Note that this list also contains individuals with no obvious affiliation to an organisation. These are grouped under :
- 1) Unaffiliated Individuals (of which there are 23). Note that some of these may be affiliated to an organization. We just may not know.
- 2) This figure contains the removal of the Xen Itanium port (47980 lines of code), which is skewing this figure heavily. Without this removal, the Citrix contribution is only 39151 lines of code
Breakdown by Organisations contributing 1% or more
The following list shows Organizations which contributed either more than 1% in terms of code or changesets. Note that we showed the removal of the toolstack support of the IA64 port (performed by a Ian Campbell, a committer employed by Citrix), whereas in Xen 4.2 the hypervisor portion of the IA64 port was we removed by Jan Beulich (a committer employed by Suse).
This image contains groups of people or organisations:
- Other : a bucket for commercial organizations contributing under 1%
- Individual : a bucket 23 unaffiliated individuals (or whose affiliation is unknown) who contributing under 1%
- Academia : a bucket for Universities contributing under 1%
