thorpej | Add _KERNEL guards around most of the definitions in these files.
|
| 1.38 |
| 16-Jan-2024 |
thorpej | Fix computation of the appropriate auto-vector interrupt level to use
for the DMA controller by tracking all of the DIO devices that have
"ISRPRI_BIO" interrupt handlers, and finding the highest auto-vector
level among them and informing the DMA controller.
Previously, in a post-flattening world, the DMA controller was always
told to interrupt at lev5, which is fine I guess although definitely not
ideal, but would not work on aaaancient HP320 Rev A DMA boards. To that
effect, print a warning if a Rev B DMA board ends up at ipl != 3 (we can't
differentiate between a Rev A and a Rev B board).

| 1.37 |
| 16-Jan-2024 |
thorpej | Switch hp300 over to the common interrupt dispatch code.
XXX There are still some things to fix up here, but it's no worse
than it was before (the problems date back to when we flattened
the device interrupt levels into IPL_VM).
|
| 1.36 |
| 11-Jul-2023 |
riastradh | hp300/intr.h: Put most of this under #ifdef _KERNEL.
Only ipl_cookie_t really needs to be exposed now, for crash(8).
|
| 1.35 |
| 11-Jul-2023 |
riastradh | hp300/intr.h: Fix missing includes.
|
| 1.34 |
| 06-Mar-2011 |
tsutsui | branches: 1.34.86;
Remove trailing spaces.
|
| 1.33 |
| 09-Apr-2009 |
tsutsui | branches: 1.33.4; 1.33.6;
Include <sys/evcnt.h> instead of <sys/device.h> for struct evcnt.
<sys/device.h> now requires <sys/mutex.h> for struct device_lock, and
<machine/mutex.h> requires <machine/intr.h> for ipl_cookie_t, so
including <sys/device.h> from <machine/intr.h> causes recursive dependency.
|
| 1.32 |
| 21-Dec-2008 |
tsutsui | branches: 1.32.2;
Remove obsolete code for old software interrupt emulation.
The MI softint(9) handles it in the kernel threads nowadays.
Note "Emulation of VAX REI instruction" is still there to handle ASTs.
|
| 1.31 |
| 22-Jun-2008 |
tsutsui | branches: 1.31.4; 1.31.6;
Make cpu_intr_p() inline.
|
| 1.30 |
| 22-Jun-2008 |
tsutsui | Don't recompute an ipl level for IPL_VM during or after cpu_configure(9)
and use a static and possible highest ipl value (ipl 5) for IPL_VM
so that we can put ipl2psl_table[] conversion into makeiplcookie(9),
which could be called before cpu_configure(9).
Fixes "panic: sbappendaddr" on NFS load.
|
| 1.29 |
| 15-Jun-2008 |
tsutsui | Unify splraiseipl(9) implementation among m68k ports as per
suggestion from isaki@ on port-m68k.
For hp300:
- use ipl2psl_table[] for makeiplcookie() conversion
- use uint16_t for ipl2psl_table[]
|
| 1.28 |
| 28-Apr-2008 |
martin | branches: 1.28.2; 1.28.4;
Remove clause 3 and 4 from TNF licenses
|
| 1.27 |
| 28-Jan-2008 |
tsutsui | branches: 1.27.6; 1.27.8; 1.27.10;
- account idepth in a clock interrupt handler too
- use idepth for CLKF_INTR()
|
| 1.26 |
| 03-Dec-2007 |
ad | 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.
|
| 1.25 |
| 17-Oct-2007 |
garbled | branches: 1.25.2;
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.
|
| 1.24 |
| 15-Oct-2007 |
tsutsui | Add IPL_SERIAL definition since MI com(4) now requires it for mutex(9).
|
| 1.23 |
| 11-Mar-2007 |
thorpej | branches: 1.23.8; 1.23.16; 1.23.18; 1.23.20;
- Shrink ipl_cookie_t from 32-bits to 16-bits (large enough to hold
an SR value or an IPL_* constant).
- Take advange of the smaller ipl_cookie_t to shrink kmutex_t from
16 bytes to 8 bytes by overlapping storage where possible.
- Implement a RAS-based _lock_cas() for mc68010 systems (Sun2). See
sun68k/sun68k/isr.c.
Tested on various m68k platforms, but NOT Sun2. In any case, at least
Sun2 compiles now.
|
| 1.22 |
| 04-Mar-2007 |
tsutsui | branches: 1.22.2;
Remove #ifdef _KERNEL since this file is no longer exported.
|
| 1.21 |
| 04-Mar-2007 |
tsutsui | Hide #include <m68k/softintr.h> inside #ifdef _KERNEL in <machine/intr.h>
to avoid exporting unnecessary files to userland.
Should fix build.sh failure, which was pointed out by isaki@.
XXX: which userland program would require contents of <machine/intr.h>?
|
| 1.20 |
| 04-Mar-2007 |
tsutsui | Make hp300 use common m68k/softintr.c.
|
| 1.19 |
| 16-Feb-2007 |
ad | branches: 1.19.2;
Remove spllowersoftclock() and CLKF_BASEPRI(), and always dispatch callouts
via a soft interrupt. In the near future, softclock will be run from process
context.
|
| 1.18 |
| 15-Feb-2007 |
tsutsui | Fix an indent in the previous.
|
| 1.17 |
| 10-Feb-2007 |
tsutsui | Rename _IPL_SOFT* macro to SI_SOFT* to sync with other m68k ports.
|
| 1.16 |
| 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.
|
| 1.15 |
| 11-Dec-2005 |
christos | branches: 1.15.20; 1.15.22;

u_intNN_t -> uintNN_t
|
| 1.13 |
| 08-Nov-2003 |
tsutsui | Switch DCA and APCI serial devices to use MI com(4) driver.
DCA is tested on HP362 and HP382 with serial console,
but APCI on HP4xx is not tested yet.

softintr(9) interface for hp300
|
| 1.11 |
| 13-Apr-2001 |
thorpej | branches: 1.11.2; 1.11.8;
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.
|
| 1.10 |
| 14-Jan-2001 |
thorpej | branches: 1.10.2;
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).
|
| 1.9 |
| 22-Aug-2000 |
thorpej | Add spllock(). See spl(9) for details.
|
| 1.8 |
| 21-Aug-2000 |
thorpej | Make sure we provide splsched() as described in spl(9).
|
| 1.7 |
| 05-Aug-1999 |
thorpej | branches: 1.7.2;
Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
|
| 1.6 |
| 01-Aug-1999 |
thorpej | Store computed PSL values in an array indexed by abstract interrupt
level, rather than individual shortwords.
|

kleink | Slightly rearrange the SSIR inline assembly implementation in order to avoid
making assumptions on C symbol name prefixes.
|
| 1.4 |

kleink | branches: 1.4.10;
Spell `interrupt' correctly.
|

jtc | Fix tipo inherited from old version of TNF copyright template.
|
| 1.2 |
| 24-Jul-1997 |
scottr | branches: 1.2.2;
Use optimized _splraise() implementation, from mac68k/intr.h
|
| 1.1 |
| 14-Apr-1997 |
thorpej | Rearrange the interrupt code slightly:
- place all interrupt-related macros, prototypes, etc. into <machine/intr.h>,
like other ports.
- rename isrlink/isrunlink/isrinit, etc. intr_establish/intr_disestablish/
intr_init, etc., and move to intr.c for naming consistency.
- don't call intr_init() twice.

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.

Now init_main.c compiles though GENERIC still doesn't build due to
"initialization discards qualifiers from pointer target type" warnings
by newer gcc4.

tsutsui | Reorganize IPL macros for proper splraiseipl() implementation:
- merge HP300_IPL_* and IPL_* macros
- prepare independent _IPL_SOFT_* macro to determine softintr(9) handlers
- rename hp300_ipls[] array to hp300_ipl2psl[]
- then use these macro for makeiplcookie() and splraiseipl()
Tested on HP382.

For ipl_cookie_t and __cpu_simple_lock_t.
evbarm/intr.h: Define ipl_cookie_t before including ARM_INTR_IMPL.
Otherwise arm/mutex.h doesn't work, due to a cyclic dependency which
should really be fixed.
opencrypto/cryptodev.h: Fix includes.
- Move sys/condvar.h under #ifdef _KERNEL.
- Add some other necessary includes and forward declarations.
- Sort.
hp300/intr.h: Fix missing includes.
linux/idr.h: Need <sys/mutex.h> for kmutex_t.
amiga/intr.h: Don't define spl*() functions if !_KERNEL.
This is used by crash(8) now, and what's important is ipl_cookie_t.
cesfic/intr.h: Expose ipl_cookie_t to userland for crash(8).
cesfic/intr.h: Expose ipl_cookie_t to userland only with _KMEMUSER.
Probably not necessary but let's be a little more cautious about
this.
atari/intr.h: Expose ipl_cookie_t with _KMEMUSER for crash(8).
arm/cpu.h: Need sys/param.h for COHERENCY_UNIT.
Nix machine/param.h -- not meant to be used directly, pulled in by
sys/param.h.
Move the definition of ipl_cookie_t out of the kernel-only sections,
some _KMEMUSER applications need it.
ddb: Cast pointer to uintptr_t first before db_expr_t.
hppa/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
luna68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
mvme68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
news68k/intr.h: Fix includes. Put some definitions under _KERNEL.
next68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
sys/ksem.h: Hack around fstat(8) abuse of _KERNEL.
sun68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
vax/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
x68k/intr.h: Put functions under _KERNEL so crash(8) can use this.
Make ipl_cookie_t visible for _KMEMUSER userland applications.
fix editor mishap in previous
Explicitly include <sys/mutex.h> for kmutex_t.
Replace kmutex_t * (which may be undefined here) with struct kmutex *,
suggested by Taylor.
hp300/intr.h: Put most of this under #ifdef _KERNEL.
Only ipl_cookie_t really needs to be exposed now, for crash(8).
mac68k/intr.h: Expose ipl_cookie_t to _KMEMUSER for crash(8).
Make inclusion of sys/intr.h explicit for spl*.
fix hppa and vax builds.
machine/lock.h isn't necessary for __cpu_simple_lock_t, it's in
sys/types.h. avoids cpu_data.h vs sched.h include order issues.
move the hppa ipl_t typedef with the moved usage of it.
machine/mutex.h: Sprinkle sys/types.h, omit machine/lock.h.
Turns out machine/lock.h is not needed for __cpu_simple_lock_t, which
always comes from sys/types.h. And, really, sys/types.h (or at least
sys/stdint.h) is needed for uintN_t and uintptr_t.
ddb: Cast pointer to uintptr_t, then to db_expr_t.
Avoids warnings about conversion between pointer and integer of
different size on some architectures.
re-fix hppa builds.
this file uses __cpu_simple_lock(), not just the underlying type,
so it does need machine/lock.h.
Break cycle by using `struct kmutex *' instead of `kmutex_t *'.
sys/sched.h included sys/mutex.h
which includes sys/intr.h
which includes machine/intr.h
which on cats includes arm/footbridge/footbridge_intr.h
which includes arm/cpu.h
which includes sys/cpu_data.h
which includes sys/sched.h
But there was never any real need for sys/mutex.h in sys/sched.h,
because it only uses pointers to the opaque struct kmutex. Cycle
broken by using `struct kmutex *' instead of pulling in sys/mutex.h
for the definition of kmutex_t.
Side effect: This revealed that sys/cpu_data.h needed sys/intr.h
(which was pulled in accidentally by sys/mutex.h via sys/sched.h) for
SOFTINT_COUNT. Also revealed some other machine/cpu.h header files
were missing includes of sys/mutex.h for kmutex_t.
ia64: Need sys/types.h for u_int, vaddr_t; sys/mutex.h for kmutex_t.
explicitly include no longer implicitly included sys/mutex.h.
arm/xscale: Use sys/bitops.h fls32 - 1 instead of 31 - __builtin_clz.
Sidesteps namespace collision with `#define bits ...' in net/zlib.c.
complete the previous - there were two calls to find_first_bit() to fix.
arm/xscale: Missed a spot with previous find_first_bit commit.
evbarm/g42xxeb: Fix off-by-one in previous.
The original find_first_bit(x) was 31 - __builtin_clz((uint32_t)x),
which is equivalent to fls32(x) - 1, not to fls32(x).
Note that fls32 is 1-based and returns 0 for x=0.
