remove unneeded placeholder

new RCS ID format.

compile needs to be kept in the distribution

Clean up deleted files.

Initialize host_stat and target_stat properly.

Simplify some sanity checks.

Add interrupt sharing types.

Numerous changes. Many bugs fixed, better autoconfig, a few new features.

No longer needs icu.h.

Change all of the uses of IRQ{0-15} and bit masks to use plain numbers
rather than bit shifting.

new RCS ID format.

Disable EISA reset, for now.

Remove diagnostic.

Redo some of the EISA config stuff.

Normalize.

Enable IRQ probing.

branches: 1.32.2;
Remove now-bogus cast.

lots of changes: prototype migration, move lots of variables, definitions,
and structure elements around. kill some unnecessary type and macro
definitions. standardize clock handling. More changes than you'd want.

change timeout/untimeout/wakeup/sleep/tsleep args to void *

Change structure member names.

Fix return values from some interrupt routines.

Implement dynamic IRQ configuration and IRQ sharing. Inline spl*() calls.
Reorganize and clean up the relevant code.

Increase ahb_send_mbox timeout.

Minor code cleanup.

Print out board revision info.

New SCSI system, based on Julian's more recent work.

Put controller target in scsi_switch.

Fix bug in last change.

Update to match config(8).

Updates to match config(8).

#include cpu.h in all files which use spl*().

Use KERNBASE, not 0xfe000000.

Fixed bug where with two or more SCSI controllers of the same type, you
could not have devices at the same ID on each bus.
This patch not directly applicable to magnum branch, which is using Julian's
new SCSI code.

Canonicalize all #includes, and add pio.h where appropriate.

branches: 1.14.2;
incorporate changes from 0-9-base to 0-9-ALPHA

branches: 1.13.2;
Make these files GCC 2 happy.

minor silliness related to two or more controllers

add rcsids to everything and clean up headers

support for making dev->id_alive be set, this is for iostat to
find disk devices. wee bit of a kludge. sub-device attach()
routines must now return 1 for successful attach(), 0 otherwise.
Other bsd's do this too..

fixed silly typo.

id for scsi_attach must be an int.

ioconf changes, see previous cvs's that dumped core

NDDB made a re-appearance....

new scsi subsystem.
changes also in config/mkioconf.c & sys/scsi/*

fixed to be compliant, subservient, and to take advantage of the newly
hacked config(8)

have probe return size of io space on successful return, rather
than simply 1.

dmesg output at boottime now tries to print out information as
soon as it is available. The output looks much more like Sunos.

after 0.2.2 "stable" patches applied

Make eisa_machdep build without NIOAPIC > 0 by extracting irq definition.

fix typos in word "functions" in comments, mainly s/fuctions/functions/.

fix i386 build for MSI/MSI-X support code.

branches: 1.39.6;
make pci_intr_string and eisa_intr_string take a buffer and a length
instead of relying in local static storage.

port-i386/47907: kernel trap when using EISA with I/O APIC on i386

Patch from Felix Deichmann.

XXX pullup netbsd-6

branches: 1.37.2; 1.37.8; 1.37.12;
Add bus_dma overrides. From dyoung

use c99 struct initializers

#include <sys/bus.h> instead of <machine/bus.h>.

Don't #include <sys/extent.h> any more because this module doesn't use
struct extent any more.

Delete unused functions eisa_mem_alloc() and eisa_mem_free().

struct device * -> device_t

branches: 1.31.2;
Add a 'known_mpsafe' argument to intr_establish().

Fix lossage from boolean_t -> bool and updated x86 bus_dma.

branches: 1.28.4;
__unused removal on arguments; approved by core.

- sprinkle __unused on function decls.
- fix a couple of unused bugs
- no more -Wno-unused for i386

branches: 1.26.14; 1.26.16;
Use aprint_*().

branches: 1.25.2; 1.25.4; 1.25.6;
merge ktrace-lwp.

branches: 1.24.2;
tweak x86 bus_dma code so that it can be used by xen port.

- distinguish paddr_t and bus_addr_t.
for xen, use bus_addr_t in the sense of machine address.
- move _X86_BUS_DMA_PRIVATE part of bus.h into bus_private.h.
- remove special handling of xen_shm. we can always grab
machine address from pte.

sprintf -> snprintf

* keep track of PCI buses that aren't known by firmware, but are found
by NetBSD
* use this info in in intr_find_mpmapping
* get rid of the last argument to intr_find_mpmapping, it was redundant

Add hooks and structures to allow the MP table intr mapping code a
better shot at finding a mapping. For PCI interrupts, if a bus
has no mappings, try its parent, with the swizzled pin, and the
bridge's device number.

branches: 1.19.2;
Adapt tag initialisation to the new fields that were added recently.

Adapt for i386/x86 change.

New interrupt code. The basic idea behind it is to hide the differences
in interrupt controllers in struct pic, and try to keep as much
common code as possible. At the lowest (asm) level, this is done
with CPP macros.

The main structure is now struct intrsource, describing an established
interrupt line, of any kind (soft/hard local apic/legacy apic/IO apic).
For quick masking, there may be a maximum of 32 sources per CPU.
Sources can be assigned to any CPU in the MP case, though currently they
all go to the boot CPU.

Merge Bill Sommerfeld's i386 MP branch. This code has some known
caveats, but works quite well in a lot of MP cases, and all
UP cases that I have tested. Parts of this will hopefully be
reworked in the not-too-distant future.

remove trailing \n in panic(). approved perry.

Add functions to read EISA configuration data for MEM, IRQ, DMA, and IO.

XXX Just error stubs on the i386 right now -- someone needs to write
XXX EISA BIOS code for i386.

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

EISA and PCI do not require bouncing; specify a bounce threshold of 0.

Garbage-collect the DMA tag's "_cookie" member; it's not used for anything.

Erg, typi.

Notify other machine-dependent code that the EISA bus has been configured
in the attach hook.

Pull thorpej-bus-dma branch into mainline.

branches: 1.5.8;
Implement eisa_mem_{alloc,free}(), a method for allocating/freeing
EISA bus physical address space.

This i386 implementation allocates system physical address space
after the end of RAM.

backout previous kprintf changes

printf -> kprintf, sprintf -> ksprintf

update for addition of a machine-dependent cookie as the first argument
to isa_intr_{,dis}establish().

make the EISA code look a bit more like the PCI code, in the way
the bus is configured, interrupts are handled, etc. define
eisa_chipset_tag_t and eisa_intr_handle_t types, and the following
functions:
eisa_attach_hook()
eisa_maxslots()
eisa_intr_map()
eisa_intr_string()
eisa_intr_establish()
eisa_intr_disestablish()
to do the right things for the i386.

Attach isa, eisa, and pci to mainbus now, rather than root. The i386
now has a single device tree (rather than a forest). Also, attach
EISA only if it's present, and attach in order: PCI, EISA, ISA (most
specific to least specific).
