I'm glad you're interested in taking care of the machines. TBH, I was even considering disabling them for now, since at least one machine has been offline for a long time, and the other has this giant queue. I'm not sure if you're going to use the same machines as Yao was using (IIRC, he was using machines from the GCC Compile Farm). >> Then, I think the best approach for the SVE builds would be to manually >> download a Linux kernel, put the sources somewhere, and then I could >> configure a specific builder to build GDB with the SVE headers. >>=20 > > Given the current queues, I suspect we=E2=80=99d not get this done before= the 8.2 > branch.

If you're planning to continue using the GCC Farm machine, then I think the best option would be to contact the admins and ask them. Feel free to contact me in private if you need help sorting this out.
