nat 204972d45c Audio mmap now works with all devices as hw->mappage is no longer used. 
Audio ring buffers are now uvm objects.

This was made possibile with help from christos@ and much help and mmap
functions written by riastradh@.

joerg 4f77b889d0 Extend the mmap(2) interface to allow requesting protections for later 
use with mprotect(2), but without enabling them immediately.

Extend the mremap(2) interface to allow duplicating mappings, i.e.
create a second range of virtual addresses references the same physical
pages. Duplicated mappings can have different effective protections.

Adjust PAX mprotect logic to disallow effective protections of W&X, but
allow one mapping W and another X protections. This obsoletes using
temporary files for purposes like JIT.

Adjust PAX logic for mmap(2) and mprotect(2) to fail if W&X is requested
and not silently drop the X protection.

Improve test cases to ensure correct operation of the changed
interfaces.

ozaki-r 1300188462 Introduce MKSTRIPSYM build option 
If it's yes, all local symbols of shared libraries are stripped
(default). If it's no, only temporary local symbols are stripped;
for example, symbols of static functions are kept. Keeping such
symbols is useful on using DTrace for userland libraries and
getting a backtrace from a rump server loading modules (shared
libraries).

Proposed and discussed on tech-kern and tech-toolchain

nat c65925dd1f Improved mixing function - more expensive in cycles though. 
hw.driverN.saturate is no longer needed and has been removed.

Mixing function thanks to jmcneill@.
 2017-04-17 22:40:06 +00:00
nat fda69a13cf hw.driverN.saturate bool->integer (default 16). 
This means for a greater number than 16 (or user set value) the saturate
function is turned off.  Results in better listening if a large number of
channels are in use.

kamil bce1cecb2e Add new documentation locking(9) 
It's a document from June 2015.

DESCRIPTION
     The NetBSD kernel provides several synchronization and interrupt control
     primitives.  This manpage aims at giving an overview of these interfaces
     and their proper application.  This document includes also basic kernel
     thread control primitives and rough overview of the NetBSD kernel design.

Part of interfaces are missing, like new mechanisms for networking SMP,
as this documentation page predates them.
