This might be a good project to present to Outreachy internship:
https://lists.gnu.org/archive/html/qemu-devel/2021-08/msg03970.html

 "QEMU will apply for the Outreachy December-March round. This
  internship program offers paid, full-time, remote work internships for
  contributing to open source. QEMU can act as an umbrella organization
  for KVM kernel projects."

Stefan, are we past the deadline for submission?

Regards,

Phil.

The Outreachy project idea deadline has been extended to September 29th.
QEMU contributors can submit project ideas they would like to mentor
here:
https://www.outreachy.org/communities/cfp/qemu/

Please take a look at this email for more details on designing Outreachy
projects:

Thanks,
Stefan

I skimmed over the source code in the afternoon, and indeed the 
encodings are textbook example of what should be auto-generated. However 
I didn't find the DSL syntax to be particularly palatable... maybe I was 
just reading a bit too quickly though.

As Song replied, Loongson Corporation should be very interested in 
testing their own offerings. This collaboration is exactly what we as a 
community strive for, and I'll happily review any code here or in 
loongarch-opcodes repo for that.
