Subject: [ANNOUNCEMENT] CFP: Real-time and Scheduling MC at LPC
Date: Tue, 20 Jun 2023 19:13:04 +0200 [thread overview]
Message-ID: <d6113bec-6591-2efc-2255-66867e5db899@kernel.org> (raw)
The real-time and scheduling micro-conference joins these two
intrinsically connected communities to discuss the next steps together.
Over the past decade, many parts of PREEMPT_RT have been included
in the official Linux codebase. Examples include real-time mutexes,
high-resolution timers, lockdep, ftrace, RCU_PREEMPT, threaded interrupt
handlers, and more. The number of patches that need integration has been
significantly reduced, and the rest is mature enough to make their way
into mainline Linux.
The scheduler is at the core of Linux performance. With different
topologies and workloads, giving the user the best experience possible is
challenging, from low latency to high throughput and from small
power-constrained devices to HPC, where CPU isolation is critical.
The following accomplishments have been made as a result of last
year’s micro-conference:
- Progress on rtla/osnoise to support any workload [1]
- Progress on adding tracepoints for IPI [2]
- Improvements in RCU to reduce noise
- Progress on the latency-nice patch set [3]
Ideas of topics to be discussed include (but are not limited to):
- Improve responsiveness for CFS tasks - e.g., latency-nice patch
- The new EEVDF scheduler proposal [4]
- Impact of new topology on CFS including hybrid or heterogeneous system
- Taking into account task profile with IPCC or uclamp
- Improvements in CPU Isolation
- The status of PREEMPT_RT
- Locking improvements - e.g., proxy execution [5]
- Improvements on SCHED_DEADLINE
- Tooling for debugging scheduling and real-time
It is fine if you have a new topic that is not on the list.
People are encouraged to submit any topic related to real-time
and scheduling.
Please consider that the goal is to discuss open problems, preferably
with patch set submissions already in discussion on LKML. The
presentations are very short, and the main portion of the time should
be given to the debate - thus, the importance of having an
open and relevant problem, with people in the community engaged
in the solution.
Submissions are made via LPC submission systems, selecting *Track Real-time
and Scheduling MC*
Please, forward this email for people interested on this subject (it not easy to
build the Cc: list for this email without forgetting important people :-))!
