kernel/linux.git/tools/sched, branch v6.18.21Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v6.18.212025-07-14T08:59:33+00:00tools/sched: Add dl_bw_dump.py for printing bandwidth accounting info2025-07-14T08:59:33+00:00Juri Lellijuri.lelli@redhat.com2025-06-27T11:51:18+00:00urn:sha1:634c24068abf8f325e520e663250e4a32a95ea0e
dl_rq bandwidth accounting information is crucial for the correct
functioning of SCHED_DEADLINE.
Add a drgn script for accessing that information at runtime, so that
it's easier to check and debug issues related to it.

tools/sched: Add root_domains_dump.py which dumps root domains info2025-07-14T08:59:33+00:00Juri Lellijuri.lelli@redhat.com2025-06-27T11:51:17+00:00urn:sha1:9fdb12c88e9ba75e2d831fb397dd27f03a534968
Root domains information is somewhat hard to access at runtime. Even
with sched_debug and sched_verbose, such information is only printed
on kernel console when domains are modified.
Add a simple drgn script to more easily retrieve root domains
information at runtime.
Since tools/sched is a new directory, add it to MAINTAINERS as well.
