Hello,
There is a bug item on the bug tracking system to which I promised to provide more information. However, I couldn't do it this week, and I'm going to be away from the test board next week.
http://dev.laptop.org/ticket/68
Can somebody with a board try the code Marcelo wrote on the page with and without a USB network adaptor? Or, even better, can somebody do following (or something like that) in Squeak, err, in the OLPC eToys environment with and without network?
before := (FileStream readOnlyFileNamed: '/proc/interrupts') next: 10000. time := 200 timesRepeat: [Display forceToScreen: (0@0 corner: 400@400)]. after := (FileStream readOnlyFileNamed: '/proc/interrupts') next: 10000.
The above code basically reads /proc/interrupts twice, before and after big memcpy like operations.
Thank you so much!
