Hi Kyle,
Yes, bge_nic_put32()/bge_reg_get32()/bge_reg_put32() are all defined as
inline functions. This is why you can't set breakpoint against them.
Carson is investigating this issue on a IBM BladeCenter inside SUN.
Regards,
Kerry

Hi Kerry,
I looked up the bug you filed, hoping to add this to it myself, but I
didn't see anyway for me to do that (is bugs.opensolaris.org read-only?)
Anyway, over the weekend I poked this a little more, and I'll admit it's
got me stumped.
The disconnect definitely occurs at:
bge_asf_pre_reset_operations()
But looking at the code, I can't tell where. There are calls to 3
functions in that one, but setting break points on those didn't add any
info - it appears they were never called? - Or could the calls have been
inlined or optimized out by the compiler?
I'm going to have to go read up on how to use kdb, so I can examine the
arguments passed to the function, etc.
Thanks for all your help!

Hi Kerry,
Maybe this will help even more. I was looking at the driver sources in
OpenGrok, and (if I was looking at the same version) I thought I'd set
a few more break points. it looks like it's:
bge_attach()->bge_reset()->bge_chip_reset()->bge_asf_pre_reset_operations()
Hope this helps.
