Line 107: | Line 131: |
Key design points for this objective: * No plymouth at all. * No usplash for a default boot. * usplash will be started for fsck, and for entering a passphrase for encrypted root partitions. * X will be started as early as possible in the boot process and just display a bg image with a throbber. Once enough of the system is up, gdm starts and replaces the throbber. |

{{{ - don't move drivers into initramfs, Scott says that the boot will be fast enough to justify having a black screen until the driver gets loaded by udev |

- select X.org server version for Karmic: * upstream release dates cannot be predicted (plan: http://lists.x.org/archives/xorg-devel/2009-April/000774.html) * current Karmic plan: 1.7 this would bring libxi 2.0, inputproto 2.0, evdev 2.3(ish) - intel driver version: * 2.7.1 in karmic, planned to upload 2.7.99 next week * 2.9 will disable non-KMS support * beyond 2.9, no big changes planned * current Karmic target: 2.8, with possibility of 2.9 |
<ghexsel> - According to Phoronix (http://www.phoronix.com/scan.php?page=news_item&px=NzI4OQ). the schedule slipped. Will it still make the cut? <bryce> - presumably yes; if not we'll ship whatever -rc version is available at the time, and backport fixes as appropriate. |

In an ideal world the user might not even notice the lockup) - Tagging intel and ATI bugs in LP: both with chipset and symptom tags There is a wiki page with all the tags listed. - We need a platform for testing (defined set of functionality that we want working on a defined set of cards). We can use this to measure the quality of the release. The list of certified hardware for example. Apple has limited/bounded set of hardware and MS has the Windows logo program. - Is there a way to get a list of the most common hardware out there? }}} |

Summary
This specification provides a roadmap of X.org changes for Karmic, as well as a compatibility requirements listing of versions of dependencies we will want our video drivers to support.

KMS / Flicker-Free Boot Kernel mode-setting (KMS) is a major target objective for this release. We may be updating to newer versions of mesa if needed for KMS support. We anticipate that not all drivers will support KMS, so the kernel will be determining whether to use KMS or not on a per-driver basis, and if KMS is not in use, will boot similar to how it's been done up to now. 2. Fast Boot / Fast Resume Improving boot and suspend/resume speed is another major goal for Karmic. Our objective is to boot fast enough that no splash screen is required. Therefore we will not be integrating plymouth into our boot process. Where boot speeds cannot be sufficiently reduced we will continue to use usplash. We anticipate KMS will help in achieving this objective, and are looking for additional ideas for improving X.org boot speed further. Key design points for this objective: * No plymouth at all. * No usplash for a default boot. * usplash will be started for fsck, and for entering a passphrase for encrypted root partitions. * X will be started as early as possible in the boot process and just display a bg image with a throbber. Once enough of the system is up, gdm starts and replaces the throbber. 3. Virtual Terminals In Karmic, VT1 will be used for X, VT2 as a console login, and VT3 for kernel log messages.

Design / Rationale
-intel version 2.9 may be available in time for Karmic. There are no major features planned for that release; mostly it will be removing non-KMS code (not something we care about). However it may contain some worthwhile bug fixes, so may be worth consideration if it is released with sufficient time for integration; we'll plan on 2.8 for now and see how things go.
Implementation Tasks
- (DONE) Write roadmap
- (DONE) Send roadmap to video driver partners, Mobile team, and any other X.org requirements consumers
- (DONE) Pull intel-gpu-tools into Karmic/Universe
(DONE) Update directions at https://launchpad.net/~ubuntu-x-swat/+archive/x-freeze-test (Probably move into wiki)
- (DONE) Follow up with jbarnes regarding automatic GPU lockup resetting / apport triggering
- (DONE) Ogasawara says she can obtain a listing indicating the most common video hardware; this needs following up on
- (DONE) Provide jbarnes with a listing of the hardware Canonical certifies against
