Keyword substitution: kv
Default branch: MAIN

Re-factor the boot device and consinit routines into common functions
per platform type (PCI vs TC), eliminating a bunch of copy-pasta.

In dec_6600_device_register(): If we're running on a DS10, set the
"pciide-disable-dma" property on the on-board "aceride" to true.  This
is intended to be a temporary measure until the issue that makes it not
work correctly is found and fixed.

Always call platform.device_register(), even if bootdev_data is NULL.

Convert the Alpha port's bus_space back-end to manage address space
with vmem(9) arenas (using statically-allocated private boundary tags
for very early-in-boot) rather than extent(9).

As a side-effect, there's arguments to some initialization functions
that are no longer required, so garbage-collect those, update all the
call sites.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.

Pull up revision 1.21 (requested by mycroft in ticket #607):
  Significantly cleanup and bug fix root device detection:
   o On systems where it is relevant (6600, kin300, kn8ae),
     check which PCI bus hierarchy we are looking at.
   o Consistently check PCI function numbers (important for
     quad-channel ATA controllers).
   o Check logical unit numbers.
   o Use strcasecmp() to check b->protocol; the case is
     different depending on firmware revision.
   o Remove b->boot_dec_type check, it is unneeded.
   o Remove extraneous unneeded variables.
  Fixes PR#9432, PR#12225, PR#25830 and multiple long-standing
  bugs, and the code is smaller too.

Significant cleanup and bug fix of root device detection:

No need to include wdvar.h anymore.

Catch up to ata/ide changes; look for a parent device of wd named "atabus"
instead of "pciide", and check one layer farther up in the device hierarchy
for the scsipidev device.

From Manuel Bouyer, tested by me on a up1500 (identical changes to other
ide-booting code).

Also pass a type argument to comcnattach() and com_kgdb_attach().
comspeed() (and thus cominit()) may need this information.

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

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

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.

Get the pointer to the driver name early, rather than always dereferencing
the cfdriver pointer.

Catch up to -current.

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.

Get rid of port-dependent conf.h.

add missing   #include "opt_kgdb.h"

Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
  ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
  to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
  peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
  recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
  scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
  (no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
  set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
  the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
  will be requeued, or a REQUEST SENSE will be sent as appropriate.

Add support for attaching "com" serial ports as KGDB devices.

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.

Update from trunk:
Implement bus_get_window on Tsunami and MCPCIA, and compensate for
the Cool sign-extend hack we use on EV6 when mapping PCI space into
userspace.

Implement tsp_bus_get_window().

CDROMs can exist on ide buses

increase number of parameters of pckbc_cnattach(), since offset of command port
is not 4 (KBCMDP), but 1 on jazz based platforms of arc port.

Needs to look at different stuff depending if the scsipi bus is SCSI or ATAPI

When checking for netboot, also check for MOP protocol.

Pull up revision 1.3 (requested by veego):
  Fix detection of booted device for IDE drives, such that automatic
  booting from a slave drive or a drive on the second channel works.

Sync the ide support with dec_eb164.c rev 1.32:
Add the support to boot an ide slave drive and to boot from the secondary
ide channel.
Michael Hitch gave me the final hint how to do that and Havard Eidnes
tested it with his slave drive.
This should fix pr#8808 on the DS10.
Also remove one ideboot check which wasn't removed when I removed it from
dec_eb164.c.

Pull up to last week's -current.

Split the PC-like keyboard controller driver into chip back-end and
bus front-end.
