Is there any way to access the full 64-bit "long long" return value
from the return probe of the fbt provider, when running on the 32-bit
Solaris x86 kernel?
E.g. how do I get access at the full 64-bit hrtime_t result
from the kernel's gethrtime() function?
# isainfo -kv
32-bit i386 kernel modules
# dtrace -n 'fbt::gethrtime:return { printf("%llx", args[1]); }'
... prints lots of 32-bit values; the high order 32-bits from hrtime_t are lost
...
And it seems that a similar problem exists for 64-bit arguments
and the entry probe; but in this case I can work around the problem
by assembling the full 64-bit argument from two raw argN argN+1
values:
This works:
# dtrace -n 'fbt::new_cpu_mstate:entry { printf("%llx", (arg2 << 32) | arg1); }'
But this doesn't:
# dtrace -n 'fbt::new_cpu_mstate:entry { printf("%llx", args[1]); }'
