9edac6f3f9 add KTRACE hooks into kevent... This will help people debug their kqueue
programs to find out exactly which events were registered and which were
returned...  This should be lower in kern_kevent, but that would require
special munging due to locks and the functions used to copyin/copyout
kevents...

If someone wants to teach ktrace how to output pretty kevents, I have a
kevent prety printer that can be used...

b611c801f0 MFp4 the sound Google Summer of Code project:
The goal was to sync with the OSSv4 API 4Front Technologies uses in their
proprietary OSS driver. This was successful as far as possible. The part
of the API which is stable is implemented, for the rest there are some
stubs already.

New system ioctls:
 - SNDCTL_SYSINFO - obtain audio system info (version, # of audio/midi/
   mixer devices, etc.)
 - SNDCTL_AUDIOINFO - fetch details about a specific audio device
 - SNDCTL_MIXERINFO - fetch details about a specific mixer device

New audio ioctls:
 - Sync groups (SNDCTL_DSP_SYNCGROUP/SNDCTL_DSP_SYNCSTART) which allow
   triggered playback/recording on multiple devices (even across processes
   simultaneously).
 - Peak meters (SNDCTL_DSP_GETIPEAKS/SNDCTL_DSP_GETOPEAKS) - can query
   audio drivers for peak levels (needs driver support, disabled for now).
 - Per channel playback/recording levels -
   SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL.  Note that these are still in name
   only, just wrapping around the AC97-style mixer at the moment. The next
   step is to push them down to the drivers.

Audio ioctls still under development by 4Front (for which stubs may exist
in this commit):
 - SNDCTL_GETNAME, SNDCTL_{GET,SET}{SONG,LABEL}
 - SNDCTL_DSP_{GET,SET}_CHNORDER
 - SNDCTL_MIX_ENUMINFO, SNDCTL_MIX_EXTINFO - (might be documented enough in
   the OSS releases to work on this.  These ioctls cover the cool "twiddle
   any knob on your card" features.)

Missing:
 - SNDCTL_DSP_COOKEDMODE -- this ioctl is used to give applications direct
   access to a card's buffers, bypassing the feeder architecture.  It's
   a toughy -- "someone" needs to decide :
   (a) if this is desireable, and (b) if it's reasonably feasible.

Updates for driver writers:
 So far, only two routines to the channel class (in channel_if.m) are added.
 One is for fetching a list of discrete supported playback/recording rates
 of a channel, and the other is for fetching peak level info (useful for
 drawing peak meters).  Interested parties may want to help pushing down
 SNDCTL_DSP_{GET,SET}{PLAY,REC}VOL into the drivers.

To use the new stuff you need to rebuild the sound drivers or your kernel
(depending on if you use modules or not) and to install soundcard.h (a
buildworld/installworld handles this).

153c21c8c1 If /dev/tty gets opened after your controlling terminal has been revoked
you can't call tty_clone afterwords. OpenBSD and NetBSD both fail the
open call in that case, so we should do so as well. This can
be done in ctty_clone by returning with *dev==NULL. Admittedly this
causes open to return ENOENT, instead of ENXIO as on the other BSDs,
but this way requires the least touching of code.

07a8ebcc75 Stop reloading %fs and %gs, since it causes the base address from
GDT to be loaded into FS.base and GS.base, these values of course
are not the values set by sysarch() with I386_SET_FSBASE and
I386_SET_GSBASE, the change fixed a crash for 32bit libthr after
signal handler returned and normal code is accessing thread pointer,

d72a078647 Update the ipmi(4) driver:
- Split out the communication protocols into their own files and use
  a couple of function pointers in the softc that the commuication
  protocols setup in their own attach routine.
- Add support for the SSIF interface (talking to IPMI over SMBus).
- Add an ACPI attachment.
- Add a PCI attachment that attaches to devices with the IPMI interface
  subclass.
- Split the ISA attachment out into its own file: ipmi_isa.c.
- Change the code to probe the SMBIOS table for an IPMI entry to just use
  pmap_mapbios() to map the table in rather than trying to setup a fake
  resource on an isa device and then activating the resource to map in the
  table.
- Make bus attachments leaner by adding attach functions for each
  communication interface (ipmi_kcs_attach(), ipmi_smic_attach(), etc.)
  that setup per-interface data.
- Formalize the model used by the driver to handle requests by adding an
  explicit struct ipmi_request object that holds the state of a given
  request and reply for the entire lifetime of the request.  By bundling
  the request into an object, it is easier to add retry logic to the various
  communication backends (as well as eventually support BT mode which uses
  a slightly different message format than KCS, SMIC, and SSIF).
- Add a per-softc lock and remove D_NEEDGIANT as the driver is now MPSAFE.
- Add 32-bit compatibility ioctl shims so you can use a 32-bit ipmitool
  on FreeBSD/amd64.
- Add ipmi(4) to i386 and amd64 NOTES.

b8a4b36974 The sparc64/sparc64/pmap.c implementations of pmap_remove(),
pmap_protect(), and pmap_copy() have optimizations for regions
larger than PMAP_TSB_THRESH (which works out to 16MB).  This
caused a panic in tsb_foreach for kernel mappings, since
pm->pm_tsb is NULL in that case.  This fix teaches tsb_foreach
to use the kernel's tsb in that case.

4542a3798e Connect up a QUEUE FULL event with CAM and adjust openings.
Unfortunately, the QUEUE FULL event only tells you Bus && Target.
It doesn't tell you lun. In order for the XPT_REL_SIMQ action to
work, we have to have a real lun. But which one? For now, just
iterate over MPT_MAX_LUNS.

Practically speaking, this is only going to be happening for lower
quality SAS or SATA drives behind the SAS controller, which means
only lun 0, so it's not so bad.
