few new things I see on linux-omap kernel community

After a long while of staying off linux-omap, been watching it rather closely recently.. here are some interesting stuff I saw this month:
  • Power Management: Operating points and general PM strategy for handling for various silicons here
  • Silicon Feature support for OMAP3 here
  • New silicon support: OMAP35xx and 36xx support being introduced.
  • Discussion on memory and cache issue here
  • ETM, ETM support here
  • few new PMIC - 6030 and 5031
  • hints of wl1251 support getting upstream
  • IO_ADDRESS is dead use io_remap like the rest of the world
  • spring cleaning of omap850/730 series
and of course a bunch of stuff I have missed posting here such as move to 2.6.32-rc4 by Tony and Kevin, both pushing out patches to mainline etc.....

some interesting posts

High time I "ported" my posts from facebook back here it goes
Some really bad code stories:

  • shared by rob clark - how bad can some code go??

  • Aint this cool:

Techno Curios:
  • Tired of fullspeed, highspeed, lowspeed?? how about superspeed?? tired of acronymns already??

  • Search for my cheap oscilloscope goes on:

Hacks 'nd bytes:
  • PS3 back with Hulu..

timing diagrams


This is kinda a cool app that runs on ubuntu to draw timing diagrams as follows:
Example(from the drawtime website):
CS1 = 1, OE = 1, ADDR = X, DATA = Z.

CS1 = 0, OE = 0, ADDR = "".
OE -tOE> DATA = "";
CS1 -tCS1> DATA;

OE = 1, CS1 = 1, ADDR = X.
CS1 -tH> DATA = Z;

and you can now generate all those cool waveforms without having to worry about did you get the lines right etc..

more such cool stuff here
