This patch series updates the scheduler documentation to add more topics wrt to scheduler overview. New sections are added to provide a brief overview of the kernel structs used by the scheduler, scheduler invocation, context switch and Capacity Aware Scheduling. Previous version of the patch was reviewed at: Link: https://lore.kernel.org/lkml/20200513134338.19688-2-John.Mathew@xxxxxxxxxx/ version 5: -Fix description error on CAS version 4: -Added section on Capacity-Aware Scheduling -Reworded CFS recently added features. -Removed vruntime description from scheduler structs -Added description of idle and stopper sched classses version 3: -Fix spelling, spacing and typo errors. version 2: - Remove :c:func: directive as it was redundant - Limit document width (line symbol count) to 75 - Replace dot file with ASCII art - Describe prepare_task_switch(), ASID use, kernel/user transtion, MIPS FPU affinity correctly - Add missing references to files - Removed internal APIs from scheduler API reference - Described rq struct member as kernel-doc comments - Replaced CFS history with CFS current status - Added documentation for sched_class fields - Refined explanation of context swtich functionality - Replace CFS history with recent changes - Added kernel-doc comments for struct rq John Mathew (3): docs: scheduler: Restructure scheduler documentation. docs: scheduler: Add scheduler overview documentation docs: scheduler: Add introduction to scheduler context-switch Documentation/scheduler/arch-specific.rst | 14 + Documentation/scheduler/cfs-overview.rst | 102 ++++++ Documentation/scheduler/context-switching.rst | 125 ++++++++ Documentation/scheduler/index.rst | 33 +- .../scheduler/mips-context-switch.rst | 89 ++++++ Documentation/scheduler/overview.rst | 293 ++++++++++++++++++ Documentation/scheduler/sched-cas.rst | 92 ++++++ .../scheduler/sched-data-structs.rst | 182 +++++++++++ Documentation/scheduler/sched-debugging.rst | 14 + Documentation/scheduler/sched-features.rst | 21 ++ Documentation/scheduler/scheduler-api.rst | 31 ++ .../scheduler/x86-context-switch.rst | 65 ++++ kernel/sched/core.c | 28 +- kernel/sched/sched.h | 169 +++++++++- 14 files changed, 1238 insertions(+), 20 deletions(-) create mode 100644 Documentation/scheduler/arch-specific.rst create mode 100644 Documentation/scheduler/cfs-overview.rst create mode 100644 Documentation/scheduler/context-switching.rst create mode 100644 Documentation/scheduler/mips-context-switch.rst create mode 100644 Documentation/scheduler/overview.rst create mode 100644 Documentation/scheduler/sched-cas.rst create mode 100644 Documentation/scheduler/sched-data-structs.rst create mode 100644 Documentation/scheduler/sched-debugging.rst create mode 100644 Documentation/scheduler/sched-features.rst create mode 100644 Documentation/scheduler/scheduler-api.rst create mode 100644 Documentation/scheduler/x86-context-switch.rst -- 2.17.1
