While doing some new hme/qfe driver testing on a 2x400MHz ultra2
tonight, I noticed something odd - lots of cross-calls while this box
was sitting idle. Roughly 100/second. A quick 20 second dtrace
revealed the outlaying stack:
SUNW,UltraSPARC-II`send_one_mondo+0x14
SUNW,UltraSPARC-II`send_mondo_set+0x1c
unix`xt_all+0xac
SUNW,UltraSPARC-II`do_scrub_ecache_line+0xa4
genunix`callout_list_expire+0x5c
genunix`callout_expire+0x14
genunix`callout_realtime+0x14
genunix`cyclic_softint+0xb4
unix`cbe_level1+0x8
unix`intr_thread+0x168
2010
Maybe I've just never noticed this before, having not worked on this
hardware since I last powered it down years ago, but is the E$
scrubber supposed to be triggering so many xcalls?
