calling the C functions mtx_enter_hard() and mtx_exit_hard() clobbers them.
Note that %eax is also not call safe, but it is already clobbered due to
cmpxchg. However, now we are back to not compiling again, so these macros
are still left disabled for now.
slightly more sane. Make the arguments to the nop MPASS2 match those
of the functional one. Change 4 spaces to a tab. Don't indeent a
label so its easier to see.
infrastructure. It's not perfect, but it's a lot better than what
we've been using so far. The following rules apply to this:
o BSD component names should be capitalised
o Layer names should be taken from the non-CA set for now. We
may elect to add some new BSD-specific layers later.
- Make it possible to turn off selective debugging flags or layers
by listing them in debug.acpi.layer or debug.acpi.level prefixed
with !.
- Fully implement support for avoiding nodes in the ACPI namespace.
Nodes may be listed in the debug.acpi.avoid environment variable;
these nodes and all their children will be ignored (although still
scanned over) by ACPI functions which scan the namespace. Multiple
nodes can be specified, separated by whitespace.
- Implement support for selectively disabling ACPI subsystem components
via the debug.acpi.disable environment variable. The following
components can be disabled:
o bus creation/scanning of the ACPI 'bus'
o children attachment of children to the ACPI 'bus'
o button the acpi_button control-method button driver
o ec the acpi_ec embedded-controller driver
o isa acpi replacement of PnP BIOS for ISA device discovery
o lid the control-method lid switch driver
o pci pci root-bus discovery
o processor CPU power/speed management
o thermal system temperature detection and control
o timer ACPI timecounter
Multiple components may be disabled by specifying their name(s)
separated by whitespace.
- Add support for ioctl registration. ACPI subsystem components may
register ioctl handlers with the /dev/acpi generic ioctl handler,
allowing us to avoid the need for a multitude of /dev/acpi* control
devices, etc.
that of MTX_EXIT. Don't assume that the reg parameter to MTX_ENTER
holds curproc, load it explicitly. Put semi-colons at the end of
the macros to be more consistent and so its harder to forget them
when these change.
member f_devdata to be a pointer to a socket number. When currdev
is "pxe", that assumption is correct. When currdev is "disk*", that
assumption is incorrect.

We must force payload alignment to a longword boundary to make the
alpha happy. This should stop the driver from trapping on the alpha
when the interface is ifconfig'ed (actually, when the first frame is
received).

- Read the database from /usr/share/misc (or wherever else we're pointed)

USB WebCams, using a patch from Peter Housel.
With this change ugen, and with Peter's 'vid' program
in ports/graphics/vid, we can capture single images from USB Cameras
using the OmniVision OV511 chipset (including some models of the
Creative WebCam 3)
NetBSD merged in Peter's patch to their ugen.c file
several months ago, so this brings us back in line.

Change a few indentations to tabs.
Change the functions to use ANSI sytle parameters.
This lowers the diffs between our copy of ugen.c and NetBSD's copy
