| | | | | | | | | | | | Mixed criticality implementation, not including slack stealing. In addition, Level A is still P-EDF instead of cyclic executive.

| * fixup: litmus.h is no longer implicitly includedBjoern B. Brandenburg2010-10-23
| | | | | | | | | | | | | | Some change in .36 caused litmus.h to be no longer included in litmus_proc.c, which consequently caused a build error. (This commit should be squashed before being merged into master.)
| * C-EDF: move /proc/litmus/cluster_cache to /proc/litmus/plugins/C-EDF/clusterBjoern B. Brandenburg2010-10-23
| | | | | | | | | | | | | | Make use of the new per-plugin proc file infrastructure to avoid littering the global namespace. While at it, also move all the relevant bits to sched_cedf.c. In the future, each plugin's parameters should be handled in the respective plugin file.

* | Pfair: remove sporadic_release flagBjoern B. Brandenburg2011-02-01
| | | | | | | | | | Instead of having an extra flag, Pfair should just infer sporadic release based on deadlines like other plugins, too.
* | Pfair: support clustered schedulingBjoern B. Brandenburg2011-02-01
| | | | | | | | | | | | | | Just like C-EDF is a global scheduler that is split across several clusters, Pfair can be applied on a per-cluster basis. This patch changes the Pfair implementation to enable clustering based on the recently added generic clustering support.
* | Litmus core: add generic clustering supportBjoern B. Brandenburg2011-02-01
| | | | | | | | | | Inspired by the existing C-EDF code, this generic version will build clusters of CPUs based on a given cache level.
* | Litmus core: extract userspace interface from C-EDFBjoern B. Brandenburg2011-02-01
| | | | | | | | | | Make the cluster size configuration in C-EDF generic so that it can be used by other clustered schedulers.
* | Feather-Trace: rename locking trace pointsBjoern B. Brandenburg2011-02-01
| | | | | | | | | | Since we don't expect to trace more than one lock type at a time, having protocol-specific trace points is not required.
* | fdso: pass userpsace config argument to object constructorBjoern B. Brandenburg2011-02-01
| | | | | | | | | | | | | | | | | | | | | | | | As Glenn pointed out, it is useful for some protocols (e.g., k-exclusion protocols) to know the userspace configuration at object creation time. This patch changes the fdso API to pass the parameter to the object constructor, which is then in turn passed to the lock allocater. The return code from the lock allocater is passed to userspace in return. This also fixes some null pointer dereferences in the FDSO code found by the test suite in liblitmus.
* | GSN-EDF: re-implement FMLP supportBjoern B. Brandenburg2011-02-01
| | | | | | | | This introduces the global FMLP based on the generic locking layer.
* | PSN-EDF: re-implement FMLP supportBjoern B. Brandenburg2011-02-01
| | | | | | | | | | Implement the partitioned FMLP with priority boosting based on the generic lock API.
* | EDF: support priority boostingBjoern B. Brandenburg2011-02-01
| | | | | | | | While we are at it, simplify edf_higher_prio() a bit.
* | FMLP: remove old implementationBjoern B. Brandenburg2011-02-01
| |
* | SRP: port to new generic locking APIBjoern B. Brandenburg2011-02-01
| | | | | | | | | | This re-enables SRP support under PSN-EDF and demonstrates how the new locking API should be used.
* | Litmus core: replace FMLP & SRP system calls with generic syscallsBjoern B. Brandenburg2011-02-01
| | | | | | | | | | This renders the FMLP and SRP unfunctional until they are ported to the new locking API.
* | Litmus core: add generic locking APIBjoern B. Brandenburg2011-02-01
| | | | | | | | | | Provide a unified userspace interface for plugin-specific locking protocols.
* | Litmus core: change plugin locking interface to generic 'allocate_lock()'Bjoern B. Brandenburg2011-02-01
| | | | | | | | | | | | | | | | | | As the number of supported locking protocols is expected to rise, hard-coding things like priority inheritance in the plugin interface doesn't scale. Instead, use a new generic lock-ops approach. With this approach, each plugin can define its own protocol implementation (or use a generic one), and plugins can support multiple protocols without having to change the plugin interface for each protocol.
* | fdso: supply object type to constructor and destructor methodsBjoern B. Brandenburg2011-02-01
| | | | | | | | Passing the object type explicitly will enable generic lock constructors.
