been lightly tested with unmodified networking applications with both
the client and server on a 64bit le host. Unlike the standard Linux
compat libs where args and syscalls are swizzled around, this compat
lib only massages the arg data types due to the assumption that syscall
numbers come from librumpclient (via librumphijack) and therefore match
the native NetBSD numbers.
dynamically loaded module (.so) supplementing npfctl(8) and a kernel
module. Move normalisation and logging functionality into their own
extensions. More improvements to come.
lock), we need to take the CPU interlock before releasing the CPU.
Otherwise other threads can be scheduled before we get the interlock,
leading to e.g. missed condvar wakeups. This affected only "locks_up.c"
locking (nomen est omen?).
Also, remove various __predicts since they don't have a positive
performance impact in any setup.
(map == module_map). Otherwise, use the malloc hypercall. This avoids
relying on the platform's mmap() to be able to return arbitrarily
alignment memory.

- NPF tables: update regression tests, improve npfctl(8) error messages.
- Fix few bugs when using kernel modules and handle module autounloader.
- Few other fixes and misc cleanups.
- Bump the version.
initial work, and every one else who has tested things for me.
this is largely my fault at this point :-)
the main changes are something like:
- usbd_bus_methods{} gains a get_lock() to enable the
host controller to provide a lock for the USB code.
if the lock isn't provided, old-style protection is
(partially) applied.
- ehci/ohci/uhci have been converted to the new
interfaces, including mutex/cv/etc conversion.
- usbdivar.h contains a discussion about locking and
what locks are held for which method calls. more
to come for usbdi(9) here.
- audio drivers (uaudio, umidi, auvitek) have been
properly SMPified now that USB is ready.
- scsi drivers have been modified to take the kernel
lock explicitly before calling into scsi code.
- usb pipes are associated with a lock, that is the
same as the controller lock. (this could be split
up further in the future.)
- several usbfoo_locked() or usbfoo_unlocked()
functions have been added to the usbdi(9) to
enable functionality with or without the USB
lock (per controller) already being held.
the TODO.usbmp file has specific details on what is left to
do, including what device-specific changes should be done now
that the whole framework is ready.
caches, merge together pool_drain_start() and pool_drain_end() into
bool pool_drain(struct pool **ppp);
"bool" value indicates whether reclaiming was fully done (true) or not (false)
"ppp" will contain a pointer to the pool that was drained (optional).

- ubc_uiomove: avoid the re-lock dance, since the lock is shared these days.
- uvm_aio_aiodone: acquire the lock before modifying the page flags.
