removed quite many years ago. Drop the _emul component of config machinery
symbol names, and merge the wsdisplay_emul_smth with wsdisplay_common_smth
as they are their only users.
No functional change, but you need to rerun config(8) on your kernels.

Without this, the kernel could be made to access random memory after receiving
some specially crafted DCS or CSI terminal escape sequences.

When finishing a wseventvar in wsevent_fini(), clear the klist.
Otherwise knotes can be left dangling, which can crash the kernel.
In general, klist_invalidate() should happen after vdevgone() in order
to avoid a race with kevent registration. However, the current wscons
drivers clear the wsevent pointer (sc->sc_base.me_evp) before calling
wsevent_fini(). This prevents the drivers from registering new kevents.

The CONFIGURED flag, which indicates that first-time initialization

This happens on the new 14" and 16" Macbook Pro where we deliberately use
a framebuffer that skips the first few lines to avoid "the notch".
The offset of the first pixel is added to struct wsdisplay_fbinfo. The
stride is added as well, mirroring the value returned by the
WSDISPLAYIO_LINEBYTES ioctl, such that we can retire that one in the
future. A compat ioctl is implemented to help the transition. The compat
code will be removed after OpenBSD 7.3 has been released.

contrast) are not valid if they only have one state, i.e. minimum and maximum
values being equal.
Do not expose them to userland in this case, for wsconsctl would attempt to
divide by zero (which is known to have unwelcome consequences).
This allows display drivers trusting not-so-reliable sources (fdt, bogus
hardware...) to not have to perform those checks themselves.
Found the hard way by daniel@. No firm consensus on this workaround, using
one seniority point here, will revert if this spawns complaints.

This change fixes bugs concerning the transition into the hold/drag state
after double taps or two- or three-finger taps. In addition, it ensures
that button events properly match the logical button state when tap inputs
and button inputs overlap.

attached audio device, i.e. audio0. This approach does not work well
while using additional audio devices equipped with physical volume keys
since those would only affect the volume of audio0.
Instead, correlate audio and ucc devices attached over USB in order to
adjust the volume of the correct audio device. This is done by passing a
cookie from the common point of attachment which is later used to
correlate the audio and wskbd device.
The same approach could be adopted for audio and wskbd devices attaching
on a different bus. Keep in mind that it's of importance to make use of
and increment the same global cookie identifier to avoid collisions.
Makes the volume keys on my Logitech G435 Headset do the right thing.

keyboard attached and /etc/kbdtype being present. The advertised
encoding of a wsmux is a bit fragile as the last attached device will
dictate it. If this happens to be a ucc keyboard, KB_US will always be
the advertised encoding as its encoding is immutable and /etc/kbdtype is
ignored.
Instead, do not advertise the encoding for ucc devices when the parent
mux queries its attached devices. However, asking the device directly
(i.e. bypassing the mux) still returns the encoding as wsconsctl(8)
would otherwise report an error.
Thanks to landry@ for the report and testing.
