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 the core of Linux performance. With different topologies and
workloads, it is not an easy task to give the user the best experience possible,
from low latency to high throughput, and from small power-constrained devices to
HPC.
In the last years, the real-time and scheduling microconferences helped in the
The Real-time Linux Analysis tool merge [1], progress on the full mainline merge
of the PREEMPT_RT, core scheduling merge and to promote the progress in the
latency nice scheduling feature [3].
If you are interested in participating in this microconference and have topics
to propose, please use the LPC CfP process [4], and select "Real-time and
Scheduling" for the "Track".
A non exhaustive list of potential topics is:
- How to scale PREEMPT_RT for very-large systems
- Improve overall system partitioning for real-time HPC workloads
- Latency nice scheduling feature
- Better support/heuristics for new processors
- New tools for PREEMPT_RT analysis.
- How do we teach the rest of the kernel developers how not to break
PREEMPT_RT?
- The usage of PREEMPT_RT on safety-critical systems: what do we need to do?
- The merge's status, and how can we resolve the last issues that block the
merge.
- What’s next?
The submission deadline is June 30.
Come and join us in the discussion, we hope to see you there!
