Bring back the `config file in the kernel' feature from the 1.x days. This is conditionalized by the INCLUDE_CONFIG_FILE option in your kernel config file and is not turned on by default. Submitted-By: Bill Pechter <pechter@shell.monmouth.com>

# from: @(#)Makefile.i386 7.1 5/10/91
Delete the 'device-driver' suffix. It's been meaningless for a long time. On the VAX, it used to be used for special compilation to avoid the optimizer which would mess with memory mapped devices etc. These days we use 'volatile'.

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

Put in an initial %VERSREQ field. This will cause existing config(8)'s to give a non-fatal warning about unknown directives, so there is no hurry to rebuild config(8) yet, apart from shutting up the warning.
1997-10-22 00:48:36 +00:00
# Which version of config(8) is required.
Move a couple of bits of (now) static content from config(8) (ie: %LOAD) directly into the Makefile. Remove references to swapkernel.c, it's not generated by config(8) now. (The previous config commits had generated it, but they had an unused 'char *' in them).

Move KERNEL?=kernel to top of the file where it's more obvious and add a pointer to 'makeoptions' and /etc/make.conf. Catch a few stray "kernel" hardcoded references. Move the kernel.debug and related kernel build rules together.
1999-05-09 22:42:17 +00:00
# Can be overridden by makeoptions or /etc/make.conf
KERNEL?= kernel
Flip the kernel default to ELF.. Add a test to try and warn people that they might be about to blow their feet off if they have not been reading their mail. I don't know if or how well this will work, but it's worth a try.
1999-01-07 06:52:41 +00:00

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

COPTFLAGS?=-O
Added -I- to ${INCLUDES}. This makes 4.4Lite's (mis?)use of "foo.h" for headers in the compile directory work unsurprisingly. Without -I-, the search for "foo.h" begins in the directory of the file that includes it, and the compile directory is only searched because `-I.' is in ${INCLUDES}. Removed -I$S/sys from ${INCLUDES}. It was once necessary to find things like "param.h" in $S/sys. Now <sys/param.h> is found in $S.

Fixed missing dependencies of genassym.o, gensetdefs.o and vers.o on opt_global.h. This actually matters for genassym.o (it depends on at least SMP). Don't undefine KERNEL for compiling genassym.c. genassym.o really depends on KERNEL, and the prototype mismatches that required undefining KERNEL in rev.1.49 no longer exist. Compile gensetdefs* with the same flags as genassym*. External `gen' programs such linux_genassym should also use these flags (${GEN_CFLAGS}). Fixed missing dependency generation for gensetdefs.o. C sources for external `gen' programs should be added to GEN_CFILES to get their dependencies generated. Cleaned up flags definitions and use. All of ${CFLAGS} is now passed to mkdep and the assembler (both are actually variants of ${CC} and will ignore the irrelevant flags).

Increased kernel virtual address space to 1GB. NOTE: You MUST have fixed bootblocks in order to boot the kernel after this! Also note that this change breaks BSDI BSD/OS compatibility. Also increased default NKPT to 17 so that FreeBSD can boot on machines with >=2GB of RAM. Booting on machines with exactly 4GB requires other patches, not included.

LOAD_ADDRESS?= C0100000
Fixed the fix for not using -fomit-frame-pointer with -pg. The previous fix stopped it being used in all cases, because substitution on unset variables does not work. When profiling, put -malign-functions=4 in CFLAGS instead of in PROF. This fixes the histogram counts for profiling support functions. It gives bogus but harmless extra alignment for genassym etc.

DEFINED_PROF= ${PROF}
Moved nonstandard compiler profiling options out of config. Just print the profiling level in config and decide what to do in makefiles. Makefile.i386: Align functions to 16-byte boundaries if profiling is enabled. This will allow a fourfold reduction in the size of the profiling buffers.

Config doesn't generate lists of assembler source files so the lists to be mkdep'ed have to be given explictly. Only the standard *.s files are given, so the dependencies for gnu/fpemul/*.s are incomplete. *.S files would be handled right if config put them in CFILES. Don't define NPX. It was replaced by NNPX > 0 years ago. Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special case. Moving around the dependencies exposed a bug in make. It doesn't know that assym.s and ./assym.s are the same. Add a rule tell it.

Use the gensetdefs that is now in /usr/bin, it's a superset of the one in the kernel source, and that one is already used for modules. I don't _think_ this will hurt releases, aout-to-elf, etc, but it is possible. In all the cases I've looked at, config(8) has been generated straight after a make world, so if /usr/sbin/config exists and is the right version for the kernel, then we can pretty much count on /usr/bin/gensetdefs being there too.

This commit affects ELF kernels only. Remove "setdefs.h" and arrange to generate it automatically at ELF kernel build time.

When generating an ELF kernel, this is run just before the final link to generate "setdefs.h". Remove the init_sets() function from "setdef0.c", and its call from "machdep.c". Since "gensetdefs.c" calculates the length of each set, it is no longer necessary in an ELF kernel to count the set elements at kernel initialization time. Also remove "set_of_sets" which was used for this purpose. Link "setdef0" and "setdef1" into the kernel only if building for ELF. Since init_sets() is no longer used, there is no need to link them into an a.out kernel.

Load the kernel symbol table in the boot loader and not at compile time. (Boot with the -D flag if you want symbols.) Make it easier to extend `struct bootinfo' without losing either forwards or backwards compatibility. ddb_aout.c: Get the symbol table from wherever the loader put it. Nuke db_symtab[SYMTAB_SPACE]. boot.c: Enable loading of symbols. Align them on a page boundary. Add printfs about the symbol table sizes. Pass the memory sizes to the kernel. Fix initialization of `unit' (it got moved out of the loop). Fix adding the bss size (it got moved inside an ifdef). Initialize serial port when RB_SERIAL is toggled on. Fix comments. Clean up formatting of recently added code. io.c: Clean up formatting of recently added code. netboot/main.c, machdep.c, wd.c: Change names of bootinfo fields. LINT: Nuke SYMTAB_SPACE. Fix comment about DODUMP. Makefile.i386: Nuke use of dbsym. Exclude gcc symbols from kernel unless compiling with -g. Remove unused macro. Fix comments and formatting. genassym.c: Generate defines for some new bootinfo fields. Change names of old ones. locore.s: Copy only the valid part of the `struct bootinfo' passed by the loader. Reserve space for symbol table, if any. machdep.c: Check the memory sizes passed by the loader, if any. Don't use them yet. bootinfo.h: Add a size field so that we can resolve some mismatches between the loader bootinfo and the kernel boot info. The version number is not so good for this because of historical botches and because it's harder to maintain. Add memory size and symbol table fields. Change the names of everything. Hacks to save a few bytes: asm.S, boot.c, boot2.S: Replace `ouraddr' by `(BOOTSEG << 4)'. boot.c: Don't statically initialize `loadflags' to 0. Disable the "REDUNDANT" code that skips the BIOS variables. Eliminate `total'. Combine some more printfs. boot.h, disk.c, io.c, table.c: Move all statically initialzed data to table.c. io.c: Don't put the A20 gate bits in a variable.

Make the ELF kernel build produce a dynamic executable (!). This enables the in-kernel linker to access the _DYNAMIC data for doing loadable elf modules. The alpha kernel is already done this way, I've borrowed some of the hacks from there. This is primarily aimed at the 3-stage boot process which is intended to be able to do pre-loading of kernel modules. Note that the entry point isn't 0xf0100000 any more, it'll be a little further on - but this value is stored in the headers. I don't think this will be a problem, but I'm sure somebody will tell me if it is. :-) I'm not sure if btxboot is going to like this, it doesn't do proper ELF header checking and assumes that there are exactly two program header entries and that they are both PT_LOAD entries - a bad assumption.

Make the necessary changes so that an ELF kernel can be built. I have successfully built, booted, and run a number of different ELF kernel configurations, including GENERIC. LINT also builds and links cleanly, though I have not tried to boot it. The impact on developers is virtually nil, except for two things. All linker sets that might possibly be present in the kernel must be listed in "sys/i386/i386/setdefs.h". And all C symbols that are also referenced from assembly language code must be listed in "sys/i386/include/asnames.h". It so happens that failure to do these things will have no impact on the a.out kernel. But it will break the build of the ELF kernel. The ELF bootloader works, but it is not ready to commit quite yet.

This commit affects ELF kernels only. Remove "setdefs.h" and arrange to generate it automatically at ELF kernel build time. "gensetdefs.c" is a utility which scans a set of ELF object files and outputs a line ``DEFINE_SET(name, length);'' for each linker set that it finds. When generating an ELF kernel, this is run just before the final link to generate "setdefs.h". Remove the init_sets() function from "setdef0.c", and its call from "machdep.c". Since "gensetdefs.c" calculates the length of each set, it is no longer necessary in an ELF kernel to count the set elements at kernel initialization time. Also remove "set_of_sets" which was used for this purpose. Link "setdef0" and "setdef1" into the kernel only if building for ELF. Since init_sets() is no longer used, there is no need to link them into an a.out kernel.

Never strip the kernel. Recommend -Wimplicit in CWARNFLAGS next. There are still a few hundred potential arg mismatches because no function declaration is in scope. Don't duplicate option `-I.'. Remove null editing of the assembler source for all profiled objects. The required magic has been done since prehistoric times by an asm("mcount") declaration. Simplify the clean rule. Don't try to be clever about timestamps involving genassym. genassym's timestamp usually got ahead of assym.s's timestamp, so `make' almost always had to run genassym and compare *assym.s to decide that nothing needed to be done. The cost is reassembling a few files whenever genassym is rebuilt. Assembling is almost as fast as comparing. Always go through genassym.o to build genassym. This would have avoided numerous bugs involving mkdep -p. Now it just stops genassym from depending on the name of the temporary object file. Use ${CFLAGS} for building genassym. Mainly ${CWARNFLAGS} were missing.

./genassym >assym.s
Try to be a little smarter about touching the date on assym.s, so that if something changes which doesn't affect it, locore doesn't have to get rebuilt. This is at the cost of a genassym and a cmp in every compile, until someone can figure out how to make `make' smarter itself.

Removed historical dependencies on `Makefile'. They had rotted to being mostly for objects that have the fewest dependencies on `Makefile' (since they were mostly for utilities and objects generated from *.s and these don't depend on profiling flags). Give an explicit rule for building vnode_if.o. This fixes building it without ${PROF}. Use .ORDER instead of a stamp file to avoid building vnode_if.[ch] concurrently. Removed explicit dependencies that will be generated by `make' (.c.o) or will be generated by mkdep. Added missing dependencies of special objects on opt_global.h. Use ${NORMAL_C} instead of special rules for special objects where possible. FIxed dependencies of vers.o.

genassym.o: ${I386}/i386/genassym.c
Fixed missing dependencies of genassym.o, gensetdefs.o and vers.o on opt_global.h. This actually matters for genassym.o (it depends on at least SMP). Don't undefine KERNEL for compiling genassym.c. genassym.o really depends on KERNEL, and the prototype mismatches that required undefining KERNEL in rev.1.49 no longer exist. Compile gensetdefs* with the same flags as genassym*. External `gen' programs such linux_genassym should also use these flags (${GEN_CFLAGS}). Fixed missing dependency generation for gensetdefs.o. C sources for external `gen' programs should be added to GEN_CFILES to get their dependencies generated. Cleaned up flags definitions and use. All of ${CFLAGS} is now passed to mkdep and the assembler (both are actually variants of ${CC} and will ignore the irrelevant flags).

Use the gensetdefs that is now in /usr/bin, it's a superset of the one in the kernel source, and that one is already used for modules. I don't _think_ this will hurt releases, aout-to-elf, etc, but it is possible. In all the cases I've looked at, config(8) has been generated straight after a make world, so if /usr/sbin/config exists and is the right version for the kernel, then we can pretty much count on /usr/bin/gensetdefs being there too.

${SYSTEM_OBJS} genassym.o vers.o: opt_global.h
Create a special option file "opt_global.h" which is included by all source files via a 'cc -include opt_global.h ...' type arrangement. This means we can untangle certain header files. options.i386 has a placeholder until it has a real member so we can avoid having to teach config about it just yet. Reviewed by: bde

Don't include options MULTICAST or MROUTING in generic kernels. MULTICAST has no effect now, and MROUTING should never be defined by default. (Eventually the code should be dynamically loadable.) Also, allow for Pentium CPUs in GENERICBT kernels. Add an `install' rule to Makefile.i386, which looks like this: mv /kernel /kernel.old install -c -m 555 -o root -g root -fschg kernel / I'd like comments on whether or not you think it's a good idea to have the kernel be immutable by default; I'm happy either way. CVS:
1994-09-09 22:03:51 +00:00
I'm sick of the automatic rename of /kernel to /kernel.old while doing development that leads to lots of crashes during boot. I have made a 'reinstall' target (like in ports, and reinstall.debug) This is most useful if you want to keep /kernel.old as a known bootable kernel. If you test a new kernel and have to reboot for a fix, a 'make reinstall' will install the new kernel over the top of the old non-viable one, leaving the old one untouched. This is mainly meant for development, not general users.
