1. establish type independence for ease in porting and,
2. provide a visual queue as to which syscalls have proper
prototypes to further cleanup the i386/alpha split.
Linuxulator types are prefixed by 'l_'. void and char have not
been "virtualized".
o Provide dummy functions for all unimplemented syscalls, except for
the osf1 syscalls. This can only be done if the osfulator
implements at least all syscalls used by the linuxulator. Remove
dummy functions for syscalls that are now truely unimplemented.
o Set the syscall namespace as follows: Mark a syscall as OSF1 if
the Linux kernel has prefixed the syscall with 'osf_' and has
provided special implementations for it. Otherwise mark the
syscall as LINUX by default. Some of the LINUX syscalls remain
marked as BSD or POSIX.
o Rename syscalls so they match the names used in the Linux kernel.
Also, provide more accurate prototypes. This generally improves
cross-referencing and reduces head-scratching.
o Fix the (g|s)etresuid syscalls. They mapped to (g|s)etresgid.
o Sanitize the the shm*, sem* and msg* syscalls. Their prototypes
were dictated by the way these syscalls were used in the i386
code. That has been fixed. NOTE: linux_semctl now passes it's
'arg' parameter by value and not by reference.
o Fix prototype of linux_utime. It takes a struct timeval, not a
struct utimbuf.
o Fix the linux_sysfs syscall. It's index is not 255, but 254.
o Implement the following syscalls:
linux_sysctl
o Add the following new syscalls:
(g|s)etresgid
linux_pivot_root (dummy)
linux_mincore (dummy)
linux_pciconfig_iobase (dummy)
linux_getdents64

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ 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, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. 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, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
