Overview

desktop-maverick-easy-wayland-testing (0/0/1)

Make it easy to test the new Wayland display server by providing functional packages in Universe for Maverick. * Are there any wayland clients we could include other than the demos included in wayland git? * What do we need to do to make it easy to develop wayland clients? * What versions of libdrm, kernel, mesa does wayland require? Are these the versions we want for Maverick anyway?

Todo

desktop-maverick-xorg-gpu-freeze-reports (0/0/3)

* What can we do better for -intel GPU freezes? - These inevitably will have lots of duplicates, which reduced their usefulness in Lucid. What information do we need to match duplicates? Can we get the kernel to help? * Can we get the same sort of information via radeontool & avivotool for ati cards? * Can we get the same sort of information for nouveau? * How can we make mmiotracing as painless as possible for users, and as useful as possible for developers?

Todo

desktop-maverick-xorg-in-mm (0/0/2)

* Overview of X sessions at UDS * What version of xserver, mesa, libdrm shall we target for Maverick? * What versions of major drivers will be out, and what versions should we target? * Open mic: miscellaneous X business

Todo

foundations-m-grub2-boot-framebuffer (0/0/2)

GRUB2 supports programming a VBE mode in the boot loader and telling the kernel about it, causing the kernel to use a framebuffer at boot. With Linux 2.6.34, vesafb/efifb can hand over smoothly to a KMS driver, allowing us to assemble all of this into something very close to a flicker-free boot splash process.

Todo

foundations-m-uefi-support (0/0/1)

Support booting on systems using UEFI firmware.

Todo

kernel-maverick-arm-kernel-as-bootloader (0/0/2)

With a small block of basic hardware setup code in front of the kernel and kexec, the Linux kernel itself can be used as a full featured bootloader. The idea was inspired by talks in ELC this year, Linux without a boot loader - by Greg Ungerer, and Kexec - Ready for Embedded Linux? by Magnus Damm.

Todo

kernel-maverick-arm-single-zimage (0/0/4)

Unlike PC and x86-based platforms, where a single kernel image is normally the case to boot on all these platforms, there is usually one kernel image for a specific ARM SoC (imx51, dove, omap), or even one kernel image for a specific platform/board. This session is intended to discuss some of the challenges and general ideas toward a single zImage for a group of compatible ARM SoCs.

Todo

kernel-maverick-bios-test-automation (0/0/12)

It is desirable to be able automatically test specific BIOS functionality, such as suspend/resume, hibernate, wakeup, fan control, battery, C states etc.. to locate and hence be able to fix or workaround BIOS/ACPI errors. Also, it's desirable to add more kernel debug into hibernate/suspend code paths to help automatically to pin point BIOS errors. We propose a tool + kernel debug to do this automatic testing + diagnosis.

Todo

kernel-maverick-config-review (0/0/6)

Review of the kernel configuration for Maverick. This will concentrate on confirming the policy for various option type, as well as new options. For major new options, discussion and confirmation of the selection of each.

Todo

kernel-maverick-misc (1/0/11)

This is a catch all blueprint to capture and track any misc Kernel related work items. Each item doesn't warrant having an individual spec in itself, but still represent a task we'd like to complete.

Todo

kernel-maverick-new-kernel-on-lts (0/0/3)

Continue to Evaluate, Specify, and Deliver backported kernels for Lucid LTS.

Todo

kernel-maverick-pv-ops-ec2-kernel (0/0/3)

The current EC2 kernel is based on the very large Xen patchset. A pv-ops based kernel would need a much smaller set of patches which could be maintained as a kernel flavor instead of the topic branch used for the current EC2 kernel.

Todo

kernel-maverick-tracing-support (0/1/6)

New kernel tracing functionality will enable more efficient debugging of kernel issues. Analysis tools are provided to examine the data more rapidly and accurately. Scripts are provided so an end user can easily run them and upload results to a launchpad bug.

Todo

kernel-maverick-ubuntu-delta-review (0/0/1)

Review of the current Ubuntu Kernel delta. This session will look at the current delta comprised of both patches to the core and the ubuntu specific drivers. The aim is to record what we are carrying, review the reasons for that component(s) to be carried, and recommend replacements, updates, cleanups, upstreaming etc of those components.

Todo

kernel-maverick-union-mounts (1/0/3)

Union mounts have seen progress since last time they were evaluated as a replacement for aufs. Determine whether union mount are now a viable alternative for Maveric and if the work required to maintain them will be less than aufs.

Todo

kernel-maverick-upstart (0/0/4)

How do Upstart and planned changes affect Kernel?

Todo

kernel-maverick-version (1/0/2)

Discussions on the likely mainline kernel version for Maverick.

Todo

security-m-apparmor-profile-packaging (0/0/1)

For maintainers, AppArmor profiles are packaged either in the application that the profile applies to (eg, mysql or firefox) or in the apparmor-profiles package for profiles that are not officially supported yet (eg, they are in development). This presents maintenance difficulties and a barrier for people to include these profiles in their packages. This should be made easier.

Todo

security-m-kernel-hardening (0/0/2)

Review additional kernel hardening features.
