08:26:24 <carba> I did some investigation on Solaris 11.4 guest deadman cyclic panic on Omnios Bhyve. In the moment of panic the deadman_counter on the next CPU is 301sec back. All CPU threads are idle. It seems the root cause is, that the Solaris guest uses:  APIC_TIMER_MODE_ONESHOT   0x0   /* One-Shot */. I guess this is not the default, instead is set because the CPU do not report the TSC feature as available (cpi_std[1].cp_ecx = 0xfede7a17) & 0x1000
08:26:24 <carba> 00. It is possible to change/choose an other CPU type in Bhyve on Omnios? Illumos guest uses apic_timer_preferred_mode = 2 (TSC) anyway.
08:37:39 <Woodstock> carba: i'm working on something for modifying cpuid features, but no idea if this will help you in any way with this problem
09:08:35 <otis> to help with live migration between nodes?
09:25:42 <carba> Btw: Illumos deadman does not compare the deadman_counter of next/other CPU with the own counter.
09:31:14 <Woodstock> otis: that's the long term goal
09:34:14 <otis> Woodstock: fingers crossed.
09:46:46 <carba> Does Bhyve have counters for steal-time or scheduling delays of vcpus?

16:03:07 <jbk> is there a way to turn off the auto-unload of unused kernel modules on debug builds?
16:04:15 <jbk> (or at least mark specific modules to not unload)
16:04:48 <jbk> though I suppose I might be able to just have _fini() return 1 for testing
16:05:07 <jbk> (so I don't have to race w/ te dtrace before the symbols disappear :P)
16:13:41 <tsoome>  /* Don't auto unload modules on if moddebug flag is set */
16:13:53 <tsoome> moddebug & MODDEBUG_NOAUL_DRV
16:25:21 <denk> tsoome knows everything, maybe he is an AI bot? :)
16:25:42 <tsoome> most certainly do not know everything.
16:26:21 <tsoome> I was once searching same thing.... ;)
17:10:34 <jbk> the trick is often knowing where to look :)
19:39:02 <richlowe> moddebug is full of goodies
19:39:05 <richlowe> the 1 bit is great too
19:41:43 <richlowe> jbk: something else good in an emergency, with an eminently forgettable name: `mtc_off` (and `mdi_mtc_off`)
19:41:58 <jbk> multi-threaded config?
19:42:00 <richlowe> mtc - "multi threaded config", it's what fans out module load etc.
19:42:06 <jbk> ahh
19:42:25 <jbk> thankfully this is just for working on the ice driver
19:42:54 <jbk> it doesn't panic, but when something's not working, it's often too quick to unload
19:43:09 <jbk> so just need to have it be sticky so it's easier to dtrace
