Linux Kernel on Ubuntu Ports Architectures

Following Hardy, the linux package was subdivided into three seperate packages, linux, linux-lpia, and linux-ports. linux-ports is in charge of of building kernels for the Ubuntu ports expect for lpia, as well as the linux-image-386 kernel varient. This page tracks the status of the kernel

Current Versions

• Intrepid: 2.6.24-19 (ubuntu/ubuntu-intrepid-ports.git)
• Jaunty: 2.6.27.4

Jaunty Release Goals

• Releasing with 2.6.28 or .29
• LiveCD support on all architectures expect HPPA

Current Issues - General

• The ports tree has not been rebased against Linus's tree in an extremely long period of time, and rebasing attempts have proved difficult to impossible. A fresh branch of 2.6.27.2 has been made, and patches are being manually merged from intrepid-ports
• We need tests for architecture specific port kernels
• Useful drivers and features (i.e. AuFS/AppArmour) has been cherry picked out of the main tree into the ports tree
• WACOM tablet support causes a FTBFS. Removed for now, but this should be considered release criticia I think

Architecture Build Status

• i386-386: Currently builds and actively tested
• PowerPC: Currently builds and actively tested
• IA-64: Currently builds; needs image testing
• SPARC: Needs Porting
• HPPA: Currently builds; needs image testing

Architecture Specific Current Issues

PowerPC - 64-bit SMP

• PlayStation 3 patches from intrepid kernel need to be cherry-picked or ported.

IA-64 - All (2.6.27)

• Needs its config files sanity checked by someone more experienced with the hardware
• AuFS needs porting
• udebs are miserably broken since most of the modules requested are not built. A lot of the udebs are excluded for ia64 so the kernel builds, but d-i will need a good amount of work

SPARC - All (2.6.27)

• LIRC needs porting if it is desirable

HPPA - All (2.6.27)

• Needs config files sanity checked
• AuFS, SquashFS, and LIRC need porting.
