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 13:32:43 -04:00
Pass maintainership over to emulation@FreeBSD.org. It has been fun, but time and other interests is making it hard. Open the door for new blood and fresh tactics now that the Linuxulator has had its facelift. Thanks to all who contributed during my tour of duty! 2001-11-18 00:45:27 -05:00			`MAINTAINER= emulation@FreeBSD.org`

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 00:30:52 -04:00			`KMOD= linux`
Round of cleanups and enhancements. These include (in random order): o Introduce private types for use in linux syscalls for two reasons: 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 syscalls and remove dummy functions or implementations of truely obsolete syscalls. o Sanitize the shm, sem and msg* syscalls. o Make a first attempt to implement the linux_sysctl syscall. At this time it only returns one MIB (KERN_VERSION), but most importantly, it tells us when we need to add additional sysctls :-) o Bump the kenel version up to 2.4.2 (this is not the same as the KERN_VERSION MIB, BTW). o Implement new syscalls, of which most are specific to i386. Our syscall table is now up to date with Linux 2.4.2. Some highlights: - Implement the 32-bit uid_t and gid_t bases syscalls. - Implement a couple of 64-bit file size/offset bases syscalls. o Fix or improve numerous syscalls and prototypes. o Reduce style(9) violations while I'm here. Especially indentation inconsistencies within the same file are addressed. Re-indenting did not obfuscate actual changes to the extend that it could not be combined. NOTE: I spend some time testing these changes and found that if there were regressions, they were not caused by these changes AFAICT. It was observed that installing a RH 7.1 runtime environment did make matters worse. Hangs and/or reboots have been observed with and without these changes, so when it failed to make life better in cases it doesn't look like it made it worse. 2001-09-08 15:07:04 -04:00			`SRCS= linux_dummy.c linux_file.c linux_getcwd.c linux_ioctl.c linux_ipc.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 15:00:35 -05:00			`OBJS= linux_locore.o`

It is unlikely that we'll be supporting old-style ZMAGIC linux a.out binaries on anything but i386.. (ia64, sparc64, etc) Invert the .if so that it is inclusive of i386 platforms rather than excluding just the alpha. 2001-01-06 22:10:15 -05:00			`.if ${MACHINE_ARCH} == "i386"`
opt_kstack_pages.h is not needed anymore. It would have been a Bad Thing if it had been different to the running kernel. 2002-09-07 22:59:38 -04:00			`SRCS+= linux_ptrace.c linux_uid16.c imgact_linux.c opt_cpu.h`
Two sys/compat/linux sources aren't applicable on the Alpha at this time. 2000-09-06 16:21:15 -04:00			`.endif`

(Belatedly) add the required EXPORT_SYMS. I'm not sure the list is complete, but at least linprocfs works (I haven't had the opportunity to test other stuff that depends on the linux module, like aac or tdfx) 2002-02-22 13:21:20 -05:00			`EXPORT_SYMS=`

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.
