alanc: fortunately intel popcount instruction operates on regular integer registers, but it's not found on cpus older than nehalem (intel) or barcelona (amd). (and I've got one that's too old that I still occasionally use as a test machine).

and no linker capabilities in the kernel :P

[illumos-gate] 18311 format: enable smatch -- Toomas Soome <tsoome⊙mc>

hrm.. is it jsut 'no one's done it yet' to add a topo module to enumerate NIC leds, or is there some other reason we don't (when present)?

At least for me, the former.

[illumos-gate] 18411 format: remove __STDC__ -- Toomas Soome <tsoome⊙mc>

[illumos-gate] 18413 zfs: spa_sync_upgrades() should only take lock when needed -- Toomas Soome <tsoome⊙mc>

given we don't have man pages for the kernel secpolicy_xxx() functions, would those not be considered DDI interfaces (at least at the moment)?

Correct, only drv_priv() is considered DDI.

the DDI-ness of things is kind of a mess, and I wouldn't worry too much about straying if I was in illumos-gate

though some day I'd love to go through and look at the parts everyone cheats on and just promote them.

but we've had problems in the past where people misguided tried to treat the DDI as gospel, and don't do that, it's bad for you

If you have a list of some of them, Rich, happy to go through and work on some of that.

I don't unfortunately, I just sometimes run into stuff on the arm side where I ask people to look for the DDI way and then there isn't one :)

Okay, happy to work on gaps too.

the ice NIC can generate log messages from the HW (or I guess the embedded proc inside the nic), and given the rather large complexity i thought it would be nice to have some ioctls to enable emitting those (like the freebsd driver)... but also been trying to keep the interfaces used tidy w/ mapfiles

rmustacc: the most recent thing I remember being generally useful (question mark?) was a "compatible" matcher

so if there is anything needed outside of mac/ddi/random it's essentialyl documented in one place

but the precedent for NIC ioctls seems to be having net_config

(don't know if that's a good precedent or not, but it is what it is)

i finished getting the flow director and flex pipelines for RSS (kinda gave up and just ported the fbsd code -- there's likely opportuntiy to simplify things a fair amount for our use case, but trying to tease apart all of that is going to take waaaay to long)

(just ported those bits of functionality)
