Raw Normal View History

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>

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.

Allow the source root `S' to be overridden by defining it only when it isn't already defined. It enables config(8) to create the kernel build directory where it wants.

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.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

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.

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.

Remove exception.o, swtch.o, support.o, conf.o and machdep.o from SYSTEM_OBS. They are now normal objects. Remove stale dependencies for the above now-normal objects and for locore.o and generate dependencies using mkdep. 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.

* Factor out the object system from new-bus so that it can be used by non-device code. * Re-implement the method dispatch to improve efficiency. The new system takes about 40ns for a method dispatch on a 300Mhz PII which is only 10ns slower than a direct function call on the same hardware. This changes the new-bus ABI slightly so make sure you re-compile any driver modules which you use.

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.

# omitted from SYSTEM_CFILES. They include setdefs.h, a header which
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.

# is generated from all of ${OBJS}. We don't want to have to compile
# everything just to do a make depend.
Borrow phk's axe and apply the next stage of config(8)'s evolution. Use Warner Losh's "hint" driver to decode ascii strings to fill the resource table at boot time. config(8) no longer generates an ioconf.c table - ie: the configuration no longer has to be compiled into the kernel. You can reconfigure your isa devices with the likes of this at loader(8) time: set hint.ed.0.port=0x320 userconfig will be rewritten to use this style interface one day and will move to /boot/userconfig.4th or something like that. It is still possible to statically compile in a set of hints into a kernel if you do not wish to use loader(8). See the "hints" directive in GENERIC as an example. All device wiring has been moved out of config(8). There is a set of helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98) that extract the 'at isa? port foo irq bar' from the old files and produces a hints file. If you install this file as /boot/device.hints (and update /boot/defaults/loader.conf - You can do a build/install in sys/boot) then loader will load it automatically for you. You can also compile in the hints directly with: hints "device.hints" as well. There are a few things that I'm not too happy with yet. Under this scheme, things like LINT would no longer be useful as "documentation" of settings. I have renamed this file to 'NOTES' and stored the example hints strings in it. However... this is not something that config(8) understands, so there is a script that extracts the build-specific data from the documentation file (NOTES) to produce a LINT that can be config'ed and built. A stack of man4 pages will need updating. :-/ Also, since there is no longer a difference between 'device' and 'pseudo-device' I collapsed the two together, and the resulting 'device' takes a 'number of units' for devices that still have it statically allocated. eg: 'device fe 4' will compile the fe driver with NFE set to 4. You can then set hints for 4 units (0 - 3). Also note that 'device fe0' will be interpreted as "zero units of 'fe'" which would be bad, so there is a config warning for this. This is only needed for old drivers that still have static limits on numbers of units. All the statically limited drivers that I could find were marked. Please exercise EXTREME CAUTION when transitioning! Moral support by: phk, msmith, dfr, asmodai, imp, and others

It is still possible to statically compile in a set of hints into a kernel if you do not wish to use loader(8). See the "hints" directive in GENERIC as an example. All device wiring has been moved out of config(8). There is a set of helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98) that extract the 'at isa? port foo irq bar' from the old files and produces a hints file. If you install this file as /boot/device.hints (and update /boot/defaults/loader.conf - You can do a build/install in sys/boot) then loader will load it automatically for you. You can also compile in the hints directly with: hints "device.hints" as well. There are a few things that I'm not too happy with yet. Under this scheme, things like LINT would no longer be useful as "documentation" of settings. I have renamed this file to 'NOTES' and stored the example hints strings in it. However... this is not something that config(8) understands, so there is a script that extracts the build-specific data from the documentation file (NOTES) to produce a LINT that can be config'ed and built. A stack of man4 pages will need updating. :-/ Also, since there is no longer a difference between 'device' and 'pseudo-device' I collapsed the two together, and the resulting 'device' takes a 'number of units' for devices that still have it statically allocated. eg: 'device fe 4' will compile the fe driver with NFE set to 4. You can then set hints for 4 units (0 - 3). Also note that 'device fe0' will be interpreted as "zero units of 'fe'" which would be bad, so there is a config warning for this. This is only needed for old drivers that still have static limits on numbers of units. All the statically limited drivers that I could find were marked.

Put on my asbestos suit and move $mach/conf/*.$mach to conf/*.$mach as hinted at in the previous config(8) commits. I've spoken about this with a few people and after the initial suprise wore off they thought it wasn't a bad idea. The upshot of it is that all the files*, Makefile*, options* files are all right next to each other in the hope that people making changes to one set will remember the others. Note, config(8) looks to sys/conf first, and falls back to sys/$mach/conf still, so this doesn't stop people working in subdirs for new platforms. But once it's in the tree it can be moved next to the other files so that the non-i386 platforms are (hopefully) treated a little better than as if they were "second class" ports. This does not change any user editable files. the config program is still run in the same directory as before, the per-platform files (GENERIC, LINT etc) are still in the same place.

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.

@gensetdefs ${OBJS}
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.

Remove exception.o, swtch.o, support.o, conf.o and machdep.o from SYSTEM_OBS. They are now normal objects. Remove stale dependencies for the above now-normal objects and for locore.o and generate dependencies using mkdep. 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 "nm | awk ..." instead of genassym(1) to generate symbol value headers. Symbol values are now represented using array sizes (4 arrays per symbol so that 16-bit machines can represent 64-bit values) instead of being raw binary values. Reviewed by: marcel

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.

genassym.o: $S/$M/$M/genassym.c

${CC} -c ${CFLAGS} $S/$M/$M/genassym.c
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.

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.

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.

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.

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.

Same for param.c: This is really a Merge in of NetBSD's Makefile.i386, here is the relevant rlog info: ---------------------------- revision 1.27 date: 1993/08/27 23:58:20; author: brezak; state: Exp; lines: +2 -2 Need LOAD_ADDRESS for depend pass. ---------------------------- revision 1.25 date: 1993/07/19 16:52:16; author: mycroft; state: Exp; lines: +3 -3 Add ${DEBUG} to CFLAGS and -f to dbsym. ---------------------------- revision 1.22 date: 1993/07/18 10:08:22; author: mycroft; state: Exp; lines: +5 -6 Change to work with new config stuff for specifying load address. ---------------------------- revision 1.20 date: 1993/07/18 09:47:40; author: mycroft; state: Exp; lines: +6 -5 Use new -T option to dbsym. ---------------------------- revision 1.17 date: 1993/07/11 08:42:22; author: cgd; state: Exp; lines: +2 -2 don't ignore errors from dbsym... it might say that, e.g. there's not enough symbol space! ---------------------------- revision 1.14 date: 1993/06/06 23:29:03; author: cgd; state: Exp; lines: +2 -2 make conf.o actually depend on conf.c... ---------------------------- revision 1.8 date: 1993/04/29 03:27:39; author: cgd; state: Exp; lines: +5 -10 use ed instead of ex. the script to use is identical, and we might want to switch back to using ex when our ex supports -. ---------------------------- revision 1.5 date: 1993/03/24 18:48:57; author: cgd; state: Exp; lines: +1 -1 now use absolute path for dbsym ----------------------------

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.

Borrow phk's axe and apply the next stage of config(8)'s evolution. Use Warner Losh's "hint" driver to decode ascii strings to fill the resource table at boot time. config(8) no longer generates an ioconf.c table - ie: the configuration no longer has to be compiled into the kernel. You can reconfigure your isa devices with the likes of this at loader(8) time: set hint.ed.0.port=0x320 userconfig will be rewritten to use this style interface one day and will move to /boot/userconfig.4th or something like that. It is still possible to statically compile in a set of hints into a kernel if you do not wish to use loader(8). See the "hints" directive in GENERIC as an example. All device wiring has been moved out of config(8). There is a set of helper scripts (see i386/conf/gethints.pl, and the same for alpha and pc98) that extract the 'at isa? port foo irq bar' from the old files and produces a hints file. If you install this file as /boot/device.hints (and update /boot/defaults/loader.conf - You can do a build/install in sys/boot) then loader will load it automatically for you. You can also compile in the hints directly with: hints "device.hints" as well. There are a few things that I'm not too happy with yet. Under this scheme, things like LINT would no longer be useful as "documentation" of settings. I have renamed this file to 'NOTES' and stored the example hints strings in it. However... this is not something that config(8) understands, so there is a script that extracts the build-specific data from the documentation file (NOTES) to produce a LINT that can be config'ed and built. A stack of man4 pages will need updating. :-/ Also, since there is no longer a difference between 'device' and 'pseudo-device' I collapsed the two together, and the resulting 'device' takes a 'number of units' for devices that still have it statically allocated. eg: 'device fe 4' will compile the fe driver with NFE set to 4. You can then set hints for 4 units (0 - 3). Also note that 'device fe0' will be interpreted as "zero units of 'fe'" which would be bad, so there is a config warning for this. This is only needed for old drivers that still have static limits on numbers of units. All the statically limited drivers that I could find were marked. Please exercise EXTREME CAUTION when transitioning! Moral support by: phk, msmith, dfr, asmodai, imp, and others

Be more consistant in using perl vs. perl5. We were using perl5 in the kernel builds so as not to confuse with perl4 when bootstrapping from old systems. I don't know if this is still applicable but it shouldn't hurt to be consistant at least. Also copy vnode_if.sh to vnode_if.pl. Doing a 'sh vnode_if.sh' when it was a perl script was kinda silly.

perl5 $S/kern/vnode_if.pl -c $S/kern/vnode_if.src
Use a seperate -c and -h mode. The vnode_if.c file is compiled only into the kernel while the vnode_if.h header is a bunch of inlines to call the code that is in the kernel. Generating the .h file on the fly is kinda bogus because it has to match the one compiled into the kernel. IMHO we should have kern/vnode_if.c and sys/vnode_if.h committed in the tree but that's another battle.

Hack: comment out the pull-in of src/sys/../share/mk/bsd.kern.mk as that breaks if you try and compile a kernel before building world, as is presently required to get past the signal changes. I don't particularly like doing this, but at least it will mean that a 'make world' will activate the gcc 2.95.2-specific option in bsd.kern.mk.
