Richard, Zephaniah, Chris Blizzard,
Ted, Marcello, Chris Ball
Leave battery in unit. Don't remove/insert battery A/C adapter plugged.
Has experimental firmware that goes from power-on to running inside Linux
in 2 seconds. Requires ditching VSA (use hacked pci config library
in kernel so drivers don't change) and changes to NAND FLASH layout
to avoid whole-NAND scan (Mitch has hack that uses fake bad blocks
to contain boot wad, but it might be better to use FLASH partitioning
Still some questions about what is going on with new touchpad.
Suspicion is software.
Several wireless fixes - hang during scan, association issues.
Build 194 has them, seems to work.
Updating from Insyde:
We still have some Insyde board in Cambridge, they need to updated.
Productive trip, useful discussions.
Ted: Ethernet is working, Mitch doesn't need a sample of the device.
Victor: Will send mail about quantities for B2.
When will quantities of CaFe chips be available? We don't know.
Testing and screening them may be the gating item for B2.
Blizzard: disposition of B2 units to developers and countries.
Still up in the air. Jim: Are we going to ECO B1? Jim, Lindsay,
Chris, Walter need to discuss next week. No other units have
failed despite extensive testing. One change is to replace a
tantalum capacitor with a different one.
AI: Andres - check with Dave Woodhouse about flash layer and partitioning.
Chris Ball - performance work. Tinderbox will record time stuff and cjb
is establishing a baseline so that when new Cairo and Gecko bits hit, we
will know what the effect is.
Chris Blizzard - stability csar. Working with redhat on build tracking
stuff, probably adding personnel.
BIOS. Many small FW fixes to support various random USB keys,
fw updater, and fw+nand.
Jordan: DCON and X hacks, RandR code. It is rotating, faster, using
Putting code in git, needs help shaking it out. How will we communicate
board type to user space?
Topic for next week: Device tree.
New kernel features in 2.6.19: should we move up? Andres thinks that we
should move to 2.6.19. We will target 188.8.131.52 for B2 - do one update
vs Linus before B2.
MarkF says (on IRC): Dec 29 for ASICs, board 1st week in January. Alps
item for B2 build.
