During normal operation, the PN533 chip may corrupt its USB configuration,
interface and endpoint descriptors. The device descriptor remains unaffected.
Since the descriptors are documented to be immutable, we can work around
the problem by providing hard-coded descriptors instead of pulling them
from the device.
Userland implementation such as NFC tools' libnfc use the same approach,
but this kernel quirk is still necessary so that the device can be
attached on reboot, after its USB descriptors got corrupted.
For some reason, fabs lives in libc, not in libm, and our tests now
detect when fabs or fabsl is missing from libm. For those ports that
sometimes have long double and sometimes don't, make it conditional.
Still missing: fabs _and_ fabsl on ia64. Need help from an itanium
wizard! Other portmasters: Please take a look and see if I missed
any ports that might have long double where this alias will not work.
Skip CDs when looking for install targets (we do not support installing
onto a blueray with UDF).
Fix search for the default CDROM device and the CD we booted from
for ports with nonstandard CDROM device names.
provides support for hardware-accelerated virtualization on NetBSD.
It is made of an MI frontend, to which MD backends can be plugged. One
MD backend is implemented, x86-SVM, for x86 AMD CPUs.
We install
/usr/include/dev/nvmm/nvmm.h
/usr/include/dev/nvmm/nvmm_ioctl.h
/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h
And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).
NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.
Sent to tech-kern@ a month ago. Validated with kASan, and optimized
with tprof.
Similarly, when hardware NaN propagation is available, disable
default-NaN substitution.
This enables IEEE 754 semantics on any hardware that supports it by
default. Programs that want flush-to-zero or default-NaN substitution
can enable them explicitly.

The x87 hardware uses a bad approximation to pi for argument
reduction, and consequently yields bad answers for inputs near pi or
pi/2.
Tweak one tanf test whose doubly rounded output is a little too far
from the correct answer on the doubly rounded input.
- Fix up last few digits of a lot of known-answer tests.
Confirmed with GNU mpfr to 200 bits of precision and cross-checked
with whatever libm Ubuntu ships with.
- Test relative error, not absolute error.
- Set bounds in terms of *_EPSILON, not magic numbers.
*_EPSILON is twice the largest relative error of a correctly
rounded operation, and equal to the largest relative error of an
operation with up to 1ulp error.
Most of the operations we're testing are not correctly rounded, but
they ought to be no more than 1ulp away. For the few cases where
that's not a priori clear (like comparing cbrt and pow(x, 1/3)),
use twice *_EPSILON to allow some leeway.
- Write the success condition positively as error <= eps.
This comes out false if the result is a NaN, meaning failure. In
contrast, if we write error > eps for the _failure_ condition, then
if the result is a NaN, it will also come out false, but meaning
success, which is not what we want.
- Fix the trigonometric test cases near bad spots.
sin(pi - d) for nonzero d is not zero; it is d + O(d^3). pi is not
a floating-point number, so these results should be approximately
the nonzero error of our approximation to pi. Likewise with
cos(pi/2 - d) and tan(pi + d).
(Yes, I know the sin _function_ is ill-conditioned near pi so you
shouldn't pass approximate inputs near there, but that's separate
from whether a sin _implementation_ gives an answer that is wrong
by quintillions of ulps.)
Since on x86 (i386 and amd64 alike) we currently use x87 hardware
trigonometric instructions, which are bad, these are marked xfail
on x86 for now until we switch to software implementations (coming
soon to a repository near you).
- Use %.8g, %.17g, %.35g to print float, double, long double in failures.
This should be enough to identify the problematic outputs and/or
reproduce the computation, even if long double is binary128 with
115 bits of precision.
If there are any new libm test failures after this, tell me what
architecture you're on and send me the atf output and I'll try to
figure it out.
This way they test libm, not whatever the compiler does.
We should _also_ have automatic integration tests for what the
compiler does, as a separate thing.

From hannken@
When puffs_cookie2vnode() misses an entry and vrele() it operations
puffs_vnop_reclaim() and puffs_vnop_fsync() get called with a VNON
vnode.
Do not notify the server in this case as the cookie is stale.
ioctl was passed through ifioctl_common, because the case falls through
to the SIOCSIFFLAGS case. The common handler however doesn't implement
SIOCINITIFADDR, so an attempt to configure plip always failed with ENOTTY.
