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
Add MAINTAINER and remove the unused COMPAT_LINUX and VM_STACK defines. 1999-08-28 09:04:21 +00:00			`MAINTAINER= marcel@FreeBSD.org`

Use a consistent style and one much closer to the rest of /usr/src 2001-01-06 14:00:42 +00:00			`.PATH: ${.CURDIR}/../../compat/linux ${.CURDIR}/../../${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`
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 \`
Don't auto-generate the syscalls. 2000-12-03 01:30:31 +00:00			`linux_dummy.c linux_sysent.c linux_sysvec.c linux_util.c \`
Two sys/compat/linux sources aren't applicable on the Alpha at this time. 2000-09-06 20:21:15 +00:00			`opt_compat.h opt_linux.h opt_vmpage.h vnode_if.h`
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"`

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} \`
