The final contact point for Linux 2.6+ - submissions is Andrew Morton. - -What Criteria Determine Acceptance ----------------------------------- - -Licensing: - The code must be released to us under the - GNU General Public License. If you wish the driver to be - useful to other communities such as BSD you may release - under multiple licenses. If you choose to release under - licenses other than the GPL, you should include your - rationale for your license choices in your cover letter. - See accepted licenses at include/linux/module.h - -Copyright: - The copyright owner must agree to use of GPL. - It's best if the submitter and copyright owner - are the same person/entity. If not, the name of - the person/entity authorizing use of GPL should be - listed in case it's necessary to verify the will of - the copyright owner. - -Interfaces: - If your driver uses existing interfaces and behaves like - other drivers in the same class it will be much more likely - to be accepted than if it invents gratuitous new ones. - If you need to implement a common API over Linux and NT - drivers do it in userspace. - -Code: - Please use the Linux style of code formatting as documented - in :ref:`Documentation/process/coding-style.rst <codingStyle>`. - If you have sections of code - that need to be in other formats, for example because they - are shared with a windows driver kit and you want to - maintain them just once separate them out nicely and note - this fact. - -Portability: - Pointers are not always 32bits, not all computers are little - endian, people do not all have floating point and you - shouldn't use inline x86 assembler in your driver without - careful thought. Pure x86 drivers generally are not popular. - If you only have x86 hardware it is hard to test portability - but it is easy to make sure the code can easily be made - portable. - -Clarity: - It helps if anyone can see how to fix the driver. It helps - you because you get patches not bug reports. If you submit a - driver that intentionally obfuscates how the hardware works - it will go in the bitbucket. - -PM support: - Since Linux is used on many portable and desktop systems, your - driver is likely to be used on such a system and therefore it - should support basic power management by implementing, if - necessary, the .suspend and .resume methods used during the - system-wide suspend and resume transitions. You should verify - that your driver correctly handles the suspend and resume, but - if you are unable to ensure that, please at least define the - .suspend method returning the -ENOSYS ("Function not - implemented") error. You should also try to make sure that your - driver uses as little power as possible when it's not doing - anything. For the driver testing instructions see - Documentation/power/drivers-testing.rst and for a relatively - complete overview of the power management issues related to - drivers see :ref:`Documentation/driver-api/pm/devices.rst <driverapi_pm_devices>`. - -Control: - In general if there is active maintenance of a driver by - the author then patches will be redirected to them unless - they are totally obvious and without need of checking. - If you want to be the contact and update point for the - driver it is a good idea to state this in the comments, - and include an entry in MAINTAINERS for your driver. - -What Criteria Do Not Determine Acceptance ------------------------------------------ - -Vendor: - Being the hardware vendor and maintaining the driver is - often a good thing.

Ideally work with the - existing driver author to build a single perfect driver. - -Author: - It doesn't matter if a large Linux company wrote the driver, - or you did.
