First incarnation of our Linux emulator or rather compatibility code. This first shot only incorporaties so much functionality that DOOM can run (the X version), signal handling is VERY weak, so is many other things. But it meets my milestone number one (you guessed it - running DOOM). Uses /compat/linux as prefix for loading shared libs, so it won't conflict with our own libs. Kernel must be compiled with "options COMPAT_LINUX" for this to work. 1995-06-25 17:32:43 +00:00
Replace 'i386' with '${MACHINE_ARCH}' in preparation of the development of a linuxulator for Alpha. 1999-11-12 20:04:59 +00:00			`.PATH: ${.CURDIR}/../../${MACHINE_ARCH}/linux`

Sample initial set of kld-ified modules. Not all have been completely converted yet. These are more of a starting point. This is NOT connected to the parent Makefile. OK'ed by jkh (who is ever so patiently waiting) 1998-10-16 04:30:52 +00:00			`KMOD= linux`

Add sysctl variables for the Linuxulator. These reside under `compat.linux' as discussed on current. The following variables are defined (for now): osname (defaults to "Linux") Allow users to change the name of the OS as returned by uname(2), specially added for all those Linux Netscape users and statistics maniacs :-) We now have what we all wanted! osrelease (defaults to "2.2.5") Allow users to change the version of the OS as returned by uname(2). Since -current supports glibc2.1 now, change the default to 2.2.5 (was 2.0.36). oss_version (defaults to 198144 [0x030600]) This one will be used by the OSS_GETVERSION ioctl (PR 12917) which I can commit now that we have the MIB. The default version number is the lowest version possible with the current 'encoding'. A note about imprisoned processes (see jail(2)): These variables are copy-on-write (as suggested by phk). This means that imprisoned processes will use the system wide value unless it is written/set by the process. From that moment on, a copy local to the prison will be used. A note about the implementation: I choose to add a single pointer to struct prison, because I didn't like the idea of changing struct prison every time I come up with a new variable. As a side effect, the extra storage is only needed when a variable is set from within the prison. This also minimizes kernel bloat when the Linuxulator is not used; both compiled in or as a module.

Update the linux lkm to use the new file list and build routine. This is a bit of a kludge and needs more work. 1996-03-02 20:00:35 +00:00			`linux_dummy.c linux_sysent.c linux_sysvec.c linux_util.c \`

First attempt at FreeBSD & Linux ELF support. Compile and link a new kernel, that will give native ELF support, and provide the hooks for other ELF interpreters as well. To make native ELF binaries use John Polstras elf-kit-1.0.1.. For the time being also use his ld-elf.so.1 and put it in /usr/libexec. The Linux emulator has been enhanced to also run ELF binaries, it is however in its very first incarnation. Just get some Linux ELF libs (Slackware-3.0) and put them in the prober place (/compat/linux/...). I've ben able to run all the Slackware-3.0 binaries I've tried so far. (No it won't run quake yet :) 1996-03-10 08:42:54 +00:00			`EXPORT_SYMS=_linux_mod`

Compile linux_genassym.c with ordinary ${CFLAGS}. The (small) need for -U_KERNEL became negative when all all the genassym.c's were converted to be cross-built. Use "genassym ... > ${.TARGET}", not "genassym -o $@ ...", so that genassym(1) doesn't need to support -o. Removed duplicate -D_KERNEL from flags for compiling linux_locore.s. 2000-01-09 10:04:53 +00:00			`genassym ${.ALLSRC} > ${.TARGET}`

Fixed the `machine' link. It pointed to the wrong place, and was created too late to be used in all cases. It should probably be created (early) in bsd.kmod.mk for all LKMs. Use cc instead of cpp \| as for the same reasons as in the kernel makefile. CFLAGS isn't split up as well as in the kernel makefile, but cc doesn't pass compiler warning flags to cpp, so there is no need to split it. 1996-06-25 20:13:12 +00:00			`${.IMPSRC} -o ${.TARGET}`
