* Merge branch 'wip-edf-wm' into wip-semi-partAndrea Bastoni2010-09-22
|\ | | | | | | | | | | | | | | | | | | | | | | | | Merging library branches for EDF-fm, EDF-WM, and NPS-F scheduling algorithms. This version of the library will compile against litmus2010 with all plugins merged (wip-semi-part). Conflicts: SConstruct include/litmus.h src/litmus.c

| | * avoid inconsistencies in the task parametersBjoern B. Brandenburg2010-09-22
| | | | | | | | | | | | | | | Floating point conversions introduce rounding errors. Fix-up the total execution cost as the sum of individual budgets.

| * Add rt_launch_edfwm launcherAndrea Bastoni2010-09-22
| | | | | | | | | | As rtspin_edfwm rt_launch_edfwm reads each task information from a text file (same format as rtspin_edfwm).
| * Add rtspin_edffm launcher functionAndrea Bastoni2010-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It reads the parameter for a task from a text file. The format is: - <task-id, wcet, period, phase, firstcpu, number of slices> (for task parameters). - <task-id, cpu, deadline, wcet, phase> (for slices). Example: 15 2.96343109764 10 0 3 7 15 3 1.428571 1.175260 0.000000 15 7 2.857143 0.700065 1.428571 15 2 4.285714 0.504732 2.857143 15 0 5.714286 0.279637 4.285714 15 1 7.142857 0.185294 5.714286 15 4 8.571429 0.065379 7.142857 15 6 10.000000 0.053062 8.571429
* | [NPS-F] Adapt to new add_server() API and fix parameters orderAndrea Bastoni2010-07-23
| | | | | | | | | | - comply with new add_server() API - fix wrong order in parameters for rt_launch_npsf.c
* | [NPS-F] Rework add_server() APIAndrea Bastoni2010-06-25
| | | | | | | | | | | | | | - add_server() syscall takes a npsf_id and an array of struct 'npsf_budgets'. Each entry of the array is a tuple (cpu, budget) that defines the budget reserved for the server 'npsf_id' on the cpu 'cpu'. - Input data is read from a file with struture: "npsf_id cpu budget-us"
* | [NPS-F] Add rt_launch version for NPS-F algoAndrea Bastoni2010-06-24
| |
* | [NPS-F] Add rtspin and utility to add notional processorsAndrea Bastoni2010-06-24
| | | | | | | | | | | | - add syscall to add notional processors (servers) - add rtspin_npsf program to run on specified (npsf_id, cpu) - add npsf_add_server as wrapper on the syscall
* | Adapt parameters order in *_edffm programs to new formatAndrea Bastoni2010-06-18
| | | | | | | | | | - "num1 denom1 cpu1 num2 denom2 cpu2" instead of "num1 denom1 num2 denom2 cpu1 cpu2"

* Support budget enforcement policies. Allows tasks to specifyGlenn Elliott2010-05-20
| | | | | | | | how their execution budgets should be enforced: NO_ENFORCEMENT, QUANTUM_ENFORCEMENT, and PRECISE_ENFORCEMENT (unsupported). NOTE: Users of NO_ENFORCEMENT must call sleep_next_period() at the end of every job to signal to the kernel that its job is complete.
* Add -v (verbose) switch to rtspin.Bjoern B. Brandenburg2010-03-10
| | | | | Can be used to dump the delay loop that rtspin is using.

* Remove old tests.Bjoern B. Brandenburg2009-09-11
| | | | | | People got confused how to use them. They were never meant to be useful to outside developers. So, just get rid of them now.
* release: add -w and -f optionsBjoern B. Brandenburg2009-05-02

| | | | this finally appears to work reasonably on Flare
* auto-configure spin loop in rtspinBjoern B. Brandenburg2009-03-25
| | | | | Don't just blindly overrun the budget. Instead, try to measure a spin loop and hope that we get good results.
* add system call overhead measurement programBjoern B. Brandenburg2009-03-02
| | | | | Run this tool (and a background workload) to measure system call overheads.
