Mark Weinem offered a summary of NetBSD's six 2007 Summer of Code development projects. The projects included: the Automated Testing Framework, "the goal of the ATF project was to develop a testing framework to easily define test cases and run them in a completely automated way"; porting ZFS, "the primary goal of this project was to port volume emulation (ZVOL) functionality in order to mount ZFS file systems"; QoS framework for NetBSD's virtual memory system, "for delay sensitive systems such as streaming multimedia servers and back-end database systems, servicing the reader processes in a timely fashion is more important than the servicing the writers"; kernel file systems in userspace, as a result of the project, "almost all NetBSD kernel file systems can be compiled, mounted and run in userspace"; and hardware monitoring, "the aim of this project was to develop a kernel event notification framework to notify userland of hardware changes e.g. a new USB device being added". Mark added:

"NetBSD has been involved in the Google Summer of Code since its conception in 2005. This year we were glad to once again have the oppertunity to introduce six students to our operating system, to Open Source software development and get them sponsored by Google to work on projects defined by the NetBSD developers."

"The following patches implement a more generalized infrastructure (than latency.c) for connecting drivers and subsystem's that could implement power performance optimizations with the data needed to implement such policies," began Mark Gross, describing his Quality of Service power management patchset. He added, "these patches are following up on the discussions and presentations at the power management summit last summer." Mark continued:

"The idea is that from an abstract point of view how much to throttle hardware can be expressed as a function of QoS types of parameters; Latency, throughput, and idle time outs.

"The qos_parameter patch is intended to put into place the registration and notification infrastructure for enabling QoS based policy choices by drivers, where constraints on throttling are communicated through the qos_params module."
