thorpej | Several years ago, the interrupt priority levels for devices were "flattened"
such that IPL_BIO, IPL_NET, and IPL_TTY (logical interrupt priority levels)
became aliases of IPL_VM (the logical interrupt priority level above which
memory allocation is not allowed). Unfortuantely, this meant that any
use of these logical interrupt priority levels to differentiate between
different interrupt service routines at the same auto-vectored interrupt
level was pointless... "when everyone is special, no one is".
Before this flattening happened, these distinct logical interrupt priority
levels levels were dynamically mapped to physical auto-vectored interrupt
levels based on which types of devices registered themselves at which auto-
vectored level. Now, splbio(), splnet(), etc. are all equivalent to splvm(),
which effectively blocks all device interrupts.
Switch to using the ISRPRI_* values provided by the common m68k interrupt
dispatch code, which allows interrupt handlers for devices that are more
latency-sensitive to be sorted earlier in the list of handlers at a given
auto-vectored interrupt level, as was originally intended.

thorpej | branches: 1.42.8;
Merge thorpej-cfargs branch:
Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.
Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)
Remove unnecessary or redundant interface attributes where they're not
needed.
There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)
...and a sentinel value CFARG_EOL.
Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.
Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

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.

gmcgarry | branches: 1.27.2;
Clean-up the DIO bus. Includes two main changes:
1) Pass address and ipl locators at attachment;
2) Remove hack which made the internal HP-IB controller
look like a DIO device.
The hack to allow the nhpib driver to support internal and DIO
controllers appears to be a leftover from 4.3BD where it was not
possible to have a driver attach to different busses. NetBSD has
supported bus-dependent attachments for a long time.

Fix typo: calllout_reset -> callout_reset.
|
| 1.22 |
| 23-Mar-2000 |
thorpej | New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.

thorpej | Back most (not all) of the previous delay-related changes now that
delay is calibrated properly.
|
| 1.10 |
| 17-May-1996 |
thorpej | Change "DELAY(1)" to "DELAY(5)". This is basically equivalent to how
the old implementation of DELAY() behaved with small values.
|
| 1.9 |
| 14-Feb-1996 |
thorpej | All interrupt routines (except the HIL; don't ask) now take a pointer
to a softc, rather than a unit number. Add a "dq_softc" member
to struct devqueue; this is a temporary measure until the
dma/controller/device callback spaghetti is untangled.
YAY! No more need for dcafastservice!
HIL: squish instances of "(void) splhil()" and "(void) spl0();".
|
| 1.8 |
| 02-Dec-1995 |
thorpej | Use a "match/attach" rather than "init" scheme for probing devices.
This is a step towards getting the drivers ready for new config.
|
| 1.7 |
| 19-Nov-1995 |
thorpej | Do an indirect driver a little more like an indirect driver would like to
be done. Set up a structure filled with function pointers in the
controller-specific probe routines, and jump through them, instead of
if()'ing our way though each operation.
Be a little more discriptive; print out the controller type found
during the probe in a way that's somewhat meaningful.

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.
