dtrace discuss - Mar 2007 - instrument sfmmu_kdtlb_miss:entry??

Hi,

    is there a way to instrument entry of assembler function 
"sfmmu_kdtlb_miss" to use Dtrace infrastructure??

i know there is no "supported/standar" one since it does not appear as
a
fbt available probe. It has no "save" instruction and that seems to be
one of the reasons.
I''m talking about test system so maybe we can hack it with mdb??

TIA,
Gonzalo.

DTrace cannot instrument code that is executed at TL>0.   This applies
to sfmmu_kdtlb_miss is it is in the DTLB_MISS trap path and therefore
executed at TL>0.
