riastradh | rnd(9): Adjust IPL of locks used by rndsource callbacks.
These no longer ever run from hard interrupt context or with a spin
lock held, so there is no longer any need to have them at IPL_VM to
block hard interrupts. Instead, lower them to IPL_SOFTSERIAL.

tls | branches: 1.37.6;
Convert the entropy pool framework from pseudo-callout-driven to
soft interrupt driven operation.
Add a polling mode of operation -- now we can ask hardware random number
generators to top us up just when we need it (bcm2835_rng and amdpm
converted as examples).
Fix a stall noticed with repeated reads from /dev/random while testing.

drochner | branches: 1.35.6;
Use pci_aprint_devinfo(9) instead of pci_devinfo+aprint_{normal,naive}
where it looks straightforward, and pci_aprint_devinfo_fancy in a few
others where drivers want to supply their own device names instead
of the pcidevs generated one. More complicated cases, where names
are composed at runtime, are left alone for now. It certainly makes
sense to simplify the drivers here rather than inventing a catch-all API.
This should serve as as example for new drivers, and also ensure
consistent output in the AB_QUIET ("boot -q") case. Also, it avoids
excessive stack usage where drivers attach child devices because the
buffer for the device name is not kept on the local stack anymore.

Disgusting Xbox hack;
The "pci0 dev 1 function 2" aka "System Management" on the nForce chipset
isn't detected on the Xbox. If XBOX is defined and arch_i386_is_xbox is
true, force intrline to 12 and map the system management IO space at
0x8000. We can now call iic_smbus_intr when a system management interrupt
takes place.
While we're here, make amdpm_smbus honour the I2C_F_POLL flag.
The Xbox no longer resets when you press the eject button.

Revert previous change, which was wrong. As Enami points out, we really do
want the NO_ESTIMATE flag here, because if the source doesn't have it,
rnd_add_data will *use the time the data was added directly as entropy*,
which is not a good idea either for a hardware RNG that works like this
one (periodically polled by the driver) or, really, like any other that I've
seen, because even for "interrupt when ready" RNGs the data rate (and thus
interrupt time) will vary only slightly for a given RNG configuration over
time, if at all.
The data we add _is_ counted into the pool estimage because we directly
pass in an entropy estimate.
The overloading of the NO_ESTIMATE flag with this meaning seems, to me, like
a design bug (albeit easily fixed) in the rng interface; but until that's
changed, we need to use it here.
|
| 1.6 |
| 12-Aug-2003 |
tls | Remove RND_FLAG_NO_ESTIMATE and comment claiming we can't estimate (which
means "count", in this context) the entropy we're adding because we poll the
device periodically. Sure, we poll it periodically, but it's a hardware
RNG -- the data returned should be random no matter when we read the
register!

4) define RND_FLAG_DEFAULT: RND_FLAG_COLLECT_TIME|
RND_FLAG_COLLECT_VALUE|RND_FLAG_ESTIMATE_TIME
5) Make entropy harvesting from environmental sensors a little more generic
and remove it from individual sensor drivers.
6) Remove individual open-coded delta-estimators for values from a few
places in the tree (uvm, environmental drivers).
7) 0 -> RND_FLAG_DEFAULT, actually gather entropy from various drivers
that had stubbed out code, other minor cleanups.
