Ceph: a unified, distributed file system designed for excellent performance, reliability and scalability.
LoongArch: a Loongson instruction system based on twenty years of CPU development and ecological construction accumulation in the Loongson department comprises an infrastructure part, vector instructions, virtualization, binary translation and other extension parts and nearly 2000 instructions.
Platform self-adaptation: besides configuration, plug-in and management tools, the Ceph also comprises a plurality of system function modules, codes related to the architecture exist in the system function modules, and the Ceph can self-adaptively select corresponding codes according to different architectures to ensure normal compiling and running.
The invention provides a method for adapting a domestic operating system to a Ceph, wherein the domestic operating system is based on a LoongArch architecture processor platform, and the Ceph is adapted to the domestic operating system of the LoongArch architecture processor platform by changing configuration and adding LoongArch architecture branches.
As shown in FIG. 1, the method of the present invention comprises the following steps:
step S1: ceph changes compilation configuration:
adding a branch of a LoongArch architecture in the Ceph and setting a branch compiling flow of the LoongArch architecture;
parameters of the LoongArch architecture are added to the coding configuration of the Ceph, so that the Ceph identifies and codes branches of the LoongArch architecture.
Step S2: ceph adds the longarch code:
the file of the LoongArch architecture and the LoongArch code are added in the branch of the LoongArch architecture of Ceph. Through step S2, a binary file suitable for the LoongArch architecture processor platform can be compiled, thereby ensuring that Ceph is compiled and run on the LoongArch architecture processor platform.
Step S3: platform self-adaptation:
the Ceph matches and implements the branches of the longarch architecture, identifying the interfaces of the longarch architecture processor platform through the longarch code, making the Ceph compatible with the longarch architecture processor platform.
Step S4: ceph is adapted to the domestic operating system of the LoongArch architecture processor platform.
The specific embodiment is as follows:
step S1: ceph changes the compiling configuration and constructs the branch of the LoongArch architecture;
adding a branch of a LoongArch architecture in the Ceph and setting a branch compiling flow of the LoongArch architecture; parameters of the LoongArch architecture are added to the compiled configuration of Ceph.
The parameters comprise a compiling parameter, a configuration checking parameter, a configuration information parameter and a context construction parameter.
Parameters for increased lonngarch are exemplified:
add LoongArch architecture branches and parameters:
elseif(CMAKE_CXX_COMPILER_ARCHITECTURE_ID STREQUAL "LOONGARCH")
string(APPEND _boost_ARCHITECTURE_TAG "lp")
configuring checking parameters: obj loonggarch 64 loonggarch 64.cpp
Configuration information parameters: PRINT _ MACRO (__ LOONgarch __)
Context construction parameters:
else if [ configure.builds /boost/architecture//loongarch64 : $(properties) : loongarch64 ]
{
return <architecture>loongarch64 ;
}
step S2: ceph adds the longarch code;
the method has the advantages that files of the LoongArch architecture and LoongArch codes are added in branches of the LoongArch architecture of the Ceph, and the Ceph is guaranteed to be compiled and run on a LoongArch architecture processor platform.
According to the characteristics of the longarch architecture, the longarch code added in Ceph is code specific to the branches of the longarch architecture, including some macro definitions, interface functions, assembly instructions, and the like.
Adding a LoongArch architecture file:
src/boost/boost/predef/architecture/loongarch64.h
code specific to the branches of the LoongArch architecture is exemplified by:
macro definition:
/* LOONGARCH */
#if defined(__loongarch64)
#define DUK_F_LOONGARCH64
#else
#define DUK_F_LOONGARCH32
#endif
interface function:
.file "ontop_loongarch64_lp64_elf_gas.S"
.text
.globlontop_fcontext
.align 3
.type ontop_fcontext,@function
ontop_fcontext:
# reserve space on stack
addi.d $sp, $sp, -160
…
assembling instructions:
ld.d $t0, $zero, 0xfffffffffffffff0
step S3: self-adapting of a platform;
the Ceph matches and implements the branches of the longarch architecture and identifies the interfaces of the longarch architecture processor platform through macro definitions in the longarch code, making the Ceph compatible with the longarch architecture processor platform.
Step S3 is to connect the Ceph generic code and the architecture code, and ensure the compatibility of the interface, so that the interface can be displayed and called.
It should be noted that, besides the LoongArch architecture processor platform, the Ceph also supports a plurality of architectures such as X86, ARM, MIPS, PPC, and the like, and the interfaces of these architectures are respectively implemented in different ways, which are distinguished by macro definitions of the architectures, so that in actual deployment, according to the actually identified architecture, corresponding branch codes are automatically matched and implemented, and the compatibility of the Ceph and the platform is achieved.
Therefore, in step S3, Ceph matches the corresponding architecture code and interface according to the architecture characteristics, and calls the interface to complete the compiling operation. And if the matched architecture is LoongArch, matching the LoongArch codes and interfaces, and if the matched architecture is not LoongArch, matching other architecture codes and interfaces. Through steps S1 and S2, the Ceph of step S3 may be matched to the longarch architecture, thereby completing the compatibility of the Ceph with the longarch architecture processor platform. The steps do not need to manually specify any parameter, and are completely and automatically identified, matched and implemented.
Step S4: ceph is adapted to the domestic operating system of the LoongArch architecture processor platform.
In the Ceph deployment tool Ceph-deployment, currently, only the international mainstream operating systems such as reddat, centros and suse are supported, and the domestic operating systems are not identified,
step S4 is to add a homemade operating system tag to the deployment tool Ceph-deploy of Ceph, so that the Ceph identifies and deploys the homemade operating system on the homemade operating system, thereby adapting the Ceph to the homemade operating system running on the LoongArch architecture processor platform.
The LoongArch architecture processor may employ a LoongArch 5000 and series LoongArch instruction set CPUs above. The homemade operating system can be a homemade kylin server operating system. When the homemade kylin server operating system is adopted, the steps S1, S2 and S3 can be executed first, and then the homemade kylin server operating system tag is added to Ceph-deploy, so that Ceph can be adapted to, deployed and compiled to run with the homemade kylin server operating system of the longarch architecture processor platform.
The method for adapting the Ceph to the domestic operating system based on the LoongArch architecture processor platform can automatically identify the architecture and match code files on the domestic operating system, and completely compile, run basic service and deploy a Ceph cluster. The method expands the branches of the LoongArch architecture on the basis of the Ceph original code, does not influence any structure of the original code, and has high expandability.
While the foregoing specification illustrates and describes embodiments of the present invention, it is to be understood that the invention is not limited to the precise form herein, and that various other embodiments may be devised without departing from the scope thereof, and that various changes and modifications may be effected by those skilled in the art without departing from the scope of the claims that follow.
