 1.20  26-Apr-2025  tsutsui Move ipl_sr_map to model-specific file and add IPL_DDB entry.

This will help adding support for other mipsco systems such as
the RC3240 eventually.

Patch from Miod Vallat.
 1.19  20-Feb-2011  matt Merge forward matt-nb5-mips64
Adapt to new interrupt/spl framework
 1.18  13-Apr-2009  he branches: 1.18.4; 1.18.6; 1.18.8;
Include <sys/evcnt.h> instead of <sys/device.h> to break circular
dependency graph.
 1.17  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.16  03-Dec-2007  ad branches: 1.16.18; 1.16.26; 1.16.32; 1.16.36;
Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
 1.15  17-Oct-2007  garbled branches: 1.15.2;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.14  17-Jun-2007  tsutsui branches: 1.14.8; 1.14.10;
Move declaretions of _spl*() and _{clr,set}softintr() functions
(which are in mips/locore.S) into <mips/locore.h>
from various MD files.
 1.13  16-Feb-2007  ad branches: 1.13.6; 1.13.8; 1.13.14;
Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts
via a soft interrupt. In the near future, softclock will be run from process
context.
 1.12  21-Dec-2006  yamt merge yamt-splraiseipl branch.

- finish implementing splraiseipl (and makeiplcookie).
http://mail-index.NetBSD.org/tech-kern/2006/07/01/0000.html
- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
 1.11  11-Dec-2005  christos branches: 1.11.20; 1.11.22;
merge ktrace-lwp.
 1.10  09-Jun-2005  he branches: 1.10.2;
Prefix variables in a macro with an underscore to avoid shadowing problems.
 1.9  14-Jan-2002  soren branches: 1.9.16;
Remove __HAVE_GENERIC_SOFT_INTERRUPTS #ifdef.
 1.8  15-Sep-2001  wdk branches: 1.8.4;
spllpt() for ISA Bus printer support
 1.7  13-Apr-2001  thorpej branches: 1.7.2; 1.7.4;
Remove the use of splimp() from the NetBSD kernel. splnet()
and only splnet() is allowed for the protection of data structures
used by network devices.
 1.6  30-Mar-2001  wdk New data structures and prototypes for MI softintr support
 1.5  14-Jan-2001  thorpej branches: 1.5.2;
Make sure everybody has an splvm() and equate it with splimp() (splimp()
is the historical name for this interrupt level, and the historical name
is going to go away in the near future).
 1.4  22-Aug-2000  thorpej branches: 1.4.2;
Add spllock(). See spl(9) for details.
 1.3  21-Aug-2000  thorpej Make sure we provide splsched() as described in spl(9).
 1.2  15-Aug-2000  wdk * Tidy up interrupt handlers by implementing an intr_establish()
handler to hook up device interrupts and softc callbacks.

Suggested by: Jason Thorpe and Toru Nishimura

* Fixup the indenting in a few places to conform to NetBSD style
 1.1  12-Aug-2000  wdk Initial commit of port to MIPS Computer Systems RC3xxx systems.
Currently supports the RC3230
 1.4.2.4  21-Apr-2001  bouyer Sync with HEAD
 1.4.2.3  18-Jan-2001  bouyer Sync with head (for UBC+NFS fixes, mostly).
 1.4.2.2  20-Nov-2000  bouyer Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.
