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
Connect the new sources in /sys/compat/linux and the new file in /sys/i386/linux. 2000-08-22 06:02:01 +00:00			`.PATH: ${.CURDIR}/../../compat/linux ${.CURDIR}/../../${MACHINE_ARCH}/linux`
Add MAINTAINER and remove the unused COMPAT_LINUX and VM_STACK defines. 1999-08-28 09:04:21 +00:00

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`
Support for the linux ipc syscalls on the alpha, where each one has its own syscall rather than going through a demux function like linux_ipc() on i386 2000-11-01 23:17:31 +00:00			`SRCS= linux_file.c linux_ioctl.c linux_ipc.c linux_machdep.c linux_misc.c \`
Two sys/compat/linux sources aren't applicable on the Alpha at this time. 2000-09-06 20:21:15 +00:00			`linux_signal.c linux_socket.c linux_stats.c linux_mib.c \`

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			`OBJS= linux_locore.o`

Since AlphaLinux is the weirdest Linux of all, probably best to do the logic this way. 2000-09-06 20:21:55 +00:00			`.if ${MACHINE_ARCH} != "alpha"`

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`
Use genassym(1) and <sys/assym.h> to generate assembler symbols. 1999-12-23 19:59:47 +00:00			`CLEANFILES= linux_assym.h linux_genassym.o`
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

Use the genassym script here too. The linux and svr4 modules were broken. 2000-06-03 07:40:19 +00:00			`.if exists(@)`

			`linux_locore.o: linux_locore.s linux_assym.h`
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 $@ ...", so that genassym(1) doesn't need to support -o. Removed duplicate -D_KERNEL from flags for compiling linux_locore.s. 2000-01-09 10:04:53 +00:00			`${CC} -c -x assembler-with-cpp -DLOCORE ${CFLAGS} \`
Fixed the `machine' link. It pointed to the wrong place, and was created too late to be used in all cases. It should probably be created (early) in bsd.kmod.mk for all LKMs. Use cc instead of cpp \| as for the same reasons as in the kernel makefile. CFLAGS isn't split up as well as in the kernel makefile, but cc doesn't pass compiler warning flags to cpp, so there is no need to split it. 1996-06-25 20:13:12 +00:00			`${.IMPSRC} -o ${.TARGET}`
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
Fixed a race to build the `@' and `machine' symlinks early enough for `make -jN'. 1998-03-19 12:35:55 +00:00			`linux_genassym.o: linux_genassym.c linux.h @ machine`
