.img
g console=ttyS0,115200 loglevel=7 root=/dev/nvme0n1p1
2. If the system is wanted to be automatically started, the PMON module changes the running configuration file so as to enable the operating system in the first solid state disk to be automatically started, and particularly, the codes of the following 2 positions need to be changed:
1. in the PMON module:
the/run/media/eric/28 e04387-2553-43d3-a3e3-f2b6981df873/3A4000/2149/pmon-loongson3-2149/pmon/common/main.c file;
the meaning of the code is that the code automatically runs under PMON, and the manual operation is changed into automatic operation
//try to read boot.cfg from nvme disk third
rootdev = "/dev/fs/ext2@nvme0"；
The addition of this line is only necessary, and other contents are used for the convenience of positioning, and for the system under the automatic execution/dev/fs/ext2@nvme0, if this sentence is not added, the PMON cannot automatically load the system.
sprintf(path, "%s/boot/boot.cfg", rootdev)；
if (check_config(path) == 1)
{
sprintf(path, "bl -d ide %s/boot/boot.cfg", rootdev)；
if (do_cmd(path) == 0)
{
show_menu = 0；
free(path)；
path = NULL；
return 1；
}
}else{
sprintf(path, "%s/boot.cfg", rootdev)；
if (check_config(path) == 1)
{
sprintf(path, "bl -d ide %s/boot.cfg", rootdev)；
if (do_cmd(path) == 0)
{
show_menu = 0；
free(path)；
path = NULL；
return 1；
}
}
}
int check_user_password()
2. The PMON module creates a boot.cfg file in the first solid state disk, copies the initrd.gz file under a boot folder to create a boot starting option, and loads boot configuration.
When the operating system is reinstalled on the first solid state disk, the first solid state disk is used as a storage hard disk (namely, the first solid state disk is not only a system hard disk but also a storage hard disk at the moment), and the PMON module creates a boot file under the nvme0n1p1 catalog and copies and writes preset contents, wherein the specific preset contents are as follows:
[root@localhost boot]# cat boot.cfg
timeout 3
default 0

if yes, step S140 is executed: and the PMON module guides an operating system in the first solid state disk to start.
Specifically, after the preparation, the start-up file of the operating system is also started from the SATA disk by default, so that the start-up sequence needs to be changed to preferentially start up the operating system in the first solid state disk.
Step S150: and if the operating system file does not exist in the first solid state disk, the Loongson processor generates a file fault log and stores the file fault log in the first solid state disk.
Specifically, if the first solid state disk does not have an operating system file, the operating system file in the first solid state disk cannot be identified by the PMON module, or the first solid state disk fails and cannot be read and written normally, and maintenance and investigation are required, so that the Loongson processor generates a file fault log and stores the file fault log in the first solid state disk, so that subsequent maintenance and investigation are facilitated.
The read-write speed of the solid state disk adopting NVME (Non-Volatile Memory express, nonvolatile high-speed storage) communication protocol is faster than that of the traditional mechanical hard disk, the highest read speed of the NVME protocol solid state disk in the current mainstream can reach more than 3500MB/s, and the phase difference is about 6 times compared with the speed of about 560MB/s of the solid state disk adopting the SATA interface; and the solid state disk is smaller in size, and vibration cannot be generated in the running process of the solid state disk.
The Loongson platform adopts a PMON (Programmable read only memory Monitor, programmable read-only memory programming) module as a basic input-output system (equivalent to BIOS, namely Basic Input Output System); the PMON module is used for detecting hardware, driving basic peripheral equipment and guiding an operating system.
According to the method for improving the operation efficiency of the Loongson platform system disk, the NVME driver is loaded on the PMON module, the operating system files in the first solid state disk are identified through the NVME driver based on the PMON module, then the PMON module checks whether the operating system files in the first solid state disk are correctly configured corresponding to the NVME driver, if so, the PMON module guides the operating system in the first solid state disk to start, so that the PMON module supports the solid state disk adopting the NVME communication protocol as a system disk, and compared with the traditional mechanical hard disk, the solid state disk adopting the NVME communication protocol has higher reading and writing speeds, and the technical defect that the operation speed of the system disk is low in the Loongson platform in the prior art is overcome.
In addition, compared with the traditional mechanical hard disk used as a system disk, the system disk is prepared from the solid state hard disk adopting the NVME protocol, and the read-write speed of the system disk is greatly improved; the hardware design of the Loongson platform is simplified, and the solid state disk is smaller than the mechanical hard disk in size, so that the space is saved, and the miniaturization design of the Loongson platform is facilitated; in addition, the solid state disk adopting the NVME protocol is used as the configurable speed, so that the solid state disk is more convenient to use, has idle speed control, and can reduce the running power consumption of the Loongson platform. Meanwhile, the solid state disk can be used as a data disk of the Loongson platform, so that the read-write data of the data disk are further improved, and the size and the operation power consumption of the Loongson platform are further reduced.
Compared with the traditional mechanical hard disk connected with the SATA interface, the solid state disk adopting the NVME protocol has the following advantages:
the relationship between NVME protocol and PCIE interface is: NVME is a communication protocol applied over PCIE interfaces.
The relationship between SATA interface and AHCI protocol (collectively Serial ATA Advanced Host Controller Interface, serial ATA advanced master interface/advanced host controller interface) is: the AHCI is a communication protocol applied over the SATA interface.
Compared with the AHCI protocol, the NVME protocol has several times of improvement and reasons of communication performance:
1.1: IO queue number:
the SSD queue depth under the AHCI specification is 32 IOPS capability, while the NVME protocol can promote the queue depth from 32 to 64000, thereby greatly improving the IOPS capability;
1.2: the NVME protocol is full duplex mode
The SATA interface is half duplex, parallel transmission, and the NVME protocol (PCIE interface) is full duplex, serial transmission, thereby greatly improving the speed.
1.3: PCIE channels are more numerous
The SATA interface has only one channel.
The PCIE protocol can extend the bandwidth by increasing the number of channels, and can have 32 channels at most, where the more the number of channels is, the faster the speed is; in practice, how many channels are used can be determined according to the requirements, and like the PCIE slots with different lengths can be seen on the main board, the PCIE slots have x1, x4, x16 and the like, and the requirements of different devices can be met.
1.4: the PCIE protocol is continually updated iteratively.
SATA 3.0 protocol was published 2009, and since then no more updates were made, with a speed of 500MB/s at the highest; PCIE specification version updating is always in updating, and each updating brings great improvement in speed; PCIE1.0 is born in 2002, PCIE2.0 is standardized to be discharged in 2007, PCIE3.0 is issued after three years, and the PCIE1.0 is also a main PCIE design standard at present, and the speed of x16 can reach 16GB/S. Currently, PCIE6.0 standard has been issued: the read-write speed is 8 times of PCIE3.0, and the PCIE can be commercially used in 2023.
1.5: the delay can be greatly reduced.
The NVME protocol standard is oriented to the PCIE interface and the solid state disk, and the direct connection of the native PCIE channel and the CPU can avoid the delay caused by the communication between an external controller (PCH) of the SATA and SAS interface and the CPU. The delay of NVME protocol standard is less than half of that of AHCI protocol, and the NVME protocol simplifies the calling mode, so that a register is not required to be read when a command is executed; while each command under the AHCI protocol requires reading the registers 4 times, 8000 CPU cycles are consumed, resulting in a delay of approximately 2.5 mus.
2. The automatic power consumption state switching and dynamic power consumption management functions greatly reduce power consumption.
The NVME protocol is added with automatic power consumption state switching and dynamic energy consumption management functions, and can be controlled at an extremely low level very quickly when in idle, and the NVME standard solid state disk has a larger advantage than the current mainstream AHCI protocol solid state disk in power consumption management.
4. The occurrence of NVME standards solves the problem of drive applicability between solid state disks adopting different PCIE interfaces.
In a second embodiment of the method for improving the operation efficiency of the Loongson platform system disk according to the present invention, based on the first embodiment, step S120 further includes the following steps:
Step S210: and if the operating system files exist in the first solid state disk, the PMON module judges whether at least two different operating system files exist in the first solid state disk.
Step S220: if the operation system file exists, the Loongson processor acquires a selection instruction input by a user, and marks the operation system file corresponding to the selection instruction as a first target file.
Specifically, here, a selection instruction is input by a user through an input module.
Step S230: the PMON module checks whether the first object file has completed the correct configuration corresponding to the NVME driver.
If yes, go to step S240: and the PMON module guides the starting of an operating system corresponding to the first target file in the first solid state disk.
Specifically, when a plurality of different operating system files (for example, a kylin operating system and a Windows operating system) exist in the first solid state disk, through the scheme of the embodiment, a user can autonomously select which operating system to start.
In a third embodiment of the method for improving the operation efficiency of the Loongson platform system disk according to the present invention, based on the second embodiment, step S210 further includes the following steps:
Step S310: if so, the Loongson processor judges whether an operating system file corresponding to a preset operating system exists in the first solid state disk.
Specifically, the preset operating system is the operating system (e.g. kylin operating system) that is preferentially started by the user.
Step S320: if the first solid state disk has the operating system file corresponding to the preset operating system, the PMON module marks the operating system file corresponding to the preset operating system as a second target file.
Step S330: the PMON module checks whether the second object file has completed the correct configuration corresponding to the NVME driver.
