There was a reason it was not announced, it has a number of issues but was for core developers to verify the current state of F17 and fix a number of issues before a widely announced release later in the week.

11.3.1 development build 30 for XO-1.75
This build brings in OFW improvements, audio fixes, s/r hang fixes, powerd, keybdshim and touchpad fixes. Updatable via olpc-update -- try the cmdline below. Notes: - Record Activity will sometimes hang - #11657 - The getty on the serial port is _disabled_ by default now (that's the workaround). It gets enabled when you hold the check game key during boot (for verbose boot).

One nice thing about os30 is that the combined kernel and olpc-powerd fixes and tunings mean you can actually use aggressive suspend resume in the sun to amazing power-saving results.

Short paper on Nell (XO-3)
Chris Ball, Michael Stone, and I submitted a short paper about Nell's design for the 2012 Interaction Design and Children conference. It contains a much more coherent description of our ideas and goals than the random fragments at http://wiki.laptop.org/go/Nell. The paper is posted at http://cscott.net/Publications/OLPC/idc2012.pdf Comments and feedback welcome! Assuming the paper is accepted, we will still have to revise for publication, so also let us know if you found any of our arguments confusing, wrong, or simply disagree, so we can do a better job for the final paper. --scott -- ( http://cscott.net ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
[PATCH] olpc.fth - grow the root filesystem partition on boot
Grows the second partition so that it takes up all remaining space on the eMMC or microSD card. Fix for #11690. Part of #10040. Costs 120ms. (Use of a flag file costs 130ms). Does not proceed if extra partitions are found. --- Note: applies to XO-1.5, XO-1.75, and XO-3. Note: resize2fs must be run by the operating system for the space to be available to the user. olpc/olpc.fth | 43 +++ 1 files changed, 43 insertions(+), 0 deletions(-) diff --git a/olpc/olpc.fth b/olpc/olpc.fth index 368e3c5..cd3b723 100644 --- a/olpc/olpc.fth +++ b/olpc/olpc.fth @@ -72,6 +72,48 @@ false value enable-serial ; [then] +warning @ warning off +0 value mbr-ih +warning ! + +: get-size ( -- size ) size mbr-ih $call-method d# 512 um/mod swap drop ; + +h# 1be. 2value pt \ device byte offset to start of partition table +h# 10 value /pe\ size of a partition entry +/pe buffer: pe \ partition entry buffer + +: pe-seek ( d.pos -- ) seek mbr-ih $call-method drop ; +: pe-read ( d.pos -- ) pe-seek pe /pe read mbr-ih $call-method drop ; +: pe-write ( d.pos -- ) pe-seek pe /pe write mbr-ih $call-method drop ; + +: pe-start@ ( pe -- start ) pe h# 08 + le-l@ ; +: pe-length@ ( pe -- length ) pe h# 0c + le-l@ ; +: pe-length!
