Notes from this meeting:
OLPC Software Call 08/01/2006
FBDev Driver Working
- added command line option to set resolution
- andrew morton pulled in patch from jordan's tree
- item: make sure it gets pulled into Linus' tree
EXA Driver
- hole using linuxbios
- need to test it!
- can run on linuxbios or the insyde bios
- requires changes to the config files? - in the wiki
- documented on the Hardware_Drivers page
OLPC Image Build page
- it's done, needs to be linked from other pages
LinuxBIOS issues - kexec of fedora kernels?
- ron swears that we don't need a mem= line?
- problems go away if you just use the mem= line
- need a tarball for the main kernel and the linuxbios kernel
- same kernel source in the rom as in the main image
- bliz believes that linuxbios and main kernel image need to be the same
- different goals
- jordan is going to mail ivan about getting tarballs in an
"official" place
Audio Driver
- alsa ctl for sensor selection has been added to the main tree and
pushed upstream
- jg doesn't know if it's made it into a linus tree or not
- jg will mail jaya and see if it's in a linus tree or not
- if not, we can pull alsa into the olpc-2.6 git tree
Display
- working version now
- working to improve the display now (could be twice as bright, mlj
is driving)
- haven't found out if they have hooked it up and tried the swizzling
CAFE
- we have a hardware spec for this now
- 136 pages now
- mark is doing a review, marvell will probably have a cycle to
update docs and hardware
- discussion of distributions, kernel development and compilers
(rawhide uses gcc 4.1.x)
Library and App footprint looks like
- memory footprint
- on-disk footprint
- failure is running out of data pages to make the device useful
- some work at Nokia on OOM issues
- simply put: we don't know about Nokia
Tools
- Size footprint?
- tools already exist to check jffs2 file compression ratios
- bliz will post the url to the tool
- memphis? - SoC project to get good stats
- jg will talk to ivan about memphis
Power Management
- jg hopes mitch will own the issue
- systemtap is your friend
- video latency in the Geode at the hardware level?
- jordan will follow up - most info came from CRTs.
- AMD pain day is tomorrow
- mark still needs to know the exact video timings
- fb timings aren't enough? don't know what it is exactly.
- correlation between dot clock and data available? jg doesn't
know. ask david woodhouse?
- found a diagram in the data sheet, don't know if it was enough
- jg will follow up
