Keyword substitution: kv
Default branch: MAIN

remove TTY_DEBUG code from sun2/sparc64 zs.c code. it doesn't look relevant
to this particular drivers and likely is a leftover from some historical code.

sparc64/zs(4): Convert to ttylock/ttyunlock.

ddb/db_active.h: New home for extern db_active.

This can be included unconditionally, and db_active can then be
queried unconditionally; if DDB is not in the kernel, then db_active
is a constant zero.  Reduces need for #include opt_ddb.h, #ifdef DDB.

Add missing double p and d for stopped and overriden accordingly.
Fix few more typos along the way, mainly in copy-pasted comments.

Merge thorpej-cfargs2.

Adapt to CFARGS().

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?).

Give config_found() the same variadic arguments treatment as
config_search().  This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls.  Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.

Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

Compare driver name, don't check against zstty_cd.

Use /options instead of /chosen to find out where console is.
(found by Rafal Boni).

Protect extern zstty_cd with (NKBD > 0) || (NMS > 0)

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

catch up with -current on kqueue branch

Remove hard-coded major.

Catch up to -current.
(CVS: It's not just a program. It's an adventure!)

Add missing semicolon.

Overhaul bus space.

bus_space_handle_t now holds an address and two ASIs, one for normal accesses
and one for streaming accesses.  This allows to map individual handles
different ways, so some can use MMU bypass accesses and others use virtual
addresses.  bus_space_map() will now create handles that use bypass accesses
unles BUS_SPACE_MAP_LINEAR is passed in.  So only pass in BUS_SPACE_MAP_LINEAR
if you absolutely *need* to use bus_space_vaddr().  This removes at least one
extra level of indirection and should reduce TLB misses.

32-bit kernels have problems accessing 64-bit addresses, so they always use
virtual addresses.

sbus_bus_map() no longer has a preferred vaddr parameter.

Sync kqueue branch with -current.

Catch up with -current. Fix some bogons in the sparc64 kbd/ms

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.

remove unused variable

Attach the sunkbd line discipline to zstty.

pullup the contents of -current arch/sparc64.  this gives us significant
ultrasparc PCI support (ultra5, ultra10, AXi, and E250 tested so far),
plus many other small fixes.  netbooting is now supported.

Function signature for bus_intr_establish() changed.

Upgrate interrupt handling:

	1) use interrupt vectors for specific zs chips rather than polling
	   all of them.

	2) use softintr_schedule() and schedule it for a particular device
	   rather than poll all devices.

Add a `device class' interrupt level argument (from machine/intr.h)
to bus_interrupt_establish().

It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt
level to devices in PCI slots.

Get rid of vaddrs.h.

Sync w/ netbsd-1-5-base.

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

Fix the sparc64 console.

Unlike the other Sun machines, UltraSPARCs can have consoles run on different
chips than zs, so we need to support them.  So, here we go:

	Add a new PROM console driver with a major number and everything.
	This is the default driver if nothing else attaches.  It does not
	use the keyboard driver since the PROM translates keystrokes itself.
	(Unfortunately it also swallows L1-A).

	Have the keyboard driver take over the console when it attaches on a
	serial port.  When a serial port detects a keyboard and attaches the
	keyboard driver, it needs to provide a set of consdev vectors.  They
	keyboard driver will use those to send I/O to the keyboard and mouse.

move zs_attach() to after the setting of the console device, to avoid
having cn_dev being 0 and thus cnopen() being called recursively.  this
fixes this problem for zs-based console's only.

this does not need auxreg.h

Get a kernel without DDB to build.

include <ddb/db_output.h> to get the db_printf() prototype.

Revamp interrupts again:

	Fix a bug causing interrmittent panics in interrupt dispatch.
	Use interrupt vectors for softints.
	Add a new send_softint interface.
	Improved D$ flushing.
	Improve traptrace and other debugging enhancements.

- Implement cnbell() -- ring the console bell.  The cn_bell entrypoint
  is optional.
- Add cn_bell to statically allocated consdevs as appropriate.

Pull up to last week's -current.

Update to post 1.4.

Sync w/ -current.

Start putting in hooks for non-zs console devices.

Defer final console attach to zs_attach().

Deprecate `findzs()' and try to map in the zs registers if they're not mapped
by the prom.

Add pps support. Only enable pps if CLOCAL & !MDMBUF.

Let's try to make prom_cnget() work.

Minor cleanup.
Make the initializer for BAUDLO depend on PCLK directly; it was incorrect on
some ports where PCLK is not 4.9152MHz.
XXX Is the default value actually used?

Don't set DCD_IE in the frontends.  KGDB doesn't even use DCD, and the tty
frontends get it from zsparam() anyway.

It slices.  It dices.  It does everything except exec a sparc32_compat init.

Periodic update: now starts probing devices.

Merge paddr_t changes into the main branch.

Split vm_offset_t and vm_size_t into paddr_t, psize_t, vaddr_t, and vsize_t.

defopt DDB.

Import of sparc64.
