This port is an emulation layer to port linux device drivers to FreeBSD,
mostly oriented to USB device drivers where FreeBSD support is weaker.
It contains:
- a set of headers with declarations for entities used in the Linux kernel;
- a compatibility library (in source form) mapping [part of] the linux kernel
APIs to equivalent FreeBSD APIs;
- a template for character device drivers.
Ideally, the porting of a linux driver should be as simple as downloading
the linux driver sources, writing a simple Makefile.kmod, and running
"make -f Makefile.kld" to produce your driver.ko.

Make this port build under FreeBSD 7, enabling dependent
drivers (e.g. linux-gspca-compat and others) to build too.
The fixes in the code are really minor (basically workaround a
change in the definition of msleep).
Upgrade to version 20070326, which implements device control variables
(available under /proc on Linux) as a sysctl tree debug.{drivername}
With this feature you can, as an example, set
sysctl debug.gspca.compress=1 and sysctl debug.gspca.autoexpo=0
to speed up capture on some cameras.
This version also includes some pwcview changes to display up
to 4 copies of the grabbed image, with various mirroring options.
Update to the 20070208 release of the code.
Apart from internal cleanup, a visible change is that
mmap-related ioctl in video drivers are trapped and made
to return EINVAL.
This prevents clients (e.g. ekiga) that do not check for mmap() errors
from crashing.
I suggest to rebuild linux-gspca-kmod and linux-ov511-kmod.
update to version 20070203, which enables build of children
ports (linux-gspca-kmod, linux-ov511-kmod) on 64 bit archs.
Thanks to Jung-uk Kim for the 64-bit patches.
- Add automatic pkg-plist generation
- Remove NO_PACKAGE (for the above reason)
- Add NO_BUILD
- Various fixes (also for portlint)
This commit doesn't change which files are installed and where
(the port is still not PREFIX clean).
Add new port for linux-kmod-compat - emulation layer to build
linux device drivers as FreeBSD kld modules. Details at
http://info.iet.unipi.it/~luigi/FreeBSD/linux_bsd_kld.html
Two ports for webcam drivers that use this package are coming in
a matter of minutes.
NOTES:
+ This is only for 6.x and 7.x, no support planned for earlier versions.
+ At the moment only i386 but have patches for 64-bit architectures
that should be committed soon.
+ This port installs a file in /usr/share/mk . After some discussion
on the ports list this seems, to be the most reasonable thing to do.
portlint complains about it.
