* Integrate preemption state machine with Linux schedulerBjoern Brandenburg2014-06-07
| | | | Track when a processor is going to schedule "soon".
* Record LITMUS^RT timestamp in ftrace recordsGlenn Elliott2014-06-07
| | | | | Patch updates ftrace.h to record a litmus_clock() time stamp in ftrace records.
* Move trace point definition to litmus/litmus.cBjoern Brandenburg2014-06-07
| | | | | | | | If !CONFIG_SCHED_TASK_TRACE, but CONFIG_SCHED_LITMUS_TRACEPOINT, then we still need to define the tracepoint structures. This patch should be integrated with the earlier sched_task_trace.c patches during one of the next major rebasing efforts.
* Add LITMUS^RT syscalls for x86Bjoern Brandenburg2014-06-07
|
* Add LITMUS^RT syscalls for ARMBjoern Brandenburg2014-06-07
|
* Add LITMUS^RT core implementationBjoern Brandenburg2014-06-07
| | | | | | | | | | | | | This patch adds the core of LITMUS^RT: - library functionality (heaps, rt_domain, prioritization, etc.) - budget enforcement logic - job management - system call backends - virtual devices (control page, etc.) - scheduler plugin API (and dummy plugin) This code compiles, but is not yet integrated with the rest of Linux.
* Export num_cache_leaves in asm/processor.hBjoern Brandenburg2014-06-07
| | | | This is required to make litmus/affinity.c compile.
* Add object descriptor table to Linux's task_structBjoern Brandenburg2014-06-07
| | | | | This table is similar to a file descriptor table. It keeps track of which "objects" (locks) a real-time task holds a handle to.
* Add tracepoint supportBjoern Brandenburg2014-06-07
| | | | | | | This patch integrates LITMUS^RT's sched_trace_XXX() macros with Linux's notion of tracepoints. This is useful to visualize schedules in kernel shark and similar tools. Historically, LITMUS^RT's sched_trace predates Linux's tracepoint infrastructure.
* Add schedule tracing supportBjoern Brandenburg2014-06-07
| | | | | | This patch introduces the sched_trace infrastructure, which in principle allows tracing the generated schedule. However, this patch does not yet integrate the callbacks with the kernel.
* Feather-Trace: write interrupt counts to control pageBjoern Brandenburg2014-06-07
| | | | | This patch exports the interrupt counter to userspace via the control page.
* Feather-Trace: use proper definition of is_realtime()Bjoern Brandenburg2014-06-07
| | | | Remove dummy implementation of is_realtime() in trace.c.
* Introduce main LITMUS^RT headerBjoern Brandenburg2014-06-07
| | | | | This patch adds a basic litmus/litmus.h, which is required for basic LITMUS^RT infrastructure to compile.
* Extend task_struct with rt_paramBjoern Brandenburg2014-06-07
| | | | This patch adds the PCB extensions required for LITMUS^RT.
* Add hrtimer_start_on() supportFelipe Cerqueira2014-06-07
| | | | | | This patch adds hrtimer_start_on(), which allows arming timers on remote CPUs. This is needed to avoided timer interrupts on "shielded" CPUs and is also useful for implementing semi-partitioned schedulers.
* Add TRACE() debug tracing supportBjoern Brandenburg2014-06-07
| | | | This patch adds the infrastructure for the TRACE() debug macro.
* Add object list to inodesBjoern Brandenburg2014-06-07
| | | | | | | This patch adds a list of arbitrary objects to inodes. This is used by Linux's locking API to attach lock objects to inodes (which represent namespaces in Linux's locking API).
* Export x86 cache topologyFelipe Cerqueira2014-06-07
| | | | | This patch adds get_shared_cpu_map(), which allows the caller to infer which CPUs share a cache at a given level.
* Add SCHED, SCHED2, TICK, and CXS overhead tracepointsBjoern Brandenburg2014-06-07
| | | | | | | This patch integrates the overhead tracepoints into the Linux scheduler that are compatible with plain vanilla Linux (i.e., not specific to LITMUS^RT plugins). This can be used to measure the overheads of an otherwise unmodified kernel.
* Integrate ft_irq_fired() with LinuxBjoern Brandenburg2014-06-07
| | | | | This patch hooks up Feather-Trace's ft_irq_fired() handler with Linux's interrupt handling infrastructure.
* Feather-Trace: add LITMUS^RT overhead tracing infrastructureBjoern Brandenburg2014-06-07
| | | | | This patch adds the main infrastructure for tracing overheads in LITMUS^RT. It does not yet introduce any tracepoints into the kernel.
* Feather-Trace: add generic ftdev device driverBjoern Brandenburg2014-06-02
| | | | | This patch adds the ftdev device driver, which is used to export samples collected with Feather-Trace to userspace.
* Feather-Trace: add x86 binary rewriting implementationBjoern Brandenburg2014-06-02
| | | | | This patch adds the x86-specific implementation of Feather-Trace triggers that works by rewriting jump instructions.
* Feather-Trace: add platform independent implementationBjoern Brandenburg2014-06-02
| | | | | This patch adds the simple fallback implementation and creates dummy hooks in the x86 and ARM Kconfig files.
* Add LITMUS^RT directoryBjoern Brandenburg2014-06-02
| | | | Hookup litmus/ with kernel and add extra version.
