mycroft d7107be1c9 Fix a condition where we might keep interrupts blocked while servicing a soft
interrupt.
Fixes serial port silo overflow problems.

mycroft b2038a332d Import interrupt priority changes from com patches:
* Make it a strict hierarchy.  (It was close anyway).
* Add `serial' and rename `softtty' to `softserial'.
* Make soft interrupts a bit less special-case.
1997-02-28 16:24:03 +00:00
mycroft 135b1cea1f Remove incomplete and unused `fast' vector code. 1996-11-20 14:09:07 +00:00
jonathan a935a72af3 Fix cut-and-paste errors. 1996-11-20 11:37:52 +00:00
jonathan 584f698f2c * Add old-style vmstat -i interrupt counters for normal and stray interrupts.
Interrupts for irqs with handlers are counted as normal, even if none of
  the handlers claim the interrupt.
  Should all be redone with hierarchical event counters. that count
  hardware events and invocations of each handler separately.

* Increment cnt.v_intr for normal interrupts (bugfix).

mycroft ba1353b388 Stylistic changes. 1996-01-07 21:29:47 +00:00
mycroft 0696821419 Deal with GCC's dead code elimination being suboptimal. 1996-01-07 03:59:28 +00:00
mycroft 19914b6e10 Build the frame for recursive interrupts manually, and make sure to disable
interrupts to avoid races.
1996-01-07 02:02:28 +00:00
mycroft af7265051f The previous optimization only works for edge-triggered interrupts... 1995-05-08 18:00:20 +00:00
mycroft 6db4e1b58a By default, don't frob the ICU masks here. The software masking should
be sufficient.
1995-05-03 14:31:35 +00:00
mycroft 87b25c7f5c Update to match include files. Eliminate _ucodesel, _udatasel, and IdlePTD. 1995-05-01 08:25:30 +00:00
mycroft 4cd20dfe0a Move some comments to more appropriate places. 1995-04-22 00:30:47 +00:00
cgd 8a640328ed clean up several ISA device interfaces: autoconfiguration, header
inclusion, and interrupt configuration.  more work still needs to be done,
but it's getting better...
1995-04-17 12:06:30 +00:00
mycroft 79a1309e3c Remove Xwild; it's no longer used. 1994-11-18 22:22:40 +00:00
mycroft d35f08ffa6 isa.h -> isareg.h 1994-11-04 00:00:36 +00:00
cgd 022ee8f7fe new RCS ID format. 1994-10-27 04:14:23 +00:00
mycroft ee5cde2719 Oops; slight optimization to the previous. 1994-10-09 18:10:55 +00:00
mycroft f72ff16e5b Oops. Just fake %ebp; nothing else. 1994-10-09 14:45:40 +00:00
mycroft c9cb256e1d If DDB is configured, make a fake stack frame. 1994-10-09 14:43:00 +00:00
cgd baf4da3dd1 notdef out some debug code that no longer works 1994-05-23 02:25:09 +00:00
mycroft 2307cf7dc1 Only report `stray' interrupts if DEBUG, since they occur normally. 1994-04-18 22:23:32 +00:00
cgd e28a360811 keep vmstat happy. 1994-04-15 04:48:23 +00:00
mycroft 1296236880 Macroize some more constants. 1994-04-07 17:34:20 +00:00
mycroft 3f5e4f423f Implement dynamic IRQ configuration and IRQ sharing. Inline spl*() calls.
Reorganize and clean up the relevant code.
1994-04-07 06:48:19 +00:00
mycroft 9a9b1d99fa Minor code cleanup. 1994-04-02 08:04:26 +00:00
mycroft c857af00dc Clean up trap handling and macroize interrupt entry and exit code. From
magnum branch.
1993-12-19 06:58:12 +00:00
mycroft ea13c12adc From magnum branch:
Remove Jolitz's netisr kluge.  Make sure cpl == 0 really means base priority.
Other minor cleanup.
1993-12-17 00:10:06 +00:00
mycroft aee4b07b8a Add RCS identifiers, remove some completely useless RCS logs and patchkit
headers, and a few other insignificant changes.
1993-08-02 17:48:44 +00:00
cgd 77219acd07 change interrupt vector names to begin with "X" rather than "V", so we're
like every other BSD system on the planet...
1993-07-03 12:32:25 +00:00
cgd b8a46f69af Unless INTR_DEBUG is set, don't report all of the "random" event types.
also, unless INTR_DEBUG is set, make the internal branch labels for
the interrupt code be local labels, so profiling works OK.

andrew 172788b885 Fixed a typo. 1993-07-01 07:22:41 +00:00
mycroft ec3a442b59 Fix Andrew's real bug, and put back the FAST_VECTOR changes. 1993-07-01 00:20:19 +00:00
andrew 8d9d634680 Backed out the changes to the FAST_VECTOR code that were made in the
previous revision, as they apparently broke something.
1993-06-30 02:34:57 +00:00
andrew 4b741818d8 Neatened up the AUTO_EOI conditionals. FAST_VECTOR() now saves & restores
the ES register, just to be on the safe side (since ES is used in some
locore routines).
1993-06-27 05:15:06 +00:00
mycroft e534ec58ec Add support for other networks than INET. 1993-06-14 19:29:30 +00:00
cgd 276a05a454 apply patch 167, to fix some interrupt system bogosities 1993-06-06 05:06:50 +00:00
cgd 8a05b36058 incorporate Bruce Evans' interrupt changes, as hacked by Rod grimes,
for patchkit patch 158.  it appears to work well.
