If you do not need to update the Linux image, then go to ./linux-testvectors and
|
|
use tvCopier.py or tvLinker.sh to copy/link premade RAMs and testvectors from Tera.
|
|
The RAMs are needed for Wally to run the Linux code, and the testvectors are needed
|
|
to verify Wally is executing the code correctly.
|
|
|
|
If you instead wish to regenerate the RAMs and testvectors from a new Linux image,
|
|
you'll need to build the new Linux image, simulate it, and parse its output,
|
|
as described below.
|
|
|
|
* To build a new Linux image, Git clone the Buildroot repository to ./buildroot.
|
|
For reference, most recent commit made to the Buildroot repo was
|
|
as of last generating the image found on Tera:

|

|
Then link ./buildroot-config-src/main.config to ./buildroot/.config.
|
|
That config file will in turn point to the other config files in ./buildroot-config-src.
|
|
If you wish to modify the configs, then
|
|
1. Copy ./buildroot-config-src/linux.config to ./buildroot/output/build/linux-5.10.7/.config
|
|
2. Copy ./buildroot-config-src/busybox.config to ./buildroot/output/build/busybox-1.33.1/.config
|
|
3. Run "make menuconfig" "make linux-menuconfig" "make busybox-menuconfig" as needed.
|
|
4. Copy ./buildroot/output/build/linux-5.10.7/.config back to ./buildroot-config-src/linux.config
|
|
5. Copy ./buildroot/output/build/busybox-1.33.1/.config back to ./buildroot-config-src/busybox.config
|
|
(*** There may be a better way to do this, but do know that setting up main.config
|
|
to point to those two locations within the Buildroot repo results in interesting
|
|
".config is the same as .config" errors.)
|
|
Then finally you can run make. Note that it may be necessary to rerun make twice,
|
|
once when main.config asks for an "Image" output, and once when main.config
|
|
"vmlinux" output.
|
|
|
|
* To generate new RAMs and testvectors from a Linux image,
|
|
link ./buildroot-image-output to either your new image in ./buildroot/output/image
|
|
or the existing image at /courses/e190ax/buildroot/output/image on Tera.
|
|
Then run ./testvector-generation/logBuildrootMem.sh to generate RAMs.
|
|
Then run ./testvector-generation/logAllBuildroot.sh to generate testvectors.
