resources: Update gapbs' gem5 system configs to run newer Linux kernel

The current system config of gapbs runs into kernel panic due to SWIOTLB.

This commit replaces gapbs system config by boot-exit system config,
which is known to work with most of currently supported Linux kernels.

gem5 Resources

This repository contains the sources needed to compile the gem5 resources. The compiled resources are found in the gem5 resources bucket, http://dist.gem5.org/dist. Though these resources are not needed to compile or run gem5, they may be required to execute some gem5 tests or may be useful when carrying out specific simulations.

The following sections outline our versioning policy, how to make changes to this repository, and describe each resource and how they may be built.

Versioning

We ensure that for each version of the gem5 source there is a corresponding version of the gem5-resources, with the assumption that version X of the gem5 source will be used with version X of the gem5-resources. The gem5-resources repository contains two branches, develop and stable. The stable branch's HEAD points towards the latest gem5 resources release, which will be the same version id as the that of the latest gem5 source. E.g., if the latest release of gem5 is v20.2.0.0, then the latest release of gem5-resources will be v20.2.0.0, with the HEAD of its stable branch tagged as v20.2.0.0. Previous versions will be tagged within the stable branch. Past versions gem5-resources can thereby be checked out with git checkout <VERSION>. A complete list of versions can be found with git tag. The develop branch contains code under development and will be merged into the stable branch, then tagged, as part of the next release of gem5. More information on gem5 release procedures can be found here. Any release procedures related to the gem5 source can be assumed to be applicable to gem5-resources.

The compiled resources for gem5 can be found under http://dist.gem5.org/dist/{VERSION}. E.g. compiled resources for gem5 v20.2 are under http://dist.gem5.org/dist/v20-1 and are compiled from gem5-resources v20.2. http://dist.gem5.org/dist/develop is kept in sync with the develop branch, and therefore should not be depended upon for stable, regular usage.

Note: Resource files for gem5 v19.0.0.0, our legacy release, can be found under http://dist.gem5.org/dist/current.

Making Changes

Changes to this repository are made to the develop branch via our Gerrit code review system. Therefore, to make changes, first clone the repository checkout the develop branch:

git clone https://gem5.googlesource.com/public/gem5-resources
git checkout --track origin/develop

Then make changes and commit. When ready, push to Gerrit with:

git push origin HEAD:refs/for/develop

The change will then be reviewed via our Gerrit code review system. Once fully accepted and merged into the gem5-resources repository, please contact Bobby R. Bruce bbruce@ucdavis.edu to have the compiled sources uploaded to the gem5 resources bucket.

Resource: RISCV Tests

The RISCV Tests soruce can be found in the src/riscv-tests directory. More information about these tests can be found in src/riscv-tests/README.md.

RISCV Tests Origins

The RISCV Tests in this repository were obtained from https://github.com/riscv/riscv-tests.git, revision 19bfdab48c2a6da4a2c67d5779757da7b073811d.

RISCV Tests Compilation

To compile the RISCV Tests the RISCV GNU Compiler must be installed.

Then, to compile:

cd src/riscv-tests
autoconf
./configure --prefix=/opt/riscv/target
make -C src/riscv-tests

This RISCV binaries can then be found within the src/riscv-tests/benchmarks directory.

Resource: simple

The simple resources are small binaries, often used to run quick tests and checks in gem5. Their bare-meltal

simple Compilation

Simple single source file per executable userland or baremetal examples.

The toplevel executables under src/simple can be built for any ISA that we have a cross compiler for. The current cross compilers supported are :

Examples that build only for some ISAs specific ones are present under src/simple/<ISA> subdirs, e.g. src/simple/aarch64/,

The ISA names are meant to match uname -m, e.g.:

  • aarch64
  • arm
  • riscv
  • x86_64
  • sparc64

You have to specify the path to the gem5 source code with GEM5_ROOT variable so that m5ops can be used from there. For example for a native build:

cd src/simple
make -j`nproc` GEM5_ROOT=../../../

The default of that variable is such that if you place this repository and the gem5 repository in the same directory:

./gem5/
./gem5-resources/

you can omit that variable and build just with:

make

After the building, the generated files are located under:

./out/<ISA>/

For example, some of the userland executables built on x86 are:

./out/x86_64/user/hello.out
./out/x86_64/user/x86_64/mwait.out

Or if you build for a different ISA:

make ISA=aarch64

some of the executables would be:

./out/aarch64/user/hello.out
./out/aarch64/user/aarch64/futex_ldxr_stxr.out

By default, only userland executables are built. You can build just the baremetal ones instead with:

make ISA=aarch64 bare

or both userland and baremetal with:

make ISA=aarch64 all

A sample baremetal executable generated by this is:

out/aarch64/bare/m5_exit.out

Only ISAs that have a corresponding src/simple/bootloader/ file can build for baremetal, e.g. src/simple/bootloader/aarch64.S.

Note that a some C source files can produce both a baremetal and an userland. For example m5_exit.c produces both:

out/aarch64/bare/m5_exit.out
out/aarch64/user/m5_exit.out

However, since the regular userland toolchain is used rather than a more specialized baremetal toolchain, the C standard library is not available. Therefore, only very few C examples can build for baremetal, notably the ones that use m5ops.

There are also examples that can only build for baremetal, e.g. aarch64/semihost_exit only builds for baremetal, as semihosting is not available on userland.

The simple directory is also able to generate squashfs images containing only a single userland executable at /sbin/init for any of the userland executables. This can be done with a command of type:

make ISA=aarch64 out/aarch64/squashfs/m5_exit.squashfs

Squashfs is a filesystem type that the Linux kernel understands natively, exactly like ext4, except that it is a bit more convenient to create, and write-only.

You can therefore give those squashfs images to gem5 exactly as you would give a normal ext4 raw image, by pointing to it for example with fs.py --disk-image=m5_exit.squashfs as shown at: https://www.gem5.org/documentation/general_docs/fullsystem/building_arm_kernel Linux will then run the given userland executable after Linux boots as the init program.

The initial motivation for this was to generate simple test images for Linux boot.

Since this is a less common use case, squashfs images are not currently generated by any single phony target all at once.
