thorpej f3d9d1ac8a Use the common 82c693 access functions to read/write the ELCR. 2000-06-06 03:10:13 +00:00
thorpej b0ce38fd8a Switch to the new `evcnt' mechanism for counting interrupts. Maintain
a per-CPU interrupt counter for clock, device, and interprocessor
interrupts.

cgd cffb580806 Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).

mycroft cf3085176e Nuke all the code associated with the INITIALLY_LEVEL_TRIGGERED() lossage, and
instead register a shutdownhook to restore the PIC state.

ross 02140cb46f Fix the 16-bytes-of-death bug by generating specific-EOI cycles during
sio_intr_setup().

thorpej 92fa3a68ad In sio_intr_disestablish, also make sure that IRQs 0, 1, 8, and 13
default to edge-triggered, just like in the setup.

thorpej 0b60fda7c8 Implement sio_intr_disestablish(), and ensure that an initially-enabled
interrupt is never disabled and an initially-level-triggered interrupt
never becomes untyped.

matt 9c2e213217 Add sio_intr_alloc (copied from i386's isa_intr_alloc) for PCMCIA. 1998-05-23 18:35:56 +00:00
thorpej 164f56220e Add support for the Cypress CY82C693 PCI-ISA bridge. This bridge is more or
less like an Intel SIO except that the ELCR registers are accessed differently
than on the Intel SIO.

XXX This code needs to be split up into bridge front-end and PIC back-end
XXX pieces.

thorpej 693b3e7262 Nuke the idea of <machine/options.h>. It completely defeats the purpose
of fine-grain option dependencies.

cgd 90789b53dd by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory.  (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)

cgd a60b90caa9 clean up NetBSD RCS ID strings, include machine/options.h 1997-04-07 02:01:16 +00:00
cgd ccc668e0d7 use the new common chained-interrupt support code. 1996-11-17 02:05:26 +00:00
cgd 6c9cb4aa9b compile cleanly with:
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes -Wcast-qual
1996-11-13 21:13:04 +00:00
cgd 1b03f1bca7 update for new bus.h macros. bus_io_* and bus_mem_* integrated into
single bus_space_* framework.  Unfortunately, bus_space_{read,write}_*
operations still imply barriers.  That will change soon.

cgd e295ad51df clean up stray interrupt handling a bit. 1996-08-15 22:17:44 +00:00
cgd 644f74f9f2 (1) Clean up interrupt handling slightly. 1996-07-14 04:08:41 +00:00
cgd ebe3a58f01 pull down changes from NetBSD 1.2 release branch:
>Update for present reality (function names), clean up a bit (printfs,
>"panic: foo XXX"), and fix a couple of printf format specified bugs
>(which were normally #if 0'd out).  Inspired by Multia/UDB support
>changes sent by Matt Thomas.
and:
>changes from Matt Thomas so that the Multia/UDB can attach its
>'com' interrupts, cleaned up some.  Basically: if sharing type of
>new interrupt is different than what the hardware is currently set up
>for (e.g. requesting edge-triggered and the hardware is set up by
>the PROM for level triggered) and there are no interrupt handlers on
>that line already, warn about it and use the hardware type that the
>line was already set for (to avoid making the console blow up on
>reboot).  If same circumstances but there is already a handler, panic
>as before.

cgd 37ec86f0cc avoid lots of upper-case letters in interrupt names. prettier that way. 1996-06-05 03:38:02 +00:00
cgd f32c94e82c note that these IRQs are ISA IRQs 1996-04-13 00:22:58 +00:00
cgd 576c769331 clean up copyrights and RCS IDs 1996-04-12 06:07:05 +00:00
cgd 98c183ff49 remove (hack) version of isa_intr_establish() 1996-04-12 05:41:50 +00:00
cgd a52d1c3efe clean up for new ISA and 'bus' code, etc. 1996-04-12 02:11:22 +00:00
mycroft 3da4b2a160 The IST_* and IPL_* constants are not bus-specific; don't treat them as such.
Change splimp -> splnet in Ethernet, ARCnet, and FDDI drivers.

cgd deb4082f80 wholesale update from my NetBSD/Alpha source tree. Includes:
Support for AXPpci CPUs,
	Support for AlphaStation 600 CPUs,
	new boot block structure, which requires an 'installboot'
	    program and works a lot like the NetBSD/sparc boot blocks.
