* This is the kernel Lite/2 commit. There are some requisite userlanddyson1997-02-101-1/+1
| | | | | | | | | | | | | | | changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes. The system boots and can mount UFS filesystems. Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files. Mount_std mounts will not work until the getfsent library routine is changed.

| | | | | | as -0x4(%ebp) instead of as _APTD+0xffc(%ebp), and if GUPROF is defined, 8(%ebp) is now printed as 0x8(%ebp) instead of as GMON_PROF_HIRES+0x4(%ebp).
* Make the long-awaited change from $Id$ to $FreeBSD$jkh1997-01-1426-26/+26
| | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise.

* Attached vm ddb commands `show map', `show vmochk', `show object',bde1996-09-141-3/+20
| | | | | | | | | | | | | | | | | `show vmopag', `show page' and `show pageq'. Moved all vm ddb stuff to the ends of the vm source files. Changed printf() to db_printf(), `indent' to db_indent, and iprintf() to db_iprintf() in ddb commands. Moved db_indent and db_iprintf() from vm to ddb. vm_page.c: Don't use __pure. Staticized. db_output.c: Reduced page width from 80 to 79 to inhibit double spacing for long lines (there are still some problems if words are printed across column 79).
* Support statically attaching of ddb commands in non-ddb modules.bde1996-09-142-41/+111
| | | | | | | | | | | | | | | | The details are hidden in the DB_COMMAND(cmd_name, func_name) and DB_SHOW_COMMAND(cmd_name, func_name) macros. DB_COMMAND() adds to the top-level ddb command table and DB_SHOW_COMMAND adds to the `show' subtable. Most external commands will probably be `show' commands with no side effects. They should check their pointer args more carefully than `show map' :-), or ddb should trap internal faults better (like it does for memory accesses). The vm ddb commands are temporarily unattached. ddb.h: Also declare `db_indent' and db_iprintf() which will replace vm's `indent' and iprintf().

* Finally implement a simple commandline history in DDB.joerg1996-08-101-2/+71
| | | | | | | | Emacs-style line editing has already been there (did anybody ever notice this? :), so i `only' had to add ^P and ^N. The approach is fairly minimalistic, with the advantage of keeping the bloat as small as 864 bytes of .text and 16 bytes of .bss, plus 10*120 bytes malloc'ed history buffer at the first use.
* A small bit of defensive programming in case the panic is during processpeter1996-06-151-1/+5

| | | | | | | | | | | | | | | | | | | | Add more features to the one remaining to handle the job: + signed quantity. # alternate format - left padding * read width as next arg. n numeric in (argument specified) default radix. Fix the DDB debugger to use these. Use vprintf in debug routine in pcvt. The warnings from gcc may become more wrong and intolerable because of this. Warning: I have not checked the entire source for unsupported or changed constructs, but generally belive that there are only a few. Suggested by: bde

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.
