Xen project Mailing List

Issue suggested by Simon

In Unikraft - whenever compiler flags are changed due to an addition of a library or something else according to the build rules, the make command doesn't force recompilation of those files affected by the flag change unless the files are altered too. The only way out is to "make clean" and "make" again all the files which can be redundantly time-consuming.

Solution
One way is to create flag files for objects and add those as their dependency in the Makefile.

Apart from this, I'm wondering if rules are passed on to the Makefile and changes are depicted in the Makefile itself, can we add Makefile as the dependency of objects to solve this issue?

Thank you.

Hi Lars,

I'm already on #unikraft with the registered username - kanik.
My timezone is UTC+5:30h and I can be available for a chat at any time of the day post noon usually.

I have subscribed to the mailing lists and gone through the documentation at https://wiki.xenproject.org/wiki/Submitting_Xen_Project_Patches#How_to_Generate.2C_and_Submit_a_Xen_Project_Patch_to_MiniOS_and_Unikraft thoroughly.

Also, I have completed the first task you suggested, that is, to build the hello world app. Below is the screenshot of it running on my system.

Keeping my skill set and experience in mind, I'm mostly interested in and suitable for projects - Enhanced Profiling and Tracing Support for Unikraft and High-level Language Support with Unikraft.

I was having my exams this week and hence, couldn't start with much force but now, I'm all pumped up to make significant contributions. :D
If there are not many people already working on it, please, let me know the next steps to begin contributing.

Thank you!

I believe that there will be extra checks later in the application process, which may require letters from your University. We had one case, where an applicant did a small project, but we were not allowed to accept her due to time requirements.

For the ARM project, it would be good to get familiar with Xen on ARM,
to learn how to build it:

https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions#Building_Xen_on_ARM

and use QEMU to emulate an ARM board to run Xen on it, for testing and
development:

https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/qemu-system-aarch64

Feel free to ask any questions!

I'm currently pursuing a course in Operating Systems and hence, have been gaining knowledge in kernel programming by short assignments like the implementation of a system call. I'm familiar with assembly programming in MIPS, ARM and x86 as well.
