Don't know if this is the reason of our problems but I think there is
something to investigate around timer interrupts:
/ # cat /proc/interrupts
CPU0
16: 68 UIC 1 Level serial
LOC: 0 Local timer interrupts for timer event device
LOC: 0 Local timer interrupts for others
SPU: 0 Spurious interrupts
PMI: 0 Performance monitoring interrupts
MCE: 0 Machine check exceptions
Any idea what the problem can be ? How does QEMU generates timer
interrupts ?
The ppc405 timers were trashed by ddd1055b07fd ("PPC: booke timers").
I guess at the time, in 2011, there were no possible ways to test
regressions :/
This is addictive. I will look into it, I hope it's only a question
of adding back the TSR and TCR store helpers.
Thanks,
C.
