I was surprised to find myself at the decrement interrupt when running my new stuff. That is against ePAPR, right? Does u-boot at least make sure that the DEC is set to some large value before it leaps at me? I don't mind forcing EE=0 but I'd like to make sure I make it that far into the code :) -JX
Jimi,
Not sure how or why you are seeing this, but u-boot should disable interrupts in common/cmd_bootm.c
Look for disable_interrupts() -> this should set MSR[EE] = 0.
What about the rest of MSR -- ME/CE/DE?
I dont think we ever turn on CE in u-boot, DE would only get set in some weird external debugger build.
