[http://lists.laptop.org/pipermail/devel/2009-February/023079.html 9.1.0 was cancelled]. However, many of the planned features found their way into newer OLPC OS [[releases]].
= Overview =
This release is the first major new feature release after 8.2. Its is the first of two major feature releases we want to deliver in 2009. The target date for this release is March 15, 2009 (Note: date and feature set not final and subject to change).


{{Deprecated}}
This release must run on C1, C2, C3 and the new C4 motherboards. (check exact list and add URL)
{{RightTOC}}


This page defined the requirements, schedule and overall planning for a release 9.1.0.
= Technical Strategy =
This section outlines the main areas of technology that we will focus on improving. All of the specific features should address one of these primary concerns. The choice of these comes from listening to users and deployment leads and hearing what their concerns.


[[Feature requests]] tracked features, requirements, and requests, and plans by customer;
The first two strategic priorities are focused on making the XO work the way users expect it to and helping get the XO deployed more quickly in more countries. The third is also an area where we have unmet expectations. However, there have been many different understandings of what collaboration means. This release should clarify a few specific examples of collaboration and ensure that those are supported and reliable. We have a window of opportunity to build something completely new and original in this space. If we come up with a new work flow here, it must be reliable and usable within the constraints of the existing technology.
[[Feature roadmap]] tracked all software features by technical strategy.

== Greater Reliability and Performance ==
# No loss of data. Fewer crashes and fewer open bugs than 8.2 and previous releases. See also: http://wiki.laptop.org/go/User:Gregorio/8.2.0_release_criteria
# Works the way the manual says it works
# Better performance includes faster GUI interactions. Includes launching activities, switching from one activity to another, using the journal and using the frame. GUI, activities, back ups.


= Overview =
== Easier to Deploy and Maintain ==
This release is the first major new feature release after [[8.2.0]] Its is the first of two major feature releases we want to deliver in 2009. The target date for this release is March 7, 2009 (Note: date and feature set not final and subject to change).
Quick, clean way to upgrade XOs in the field. Covers several cases including
# Installing images in the warehouse
# Upgrade in the schools
# Updating activities
# Activation and Leases


This release must run on all existing XO hardware.
Each should be optimized for case where XS is available, Internet only available and no Internet (AKA USB). Must make it easier to load new image, latest translations, activities and content bundles.


= Technical strategy =
== Collaboration ==
This section outlines the main areas of technology that we will focus on improving. All of the specific features should address one of these primary concerns. The choice of these comes from listening to users and deployment leads and hearing what their concerns are.
# More fully defined activity sharing paradigms, especially with write.
# At least one data collection and analysis application supported with an architecture defined for others to follow.
# Easier file sharing between XOs and easier to generate and upload user generated content to the internet.
# Greater scale for number of XOs that can collaborate.
# Segregate users so that all the available channels and spectrum are used.


The strategic priorities are to make the XO work the way users expect and help get the XO deployed more quickly in more countries.

The following are critical must-deliver features for this release. The categories are listed in priority order. <br>


'''See all top priority features with details on one page [[Feature_roadmap/Page_of_all_features_that_target_9.1.0|here]]'''
From Emiliano and Erik in e-mail:<br>
Allow Uruguay to sign their own builds so that they can take an image from us, add their customizations then sign it and deploy on the XOs with the existing OLPC provided upgrade tools (e.g. olpc-update and USB keys). <br>


Feature categorized in to the four main areas are list below: <br>
An efficient system upgrade method (ideally this preserves user ata, ideally it can be done in schools with minimal manual effort). <br>


1 - Rebasing on F10 and allowing "regular" Fedora window managers and applications to run. <br>

From Wad trip on April 2008 in priority order: <br>
# '''Speeding up the user interface'''
# '''Power management of the laptop to extend the life of a single battery charge.'''
# '''Improvements to the group model''' (specifically, they are looking at support of multiple groups, possibly defined and shared between users --- e.g. the teacher makes a group that is "first grade", so it is easy to invite only the first graders to join an activity.
# '''Easy backup of the laptops'''


''' Please help add all potential activities to this table. Add as much info as you have and leave the rest blank.'''
From Kim Trip July 2008, not in priority order: <br>
'''Activation lease security feature''' <br>
Requirement - if the laptop is stolen, and doesn't contact its local school server within some period time (activation lease time); then it will tell the user that it will not activate on next boot and provide date and time. When it gets in the vicinity of the school server again, it will be
re-activated automatically.


=== Nominations ===
Requirement - it is not possible to set the date on the laptop to keep it within the lease period or to force it to outside the lease management. This might mean you cannot change the date or there is no root access, or it might mean an alternate time source is used.
''(sign your nominations with <tt><nowiki>--&nbsp;~~~~</nowiki></tt>)''
* I nominate [[Develop]]. Version and test case upcoming. [[User:Homunq|Homunq]] 15:04, 10 December 2008 (UTC)


* I nominate [[StarChart]] (http://www.wa1gsf.net/downloads/XO/StarChart-5.xo) version 5 maintained by [[User:davewa|David Wallace]], licensed under GPLv2+. Note that Version 6 is in development and will have 2 more features and should be i18n-ed. Release of v.6 was planned for 1/1/09 but is slipping (because I don't understand how to get the mouse click event). -- [[User:Davewa|Davewa]] 19:39, 10 December 2008 (UTC); edited Jan 6, 2009
'''School Server monitoring of XOs''' <br>
* I nominate SimCity http://wiki.laptop.org/go/Simcity and/or Micropolis, preferably Micropolis if we can get good response from a maintainer. [[User:Gregorio|Gregorio]] 15:21, 11 December 2008 (UTC)
I think there might be some work in the XO to make the information available; and a database and API spec from the school server. This is not as high priority for their deployment as the passive lease management, but I believe this feature will be important for any deployment. We should try to get feedback from other deployments as to the information we want to collect.


* I nominate [[Image_Viewer]] and [[Jukebox]]. [[User:Sayamindu|Sayamindu]] 20:30, 17 December 2008 (UTC)
Requirement: Provide XS database and an API so that countries can create reports and monitoring for various aspects of XOs:

''' Make it easier for Peru to add activities and content to a build''' <br>
This should allow them to add their own content and set of activities to a build after it is finalized and released by OLPC. The goal is for minimal or no OLPC involvement needed.


Possible QA milestones: <br>
'''Requirements for groups (in priority order for Peru)'''
- Start creating test cases for each feature. <br>
# Project Groups, which can be set up on the XO. These groups might stay together for days, weeks, or months - for example to discuss growing different vegetables or flowers. Generally smaller than a classroom. These groups can be created by students.
- Finish creating test cases. <br>
# Groups per classroom, to be set up on a School Server by someone with special access (needs a UI that can be use by a teacher with password, for instance). Use case is to be able to hand out books, vocabulary lists, etc. these would be best to do within a class.
- Execute all test cases once. <br>
# Groups at the grade level because each grade will have some common curriculum. This would be set up at the school server and require special access.

= Technical Possibilities =

There is more work readily at hand than we can do in time for this release. This section mentions areas to consider.

== Activity Related Work ==
Requests from Birmingham. <br>
New activities: <br>
Firefox, Flash, mplayer <br>
A spreadsheet (I'm going to use gnumeric until Socialcalc is ready for production) <br>
A more full featured pdf reader (yes, I know there's the Read activity, but I'm planning on installing the full evince and making sure Firefox can open pdfs with it) <br>
A document editor the user can insert images into (the full Abiword would be great for this, but the current workaround [after editing a file] is to open write, then hit ctrl+n) <br>

General requests: <br>
Make it easy to sugarize third party applications.

Support Java in Browse. Needed to see Scratch web site <br>

A better color picker in Paint & Write. Current one is "It is made for professionals to get the HTML code of the color, but it also leads to error since people need to select the color in the circle and then in the triangle. It is giving bad time to people around here [Rwanda]". <br>
From Juliano in e-mail 9/1.

=== Most Commonly Used Activities ===

== Longer Battery Life ==
=== Requirement Definition ===
A list of UI actions which may affect power usage: [[Requirements#Power Management Requirements]]

Background on power draw including a break down watts used in different modes: http://wiki.laptop.org/go/XO_Power_Draw#The_Numbers

Our job is to increase battery life in as many modes as possible.

Suggestions from John/Gnu for increasing battery life follow.

Significant technical actions that could reduce the laptop's power draw:

* Allow users to disable the mesh: reduces power consumption of the WiFi chip, allows the WiFi chip to enter power-save mode, and most importantly, allows lid-closed suspend to totally power off the WiFi chip. #6955

* When the lid is closed, and the mesh is off (Wifi could be off or on), the laptop should totally power off the WiFi chip. This would lengthen the duration of lid-closed suspend (before totally draining the battery) from about 8 hours to several days. WiFi with an access point rather than mesh is now the default configuration in most schools, so this would have a dramatic impact on most deployments, particularly those with off-grid power. #7879

* Put the EC into deep sleep when in a lid-closed suspend. This will cut its power from about 60ma to about 20ma (check with rsmith), which would further increase the duration of a lid-closed suspend before the battery drains.

* Speed up Resume, which currently takes more than 1000 ms. A cheap shot at this is to unload the USB bus modules. The Extreme power management setting was supposed to do this ("USB-disabling") but it doesn't yet. This would make auto-suspends much less visible to the interactive performance of the laptop, probably cutting the resume time to 500ms, which would let us enable auto-suspend in more circumstances. Beyond this cheap hack, we should actually fix the USB drivers so that you CAN be using the USB -- the wifi/mesh in particular -- and still not hang for half a second uselessly on every resume.

* Fix serious bugs in resume and networking. These have so far prevented us from turning on autosuspend by default for three major releases (650, update.1, and 8.2.0), and in each release, we decide at the last minute that we can't fix these bugs because it's too late in the release cycle and we didn't fix them earlier. Multicast, ARP, mDNS, the Presence Service, and collaboration must all work in the presence of autosuspend. Much work has gone into fixing these, but neither the final nits, nor polish, nor system-level testing in a network testbed, has occurred.

* Reduce packet traffic during sharing -- particularly multicast traffic, which loads many machines (and wakes them up from autosuspend). This will require diagnosis and improvement of the presence and collaboration protocols. Some work was done on this, after the high packet traffic melted the WiFi bandwidth in early deployments (e.g. turn on 30 laptops in the mesh, none of them can usefully get anything done), but our main response was to tell later deployments "Don't use the mesh, use access points" -- a significant reversal that we should keep working to fix.

* Improve cpu idle detection. Currently we can't auto-suspend very often (only after >1 minute of no user interaction) because it's so heavy-handed. The cpuidle infrastructure in the kernel should be able to tell us when it's safe to suspend because no process wants access to the CPU for the next few seconds. Most of the pieces are there.

* Reduce useless polling by kernel, daemons, and activities. There's still a major Python bug that causes multi-threaded pyGTK2 programs to poll uselessly once a second (#4680, #4677). Much work was done to close it, but there is still a small sprint required to get it done. This not only reduces power use directly, but also allows the system to suspend because it doesn't appear that activities need to do some work soon.

=== [[9.1.0 Collaboration Requirements]] Phase 1 ===
Allow for intuitive mesh connection and activity-sharing. <br>
Must support first two use cases defined at: [[Use Cases#Collaboration Examples]]

[[Requirements#Mesh / Connectivity_Requirements]]

[[Requirements#AbiWord Sharing Requirements]]

http://lists.laptop.org/pipermail/sugar/2008-July/007407.html

May need to include that link in developer section below, tbd

=== [[Collaboration Requirement Phase 2]] ===
Interschool, other use cases.

=== Inter-school communication ===
What I see as most missing and most necessary is a safe space for collaboration between students at different schools, even in different
countries. <br>
http://lists.laptop.org/pipermail/localization/2008-July/001249.html

=== Groups ===
4043

== Performance and Reliability ==
Faster activity launching <br>
6472

- File/activity open

- File save

- Task switching

- Activity or main GUI responsivesness to cursor

- Hardware

- Prevent or warn when user starts opening too many activities. Reduce OOM problems and handle OOM better. Ensure that activities don't harm the system. Find and reduce memory leaks. Make the system more stable.

=== Suggestions from Marco ===
From: http://lists.laptop.org/pipermail/sugar/2008-July/007471.html

1 General UI sluggishness.

Without going too deep into the stack, I think there is a lot of space or improvement even in the python code. Michael mentioned icon cache
and mesh view layout, both areas of the code that didn't get any love for a while and where I'm convinced we can make big/quick progresses.
I'm planning to spend a lot of my time on this in the next release cycle.

2 Datastore performance.

I'd expect improving jffs2 performance would be a big win there. The UI can probably be smarter in the way it uses the datastore too Finally we
can try to improve at the datastore level, but there we clash with the rewrite plans. I think we should find an agreement on the datastore design and just try and get it done for 9.1.0, there are two many things blocking on it.

We need to allocate time and focus to do some good profiling and then attack the problems we find. That's why I'm advocating for the next
Sugar release cycle to be largely about perfomance improvements, bug fixes and code refactoring, with the possible exception of the datastore
rewrite.

== File Management ==
'''Candybag'''
Idea for a new activity: Candy Bag. You open a bag (i.e. you launch the
CandyBag activity), then you put journal entries in it, then sharing
this activity means that your friends can grab a candy in your bag. <br>

== Localization ==
Spell checking as part of l10n. (Sayamindu and Sur list)

Allow adding a language after the build is created and without OLPC intervention

Chinese support (Kim)

Better RTL support

SCIM (Sayamindu)

== Security Activation and Deployability ==
=== Faster Upgrade ===
Make it easier to upgrade many laptops in the field. Several cases: <br>

Updates:<br>
# XOs in warehouse need update before being shipped.
# XOs in school with no WAN
# XOs in school with thin WAN pipe (BW <= 1Mb/s)
# XOs in in school with good WAN (BW >= 1Mb/s)

Possibly sub-variants of in school case for Mesh, Wireless AP, XS.

Source: Bastien in Haiti and other XO deployments where it takes too long to re-image.

=== School server push of XO images ===
Requirement: The XO should be able to get the latest build from the school
server

* The administrator makes the desired build available in the designated directory. When ready, the administrator requests to 'push' the build to all laptops as they come on line. Both of these activities should be an easy-to-use UI at the school server.

* A test requirement is the ability to create a white list of serial numbers that should be upgraded with the push.

=== Activation lease security feature ===
Requirement - if the laptop is stolen, and doesn't contact its local school
server within some period time (activation lease time); then it will tell
the user that it will not activate on next boot and provide date and time.

Requirement - it is not possible to set the date on the laptop to keep it
within the lease period or to force it to outside the lease management. This
might mean you cannot change the date or there is no root access, or it
might mean an alternate time source is used... (not trying to solve the
problem, just want to note this requirement).

Requirement: Provide XS database and an API so that countries can create reports and monitoring for various aspects of XOs:

* Version of code
* Which laptops are being seen each day
* Total number of laptops being seen per day
* Number of laptops accessing the internet
* List of URLs being accessed
* List of URLs per laptop
* Which activities are being used per laptop
* Number of minutes in each activity per laptop; can we determine (and subtract) idle time?
* Number of minutes in each activity within and outside of school hours (perhaps this means we capture the 'start' time of each activity and allow the reporting to decide if this is during or outside of school hours).

Background and implementation ideas: <br>
I think there might be some work in the XO to make the information available; and a database and API spec from the school server. This is not as high priority for their deployment as the passive lease management, but I believe this feature will be important for any deployment. We should try to get feedback from other deployments as to the information we want to collect.

=== Customized Startup Images ===
Must allow changing startup picture by copying an image to the XO. This should not require any OLPC developer intervention and should not need a new or special build.

Already present in 8.1.0. See: http://wiki.laptop.org/go/Tweaking_the_boot_animation

Should allow setting the language at the factory or when upgrading/re-imaging. The idea is to not require the kids to click the control panel to get to their language. One idea is to include it in the choice you make on first boot (e.g. name and color) better would be to set the language at install. <br>

More prominent help information - Brianne, G1G1 <br>
One idea from Eben. From: http://lists.laptop.org/pipermail/sugar/2008-August/007547.html <br>
All of our initial discussions on help focused around a contextual help system, and I still hope that this is where we'll be taking this in the future. By embedding (?) icons within the secondary palette menus for various devices, objects, activities, and even individual buttons and controls, we can provide a way to launch into the help activity and dive directly to the relevant info for the activity, control, etc. selected. In addition, I'd like to support a community driven help system by which, in addition to the activity/olpc provided help, it's possible for kids to add tips, tricks, images, tutorials, and other info to these sections for later consumption by peers.

This is a noble, but ambitious goal, which is why a simple and static help activity is the present solution, and why it's only integrated into the system at a single point - the activity itself.

http://lists.laptop.org/pipermail/sugar/2008-July/007390.html

1. The datastore <br>
Sugar's design calls for a centralized rich data storage system, the
datastore. The datastore provides secure, limited file access to
Activities, manages file metadata, maintains a differentially compressed
history of all work, ensures reliable backups to a trusted server, and
mediates the connection to removable media. Every one of these features
is crucial to Sugar's functioning, and almost none are really working at
this time. We cannot afford another release based on the present
datastore, as it fails to implement the features we require, and is
unreliable even in the features it supposedly implements.

Solution: <br>
There have, at this point, been at least five distinct proposals for a
next-generation datastore design, all differing in underlying
implementation and user-facing functionality. We need to have a Once And
For All datastore summit, draw up a compromise datastore design, and
implement it. We can do this by 9.1.0, if we are willing to make it a
priority.

2. OS Updates <br>
We now have hundreds of thousands of laptops deployed in the field,
running a variety of OS versions. OLPC cannot afford to support a
multitude of decrepit versions, and children cannot afford to suffer
defects that have long since been fixed. We need a reliable, fast,
update system that does not rely on the network, so that children
everywhere can move to the
latest version of Sugar without losing their data. The update system must
support tremendously invasive upgrades, like repartitioning the NAND and
replacing JFFS2, because we expect to do this in short order.

Solution: <br>
A secure usb autoreinstallation stick is required. It is not technically
challenging to implement, but it must be made a priority, and then be made
widely available and idiot-proof.

3. File Sharing <br>
Students and teachers have no good way to distribute files directly from
one person's Journal to another. If all Activities that open a file do
not implement Collaboration, then there is simply no way to transfer that
file over the network. This is the most basic possible network
functionality --- FTP was standardized in 1971 --- but it is completely
missing from our system.

Solution: <br>
A number of technical proof-of-concept programs have been written for
distributing files, using methods like HTTP over stream tubes and
Cerebro's Teleport. There is an excellent set of [[Specifications/Object_Transfers|UI mockups for this]
functionality. All that is left is to Get It Done.

* [[Summer_of_Code/Ideas#Publication_and_Journal_sharing|A Summer of Code application]]

4. Activity Modification <br>
A keystone of the Sugar design has always been the user's ability to edit
any Activity, and to cement this a "View Source" key was designed right
into the hardware. This functionality is simply missing, and that
prevents us from making our principal claim regarding an emphasis on user
modification.

Solution: <br>
"Develop" must be polished, finished, and included by default. This will
require modifications to the core system, in order to support an endless
variety of slightly modified Activities. It will also require work on the
Develop program itself. If volunteer efforts are not moving fast enough, OLPC
must ensure that someone is working on the problem as a professional.

* [[View_Source|Current status of "view source"]]
* [[OLPC_Human_Interface_Guidelines/The_Laptop_Experience/View_Source]]
* [[EAG_The_Laptop_Experience:_View_Source]]

5. Bitfrost <br>
Sugar, as it currently stands, is among the least secure operating systems
ever, far less secure than any modern Linux or Windows OS. I can easily
write an Activity that, when run by the user, escalates to root privileges
and does anything I like with the system. Given Sugar's competitive
status against Windows XO, this failing threatens the very existence of
the project. The Sugar designs have long stated that safely running
untrusted code from a classmate is a key goal for learning, but the
current software accomplishes precisely the opposite.

Solution:<br>
NO ONE IS WORKING ON BITFROST. That's right. Everyone who was working on
Sugar security (after activation) has either left OLPC or moved into
another role. Someone must be assigned to continue the security work, or
it will certainly never make progress. Anyone who _does_ take on this
challenge will start from a much better position than previously,
because many of the Vserver features have moved into the mainline kernel
over the last few versions. The kernel now contains a number of new,
powerful isolation and control primitives.

6. Power management <br>
Power management is the raison d'etre of the XO hardware. It is the
reason that the hardware took four times as long to develop as a standard
laptop, the reason that we suffer from the closed Marvell operating
system, the reason that OLPC's best engineers flew around the globe
fighting with details of voltage and capacitance. In an increasingly
crowded low cost laptop market, it is one of OLPC's few remaining
distinctions. As of 8.2.0, aggressive suspend is available, but its
functionality is still far from the target.

Solution: <br>
Enabling aggressive power management is a major challenge, perhaps more
difficult than anything else on this list. We know what is required for a
first step: ensure that we can reliably wake up from a hardware timer.

This single feature would be enough to enable a basic sleepy approach
that is truly transparent to software. Other work includes removing USB
from the critical path on resume. Aggressive suspend may not be ready for
9.1.0, but if no one is working on it it will never be ready.

== Easy Update for G1G1 ==
I think this is the biggest missing feature for G1G1 users, honestly. The software update control panel for activities is a great step in the right direction, but to really get people into Sugar moving forward, we have to make one-click updates a reality. They have no school server or other centralized source doing it for them, and we can't expect many to go through the manual update process. Once we have a super-simple control-panel-integrated dev key request process, we should also adjust the update UI to offer cutting-edge updates to those with keys.

From Eben and Joe

== Suggestions from [[User:CScott]] ==
* Better "legacy app" compatibility; this should allow us to run existing apps like firefox, pidgin, and gimp in a reasonable manner:
** Replace matchbox window manager with [[XMonad]], [http://en.wikipedia.org/wiki/Metacity Metacity], [http://awesome.naquadah.org/ awesome], etc. Should provide both 'full screen' mode and traditional 'tiled' mode.
** Switch to standard freedesktop.org [http://www.freedesktop.org/wiki/Specifications/startup-notification-spec startup notification] mechanism: <trac>5271</trac>
** Implement freedesktop.org [http://www.galago-project.org/specs/notification/index.php notifications mechanism] for alerts (low battery, low disk space, available software update)
** Refactor home/friends/mesh view as operations on root window, so they make sense in a multiwindow setup. (It's been suggested that looking at the xpenguins code is instructive for understanding how nautilus,etc arrange their root window.)
* Improved antitheft mechanisms:
** ECO fix and EC improvements
** Security control panel, with "am I stolen" and lease renewal buttons: <trac>1502</trac>, <trac>6428</trac>
** olpcrd work: <trac>7397</trac>
** Revoke root capabilities when booted with security enabled: <trac>7562</trac>
* Improved update mechanisms
** Real COW for pristine versions, allowing... <trac>3581</trac>
** ...binary-diff updates over http (avoiding rsync in many cases) <trac>4259</trac>, etc
** Integration of core OS updates with software update control panel: <trac>7618</trac>
** Integration of software updates with notification system
** Incremental updates of activity bundles (only changed files)
** Send back statistical data when checking for updates (batmon, etc) <trac>4594</trac>, <trac>6447</trac>
* Security/isolation work
** Implementation of P_SF_CORE, P_SF_RUN
** Mechanism to validate updates to loopholed activities & allow user to manage exceptions
** Persistent activity storage
** NSS modules for rainbow users and for olpc/root users
** Rainbow
* Journal improvements
** Proper display of 'new versions' of activities
** Tagging system to allow folder-like management for advanced users
** Datastore rework
** Direct execution of activities from datastore (avoid installation step) <trac>7713</trac>
** Ability to have multiple versions of an activity installed concurrently. (API work necessary: <trac>7713</trac>)
* Translation improvements
** translation system should look in local, then activity, then system translation tables, then repeat for each in a set of fallback languages (eg, quechua, spanish, english)
** separable translation packs
** wiki-like editing of translatable labels in the UI
* "Asynchronous internet"
** Integration of wwwoffle with small local cache
** Content bundles to seed that cache
** Mechanism to request downloads later
* Library improvements
** Better indexing system, integration w/ asynchronous internet
* Fedora integration
** tools to manage forked packages better. To start with: a notification tool to let us know if a new upstream release has occurred for a package we have forked.

== Replacement File System ==

The current file system used on the XO ([[http://en.wikipedia.org/wiki/JFFS2 JFFS2]]) was developed in the days of 32/64MiB NOR flash devices and does not scale well to the 1GiB NAND devices we are using today and certainly will not deal well with larger devices in gen 1.5 and gen 2 systems. The main issues are that JFFS2 needs to scan all blocks at mount time and that the garbage collection algorithm increasingly consumes CPU cycles as the system fills up. The first issue manifests itself as large delays at boot up to mount the file system as it is full (need to quantify this), and the second issue simply means less CPU cycles can be dedicated to user task processing. In the last few years, there has been much activity in the embedded Linux world on alternatives to JFFS2 and we need to investigate these to determine which one best fits our needs:

* [http://www.yaffs.net/ YAFFS2] : Has been around for several years and in active use in the embedded space. It does not provide compression out of the box as the devices that use it often carry already compressed data such as MP3 and MPG files.

* [http://www.linux-mtd.infradead.org/doc/ubifs.html UBIFS]: A new file system recently merged into the kernel designed for use on large flash devices. Supports compression out of the box and supports disabling compression on a per-inode basis, which is something we desire.

* [http://logfs.org/logfs/ LogFS] : Another JFFS2 replacement designed for fast operation and scalability. Still fairly new and not in very active use AFAIK.

* [http://btrfs.wiki.kernel.org/index.php/Main_Page Btrfs] : A very new file system that is primarily targeted for large storage systems with features such as snapshotting, RAID support, and online fsck. David Woodhouse has expressed that he will look into getting this to work on NAND, but it is too new of a code base to consider for 9.1

* Managed NAND : (Not an option for existing XO machines, but might be a direction for future hardware) The industry seems to be moving away from raw NAND in favor of a NAND-chip plus microcontroller solution. The microcontroller implements a Flash Translation Layer that hides the low level NAND details, presenting a higher level interface that looks like an ordinary hard disk, so an ordinary filesystem layout like ext3 could be used. The driving force behind managed NAND is rapid hardware evolution toward multi-level-cell NAND chips and smaller process geometries, which change important NAND parameters like page sizes and ECC. The situation is similar to what happened with hard disks in the 80's, where raw-disk interfaces gave way to SCSI and IDE, which hide the ugly low-level details that changed every technology generation. Managed NAND options include LBA-NAND from Toshiba (pin-compatible with NAND chips), eMMC from multiple vendors (with an SD/MMC-compatible hardware interface), and various "disk on chip" products (IDE-compatible interface).

=== Development Process ===

* Analyze and quantify the use patterns that trigger issues with JFFS2.
* Gather requirements for a new file system that go beyond solving above issues.
* Develop/integrate a set of tests for FS performance and reliability that take into account our use patterns, the above issues, and any other features we wish to validate.
* Study the three main alternatives (YAFFS, UbiFS, LogFS) to determine what requirements they meet
* Run our FS test suite on above alternatives
* Analyze test results and requirements study and make a decision on which alternative to use.

=== Deployment Process ===

Once a file system is chosen from the above process, we will have to:

* Integrate the file system into our kernel if it is not upstream (YAFFS2 or Logfs)
* Integrate the file system support packages into our build system and file system images
* Update our build scripts to generate the proper image type for

=== Activity Impact ===

This change should not have any impact on activity developers as it is at a very low level of the stack.

=== End User Impact ===

End users will see faster boot up time and will not see (as much) performance degradation as the file system fills up.

This page defined the requirements, schedule and overall planning for a release 9.1.0.

Feature requests tracked features, requirements, and requests, and plans by customer; Feature roadmap tracked all software features by technical strategy.

See also notes from XOcamp 2 technical conference.

Overview

This release is the first major new feature release after 8.2.0 Its is the first of two major feature releases we want to deliver in 2009. The target date for this release is March 7, 2009 (Note: date and feature set not final and subject to change).

This release must run on all existing XO hardware.

Technical strategy

This section outlines the main areas of technology that we will focus on improving. All of the specific features should address one of these primary concerns. The choice of these comes from listening to users and deployment leads and hearing what their concerns are.

The strategic priorities are to make the XO work the way users expect and help get the XO deployed more quickly in more countries.

Easier to deploy and maintain

Easier to deploy focuses on facilitating the imaging of XOs, their activation, the installation and extension of custom leases and anything else needed to get the XOs from the factory in to the schools. Some examples include:

  1. Creating customization images (to include language packs and rpms)
  2. Installing images in the warehouse
  3. Activation and Leases

Easier to maintain focuses on upgrading, keeping the XOs working, monitoring them and allowing recovery of data from errors. Some examples include:

  1. Upgrade in the schools
  2. Updating activities
  3. Reducing power consumption

Greater reliability and performance

  • No loss of data. Fewer crashes and fewer open bugs than 8.2 and previous releases. See also: http://wiki.laptop.org/go/User:Gregorio/8.2.0_release_criteria
  • At the time of the release, works the way the manual says it works. That is, all of the things explained and listed in these manuals must work as described.

http://www.laptop.org/manual/

  • Better performance includes faster GUI interactions. Includes launching activities, switching from one activity to another, using the journal and using the frame. GUI, activities, back ups.

Primary release drivers

Date: March 7, 009

Customers: Rwanda, Peru, Ethiopia, Uruguay, Haiti, OLPC Birmingham, Mongolia, Ghana, Dubai, Lebanon
