Keyword substitution: kv
Default branch: MAIN

Driver "kqfilter" entry points return an error code, so if an invalid
filter is requested, return EINVAL rather than 1.

Change the kqueue filterops::f_isfd field to filterops::f_flags, and
define a flag FILTEROP_ISFD that has the meaning of the prior f_isfd.
Field and flag name aligned with OpenBSD.

This does not constitute a functional or ABI change, as the field location
and size, and the value placed in that field, are the same as the previous
code, but we're bumping __NetBSD_Version__ so 3rd-party module source code
can adapt, as needed.

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

- remove unused but set variables.
- use __USE() where necessary.
- remove useless 'volatile' markers

kd.c:consinit() might be wrong for old proms, but i've not
changed it really.

Welcome to 4.99.55:

- Add a lot of missing selinit() and seldestroy() calls.

- Merge selwakeup() and selnotify() calls into a single selnotify().

- Add an additional 'events' argument to selnotify() call.  It will
  indicate which event (POLL_IN, POLL_OUT, etc) happen.  If unknown,
  zero may be used.

Note: please pass appropriate value of 'events' where possible.

Extend the envsys2 API (one more time, sorry) as defined in:

http://mail-index.netbsd.org/tech-kern/2007/11/09/0001.html

sysmon_envsys_create() and sysmon_envsys_destroy() were added to
create/destroy sysmon_envsys objects (and its TAILQ/LIST for sensors/events).

sysmon_envsys_sensor_attach() and sysmon_envsys_sensor_detach() were
added to attach/detach sensors to a specified sysmon_envsys device.

The events framework is now per device and configurable via the
ENVSYS_SETDICTIONARY ioctl or /etc/envsys.conf and envstat(8).

Update all users and documentation to reflect these changes.

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.

s/cur_tre/edata/ => should fix the build error reported by rjs@.

Use PSWITCH_EVENT_{PRESSED,RELEASED} for consistency with other drivers
using the sysmon_power framework.

Imported envsys 2, a brief description of the new features:
(Part 2: drivers)

* Support for detachable sensors.
* Cleaned up the API for simplicity and efficiency.
* Ability to send capacity/critical/warning events to powerd(8).
* Adapted all the code to the new locking order.
* Compatibility with the old envsys API: the ENVSYS_GTREINFO
  and ENVSYS_GTREDATA ioctl(2)s are supported.
* Added support for a 'dictionary based communication channel' between
  sysmon_power(9) and powerd(8), that means there is no 32 bytes event
  size restriction anymore.
* Binary compatibility with old envstat(8) and powerd(8) via COMPAT_40.
* All drivers with the n^2 gtredata bug were fixed, PR kern/36226.

Tested by:

blymn: smsc(4).
bouyer: ipmi(4), mfi(4).

I expect *some* lossage here...

- use a lock to serialize tadpole_request()
- add a callback to signal monitor detection on the external VGA port
- don't call tadpole-request() in interrupt context
- use a kernel thread for various not time-critical work like device
  monitoring, LCD status updates, external event handling and so on
(the monitoring stuff is preliminary and to be replaced by a more generic API)

merge kqueue branch into -current

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

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.

* Use bus_space_map2() to map device space at a fixed virtual address.
* Remove the virtual address argument from sbus_sbus_addr()

"wierd" is weird.

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.

Pull up tctrl.c 1.12, and ts102reg.h 1.6 (both requested by toddpw):
  Prevent kernel freeze during boot on some Sparcbook 3gx's (namely, mine).
  Sparc "tctrl0" device was sensitive to undefined bits in the hardware.

Ignore all undefined bits in the Tadpole microcontroller status register.
Only the low nibble is defined, and on at least one 3gx (mine) there is an
undefined bit which reads as a one -- bit 6 (0x40). This screwed tctrl_intr()
which would loop forever, thinking it always had new events to process.

pull up sparc/sparc64 bus_intr_establish() changes, necessary for sparc64
(originally done by pk, approved by thorpej):

>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

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.

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 fallout from callout.

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.

Add port power management ioctls.

New features:
tctrl now initializes the state of the internal LCD icons.  The icons
are unprogrammed at boot time.  This incidentally makes the DC-POWER icon
work.

Fixes:
Fix my stupidity in the ENVSYS stuff, and actually follow the API.

Pull up to last week's -current.

avoid uninterruptable sleep on a CMD_REQ ioctl.

add <machine/tctrl.h> where needed.
Add some undocumented commands to the ts102 registers file, and fix a few
typos.

Modifications to tctrl.c:

Add entrypoints to driver for open/close/ioctl/poll.
Make device work with apmd. (still no support for suspend/sleep)
Make device work with ENVSYS API.
Slightly restructure handling of events.
Add function to make microcontroller requests.

Check presence of Sbus interrupt properties before using them.

This now works properly and uses interrupts.  If you close the lid, the
screen will turn off and when you open the lid screen turns on.  If you
do too rapidly, the driver won't be notified but you can press the micro
switch and it will come back.  Also "halt -p" now works so you don't
have to do Pause-P to powerdown.

Add a driver for the Tadpole SPARCbook microcontroller.  It doesn't
do much yet (except for power down support).  As sson as I figure
out to get its interrupts enabled, it will be much more functional.
(e.g., print console messages on low power warnings, be able to turn
off the TFT, etc.).
