remove the former. All other EGA/VGA methods were already shared, with VGA-only features mostly not used and no decisions in inner loops to optimize fof VGA, but this method was split up because it is the only important one and using VGA methods if possible is about twice as fast. The speed is mostly not from splitting to reduce branches but from doing half as many bus accesses, so make this easier to maintain by not splitting. There is now 1 extra branch in an inner loop where it costs less than 1% of the bus access overhead on Haswell even if the compiler schedules it poorly.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
