Lua

LuaJIT is open source software and depends on your contributions! This may be in the form of bug reports, bug fixes and patches — see the status page for details. Another option is to financially support the project through corporate sponsorship.

How to Become a Sponsor

Sponsorship is open to all companies worldwide. For various legal and administrative reasons I cannot accept funds from individuals. The basic idea is that your company finances the work on a particular feature of LuaJIT. Everyone gets a proper invoice, tax receipt, Rechnung or whatever it's called in your country. This can usually be deducted as a business expense if it's directly related to the needs of your business (but check with your tax advisor first).

In exchange for sponsoring the work on a feature, it's incorporated into LuaJIT and is available as open source under the same liberal license. Thus you get your favorite missing feature and everyone benefits, too. Some features need a lot of work and probably cannot be financed by one company alone (e.g. the x64 port). The intention of this page is to gather all interested parties to contribute to a sponsorship program.

To arrange for contracting me to work on a particular feature, please contact me under my business address:

Sponsorship for the PowerPC port of LuaJIT

A corporate sponsor who wishes to remain anonymous, has sponsored the port of LuaJIT to PowerPC in August 2010. In the first phase this will be a port of the hand-optimized LuaJIT interpreter to the FreeScale e500v2 cores, which are popular in embedded applications.

Work on the port is still in progress — you can follow it in the git repository.

Please note that the e500v2 has a different FPU than most other PowerPC CPUs. This port will not run on other PPC-based machines. A port of the JIT compiler and/or a port to other PowerPC CPUs may follow later.

Sponsorship for the x64 port of LuaJIT

The goal of this sponsorship campaign was to raise € 20,000 for the x64 port of LuaJIT 2.0. To jump-start sponsorship of LuaJIT, Athena Capital Research has provided an initial contribution of € 5,000 in December 2009.

As part of their commitment to the open source community, Athena Capital Research has offered to provide up to € 7,000 of matching funds. All funds offered through corporate sponsorship have been matched one-to-one. Other funds have been matched two-to-one.

The x64 sponsorship goal was reached in January 2010 and a total of € 20,167 was raised! The x64 port is complete by now and available from the download page.

Many thanks to all sponsors for supporting LuaJIT!
