| [http://coccinelle.lip6.fr Coccinelle] is a program matching and transformation tool for C code that has been used extensively in contributing to the Linux kernel, for both code evolutions and bug fixes. Coccinelle is driven by specifications, known as semantic patches, that use a notation based on C code, and are this fairly easy to develop. Around 40 semantic patches are included with the Linux kernel source code, in scripts/coccinelle, and are used in the continuous testing service provided by Intel. | There will be no Coccinelle project in this round. Please feel free nevertheless to use Coccinelle in making cleanup patches. |

| The use of out of date APIs is confusing for people who need to understand the code, and requires the maintenance of excess code.

| The media subsystem has a kernel [http://lwn.net/Articles/607160/ driver] that emulates a V4L device in order to allow testing userspace applications without requiring hardware. We are, however, missing a driver that would emulate a [http://linuxtv.org/downloads/v4l-dvb-apis/media_controller.html Media Controller] device.

| The Linux wireless (WiFi) stack has migrated from the old obsolete WEXT API to the modern cfg80211/nl80211 API. The old WEXT API has been marked deprecated for years, but unfortunately a couple of drivers are still using it, making it impossible to remove the old code. | == IIO driver == ''Mentors:'': [:DanielBaluta:Daniel Baluta] & [:AlisonSchofield:Alison Schofield] |

| The goal of this project is to complete the conversion of the Orinoco wireless driver from using the WEXT API and make it a good cfg80211 citizen. | A driver allows applications to communicate and control hardware devices.

| == Full Dynamic Ticks == | The goal of this project is to write a driver for a sensor using the Industrial I/O interface. In the first part of the project you will get familiar with the hardware and the IIO subsystem then implement raw readings from the device. After upstreaming the code you will enhance the driver with advanced features such as support for buffered readings, power management and interrupts. The exact device will be decided when the internship starts. |

| CPUs have to be interrupted through periodic timers to initiate tasks such as update of CPUs'load and runtime of tasks, perform preemption of running tasks if necessary and load balancing to even out system wide load. But when CPUs are idle, none of these tasks is required to be performed as there is no load on them. So periodic timer interrupts can be stopped on idle CPUs. This improves power efficiency of the kernel to a good extent. Thus an infrastructure called "Tickless Idle" which disables periodic timer interrupts when CPUs are idle, was added to the 2.6.21 release of the Linux kernel. |
'''For IIO patches, be sure to send them to linux-iio@vger.kernel.org''' |
| Line 60: | Line 66: |
| However some users required that periodic timer interrupts be disabled even on CPUs running single tasks. Typically high performance workloads (HPC) and real time tasks are performance critical and require to be run undisturbed as far as possible. For the benefit of such tasks, the Full Dynamic Ticks infrastructure was added to the 3.10 release of the Linux kernel. The goal of Full Dynamic Ticks is to enable CPUs to run in tickless mode as long as they are running single tasks. As a consequence it manages to isolate such CPUs to run performance critical user tasks without interruptions from the kernel. Over the months much effort has gone into making this stable. However there is more work to be done. |
== Documentation == ''Mentor:'': [:JonathanCorbet:Jonathan Corbet] |
| Line 65: | Line 69: |
| The goal of this project is to tackle specific issues that are currently in way of running CPUs in Full Dynamic Tick mode effectively. | After many years of relative neglect, we are working to improve the kernel's documentation; this includes [https://lwn.net/Articles/692704/ a transition to the Sphinx formatting system.] There are a number of potential projects associated with this transition, ranging from the conversion of existing documents into the ReStructured Text format and integrating them into the manual through to improving the Python/Perl-based document build system, adding kerneldoc comments to the source, and writing entirely new documents. |
| Line 67: | Line 71: |
| == IIO dummy driver == | If you want to work in this area, there are a number of things that can be done for the application process, starting with simple typo fixes in the documentation tree. Converting simple text documents to RST is a relatively straightforward task, but contacting the mentor first is recommended, since some parts of the documentation tree are more amenable to this work in the short term than others. We would also love to see fixes for the large number of warnings that are currently emitted as part of the build process. |

| The Industrial I/O subsystem is intended to provide support for devices that in some sense are analog to digital or digital to analog converters. Some devices that fall in this category are: accelerometers, gyroscopes, light sensors, etc. Linux staging already holds a dummy IIO driver which is very useful as documentation on how to write a driver. Also it is very useful for testing user space code and rapidly prototyping new interfaces. The goal of this project is to move IIO dummy driver out of staging. The major challenge in order to make this ready is interrupt emulation. The way evgen module generates interrupts greatly restricts their use and is far from clean. There is also work on the device creation part. Current approach where we use a module parameter controlling how many instances are created it's pretty ugly. Last thing we need to add support for more devices, allowing userspace applications to do smoke testing without have the actual hardware. |

Please note that these three skills can be learned during the internship.
Some projects may have small tasks you can complete as part of the application process. Do not start on these tasks until after you complete the [:Outreachyfirstpatch:first patch tutorial] and Greg Kroah-Hartman has accepted at least ten of your cleanup patches and two of your patchsets. In order to ensure applicants aren't working on the same task, we need your help in coordinating who is working on what task.
