Poulsbo is the codename given by Intel to its second-generation ultra mobile PC chipset.[1] It is a low-power chipset for mobile Internet devices used with Intel Atom microprocessors.[2]

Line-up[3]

Graphics core

The Poulsbo chipset contains a graphics core developed by Imagination Technologies. Intel has licensed the PowerVR SGX as a graphics core and the PowerVR VXD for H.264/MPEG-4 AVC playback. The video core is able to process 720p as well as 1080i resolutions.[9]

Linux support

Although several netbooks using the Poulsbo chipset are shipped with some distribution of Linux (notably the Sony Vaio P and Dell Inspiron Mini 12, among others), Poulsbo's graphics core GMA 500 is currently not well supported by Intel for the Linux platform.

However there is a quite easy way to have the drivers work on any Debian-based distribution, thanks to the Ubuntu sources and packages, for the linux kernel 2.6.30 (with newer kernel it would need a little hacking but seems still possible while the sources are included). A detailed explanation is available here[10].

A proprietary driver was shipped with Dell's adaptation of Ubuntu 8.04.1 Netbook Remix, which provides 2D hardware acceleration (although users reported serious stability issues[11]) under Linux kernel 2.6.24. A work in progress free driver is currently available, however the proprietary driver does not work with current Linux kernels and current versions of X.[12] Work is under way to provide at least 2D support in current Linux kernels,[13] although this will still rely on proprietary binary code for the 3D part of the driver. The current[14] status of this driver runs on Fedora 10 and allows for 2D. 3D acceleration, however, is still broken.

Fedora 11 has a working driver developed. Installation instructions at [1]

Starting with Mandriva 2010 Release Candidate 2, Poulsbo drivers are now fully supported out of the box when you use One isos. Hardware will be automatically detected and configured using XFdrake. As it needs non-free firmware, this could not be included in Free isos. [2]
